Stages in the mapping exercise:

Stage 1: Preliminary analysis of Google images of the area.

Stage 2: Mapping of Fieldvisit information through PRAs and GPS mapping.

Stage 3: Preparation of Google Earth Image with basic information required for mapping

Stage 4: Final Mapping using Powerpoint

Stage 1:

We start with a preliminary analysis of the study area in Google Earth. We zoom in to the area of 

interest and take a look at the area and try to understand the area as much as possible. Zooming

through the area is a technical requirement(images get stored in cache memory) if we are planning

to conduct the PRA exercise using a laptop without internet connection.

Zoom to Required Location(Mundra coast for example)

Stage 2:

Using a laptop, we show the Google earth images to the people from the local community and

identify the various features on the map. It is advisable to start the discussion by showing some

easily idetifiable location on Google Earth image of the area. For example, a river flowing near the

village. Once people become familiar with the images then the real discussion will start and people

will identify various locations with lot of excitement

To mark various locations on Google Earth, we use placemarks as shown belowStep 1 : Click here to

Step 1 : Click on Add Placemark icon

Step 2 : Move the placemark to the correct location

Step 3 : Enter the name of the location

Step 4 : Enter the details of the location

Step 5 : Click Ok

The placemarks can be added on the basis of GPS readings also, by entering the latitude-longitude

values.

Stage 3 :

After all the discussions with the community and marking of locations, we save the Google Earth

image as a picture (.jpg) file for further analysis and presentation.

Stage 4:

Now for final analysis, insert the image in a power point presentation.

We select properties of the Newly formed shape and select a suitable colour. We change the

transperancy settings so as to see the underlying image also along with the marked zone.
