Agency explorer map

Context

• Related to Homepage map + search pdap.io#190
• Related to Data Source Identification 2025 plan data-source-identification#108
• Replaces Search results: display agencies pdap.io#202
• We have previously used maps as a vector for searching; this is about understanding the data landscape!
• Goals:
  • help people browse agencies and see what we have, what is unknown, what is missing (we searched and did not find it)
  • give people a general sense of what is published in a given agency or region
  • compare the presence of a particular
• wireframe needed

Front end

• a dedicated page with a map for exploring full-screen
• once you zoom into a certain level, display agencies with color-coding
• there are filters for different data categories or types
• an overlay lists agencies which can be clicked
• clicking an agency opens an overlay with the presence or absence of each record type, and links to the source(s) where present
• show all record types with color coding
  • present: nice color
  • missing: bad color
  • unknown: gray
• for missing types, show when we last found it
• give people the option to filter the entire map by record types/categories

Back end

• the concept in the database of "not found" data based on a "check" for:
  • searched agency_described
    • or location_described? either? both?
  • searched record_type
  • search_method(s)
  • searched_at
  • status? like not found, found, removed
• API endpoints for creating checks, getting the result of the last check
  • make sure we're checking our own database for aggregated sources and agencies upstream (i.e. county, state, federal)
  • make sure we're checking the sources we already have to see if they go missing

Open questions

All is up for discussion!

@maxachis would you mind sharing your thoughts on the back end portion of this distant issue?
