Fascinating Info I Guess You By no means Knew About "http://event-phot…

0.6 m DEM derived from the 2014 LiDAR flight. Euclidian distance from streams and storm water lines. Euclidian distance from catch basins. Distribution of slopes in the study area. Distribution of ponding areas within the study area. Flood elevation during Sandy within the study area based on the USGS sea surge map. A catch basin layer was assembled from multiple data sources: handheld Trimble Geo XH GPS with sub-meter horizontal accuracy, digitized from 2009 aerial imagery with 15 cm pixel resolution, and engineering drawings. The Euclidean Distance Tool was again used to calculate the distance of each pixel to its surrounding catch basins. A slope layer (0.6 m resolution) depicting the inclination between pixels of a raster surface in degrees was derived from the DEM. A ponding layer was introduced to account for the spill effect from depressed areas into nearby areas. The ponding layer was created by extracting all elevations 1.2 m (NAVD88) and below via the Extract by Attribute tool in ArcMap.

I love how you said you will not help and not responsible lmfao… Naturally, people don’t read instructions
