data show same projection - why then does my lidar not line up with shapefile data correctly
I am new to lidar/gis and have tried to read through past questions but I am still having problems lining up my data. I am first bringing in Lidar which is in State Plane according to its Layer Projection under Options. I tell GM to load all other data I bring in into same projection. I then load a shapefile which has the same state plane projection according to arcatalog - but they don't line up when I bring it in. I verify once I have the shapfile in GM that it's projection is the same but they are off. Clearly something is wrong. I am not sure what to attach to this thread to help anyone help me help me.
