Earth Search by Element 84

earth-search.aws.element84.com

A public STAC API over the satellite imagery archives hosted on AWS Open Data - Sentinel-2, Sentinel-1 GRD, Landsat Collection 2 Level-2, NAIP aerial photography and the Copernicus 30m and 90m DEMs - letting you find scenes by area, date and cloud cover and read back their footprints, metadata and direct S3/HTTPS asset URLs.

Ask with this source

A prompt for your agent that names this source and how to call it through the crw MCP.

  • Scene statistics

    Use Earth Search by Element 84 (earthsearch) from fastCRW Pergamon, capability "Scene statistics" (aggregate). You want counts or a distribution over an area or period - how many cloud-free scenes exist, when coverage starts and ends - and not the scene records themselves. Example options: collections=sentinel-2-l2a, aggregations=total_count,datetime_min,datetime_max, bbox=-122.6,37.6,-122.3,37.9. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "earthsearch" and capability "aggregate". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Available aggregations

    Use Earth Search by Element 84 (earthsearch) from fastCRW Pergamon, capability "Available aggregations" (aggregations). You are about to call scene statistics and need the aggregation names that collection accepts. Example options: collection_id=sentinel-2-l2a. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "earthsearch" and capability "aggregations". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Collection detail

    Use Earth Search by Element 84 (earthsearch) from fastCRW Pergamon, capability "Collection detail" (collection). You have settled on a collection id and need its bands, assets and date range before you search it. Example options: collection_id=sentinel-2-l2a. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "earthsearch" and capability "collection". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>

  • Browse a collection's scenes

    Use Earth Search by Element 84 (earthsearch) from fastCRW Pergamon, capability "Browse a collection's scenes" (collection-items). You are walking a single archive in order - the newest scenes, or a date window page by page - and need neither cross-collection search nor GeoJSON-shape matching. Example options: collection_id=sentinel-2-l2a, bbox=-122.6,37.6,-122.3,37.9, datetime=2024-06-01T00:00:00Z/2024-06-02T00:00:00Z. Use the crw MCP tools: crw_find_data to confirm the source and its options, then crw_get_data with provider "earthsearch" and capability "collection-items". Tell me the credits used and cite the licence from the response. If the crw MCP tools are missing, install them with: npx -y crw-mcp install --api-key <your fastCRW API key>
