Engaging In Raster Data Analysis Using UAS Data
Engaging In Raster Data Analysis Using UAS Data In a previous post we worked through some ESRI tutorials regarding raster data analysis. In this post, we will be engaging in raster data analysis using actual UAS data gathered over the course of a mine dredging operation. The data is called "Litchfielddredge" and was provided to us by our professor. The data was collected on three different dates and we were tasked with performing an aspect, slope, hillshade, and elevation analysis for each one and compare them. Before we get into the analysis, lets look at the two tools we are going to be using. Extract by Mask (A raster clip within Geospatial Analysis): The extraction tools allow you to extract a subset of cells from a raster by either the cells attributes or their spatial location. Extracting cells by specific locations required that you identify those locations through cell identified using a mask raster. Resample The resample function changes the raster pixel size. Repro...
