    11[[TranslatedPages]]
    2 = Main menu > Imagery =
    32
    4 This menu allows you to use various sources as a background layer in the main window.  Clicking on a green imagery menu item will automatically download the image from the server. Servers can be added and edited using the preference tab in the [wiki:/Help/Action/Preferences preferences]. Any new servers or changes would then displayed on the main imagery menu. By default, the major image providers are added.
     3= Imagery Menu=
     4This menu allows you to use various sources as a background layer in the [wikitr:/Help/MapView Mapview] such as aerial imagery, cadastral plans or maps rendered from OpenStreetMap data.
    55
    6 At present, the menu has following sections:
     6[[PageOutline(2-2,Table of contents)]]
    77
    8 == Image source ==
     8== Menu items ==
     9The Imagery menu has the following items:
    910
    10 [[Image(source:/trunk/images/imagery_menu.png)]] For each image source a menu point is added. When clicking on that menu you get a new layer with this image source.
    11 
    12 == Metacarta Rectified Image ==
    13 
    14 [[Image(source:/trunk/images/OLmarker.png)]] For use with Metacarta's [http://labs.metacarta.com/rectifier/ Map Rectifier].
    15 
    16 Clicking on this opens up a dialog box requesting an id. The id is obtained from either the page url or the WMS link. (for example,
    17 http://labs.metacarta.com/rectifier/rectify/73 -  the id would be 73)
    18 
    19 Note if you are using these images for editing then you need to ensure the image, and its method of rectification, are free of any copyright issues.
    20 
    21 == Blank layer ==
    22 
    23 [[Image(source:/trunk/images/blankmenu.png)]] In certain situations a blank imagery layer is needed (e.g. loading saved layers).
    24 
    25 == Installing Yahoo! aerial imagery downloader ==
    26 To use Yahoo! aerial imagery you will need to install a tool for interfacing with Yahoo to download tiles.
    27 
    28 === Windows ===
    29 
    30 ==== webkit-image ====
    31 On '''Windows''' use the [http://en.wikipedia.org/wiki/WebKit WebKit] based downloader called webkit-image as follows
    32 
    33 * [http://josm.openstreetmap.de/download/windows/webkit-image.zip Download webkit-image.zip]
    34 * Unzip it.
    35 * Move the contents so that the DLL files and the EXE file are somewhere "on your system path". The best way to achieve this might be to place them alongside josm. Keep the 'imageformats' subfolder alongside too (so ''all'' the contents of the zip).
    36 * Restart JOSM
    37 * Select the Yahoo menu point.
    38 You should start to get Yahoo! imagery (may take up to 30 seconds to start showing). If not, it may not be finding the DLL files correctly.
    39 
    40 '''Note:''' If you don't want to place webkit-image in your system path or the JOSM directory you don't have to. By editing the download program you can specify an absolute or relative path to the webkit-image executable. Examples:
    41 * '''webkit/webkit-image {0}''' - loads webkit-image.exe from the subdirectory '''webkit''' relative to the JOSM installation directory
    42 * '''D:/webkit/webkit-image {0}''' - uses webkit-image '''D:\webkit\webkit-image.exe'''
    43 
    44 === Linux kernel Operating Systems ===
    45 '''On Linux''' you can use different downloaders: ''gnome-web-photo'' or ''webkit-image''.
    46 
    47 ==== OpenSuSE, SuSE and SLES Distributions ====
    48 
    49 ===== release 11.3 (opensuse) =====
    50 * '''gnome-web-photo''' : this can be installed using '''yast'''
    51 * '''webkit-image''' : can be built for Qt if you have development tools installed. You will need to use '''yast''' to install:
    52  * libQTWebKit4-devel and friends
    53  * libqt4-devel and friends
    54  * pkg-config
    55  * other more general requirements depending on your build environment
    56 then follow the instructions below for ''Build from Source''
    57 * '''webkit-image-gtk''' : try instructions below for ''webkit-image (GTK+)'' after installing libwebkit (+friends) and gtk2-devel; you will need to edit an ''include'' line in '''webkit-image-gtk.c''' so that it points to ''gio-unix-2.0/gio'' and not just ''gio'', it should read:
    58 {{{
    59  #include <gio-unix-2.0/gio/gunixoutputstream.h>
    60 }}}
    61 Although the tool should now compile it may not scale tiles correctly within JOSM; use one of the other tools instead
    62 
    63 ==== gnome-web-photo for Fedora and Ubuntu ====
    64 gnome-web-photo is compiled and prepackaged for some distributions, including Fedora and Ubuntu.
    65 
    66 '''Attention:''' You have to select ''gnome-web-photo --mode=photo --format=png {0} /dev/stdout'' at the preferences dialog of the wms plugin.
    67 
    68 ===== On Ubuntu 8.10 'Intrepid Ibex' =====
    69 * Install gnome-web-photo through synaptic ''(version used 0.3-0ubuntu2)''
    70 * Select ''gnome-web-photo --mode=photo --format=png {0} /dev/stdout'' as the downloader at the bottom of the WMS preferences pane. Then you can choose the "Yahoo Sat" option from the WMS pull down menu to get the background to download. You might have to zoom out a bit if data is not available at the current zoom level.
    71 
    72 ===== On Ubuntu 9.04 'Jaunty Jackalope' =====
    73 
    74 The gnome-web-photo package in Ubuntu 9.04 has introduced bugs with JOSM, resulting in mis-aligned and distorted WMS imagery. This can be rectified by installing an older version of gnome-web-photo.
    75 
    76 While the common suggestion has been to compile and manually install gnome-web-photo, you can get away with installing the version from Ubuntu 8.10 instead.
    77 
    78 * [https://help.ubuntu.com/community/SynapticHowto#Adding%20or%20Removing%20Software Uninstall any existing version] of gnome-web-photo using Synaptic, or by issuing the following command on the command line: ''sudo apt-get remove gnome-web-photo''
    79 * Download an older version of [http://archive.ubuntu.com/ubuntu/pool/universe/g/gnome-web-photo/ gnome-web-photo from the Ubuntu Mirror].
    80  * gnome-web-photo_0.3-0ubuntu2_amd64.deb for 64 bit Ubuntu systems.
    81  * gnome-web-photo_0.3-0ubuntu2_i386.deb for 32 bit Ubuntu systems.
    82 * Once the file has downloaded, double click it to install it to your system. If for some reason this doesn't work, you can install it from the command line using ''sudo dpkg -i gnome-web-photo_0.3-0ubuntu2_*.deb''
    83  *Note, this may introduce problems when you upgrade to later versions of Ubuntu, so you may need to uninstall this package before you do so. You can do this by following the instructions in step one.
    84  *Every time you update your packages Ubuntu will attempt to update this package to the broken version. To stop this from happening add the following three lines to your /etc/apt/preferences (you may have to create this file)[[br]]''Package: gnome-web-photo''[[br]]''Pin: version 0.3*''[[br]]''Pin-Priority: 1001''
    85  * This may introduce dependencies problems, the package requires libxul0d. Run the command ''sudo apt-get -f install'' and it should fix any problems.
    86 * Select 'gnome-web-photo --mode=photo --format=png {0} /dev/stdout' as the downloader at the bottom of the WMS preferences pane. Then you can choose the "Yahoo Sat" option from the WMS pull down menu to get the background to download. You might have to zoom out a bit if data is not available at the current zoom level.
    87 
    88 ===== On Ubuntu 9.10 'Karmic Koala' =====
    89 
    90 The gnome-web-photo package in Ubuntu 9.10 does not seem to download any data.[[br]]
    91 Repeat the steps listed above for 9.04 by installing the old version of the package and it works.
    92 
    93 ===== On Ubuntu 10.04 'Lucid Lynx' =====
    94 * The gnome-web-photo(''(version used 0.8-0ubuntu2)'') package in Ubuntu 10.04 does not seem to download any data.
    95  * Goto Preferences>WMS>Add and give this address http://wms.latlon.org/?layers=yhsat&
    96 
    97 ===== On Ubuntu 10.04.1 'Lucid Lynx' =====
    98 * Install the latest gnome-web-photo(''(version used 0.8-0ubuntu3)'') package from Synaptic (or any other way you like).
    99 And select 'gnome-web-photo --mode=photo --format=png {0} /dev/stdout' as the downloader at the bottom of the WMS preferences pane in JOSM.
    100 
    101 =====  Troubleshooting: if you see white stripes =====
    102 * download [http://svn.openstreetmap.org/applications/editors/josm/webgrabber/gnome-web-photo-fixed gnome-web-photo-fixed] from OSM SVN repository
    103  sudo cp gnome-web-photo-fixed /usr/local/bin
    104  sudo chmod a+x /usr/local/bin/gnome-web-photo-fixed
    105 * install package netpbm
    106 * in JOSM -> Settings -> WMS, change "gnome-web-photo" to "gnome-web-photo-fixed" in the selection for download program.
    107 
    108 ==== webkit-image (QT) ====
    109 WebKit has some flavors, the main ones are QT-WebKit and WebKit-GTK+. See below for the GTK+ version.
    110 
    111 ===== On Debian unstable/sid =====
    112 
    113 If you installed josm with aptitude/apt-get you should get webkit-image-'''gtk''' installed automatically. If for some reason you don't have it, or it is not working correctly, you can install webkit-image-qt with the following command:
    114 
    115  sudo aptitude install webkit-image-qt
    116 
    117 If you have both webkit-image-qt and webkit-image-gtk installed and want to make sure that josm is using  webkit-image-qt you can either:
    118 
    119  sudo aptitude remove webkit-image-gtk
    120 
    121 or
    122 
    123  sudo update-alternatives --config webkit-image
    124 
    125 or
    126 
    127 go to the josm preferences, WMS tab and change "webkit-image {0}" to "webkit-image-qt {0}".
    128 
    129 ===== Building from Source =====
    130 * Install the following packages: build-essential libqt4-dev (>= 4.4.3) libqt4-webkit pkg-config
    131 * Download and compile (you may have to replace moc with moc-qt4, or /usr/include/qt4 with /usr/lib/qt4/include):
    132  wget http://svn.openstreetmap.org/applications/editors/josm/webgrabber/webkit-image.cpp
    133  moc webkit-image.cpp > webkit-image.h
    134  g++ -I /usr/include/qt4/ -I /usr/include/qt4/QtGui -I /usr/include/qt4/QtNetwork/ webkit-image.cpp -o webkit-image -lQtCore -lQtWebKit -lQtGui -s -O2
    135 * instead of the previous step, you can use the packaged Makefile:
    136  svn co http://svn.openstreetmap.org/applications/editors/josm/webgrabber
    137  cd webgrabber
    138  make webkit-image
    139 * Copy it to somewhere in your path:
    140  sudo cp -v webkit-image /usr/local/bin/
    141 
    142 : QT 4.2.1 from current Debian stable/etch is missing files, you'll absolutely need to compile. These files appear not before 4.4.3-1, that is in testing/lenny (checked in Ubuntu archives). You'll have to leave the "clean" state of our stable system to get the Debian testing or unstable package and it's dependencies. To do so, you'd like to add at least one line like
    143  http://ftp.debian.org/debian/ testing main contrib non-free
    144 : into your /etc/apt/sources.list file, or you'll not be able to even see the needed packages. Think twice before allowing any upgrade of existing packages to a more recent testing or unstable version, however, you'll have no choice to get Yahoo imagery working again with current JOSM revisions ...
    145 
    146 : Running aptitude I found following packages as mimimum additional install: libqt4-xml, libqt4-dbus, libqt4-script, libqt4-designer, libqt4-sql, libqt4-qt3support, libqt4-svg, libqt4-xmlpatterns, libqt4-help, libqt4-assistant, libqt4-test, qt4-qmake, libqt4-dev (all 4.4.3-1), but your experience may vary.

    183 The following code is an ebuild that installs webkit-image (QT) on a Gentoo Linux computer. See [http://linuxreviews.org/gentoo/ebuilds/ this Linux Reviews article] on how to install custom ebuilds. Using the path ''sci-geosciences/webkit-image/webkit-image-9999.ebuild'' to save the ebuild to within your local Portage overlay should work fine.

     70=== gray tiles ===
     71* if you have non-ACSII symbols in the path to your plugin folder in Windows (e.g. cyrillic letters in ''your name'' in `C:\Documents and Settings\[your name]\Application Data\JOSM\plugins`), a possible solution is to change ''your name'' to an equivalent short filename.

    222 [http://svn.openstreetmap.org/applications/editors/josm/webgrabber/webkit-image-gtk.c webkit-image-gtk.c].
    223 
    224 Libraries required: libgtk2.0-dev libwebkit-dev.
    225 
    226 To compile it, run: gcc -W -o webkit-image webkit-image-gtk.c `pkg-config --libs --cflags gtk+-2.0 webkit-1.0`
    227 
    228 (note:it builds but fails with "image == null" errors on Mandriva Linux, whereas Qt version works, on Gentoo too)
    229 
    230 '''success on the following Operating Systems'''
    231 
    232 '''comments:'''
    233 Ubuntu 10.04: Compiling http://svn.openstreetmap.org/applications/editors/josm/webgrabber/webkit-image-gtk.c a success! Putting the resulting webkit-image(made executable) in the directory /usr/local/bin/ . Doesn't load any yahoo tiles and just says "Exception occured". Once it showed some tiles but they covered tiny rectangles while everything else was "Exception occured".
    234 
    235 === Mac OS X ===
    236 
    237 ==== Prerequisites ====
    238 * Install XCode (free download from Apple after regstration, see http://developer.apple.com/mac/)
    239 * Install Qt SDK (free download from Qt Software, see http://www.qtsoftware.com/downloads/ “LGPL Downloads”, “Download Qt SDK for Mac”)
    240 
    241 ==== Installation ====
    242 
    243 Download Intel-only binary from http://www.lassitu.de/osm/webkit-image-r13262-qt-4.5-osx10.5.6.zip (MD5 checksum ecf2e2f044ce259af702247729468be1)
    244 
    245 Download PPC-only binary from http://westpol.dnsalias.org/webkit-image-r16071-qt-4.5-osx10.5.7.zip (MD5 checksum 2d00c2dbb1222b0293f7eaeccb1d5e8c)
    246 
    247 Or compile from source:
    248 
    249 1. Use svn to check out the grabber from http://svn.openstreetmap.org/applications/editors/josm/webgrabber
    250  '''$''' svn co http://svn.openstreetmap.org/applications/editors/josm/webgrabber
    251 2. In the Makefile, change the LDFLAGS line to read:
    252  LDFLAGS=-framework QtCore -framework QtGui -framework QtWebKit -framework QtNetwork
    253 3. Build the program with make:
    254  '''$''' make
    255 if it fails with webkit-image.h:15:2: error: #error "(The moc has changed too much.)"
    256 update the header files with
    257  '''$''' moc webkit-image.cpp > webkit-image.h
    258 4. Copy the ''webkit-image'' program to a directory that is part of the PATH. If you're not sure which directory to use, try this:
    259  '''$''' sudo mkdir -p /usr/local/bin
    260  '''$''' sudo cp webkit-image /usr/local/bin
    261 
    262 : Unix programs (and Mac OS X) look for programs to execute in a list of directories. This search list is kept in the PATH environment variable. By default, PATH is set to ''/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin''. To check the current value of the PATH environment variable, use ''echo $PATH''. You can copy the ''webkit-image'' program to any of the directories listed in PATH, and JOSM will automatically find them.
    263 
    264 ==== Configuration ====
    265 
    266 Since July 2009, no further configuration is necessary. If you've installed ''webkit-image'' in a directory not in the PATH, you need to modify the path given in the Downloader text box at the botton of the wemplugin preferences page.
    267 
    268 === FreeBSD ===
    269 
    270 If you have JOSM installed from ports collection, then you already got webkit-image (QT) compiled and installed, and Yahoo imagery will work out of the box.
    271 
    272 == Source ==
    273 You can get source of the WMS plugin from Subversion:
    274 
    275 {{{svn co http://svn.openstreetmap.org/applications/editors/josm/webgrabber/}}}
    276 
    277 = Using the WMS plugin =
    278 
    279 * Load / Download openstreetmap data and go to your favourite area
    280 * Show the 'Layers' panel if it isn't showing already (Click the toggle button: [[Image:Liste aller Ebenen.png]])
    281 * Click the menu option "WMS → Landsat" (or whatever named WMS server you want to use) This should cause it to create a new imagery layer.
    282 * Wait a few moments for it to begin fetching image tiles.
    283 
    284 As you pan around it will download more tiles. It also seems to remove tiles which are out of viewing area, to free up memory.
    285 
    286 To remove the imagery and stop all WMS downloading, select the layer and click the trash can button. You can also temporarily toggle visibility of the layer (keeps imagery in memory). Right click on the layer (in the layers panel) to access further WMS layer options.
    287 
    288 When your WMS layer is selected, the data layer is shown as deselected (dark grey). Simply select your data layer again (often called 'unnamed') to restore normal colours. It is also possible to display the WMS layer "above" the data layer, which will hide the data layer completely. Use the up/down arrows to fix the ordering.
    289 
    290 You can adjust the positioning of the imagery by clicking [[Image:Adjust WMS-Layer.png]] button on the left. In this mode you can drag and drop the WMS layer. Press the button again to lock it in place. This can be useful if the imagery appears to be offset from reality, but note that your GPS unit isn't perfect. A bad GPS signal can cause an entire trace to have an offset from reality, so you may find it useful to check also by downloading other GPS traces recorded for the area.
    291 
    292 You may need to adjust your map colours ('Edit' menu -> 'Preferences') to be darker or lighter, to contrast with the images you are using.
    293 
    294 == Basic troubleshooting ==
    295 Things to try in case of problem.
    296 
    297 === no image appears, even after waiting a bit ===
    298 * adjust zoom level so that the scale in the top left says ~150m, delete the layer (trash can icon), add it again from the menu.
    299 * The plugin may not find the DLL files. Check you have placed all of the webkit-image zip file contents them somewhere on the system path.
    300 
    301 === images at bad resolution from Yahoo ===
    302 * adjust zoom level as decribed above. Note that in most regions Yahoo imagery has a lesser resolution than Google Maps.
    303 
    304 === Exception occurred - red tiles ===
    305 * This can mean the WMS server is temporarily not available. Landsat and OpenAerialMap seem to be prone to periods of non-availability. Delete the WMS layer and try again 10 minutes later.
    306 
    307 === error : bad parameters - red tiles ===
    308 * Check that configuration -> projection is set to EPSG:4326 or Mercator.
    309 
    310 === gray tiles ===
    311 * if you have non-ACSII symbols in the path to your plugin folder in Windows (e.g. cyrillic letters in ''your name'' in C:\Documents and Settings\''your name''\Application Data\JOSM\plugins), a possible solution is to change ''your name'' to an equivalent short filename. To find this open a command window and do
    312  dir /x "C:\Documents and Settings"
    313 In its output the column to the left of ''your name'' should contain short version of ''your name'', let it be for example ''9335~1''. Add a line to the batch file starting JOSM:
    314  rem   Contents of start_JOSM.cmd
    315  set APPDATA=C:\Documents and Settings\''9335~1''\Application Data
    316  start javaw -jar josm.jar
    31784
    31885== Caching ==
    319 To reuse the tiles over JOSM sessions without having the reload them from the server, right click on the WMS layer and set a bookmark. During the next session, select the new WMS created by the bookmark in the WMS memu. Additionally, you may want to modify the following values in the preferences :
    320 * cache.wmsplugin.expire -1 : this is a time in second until the tiles are invalidated. -1 means "never flush".
    321 * cache.wmsplugin.maxsize 999999999 : maximal size of the cache (probably in MB)
    322 Even though you have to download an area "manually", you can work offline using this technique.

    32897Before you start with your own images, it might be a good idea to start with Landsat data so you'll learn how to work with these downloaded images.
    32998
    33099To work with your own images in JOSM:
    331 
    332100* upload your aerial image / scanned old map to either
    333  * Geothings at http://warper.geothings.net/ or
    334  * MetaCarta at http://labs.metacarta.com/rectifier/
    335  * '''Note:''' please read their privacy/copyright notes first
    336 * rectify it on their site so it "fits with reality"

     106 * **Note**: please read their privacy/copyright notes first
     107* rectify it on their site so it ''fits with reality''
    337108* XXX - wait for the image to be processed?
    338109* remember the metacarta id (look at the URL in your browser)
    339 * in JOSM, load some openstreetmap data of the expected image area (to be in the right "clipping range")
     110* in JOSM, load some openstreetmap data of the expected image area (to be in the right ''clipping range'')
    340111* click on Rectified Image and enter the id in the upcoming dialog
    341112
    342 If the "clipping range" was wrong, you might see just nothing. In this case zoom out and retry the download.

    344 == Adding a WMS Server ==
    345 
    346 '''Do not use copyrighted material, unless you have the right/permission to do so (see the Licensing section below)!'''
    347 
    348 To add a new WMS Server, use the Menu: 'Edit' menu -> 'Preferences' and click on the WMS tab. Now you can add / remove WMS server URL's.
    349 
    350 A WMS server typically can provide different projections, subsets of data, etc., so you may need to experiment with the URL settings to get the best results.
    351 
    352 == Adding presets for objects and {{tag|source||yahoo_wms}} ==
    353 
    354 It can be useful to let other users know what your data is based on by adding {{tag|source||yahoo_wms}}. This can be quickly done by creating a JOSM [http://josm.openstreetmap.de/wiki/TaggingPresets tagging preset] for roads, woodland, etc and {{tag|source||yahoo_wms}}.
    355 
    356 Once this is setup, it is simple to apply custom combinations of tags to an node, way or area in JOSM:
    357 
    358 * Download the [[Image:Yahoo-road.png]] Yahoo road icon.
    359 * Open your favourite text editor and insert the following:
    360  <annotations>
    361    <item name="road-source" icon="[PATH TO ICON]\Yahoo-road.png">
    362        <key key="source" value="yahoo_wms" />
    363        <key key="highway" value="road" />
    364    </item>
    365  </annotations>
    366 
    367 * Save it as yahoo-presets.xml
    368 * Open JOSM
    369 * Open the Preferences, go to the Map Settings (3rd tab)
    370 * Add your file at the "Tagging Preset Sources"
    371 * Restart JOSM
    372 * If you want, you can put the preset in your toolbar for quick access (Preferences, Toolbar customization)
    373 * You might also want presets for things like [[Image:Yahoo-farm.png]] {{tag|landuse||farm}} and/or [[Image:Yahoo-stream.png]] {{tag|waterway||stream}}
    374 * Download the above icons and add new <item> entries to your yahoo-presets.xml file
    375 
    376 == Remote control ==
    377 
    378 Since version 22677 the WMSPlugin will register an additional remote control command "wms" if the [[{{{RemoteControl:plugin|JOSM/Plugins/RemoteControl}}} | RemoteControl]] plugin version 22675 or newer is loaded.
    379 
    380 The "wms" command instructs JOSM to open a WMS layer in the same way as with the "rectified image" menu command.
    381 
    382   GET /wms?title=foobar&urldecode=false&url=...
    383 
    384 where
    385 
    386 {|{{Prettytable}}
    387 !parameter
    388 !required/
    389 optional
    390 !meaning
    391 |-
    392 |url
    393 |R
    394 |WMS URL in the usual format. This must be the last parameter.
    395 |-
    396 |title
    397 |O
    398 |Title (name) of WMS layer. If not specified the title will be "remote WMS".
    399 |-
    400 |urldecode
    401 |O
    402 |Disable URL-decoding of URL value if true. All other values will be URL-decoded anyway.
    403 |-
    404 |cookies
    405 |O
    406 |Can be used to specify cookies for the WMS request.
    407 |}
    408 
    409 Note: The "url" parameter must be the last one. Everything after url= will be used as the WMS URL. It is not mandatory to URL-encode the value, but the WMSPlugin will try to URL-decode it unless urldecode=false is specified. If you notice that the decoding modifies the URL in an unwanted way, add "urldecode=false" before the "url" parameter.
    410 
    411 This remote control function can be disabled by setting preferences value
    412 
    413   wmsplugin.remotecontrol=false
    414 
    415 or by using the checkbox "Allow remote control (reqires remotecontrol plugin)" in the preferences editor.
