  Volumetric's We are going to calculate the volume of an aggregate pile that was created during a dredging operation, then we will be utilizing several new tools within ArcPro. We will be working with two different datasets, the first is Wolfpaving and the second is Litchfield which we've already used in a previous  post.  The three main tools that were going to use is: Extract by Mask: Extracts the cells of a raster that corresponds to the areas defined by a mask. If the mask is a feature, it will be converted to a raster internally using cell size and cell alignment from the input raster. For Wolf Creek, I used the dsm input with the Pile1 cut out I made over the pile. Resample: Changes the spatial resolution of a raster dataset and set rules for aggregating or interpolating values across the new pixel size. The cell change can be changed, but the extent of the raster dataset will remain the same. Surface Volume: Calculates the area and volume if the region b...

 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...

 Raster Analysis in ESRI Tutorials with ArcGIS Pro     We are going to engage in a series of tutorials created by ESRI for ArcPro. These are designed to serve several forms of raster data analysis. We will be seeing how you can use DEMs, DTMs, or DSMs for various forms of analysis such as calculating slope and aspect. Then we will do some other tutorials that show how one can calculate line of sight and viewshed analysis. As we complete these tutorials, it's important to think of how what were doing could apply to both working with UAS data and in mission planning with UAS. Or even how these forms of analysis could relate to aviation management and safety. We are going to engage in three different ESRI tutorials. Terrain Analysis using ArcGIS Pro:      When you are analyzing a mountain, an elevation surface is useful for answering the question, "How high?" But what if you want to know "how steep?" or "facing which direction?" What if you want...
