Geographic data sources are desirable for ABS monitoring in order to identify:
The Geonames web service provides open access to georeferenced place name data for many countries.
The Google Maps API is available through Google Cloud. Users are allowed to geocode or reverse geocode up to 2,500 places per day for free. This will normally be perfectly adequate for sites that have low intensity daily use. Note that Google has recently updated its terms and the free allocation may have changed to a free credit of $200 per month.

Protected Planet provides access to the UNEP-WCMC World Directory of Protected Areas with data that can be downloaded in .csv, kml or shape file formats.
Individual country files can be downloaded from the relevant country pages. For example Kenya is https://www.protectedplanet.net/country/KE with the two letter country code marking the country. Note that the files are not available for commercial use without prior written permission from UNEP-WCMC.
