Field officers of BBNL are the supervisors who will further create contractor accounts for respective areas. Username/ passwords for the BBNL field officers has already been sent to them by SMS. The system is configured to send username/ password to contractors by SMS as and when their accounts are created. Please check this. Once lat/lons have been captured with the mobile application, the supervisor can login to the web application and authenticate the points collected. The routes will then be drawn through the points and details including length of routes will be available on the screen.
