  • topo-change-uncertainty Public Forked from Cassandra-Brigham/topochange

    Open Source Python package for quantifying spatially correlated uncertainty in lidar topographic change detection. It decomposes vertical differencing error into bias, correlated, and uncorrelated components across spatial scales using nested variogram models and propagates uncertainty over user-defined regions.
