Geocoding is the process of transforming a description of a location -such as a pair of coordinates, an address, or a name of a place- to a location on the earth's surface. This is particularly useful when you want to prepare the 3D model in Google Earth or obtain satellite image for a site. Both these features require geographical coordinates (i.e. latitude and longitude). VisLog uses Google server for geocoding.


You can start geocoding by entering the approximate location of the site. By pressing the "Start Geocoding" button, the following steps will be taken by the program:


  1. The approximate address will be used to obtain the UTM zone of the site (e.g. Vancouver, Canada is located in zone U10),
  2. Using UTM zone, the Easting and Northing coordinates of the boreholes will be used to obtain latitude and longitude of each borehole location,
  3. The bounding latitude and longitude coordinates will be passed to Google server to obtain the satellite image of the site (this is approximate). You can open the satellite image by clicking on <Satellite Image> link.

 


  In order to use geocoding function, you need exact UTM coordinates of the boreholes.
