AT319 Lab #6 Raster Analysis in GIS: ESRI Tutorials

Overview:

For class this week I engaged in a series of tutorials created by ESRI for ArcPro. These designed to several forms of raster data analysis. I learned how you can use DEMs, DTMs, or DSMs for various forms of analysis such as calculating slope and aspect. Also, I did some other tutorials that show how one can calculate line of sight and viewshed analysis using GIS. As I completed these tutorials, I thought of how I could apply what I learned to both working with UAS data and/or in mission planning with UAS. Or, how these forms of analysis could relate to aviation management and safety.

Deliverables:

• A screen shot with labeled caption upon completion of each subsection of the tutorial.

• The exported PNG of the final product with this report.

• The certificate of the courses at the end of each assignment.

Terrain Analysis using ArcGIS Pro Deliverables

Fig. 1: Set the appropriate analysis environment.

Fig. 2: Ran the slope spatial analysist tool and raised the transparency level of the sd_slope layer.

Fig. 3: Ran Aspect spatial analyst tool and raised the transparency level.

Fig. 4: Ran the Raster Calculator spatial analyst tool and wrote an expression to derive slope and aspect surfaces from an elevation surface and used all three surfaces to perform a binary suitability analysis.

Fig. 5: Results of creating a new hillshade raster function layer.

Fig. 6: Changed the color scheme of Im_elevation and combined the hillshade and elevation surfaces.

Fig. 7: Created contour lines and added visually appealing labels.

Fig. 8: Ran Viewshed tool to show areas that can be seen from a point in the middle of the reservoir.

Performing Viewshed using ArcGIS Pro Deliverables

Fig. 11: Added VSPro.gdb database to the catalog pane.

Fig. 12: Editing the property boundary symbology then added the rest of the geodatabase feature classes to the map.

Fig. 13: Added additional fields to the attribute table and inserted the required values for each new field.

Fig. 14: Results from running the viewshed (3D analyst tools) tool.

Fig. 15: Results from creating a raster function layer. Results show the area of the campground covered by more than two lights.

Fig. 16: Changed the height of the lights with OFFSETA field values set to 10.

Fig. 17: Ran a new raster function analysis with the new light height. The lighting is much more improved from the previous height.

Performing Line of Sight using ArcGIS Pro Deliverables

Fig. 19: Opened up project file and added folder connection.

Fig. 20: Results of the Construct Sight Lines tool.

Fig. 21: Results of the Line of Sight tool. Green lines showing unobstructed views of the parade, red lines means buildings are blocking the view.

Fig. 22: Shape Length field added to attribute as a result of running the Add Z Information tool.

Fig. 23: Results from selecting and deleting the obstructed views and views with a maximum visibility of 1,100 feet.

Fig. 24: Results after running the modelbuilder view.
