raster-tools

Useful tools to process rasters. Most of these tools work on a single-band float raster that represents a scalar field (eg. a digital elevation model).

Install using cargo-install:

cargo install raster-tools

Provides the following binaries.

raster-diff

Computes the difference raster between two rasters. The geo-transforms, and the dimensions of the rasters can be different; the two rasters are aligned, and the common region is calculated. Provides options to compute the stats, histogram of the difference, and/or create raster with the difference. The output raster has the same extents, and resolution as the first input and the data is the no-data-value (NAN) outside the common region.

raster-fill-nn

Computes and fill no-data-value of a raster using a collection of points via natural-neighbors interpolation. Uses the spade crate for the interpolation.

raster-stats

Computes first and second order stats (mean, min, max, std. dev.) of a raster. Optionally the stats can be computed on region contained inside each of a list of polygons. This is similar to gdalinfo -stats but also allows restriction by regions.

raster-tile

Computes and write web mercator (EPSG:3857) tiles of a raster. The output can be served as static files, and displayed using map UI libraries like openlayers .

TODO: provide sample openlayers code to display tiles

raster-mask

Computes a mask that represents the location where a raster has data. For RGB rasters (i.e. if the input has 3 bands), the no-data regions are where all values are 0 or the no-data value of the first band. In other cases, the last band is considered the mask.
