For the following tutorials please download these shapefiles from http://www.diva-gis.org/gdata:

  • United States Administrative areas (USA_adm.zip)
  • Andora Administrative areas (AND_adm.zip) (takes less storage space for free accounts)

In this exercise you will learn how to:

  1. Classify attributes based on their distinct or continuous values.
  2. Manage feature’s appearance settings.
  3. Manage labels.

Before setting classification and appearance settings you have to:

  1. Create new map: Home tab->Create new map.
  2. Upload layers to the cloud: File manager->Upload.
  3. Add layers to the map: Layer tab->Add layers.

For more info, see Tutorial 1. Upload, prepare and add data.
