gov.noaa.csc.maps:ny2000_cayuga Cayuga County New York Department of Planning and Economic Development 2000 Charleston, SC NOAA's Ocean Service, Coastal Services Center (CSC) http://www.csc.noaa.gov/lidar These data were collected in April of 2000 for the Cayuga County New York Department of Planning and Economic Development. Elevation points were sampled at densities necessary to support the generation of contours that meet or exceed United States National Map Accuracy Standards applicable to the map scales that County tax maps are published and for the following intervals of contour lines to be depicted: four feet for the entire county, two feet for the City of Auburn and adjacent area and two feet for six floodplain areas. This is a bare earth data set, the points, however, are classified as "Never Classified". There are points returned from water surfaces. Point spacing is approximately 5 m. Also, there are areas in the county where the data have been regularized, i.e. gridded points. To support the preparation of contour maps and to provide digital data for GIS-based topographic analyses. 200004 200004 Publication date Complete As needed -76.738775 -76.261512 43.417704 42.611301 ISO 19115 Topic Category Elevation None Bathymetry/Topography LiDAR Terrain Model Elevation Surface Laser None US New York Cayuga County Lake Ontario None Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.

Not provided Not provided Contract requirements for the horizontal accuracy of DTM for the City of Auburn and adjacent area was 0.5 m Root Mean Square Error (RMSE) and 1 m RMSE for all other areas of the county. Contract requirements for the vertical accuracy of the DTM was 0.15 m Root Mean Square Error (RMSE). Cayuga County New York Department of Planning and Economic Development 2000 First Model Auburn, New York Cayuga County New York Department of Planning and Economic Development DVD 200004 200004 Publication Date Ground Condition Unknown The LiDAR data were collected in April 2000 for Cayuga County Department of Planning and Economic Development by EagleScan/3Di LLC For the City of Auburn and adjacent areas, the data was acquired at an altitude of 1000m (3000 ft) Above Ground Level (AGL). For the remaining area of the county, the altitude was 2000m (6000 ft) AGL. 2000 The NOAA Coastal Services Center (CSC) received the files in ESRI shapefile format. The data were in New York State Plane coordinates, Central Zone, NAD 83, NAVD88 vertical datum and the vertical units of measure were feet. CSC performed the following processing to the data to make it available within Digital Coast: 1. The data were converted from ESRI Shapefile format to las format using LASEdit. 2. The data were converted from New York State Plane Central coordinates to geographic coordinates. 3. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid99. 4. The vertical unit of measure for the data was converted from feet to meters. 5. The LAS data were sorted by latitude and the headers were updated. 6. The data were filtered to remove outliers. 20081223 Department of Commerce (DOC), National Oceanic and Atmospheric Administration (NOAA), National Ocean Service (NOS), Coastal Services Center (CSC) Coastal Elevation Mapping (CEM) Project Scientist Mailing and physical address

Charleston SC 29405-2413 843-740-1200 tcm@csc.noaa.gov The NOAA National Geophysical Data Center (NGDC) received Lidar data files on external harddrive. The disk contains LiDAR data from the NOAA Coastal Services Center. This data is currently being served via LDART at http://www.csc.noaa.gov/ldart . This data can be used to re-populate the system. The data are provided on this disk in two forms, ascii x,y,z data and also in LAS format. LAS format is an industry standard for serving LiDAR data. The data are exclusively in geographic coordinates, however, the datums used vary. Most is NAD 83, however some is in ITRF. Vertical systems include both ellipsoid (ITRF and NAD 83) and NAVD 88. For NAVD 88 values, Geiod 03 is primarily used; however, data received in NAVD 88 prior to 2003 was processed using Geoid 99. 20060103 DOC/NOAA/NESDIS/NGDC > National Geophysical Data Center, NESDIS, NOAA, U.S. Department of Commerce Pamela Medley Mailing and Physical Address
