Name: Protected Slope Area

Display Field: SHAPE.STArea()

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Polygons cover any point on the island where there exists another point within a 40 foot radius that has an elevation difference of more than 12 feet .Steps used to create feature class:1. Create grid of points, 4 foot on center, covering the entire island (approx 11 million records)2. Join elevation data to points from surface (2016 Geoterra Lidar)3. Create grid of 200 foot squares, each buffered 40 feet for overlap. (The script was failing when trying to process the entire island- broke up into smaller squares to be considered one at a time.)4. Run script in project folder, which selects a point, evaluates it against every point within 40 feet, and returns "1" if high slope condition is met, or "0" if not. (Script currently located in M:/ArcMap Documents/DSG/ForHolly/2019 Tree Slope Permit)5. Buffer "1" points, merge and smooth until it looks good (we weren't going for extreme accuracy)
