Understanding Rural Settlements in Rwanda.
In 2008-2009 through an aerial photography mission the government of Rwanda had orthoimages covering the whole country with a spatial resolution of 25 cm and only visual spectral bands (blue, green and red).
While working on my Bachelor thesis using Arcmap I created 88 5x5 km grids avoiding cities and I digitalized every single house present in those grids to sum up to 172893 points.
In this project I am using those points and perform distance calculation vis a vis different population distribution factors such as roads, rivers, schools…
I will use 3 examples each representing one vector data type:
- Lakes for polygon
- Roads for line
- Hospitals for point
Rasterize the results to visualize the distribution and later displaying the percentage of houses found in a particular distance range. Which goes with understanding the advantage or risks attached with the proximity.
