Map issues various #3

Closed tmfrnz closed 4 years ago

tmfrnz commented 4 years ago

@jrfep in addition to #1, here a list of other maps with problems:

[x] S1.2: no layer specified in configuration data/config/groups.json#L1247
[x] MFT1.1: if river deltas should not be mapped as areas but as locations, then the layer should include points but not circular areas (that are only circular in the projection they were drawn but no longer once re-projected)
[x] SM1.2: no layer specified in configuration data/config/groups.json#L1389

S1.2 does not have a map (it is distributed everywhere, both in land and seafloor), not sure if it is better to show no map at all, or a map all in red? Would it be possible to display an image instead of the map, like in the biome pages?

jrfep commented 4 years ago

Regarding MFT1.1: there are two or three other maps with point locality data, is there a way to add point markers for those?

Yes it would be possible to show an image, however we would probably prefer to make the map red everywhere. Ideally this would come out of a GIS layer (as this will not require any additional work, also we can use that same layer for our analysis)

We could indeed also add point markers however another option would be to map the true (albeit small) extent of these groups as areas and use some additional highlight layers (ie buffered areas) to enhance the data's visibility as suggested here in option 2: https://github.com/red-list-ecosystem/typology-map/issues/30

Benefits would include

consistent representation
consistent handling of layers in the analysis module (calculating areas)
small additional effort
preparation of buffered areas for highlighting and interaction could be scripted (for round circles this would have to be done in the right projection and units of course)

This is what it might look like (we would probably go for a similar style when using map markers, however marking the circles center)

jrfep commented 4 years ago

Added a placeholder rectangle for S1.2 and copied the SM1.1 layer for SM1.2 (very similar distribution)

MFT1.1 is now based on Deltas at risk layer !
