Earth Observation API
This repository is a sample application for my thesis work, spring 2016, at Norwegian University of Science and Technology (NTNU).
Sign up at the satellite imagery services
To use the application you need to be signed up at the different satellite imagery services.
Set up credentials
After signing up and retrieving the necessary credentials from the service, remember to fill in the credentials in the config.js
file. The endpoints
objects stores one object for each of the services.
Run with only a few of the services
Simply comment out the services found in app.js
const endpoints = [
// AstroDigital,
// DigitalGlobe,
// ECHO,
// PlanetLabs,
SciHub,
// UrtheCast
];
// Running the application with SciHub only.
Define area-of-interests
The two areas already included in the application are Oslo, Norway and San Francisco, US. If you want to add your own area-of-interests, add them to the locations
object in config.js
. A location is defined as follows:
locationName: {
polygon: <GeoJSON Polygon>
}
Where the <GeoJSON Polygon>
has the full structure as defined here. A convenient tool for defining GeoJSON polygons can be found here.
Installing dependencies
The application uses Node.js
and the dependencies can be installed using:
$ npm install
Running the application
The application can be run with the following command.
$ npm start <locationName>
# For Oslo, Norway
$ npm start oslo
The <locationName>
should match the location defined in the locations
object in config.js
. Please note that this is case-sensitive.
The output from the application can be found in outputs
with the following filenames: location_endpoint.json
. For example: oslo_SciHub.json
.
