The plTools package is a set of programs for spatial analysis. The package includes:

• plMapcalc - raster layer calculator (web page, source);

• plClump4p - a program for creating connected components (clumps) based on a categorized geospatial layer (source).

plTools is available as a set of binary files for installation on Linux and Windows. In addition, it is made available as a QGIS plugin. Programs included in the plTools package can also be run from the command line or directly from QGIS.

The plTools package includes also a module that allows running plTools programs from the python language level. The module can be used in Python scripts, interactively in the interpreter, and in the Jupyter environment.

The plTools package uses GDAL, PROJ, ezDGAL, Argtable3 and TCC.

The plTools installer copies the executable files to a directory accessible from the user level or to all users. One system variable, PLTOOLSPATH, is defined during installation, indicating the program directory. The installation does not modify any other system settings.

The programs included in plTools are available under the GPLv3 license.
