The PROWL system has all the logic built in to it. All your planning software needs to do is access the service with the following parameters;
The starting Longitude
The starting Latitude
Your username
Your password
Your query type
Then the PROWL system will then respond with the GPS vertices of polygons that are within the 50 metre tile of your requested co-ordinates – in GeoJSON. Each polygon represents an object or hazard, is categorised and tagged, and may have been submitted by another user, or available from an existing online source.
Your flight planning software (or the drone, if it is supported) can then plan the flight path around the objects that PROWL has revealed.
The response from PROWL will be a series of GPS location points, with a label to indicate the object type, and other tags that the data provider has submitted. The small amount of data in the response allows drones with limited computing power and storage to handle the mapping path assessment.
