– Place a buffer zone of 1000m around a polygon feature layer- dam.
– Convert the buffer zone layer to KML format.
– Open the Buffer zone.kml in Google Earth Pro so as to assess the physical environment that falls inside the buffer zone layer.
The Table of Contents has four layers. The Layer the buffer will be placed around is the Dam layer.
To place a buffer around the Dam layer, the ArcToolBox is launched.
In the ArcToolBox, Click the Analysis Tools > Proximity > Buffer
The Buffer tool window opens. Our input features is the Dam. the buffer range is 1000m or 1km.
A buffer polygon layer is added to the Table of Contents. See in blue highlight. A buffer zone is placed around the Dam feature.
The Buffer zone is now created and placed around the Dam. In order to assess the physical environment that falls within the buffer zone, the buffer polygon file is converted to KML and opened in Google Earth Pro.
Conversion from Layer to KML format using ArcToolBox . Launch ArcToolBox Go To Conversion Tools > To KML > Layer To KML.
Fill in the details and ensure the box Clamped features to ground is checked. Click Ok and processing is done.
Launch Google Earth Pro (if you have Google Earth, try and download Google Earth Pro, it is now a freeware). Open the Buffer KML file.
The map of the physical area that would be affected by releasing the dam waters 900m-1000m around the dam can be produced for assessment.
