Raster Analyses

From raster analyses, I learned spatial analysis and modeling with raster data. I estimated the access costs for all points on a landscape, based on slope and distance to roads. You’ll then apply a threshold to this access cost.

I created a mosaic of the valley DEMs. Then I fixed the Shasta DEM and produced a hillshades corrected elevation map. Then I created the second map, a cost surface with an applied threshold, and some of the intermediate data used for the cost surface.

Final project(UAS data mapping mission)

Image
Required for the mission:         Mobile device with supporting mission planning software          A UAS Platform/Sensor of your choice I was asked to fly an assigned mission plot at PWA with this parameter. Altitude: 122m Lateral and Frontal Overlap: 80% Use the search function to find and open the Add Z Information (3D Analyst Tools) tool. This tool calculates properties of 3D shapes and appends the result to the attribute table of the input feature class. In this step, you will calculate the length of each sight line. Set the following parameters: Input Features: LOS_Lines Output Property: 3-Dimensional Length      The purpose of this project is to conduct a UAV mission to collect aerial imagery and data for a specific area at PWA(Purdue wildlife Area). The mission area has been assigned and the goal was to fly the assigned mission area while ensuring that the flight boundaries are slightly larger than the assigned area to ensure complete coverage. The Pilot(Jinwook paek) and my v

Volumetric analysis with UAS Data

Image
In a previous lab, I completed some ESRI tutorials regarding raster data analysis. This time, I engaged in raster data analysis using UAS data gathered over the course of a mine dredging operation. I needed to draw upon what I've learned in the ESRI tutorials so far. ·        Extract by mask This tool extracts the cells of a raster that correspond to the areas defined by a mask. The mask is typically a raster dataset where cells with a certain value represent the areas I want to extract. ·          Resample Resampling is the process of changing the resolution of a raster dataset. ·          Surface volume The Surface Volume tool calculates the volume between two surfaces. I began on the 4 th of July to where the mine operation tells of the dredging to take place, and for me to establish a base dataset to know how much material was added. They are also concerned about slope failure and low lying flat areas where water will collect. Because the area flown is pretty large,

Performing Line of Sight Analysis by Esri Use the search function to find and open the Construct Sight Lines (3D Analyst Tools) tool. In the Geoprocessing pane, set the following parameters: Observer Points: Observers Target Features: ParadeRoute Output: ..\EsriTraining\ProLineSight\MyData\MyData.gdb\ SightLines Observer Height Field: SHAPE.Z Target Height Field: SHAPE.Z Sampling Distance:  30 Use the search function to find and open the Line Of Sight (3D Analyst Tools) tool. Set the following parameters: Input Surface: Elevation Input Line Features: SightLines Input Features: Buildings_subset Output Feature Class: ..\EsriTraining\ProLineSight\MyData\MyData.gdb\ LOS_Lines Use the search function to find and open the Add Z Information (3D Analyst Tools) tool.
