Reactive Presence Data Property — Display Caveats

Reactive Presence Data Property — Display Caveats

Presence data property now reactive, dynamically displayed on yearly basis. Since presence property is binary, display driven by boolean-based function, reading 'true' / 'false' yearly, displaying icon if / when 'true' is red. See commit and gif:

There are caveats / issues remaining:

• 1.svg loses coloring when loaded into the dashboard (potentially have @shannonkjones look into this?)
  • current build now using "PoPS" bug icon (imo: PoPS .svg >>> slf .svg) current build]
• 2. multiple pest icons displayed for single countries, instead of one icon (e.g., at center of country) (see below example)
  • could potentially be simple layer styling issues (i.e. Mapbox Studio) that I am just unaware of
    • will continue looking into
    • see figure below :  

      
      
      Figure shows how icons are added to each separated polygon, even if belonging to same, single country. Seemingly occurs when country's polygon/vector boundaries become split into separate territories (based on geojson coordinates), then treated as new region(s) to display pest presence.

Wait for @ChrisJones687's thoughts to proceed?

@gcmillar To clarify: the SLF.svg is converted to a black image, but the PoPS.svg displays with colors?

(1) Are they being loaded identically?
(2) Pure speculation: It is possible that the SLF vector is just too complicated to be displayed at that small size. MapBox may automatically convert to a solid version of the sprite if the vector details can not be resolved for the given image size and screen resolution.

My troubleshooting strategy would be to make a VERY simple svg (maybe try an SLF outline with single fill color). If that works, then I think you could try adding a little bit more detail (if desired). If you need help, let me know.

@gcmillar I happened across this and think it may be useful. https://docs.mapbox.com/help/troubleshooting/studio-svg-upload-errors/

@shannonkjones Thank you !! I did actually end up using that process a few days ago, but for the green PoPS icon. I did try it with the SLF icon at first but didn't have any luck with it. I'll definitely revisit soon after the meeting tomorrow.

Relatedly, issue 2 (above) has now been fixed. I was able to calculate the centroids for all countries, and create a function to overwrite the default icon anchor position, to instead display only one icon per country, at the respective country's centroid.
