My original field data projection was in kertau RSO. In order to match with the LiDAR data projection, i re-project my shapefile data to UTM 48N using the Project tool. It works well with the LiDAR data. When i load the two points between RSO and UTM in arcGIS, i saw that the point are distant between each other for about 100 meters and above. The question is, is arcgis doing the right job? See picture attached below, is this normal?
