This DEM was created by coalescing .asc files from Xeos into a Raster Dataset within ArcGIS.
The purpose of this layer is to define the 1 foot contour intervals within Monroe County, New York, derived from 2017 LiDAR data. This layer is one of many contour layers used by the Monroe County Department of Environmental Services (DES).
This data was in State Plane NAD83 NY W US ft, vertical datum NAVD 88. Data products include: Classified point clouds, DEM's, and point and elevation data. Collection Dates: 4/2/2017, 4/3/2017, 4/8/2017, 4/13/2017-4/15/2017, 4/17/2017 |

|
This layer was created by the Monroe County Department of Environmental Services (DES). This layer was originally created in GIS in 2017 where raw first return ASCII files were converted into multipoint feature classes. Every contour and raster layer within Monroe County has since come from these multipoint feature classes (2017, Monroe County Department of Environmental Services, Rochester, NY). |
