“All maps are wrong. Get used to it! Maps are an abstraction of the real world and as such only approximate reality. Each layer of orthos or LiDAR data comprises dozens, if not millions, of measurements about location. Like all measurements, uncertainty is certain. Ortho and LiDAR base maps may not overlay well. They are often created for different purposes. Or the allowable error in each map is different. Important to any geospatial professional is quantifying the error. How close are the coordinates for a feature in the mapping to its actual place on earth? Which map is most accurate?”
