+===== Remove Header =====
+The CRS header can be removed from the Resource via the Dataset Properties Window. Unique upload situations may require OPC data to not have the CRS header.  Some situations include:
+  * Geospatial Alignments in iModels
+    * iModels with custom CRS
+    * Local Scan Data
+    * Scan data referenced and tied to custom iModel CRS
+    * No available CRS to assign local data
