How do I find latitude and longitude for the location of my case study?

The easiest way to do this is to use the Google Earth desktop application (not weADAPT’s browser) and go to File | Tools | Options (Windows) or Google Earth | Preferences (Mac) and make sure 'Show lat/lon' is set to 'Decimal Degrees' not 'Degrees Minutes'. Then do a search for each place name.

For example, you search the name 'La Paz' in GE and when it finds it, click on the yellow pin at the top which will drop on the globe. If you right-click on the pin, the coordinates that come up in the window are the ones you want. The lat/lon need to be to at least 4 decimal places. If you do not have Google Earth installed you can also do this through your web browser in Google Maps. You can search for a place name (say a big town close by) and then navigate around the map until you identify the spot on the map where you want to locate your placemark. Place your mouse arrow on the spot you want, right click your mouse and select the "What's here?" option, this will put a green marker on your chosen location and in the search box it will display the coordinates of that location. You can then copy these across to your placemark you are creating.

You can also convert traditional Co-ordinate notation to decimal notation using various online resources. Search for "decimal co-ordinates conversion".
