Projection is a method to represent 3D data into 2D. It plays a important role in GIS. A map projection is termed as Coordinate Reference System (CRS) and QGIS allows users to define custom CRS. So in this article QGIS Tutorial – Vector Analysis – Create New Projection we will get familiar with creating your own CRS as per need.

QGIS Tutorial – Vector Analysis – Create New Projection
- Start a new map >> upload a vector file using add layer in layer in menu bar.
- Go to Setting menu bar >> select Custom Projections
- Tap on Add new CRS button for new projection creation shown in below image.
In the Name field fill Van der Grinten I and in the Parameters fill this string
+proj=vandg +lon_0=0 +x_0=0 +y_0=0 +R_A +a=6371000 +b=6371000 +units=m +no_defs
And in the last click on OK
- Now click on CRS button in the status bar at the bottom right of QGIS button.
- Filter the user defined projection, Select and click on OK button.
Here is the map with new projection. It looks interesting then earlier one.
