tobler is a python package for areal interpolation, dasymetric mapping, change
of support, and small area estimation. It provides a suite of tools with a
simple interface for transferring data from one polygonal representation to
another. Common examples include standardizing census data from different time
periods to a single representation (i.e. to overcome boundary changes in
successive years), or the conversion of data collected at different spatial
scales into shared units of analysis (e.g. converting zip code and neighborhood
data into a regular grid). tobler is part of the PySAL family of packages for
spatial data science and provides highly performant implementations of basic and
advanced interpolation methods, leveraging shapely to optimize for multicore
architecture. The package name is an homage to the legendary quantitative
geographer Waldo Tobler, a pioneer in geographic interpolation methods, spatial
analysis, and computational social science.
