About the project

Sherlock is a geospatial search and discovery tool based on Elastic Search, STAC, and React.

This project exists in four parts:

1. This front end application
2. A compatible Elastic search index, documented here
3. The STAC api found here
4. The Sherlock Irregulars - metadata conversion framwork to bring non-STAC metadata into the STAC. View on Github

This project was built with the support of the NRCAN GeoConnections program

Demo

A demo of this project is available here:

Our index contains links to our own publically available assets, the Landsat STAC, and the ESA Coperincus mission catalog.

Getting Started

Prerequisites:

1. STAC-API

   Arturo STAC API is available here.

2. A compliant Elasticsearch Index. An example index schema available here.

Add-on Tools

Sherlock is designed to be interoperable with containerized add-on tools to facilitate common geospatial data operations in the cloud.

• Sherlock Wind - Retrieve ERA5 reanalysis wind vector data from a STAC item or Sherlock identifier.
• Sherlock COG - Convert raster data to Cloud Optimized GeoTIFF from a STAC item or Sherlock identifier.
• Sherlock SNAP - Process synthetic aperture radar (SAR) data with the ESA's SNAP Toolbox from a STAC item or Sherlock identifier.
