SpatialData provides an interface to Proj.4 (cartographic projections library) for converting coordinates among a variety of geographic projections.

Spatialdata

Spatialdata is a C++ library for

• interpolating values for spatially distributed data,
• converting coordinates among geographic projections using Proj,
• nondimensionalization of quantities,
• specification of units via Pyre (optional).

This library is used in the finite-element code PyLith (https://github.com/geodynamics/pylith). The primary focus is specification of parameters that vary in space, such as values for boundary conditions and parameters of constitutive models. This provides a specification of these parameters independent of the discretization.

Dependencies

• GNU build tools w/C++ and C compilers
• Proj cartographic projections library (v6.0 or later) (http://proj.maptools.org)
• [Optional] Pyre 1.0 and NumPy
• [Optional] CppUnit (for unit testing)
