CoverageDataInPoint Service - v1.4
- Scott Jonker
- Clara Baker
Introduction
The CoverageDataInPoint service will take a layer and lat/lon coordinates and return the earliest and latest collection date and ground sample distance (pixel size) of all intersecting discrete images. This service is useful to determine the full date range of available images over a given point.
Similar functionality can be achieved by using the more robust FindImageInPoint service which will identify discrete images intersecting the input coordinate and provide both collection dates and GSD (amongst all metadata attributes) all while searching one or more layers.
Technical Details
This service requires a point (lat/lon coordinates) and the desired imagery layer. It will return a JSON file containing the earliest capture date, latest capture date and ground sample distance (GSD).
