Lab 4

GEOJSON Files

Lab description

In this lab i created a map in qgis in which i downloaded data for countries from admin and the timezones.I projected the data onto QGIS.I then simplified it with the pre intalled simplied geometries tools for both timezones and countries. I uploaded it to geoJSON and picked 3 cities that i found facinating and emebedded them into data using d3.js and inccoporated into my website.

This is interesting because it allows me to pick awesome cities that i would love to visit. This also allows for me to see the spacial difference between the place i have picked. i can see how far apart. This was also a realy introduction to Qgis and Geojson and all the exciting new maps i can now make.
