A large aspect of most project reporting at SEM includes the generation of maps to aid in project visualization. SEM has on staff several GIS personnel capable of mapping using ArcGIS software.


Most of SEM's work with remote sensing comes from our aerial surveys using UAVs. Our fleet of UAVs can provide orthomosaic imagery with much higher resolution then traditional satellite based imagery. This imagery can allow clients to get a better understanding of their project area and reoccuring flights can help with progress monitoring.


Using advanced software SEM has the capability to spatially analyse large data sets for various project needs. This includes many functions such as 3D modelling and analysis, ecological land classification, and image classification.

Real time Spatial data collection and monitoring

Through the use of ArcGIS online, SEM has the capability to setup in field data collection from iPads for real-time monitoring. This is particularly useful for organizing and maintaining consistency for collected field data but also it allows managers to monitor progress from their desktop.

Bathymetry mapping

SEM has performed bathymetric studies for clients in the past. In 2016 SEM staff completed a singlebeam cross-sectional survey of the Exploits River from Red Indian Lake to Red Cliff as well as surveys of Badger Brook and Badger Lakes.
