Add Vector Layer dialog-box opens.


Select File as Source type.


System as Encoding .



Click on browse.


Locate the folder ne_10m_admin_0_countries.


Under Source heading, click on Browse button.


Navigate to the admin countries folder,

downloaded from the natural earth data website.



From the folder, select the file, ne_10m_populated_countries.shp


Click Open


From the contents of the folder, select the file with .shp extension.


Click on Open button.

Click Open in, Add vector layer dialog-box.


Point to themap on canvas.

In the Add vector layer dialog-box, click on Open button.


A world map opens on the canvas.

I will save it on the desktop.


Click on Save button.


The map will be saved as Map-1.qgs on the desktop.

Slide Number 9

Spatial Data - Raster Data

About Raster Data.


  • Continuous features that exist spatially betwen observations is Raster Data.
  • Raster data is made up of cells in row and column format.


Cursor on slide Let's download raster dataset from Bhuvan website.
Slide Number 10

Bhuvan Website Link


http://bhuvan.nrsc.gov.in/data/download/index.php
