SWIG wrappers for the Community Sensor Model

This repository contains SWIG wrappers for the CSM. The wrappers are currently only be created for Python, though many other languages can be supported.

Building, Installing, and Testing

• Ensure that the library is installed
• (Optional) Install the USGS CSM_CameraModel libraries to ensure that this wrapper is able to do something.
• mkdir build
• cd build
• cmake ..
• cmake --build .
• cd python
• python setup.py install
• ctest

Usage

The CSM is designed so that plugins with a common insterface are dynamically loaded. This wrapper is designed to continue that philosophy. Therefore, loading an implementation of the interface is a little different than a standard python import.

import csmapi
import ctypes

# THis dynamically registers this plugin with the CSM API.
lib = ctypes.CDLL('path_to_the_csm_plugin_library.so')

# The two methods that are implemented are getList and findPlugin
plugin_list = csmapi.Plugin.getList()

# Should be greater than 0
print(len(plugin_list))

Issues

The dynamic cast from the model up the inheretance tree to RasterGM has not yet been implemented. The test_functional.py (in tests) demonstrates how the returned object is a pointer to a Model. This needs to be dynamically cast (I think with a %factory directive) to the RasterGM class that contains the full suite of methods.
