Add map type definition to XML

[stoecker]

Should we add map and aerial/satellite image flags too. I think every source can be assigned to one of these three types. Displaying a little icon for the flag in wiki:Help/Preferences/Imagery would be nice and easier to understand what an entry is about.

See 14655#comment:91.

Current Suggestion: add an property "category" with supported values "photo", "map", "historicmap", "osmbasedmap", "historicphoto" and "other".

and maybe "gps" (thinking of the strava heatmaps)
The overlay flag needs to be separate then, as both gps and map can be a overlay or not.

[stoecker]

Well, I don't like "gps", as its outdated. In geodesy we use GNSS, but nobody outside the business knows what that is. Better term: "track", "measurement"?

Type is already taken BTW. We need something else as well: "variant", "class"?

This is maybe a bit out of scope of this ticket. We use "gps" all over in JOSM. A Launchpad search for "gps" gives 129 results. I think this must be decided later global for whole JOSM. Maybe the term GNSS becomes more popular one day when galileo is widespread used.

"Other" would be fine. There won't be a lot.

sources, which come to my mind for "other":

• OpenStreetMap GPS Traces
• Strava cycling heatmap
• Strava running heatmap
• Strava cycling and running heatmap
• Strava water sports heatmap
• Strava winter sports heatmap
• LPI NSW Imagery Dates (--> in australia, shows the date when the imagery was taken)

I think these rather count as "map" and "overlay":

• Locator Overlay
• QA No Address
• OSM Inspector: Geometry
• OSM Inspector: Tagging
• OSM Inspector: Places
• OSM Inspector: Highways
• OSM Inspector: Area
• OSM Inspector: Routing
• OSM Inspector: Addresses
• OSM Inspector: Coastline (EU)
• OSM Inspector: Public Transport - Stops
• OSM Inspector: Public Transport - Routes
• OSM Inspector: Water

[Klumbumbus]

We would need a type "multiple" too for wms_endpoint entries, which provide "map" and "photo" (and "other").

And what about a flag "osm_based" for sources based (mainly) on osm data?

• osm inspector entries
• QA No Address
• Opencyclemap
• openrailwaymap
• stamen
• waymarked trails
• carto
• Cambodia, Laos, Thailand, Vietnam, Malaysia, Myanmar bilingual
• ...

Also "historic" would be important to be able to filter these maps. But I also don't want more than one value for this.

My suggestion: "kind"
historicmap, osmmap, map, photo, other

[stoecker]

Last was me. Regarding mixed: simply don't specify a value?

[Klumbumbus]

Replying to stoecker:

Regarding mixed: simply don't specify a value?

Then you don't know if it is mixed or not yet specified.

[Klumbumbus]

aahh, https://josm.openstreetmap.de/mapsview?entry=Lantm%C3%A4teriet%20Economic%20Map%20%28historic%29 is a semitransparent map on historic aerial image :o

[stoecker]

Current list: "kind"
historicmap, map, osmbasedmap, historicphoto, photo, other
That's it (for now)?

ATM I think that's acceptable. If really necessary we can add types later.

For photo one could distinguish between true color and false color (infrared in most cases). But that would required an separate attribute again as it is independed from if the photo is historic or not.

What exactly means historic? Everything where a newer variant is available?

[stoecker]

From the ELI ticket I'd take suggestion "category" for the key.

category: historicmap, map, osmbasedmap, historicphoto, photo, other

[stoecker]

Sorry, forgot to answer last time.

Replying to Klumbumbus:

Mostly the Infrared is already in the name. I still think that overdoing the categorization will do more harm than good.

I try to imagine use cases in the editor for filtering

• historic: use case should be clear
• osmbasedmap: I.e. I don't want to see derivates
• map/photo: I only care for imagery.

What use case would color specification or finer details allow as a generic filter?

What exactly means historic? Everything where a newer variant is available?

I'd say so. And anything which is at least 20 years old :-)
