SEM Geomatics

SEM’s geomatics technicians capture, process, and analyze geospatial information using the latest in high-end tech including Geographic Information Systems (GIS) and high precision survey equipment. Whether it’s stockpile quantities or a land survey, we can deliver.

Geographic Information Systems (GIS)

We gather, manage, and analyze your geospatial information. Layers of information are used to visualize what you need to provide insights into your data.

Land Surveying

Our land surveying is used for construction and mining applications. We can create to-scale 3D models and topo maps of your property.

Bathymetric Surveying

Single-beam and multi-beam surveys of lake beds are a specialty of SEM. Bathymetry can provide better information for your port development or tailings deposits.

Aerial Surveying & Inspections

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 recurring flights can help with progress monitoring.

SEM also performs building and asset inspections with our rotary drones. Delivery includes a building 3D model, high res photos of damage, and an orthomosaic map if it’s a roof inspection.

Real-time data collection

Through the use of ESRI’s Survey123 and ArcGIS online software, SEM has developed several capabilities to collect, monitor, and quality check data, photos, and other information in real-time. Survey123 is used by field staff for many applications including collecting field data to completing company safety documentation. All this information is then stored in ArcGIS Online which can then be reviewed, managed, and quality checked by personnel in the office. This method of collecting data allows for a more streamlined data collection and quality control which SEM will avail of to produce high quality work for its clients.

Photogrammetry and LiDAR

We use aerial photogrammetry and LiDAR to map and scan client properties, buildings, and assets. These 3D and pointcloud outputs are useful for engineering, construction, and mine management.
