SSHCZO -- Digital Elevation Model (DEM), GIS/Map Data, Land Cover, LiDAR, Soil Survey -- Shale Hills -- (2010)

OVERVIEW

Description/Abstract

High-resolution Lidar data (average 10 points/m2 with 2-4 cm vertical accuracy) were collected for the Susquehanna Shale Hills CZO (Area = 169.80901 km2) during leaf-on (7/14/2010-7/16/2010) and full leaf-off (snow clear) (12/3/2010-12/9/2010). Data acquisition, ground-truthing, vegetation surveys and processing were funded and coordinated by NSF Award EAR-0922307 (PI. Qinghua Guo). Data was collected with the Gemini 06SEN/CON195 and digitizer 08DIG017 system installed on the Cessna 337 tail number N337P. Total points: 2,840,000,000 pts. Area: Area = 169 km2. Shot density: 13.54 points/m2. Survey report, with details about data processing: http://opentopo.sdsc.edu/metadata/2010_NCALM_CZO_Project_Report.pdf. All files are in ArcGRID format.

Shaver's Creek and Shale Hills watershed boundary DEM files contain 0.5 meter resolution DEM from LiDAR collected in February 2011. Grid cell dimension = 0.5 x 0.5 m, Projection = ' +proj=utm +zone=18 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs' (UTM 18N), Gaussian Filter with square 4 x 4 m smoothing window applied to data to produce DEM. Boundary Delineation Algorithms consisted of three steps: 1) Calculate Upslope Contributing Area of catchment with DEM using multiple algorithms; 2) Model channel network using the DEM and upslope contributing area map(s); 3) Input channel network and DEM into a basin delineation algorithm. These steps were performed in SAGA GIS, which uses same algoritms as in TauDEM (ArcMap extension).
