This new map of Southern New Jersey is a lower resolution version of my LIDAR in the Pines HD, converted to Garmin's traditional map format. The source data for the map is 1/9 arc-second LIDAR imagery from the USGS 3D Elevation Program (3DEP). LIDAR (LIght Detection And Ranging) is a system for laser-scanning the surface of the earth to produce a very accurate Digital Elevation Model (DEM) of the terrain. The raw data can be processed in different ways to create maps of 3d terrain. The custom shading used for this map is specially tuned to the flat South Jersey terrain, revealing subtle details that are normally lost in other maps of the region.
Since it's not as detailed, this map is only 400 MB while LIDAR in the Pines HD is a 15 GB download. The map also has simple one-click installation for Garmin Basecamp, with separate versions for Windows and the Macintosh. A third version provides the compiled .img file for easy drag and drop installation on a GPS device, avoiding the Garmin MapInstall problems that have been extensively discussed in the GPSFileDepot forums. Each version has its own all-new illustrated tutorial, written for beginners.
LIDAR in the Pines SD is the first in a series of maps based on my new digital model that covers South Jersey with a grid of over 60 million 48ft x 48ft (15m x 15m) cells. This model can represent any kind of map imagery by just changing the colors of the grid cells. And each cell can also contain additional data, such as the spot elevations in this map. The resulting dataset is easily converted to Garmin .img files.
The unique way the map was created places a heavy demand on a GPS device however. It has been road-tested extensively on a Garmin DriveSmart 61, but it did not work properly on an older unit. Technically, it is compatible with all Garmin devices, however it is only recommended for the newest automotive models. You'll need to do your own testing to see if it works on your device.
But you'll still find it useful on the computer even if you don't have a compatible GPS unit. Basecamp has no problems with the map and you can zoom and drag the map around smoothly. As you move the mouse pointer around, the elevation of each grid cell is displayed. The roads, streams and elevations are also displayed on top of your Garmin BirdsEye imagery if enabled. And this map is fully compatible with Garmin's older Mapsource software.
LIDAR in the Pines SD should be of special interest to Garmin users who are reluctant to adopt the Mobile Atlas Creator software used for the other maps on my website. With a quick download and a few mouse clicks you can have real LIDAR imagery in Basecamp!
