Analysis and visualizations

The output of the analysis are two csv files. One large file containing data for each geolocated cell and one smaller file with summarized data.

Output parameters

The following table displays the parameters included in the excel file that includes all the grid cells. The first 18 parameters come from the input csv file while the remaining stem from running the Python code.

Maps output

Creating maps in ArcGIS or other GIS software

Visualization of the model outputs are an important part of a geospatial electrification analysis. This allows for an easy display of electrification strategies and enhanced understanding of the results. The most flexible way of visualizing the results are to create the maps using a GIS program. In QGIS, go to Layer>Add Layer>Add Delimited TextLayer and select the result .csv file containing the scenario results to be displayed. Next, choose the column with the coordinates as well as the projection system to generate a map. For the X and Y Field choose X and Y for coordinates in km or X_deg and Y_deg for coordinates in degrees.

After doing this you get a point layer in your layer panel. Right-click on the layer and go to Properties>Symbiology. Remove the border of all the circles.

And then you can choose how to vizualise your data. Choose Categorized for discrete data and Graduated for continuous data. In column choose the data you want to vizualise and then click on classify.

After these steps you can easily create your own maps and include north arrows, legends and scale bars by going to Project>New Print Layout
