Name: Elevation contours - 2ft

Display Field: Contour

Type: Feature Layer

Geometry Type: esriGeometryPolyline

Description: These elevation products (bare earth DEM, hillshade, slope model, aspect model, and 2' contours) are all created from lidar collected over all of Los Alamos County and a significant portion of adjacent counties, roughly corresponding to the areas impacted by the Cerro Grande Fire. Total area of the lidar exceeds 400 sq. mi. The lidar data were processed to create a bare-earth digital elevation model with a 4-foot pixel size, using the New Mexico Central State Plane projection, NAD83 (FIPS 3002).From the DEM, all the other products were created using ArcGIS tools in version 10.1 as follows:Aspect was created using the aspect surface tool in ArcToolbox 10.1 in the Spatial Analyst toolbox using all default settings.Slope was created using the slope surface tool in ArcToolbox 10.1 in the Spatial Analyst toolbox using PERCENT_RISE as the measure of slope, all other settings were defaults.Hillshade was created using the hillshade surface tool in ArcToolbox 10.1 in the Spatial Analyst toolbox using a Z FACTOR OF 2, all other settings were defaults.2' Contours were created using the NRCS Countour Tools v10 from USDA (ftp://ftp.ftw.nrcs.usda.gov/NRCS_Contour_Tool/) using the "Create Index Contours From Original DEM" tool. The AOI was the entire AOI of the DEM using shapefile mask created for that purpose. The interval was 2' and the DEM elevation units were specified as feet.
