Methods in Spatial Analysis

Network Analysis of Salzburg

The Network Analysis Tools of ArcGIS Online and ArcGIS Pro are incredibly versatile tools that make some complicated mathematical problems easily solvable with just a few clicks.

On this report, I explore several of them in the context of Tourist Attractions in the Austrian City of Salzburg.

Catchment Basin Analysis of the Thumersbach River

Continuing the ongoing exploration of ArcGIS Pro Tools, the focus this time was on Digital Elevation Models (DEMs) and their relation with river catchment basins. The study area was the basin of the Thumersbach River, and I explored the elevation and its derivatives, with special focus on the slope. In the end, I compared the results for lower-resolution DEMs.

The Towers’ Conundrum: a Visual Impact Analysis

For the last of a trio of assignments exploring ArcGIS Pro Tools, I performed a visual impact analysis of a trio of towers planned in the city Porto. I began by calculating the Lines of Sight from the towers to several viewpoints spread throughout the region using a 50cm Digital Surface Model. Afterwards, I performed a View-Shed Analysis using the same Model. Finally, I combined the Digital Surface Model with a Digital Terrain Model and focused on parks and beaches as my metric to assess wether or not the towers’ height was indeed problematic.
