Introducing the Query API

Introduction

The Koordinates APIs allow users to query data hosted on Koordinates via simple HTTP requests. They are accessible to any user who has a valid login to Koordinates.

Authentication

You need an API key to access the hosted data, and this key needs to be passed with each request via the key GET parameter.

It's a good idea to use separate keys for each application you build. API Keys can be generated by heading to the API page under your user Dashboard.

Available APIs:

  • Vector Query - look up a point location and get information from one or more vector layers about nearby features.
  • Raster Query - look up a point location and get back information from raster/grid data about the values in each image band.
  • Set Query - look up data for multiple layers in a set.
