Below is a map that will allow you to download a .zip file for each of the corresponding tiles on the map. Each tile will display the available data, bare earth or first return, when the mouse is placed over it. Each zip file contains an edited LIDAR DEM GeoTIFF, hillshade grid, contour shapefile, and tile extent shapefile for a specific map tile. The zip files are named according to the UTM coordinates of their upper-left corner (in thousands). Each GIS layer has an accompanying XML file that holds the metadata.
The file named merge.zip contains a merged LIDAR DEM GeoTIF and contour shapefile that represents all 35 tiles included in this dataset. Use the links below to help navigate to the correct zip file.
There is also a zip file named shapefiles.zip. This contains all the vector data that was used while creating the PDF maps. These layers include the state of New York coastline, boundary of Fire Island National Seashore, island boundaries within Fire Island National Seashore, and LIDAR tile centroids.
All files are consistent with the UTM Zone 17 N Coordinate System, NAD83 Datum, and GRS80 Spheroid.
