Fast raster extraction and manipulation in R

velox is an R package for performing fast extraction and manipulation operations on geospatial raster data. velox is fast because:

• All raster operations are performed in C++.
• Geometric operations are implemented with the Boost Geometry libraries.
• All data is held in memory.

velox is fully interoperable with the raster, sp, and sf packages.

Features

velox currently offers the following features:

• Raster value extraction given polygons, lines, or points
• Focal value calculation (i.e. moving window filters)
• Rasterization of polygons or lines
• Raster aggregation
• Cropping
• Image patch flattening and reconstruction
