SATC OGC Services example project

This project allows to use STAC API server as an input catalog for available rasters. GeoTrellis server translates input OGC queries into STAC queries and reads requested items assets respectively.

GeoTrellis server requires the STAC Layer extension usage.

Project description

List of commands available to run from this folder:

• make run - starts the postgres database for Franklin, applies all Franklin migrations, inserts the ./catalog, starts the Franklin server and start the geotrellis-server that is configured to work with this layer.
• make run-geotrellis-server - runs the GeoTrellis OGC server

For more details about available commands you can look into the Makefile.

Compatible STAC Catalogs

In the ./catalog folder you can find a GeoTrellis server compatible static STAC catalog with the STAC Layer extension, that can be imported into Franklin.

The new STAC configuration description

stac-lc8-red-us = {
  type = "stacsourceconf"
  name = "stac-lc8-red-us" // OGC Layer name
  title = "Landsat LayerUS Red"
  layer = "layer-us" // STAC Layer
  asset = "B4" // STAC Asset to read
  asset-limit = 1000 // Max assets returned by the STAC search request
  source = "http://localhost:9090/" // Path to the STAC API endpoint
  default-style = "red-to-blue"
  styles = [
    {
      name = "red-to-blue"
      title = "Red To Blue"
      type = "colorrampconf"
      colors = ${color-ramps.red-to-blue}
      stops = 64
      }
  ]
}

Such layer can be used within the MAML expression.
