I linked some NERC regulations under LiDAR specifications. The NERC regulations are very vage on what is to be done to comply to the regulations using LiDAR. The transmission companies and engineering firms are approaching the compliance differently. The companies are looking at the LiDAR firms to get information on how to comply. It is clear that they perfer the helicopter approach or a very low altitude approach. Some are open to a fix winged approach but this can be limiting and may not provide the required information for NERC. Fixed Wing has it’s place in Transmission mapping. Comments and rebuttal welcome.

The following article is about a mobile mapping survey done when I was with The Sanborn Map Company. The analysis was done while at my current employer AeroMetric. Please click on the link below to read. It will also be run in Quality Digest with by premission of American Surveyor. There is a link to the PDF for a full version of the article at the location below.
I am going to be posting some information about the NERC regulations and Transmission mapping. Please feel free to comment and I will post information others have as well. Also, look for information on regulations on the side menus as well.
I received a comment about NDSM (Normialized Digital Surface Model). I looked it up and it is a representation of elevation objects on a flat surface. It is genrated by using the difference between the DSM and DTM. Anyone care to elaborate on this?
Keith Cunningham and Rob Merry will be holding a Day long LiDAR workshop at the 45th Annual Alaska Survey & Mapping Conference In Anchorage. This workshop will cover several phases of LiDAR and further explain DSM/DTM/DEM, Datums and Coordinate systems among other things. For more details please click on the link below
