A simple method to compare spatial data distributions using normalized rasters

Geospatial analysis usually entails the comparison between different data sets; more often than not, the focus of such an analysis lies in the exploration of spatial correlation between ‘activities’. For example, assume data about the distribution of a certain industrial activity is available to a researcher who wants to determine the optimal location for a … More A simple method to compare spatial data distributions using normalized rasters

How to make a Heatmap

Heatmaps have grown to be the most popular tools when it comes to depicting “kernel density” of data. This article will provide a brief explanation of what the technique of “kernel density estimation” actually entails, then provide a walk-through leading to the creation of a complete modern heat-map, using QGIS software. First, what is a … More How to make a Heatmap

SWOT Analysis as a Basic Index in Spatial Development Projects

For any project with spatial implications, a SWOT analysis is a necessary first step. Given time and budget, an engineer can produce a myriad radically different solutions about the development of a plot of land. If allowed to brainstorm, he can conjure solutions that will cost twice or thrice the budget, solutions that are too taxing on the environment or incompatible with the local customs and necessities. Since brainstorming paves the way for actual project development, the team needs an efficient, rational way to cut the bulk and allow them to focus on the fewer solutions that are for example, within budget, eco-friendly, and most profitable. … More SWOT Analysis as a Basic Index in Spatial Development Projects
