Static assets source code

A variety of static assets are used in HDX Signals. These are all stored in the HDX Signals prod container on Azure, in the input folder. Some of these assets are produced through source code in this folder, which can be updated with update_assets.yaml GitHub Action. A few of the assets are provided manually. The assets used in Signals are briefly described below, including how they are updated.

Assets

  • adm0: Admin 0 polygon layers for use as a base layer in maps. Each location has an adm0/{ISO3}.geojson file that can be used. Updated in update_adm0_sf.R
  • centroids: Admin 0 centroids that are added to the final Signals dataset. These are not published to HDX, and are just used for the webmap on the HDX website. Updated in update_centroids_sf.R.
  • cities: Cities spatial data for use in maps. Updated in update_cities_sf.R.
  • acled_info.parquet: Data on the start date of ACLED coverage for locations and the web URL to the location page. Updated in update_acled_info.R.
  • asap_iso3.parquet: ASAP0 to ISO3 mapping file. Used in location_codes.R.
  • gaul1_asap_FAO_Mapping_v8.csv: CSV file provided directly by JRC to map ASAP0 IDs to GAUL codes, which can then map to ISO3. Used to create asap_iso3.parquet.
  • hrp_locations.parquet: Vector of ISO3 codes for HRP locations. Script will need adjustment when new HRP locations are created. Updated in update_hrp_locations.R.
  • idmc_urls.csv: Data on the URL for IDMC locations. Manually provided by the IDMC via email and uploaded to the Azure container.
  • indicator_mapping.parquet: Mapping from indicator_id to various other information necessary for email generation, such as Mailchimp settings and subject line and title for emails. Updated in update_indicator_mapping.R
  • iso3_map_settings.json: Map settings that determine legend placement for dynamic maps. Updated in update_iso3_map_settings.R
  • locations_metadata.parquet: Metadata for locations, such as their name, regions, centroids, and other information that are joined up to create the final Signals dataset and metadata file on HDX. Updated in update_locations_metadata.R.
  • locations.parquet: All ISO3 codes for locations covered by HDX Signals. Updated in update_locations.R.
  • un_geodata_complex.geojson: UN admin 0 polygons, used to create the base layers in adm0. Secured privately, and updates will need to be made upon request to the UN Geo Hub, where only the simplified boundaries are available for public downloaded.
