HTTP API Processes - Clean/Simplify

This section contains the following topics:

• Generalise (Douglas-Peucker N) - Generalises geometry using a variation of the Douglas-Peucker algorithm that is limited by the number of output points
• Generalise (Douglas-Peucker) - Generalises geometry using the Douglas-Peucker algorithm
• Generalise(Perpendicular Distance) - Generalises geometry using the Perpendicular Distance algorithm
• Generalise (Radial Distance) - Generalises geometry using the Radial Distance algorithm
• Generalise (Reumann-Witkam) - Generalises geometry using the Reumann-Witkam algorithm
• Remove duplicates (by expression) - Removes duplicate items based on an expression
• Remove duplicates (by geometry) - Removes duplicate items based on their geometry
• Remove self-intersections - Removes self-intersections, eg a bow-tie
• Remove short segments - Removes segments shorter than a tolerance
• Remove spikes - Removes vertices that cause a spike
• Remove straight segments - Removes vertices between straight, or near straight segments
• Simplify - Simplifies the geometry of an item, so that it matches the OGC 'simple' form

Note: Some properties in the above processes are mandatory and some are optional. Mandatory properties are shown in RED.
