It focuses on reading and writing data in standard Python IO style and relies upon familiar Python types and protocols such as files, dictionaries, mappings, and iterators instead of classes specific to OGR. Written by Aoife Curran. This means that if the lidar derived height were 0, the estimated ground truth height would be close to 3, which may suggest some systematic offset between the lidar and ground measurements of height. Finally, let's use geopandas' to_crs function to project the data to EPSG:3310, California Albers, which is appropriate for displaying and calculating distances in California. 0 kB | noarch/geopandas-0.
