 For example, reading a LAS file from SSD to write an OPC to SSD storage using Intel i7 processor and 4GB Memory will take 2 Seconds per Million points.  For example, reading a LAS file from SSD to write an OPC to SSD storage using Intel i7 processor and 4GB Memory will take 2 Seconds per Million points.

 +===== 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
 +
 +Clearing the Point Cloud header enables the OPC data to be placed within the local/custom CRS grid from these iModel(s). Take note, extra care, knowledge, and information is required for these geospatial alignments.  
 +
 +If the iModels requires this, the import Mapping Template can have the pointcloud.write.options.ini updated with:
 +  
 +   remove.crs.header true
