About this technology
Overview
The DAG software implements a generalized, cloud-enabled web service for the extraction of converted geophysical values from satellite imagery layers being served out via Tiled-WMS imagery servers and the computation of geo spatial analytics on the data returned. Analyses supported at present focus on spatial and temporal summary statistics for user selected bounding box regions, time ranges and variables of interest. The DAG service can be invoked both directly programmatically via calls to the API and via the Flask Open-API interface implemented by DAG. Outputs can be consumed by various client applications, including visualization and other tools.
