Tutorial big data analysis: Weather changes in the Carpathian-Basin from 1900 to 2014 – Part 5/9
Data visualization – GIS, map based using Kartograph – Subsection 1/2
For the showcase purposes, I have used this Kartograph example to show bubbles with different colors and radius based on the yearly temperature and precipitation data (two datasets are in two different directories / diagrams)
Tutorial 1 on animated symbols dependent on the values of the dataset
and Tutorial 2 for in-built tooltips
- Get a map of our experiment
- Get the data to be shown for our experiment in Kartograph’s example parser’s format
- Show the map in a web browser
Kartograph / generating the map
I’ve installed the tool using this guide.
Cropped a map of central Europe from the map with the Python toolset using the following config file, world.json:
Data [numbers] are LAT and LON coordinates for the Carpathian Basin resulting from Google Maps – bottom left and top right coordinates of the bounding box.
For Kartograph to generate the interactive map: run the following command getting world.json as input and map.svg as output – in Bash shell:
So we have a world.svg file as an output that Kartograph JS can show.
