|
| The company airborne services cover everything from area selection, to data collection and modeling, using our advanced equipment and acquisition software. |
| EGI have completed a number of projects in a more cost-effective way of survey. Making and interpreting the data is our expertise whether it is small or larger surveys, we can always provide our client the best results possible for their project. A further major advantage gained from using our services is that all data collected is well documented including the details of specific instruments being used during each survey. |
