Spatial Analysis

The collection of geographic data (Geomatics) and the organization of that data, Geographic Information Systems (GIS) is an integral part of understanding the natural environment and natural resource projects. If you are in the planning stages of a restoration or development project, we organize and provide existing GIS data to understand the historical context of an area. Using online GIS databases (e.g. dataBC), historical aerial photographs or old paper maps, we can help you understand how an ecosystem has come to its current state.

We improve upon existing datasets by collecting accurate and precise spatial data, tailored to the needs of each project. Using a variety of technologies including on the ground GNSS surveys, LiDAR, total station surveys, and drone mapping, we collect spatial data to show what the area looks like in the current moment.  We use these tools to survey & classify ecological features at a variety of spatial scales – anything from the path and morphology of a small stream, to land cover and vegetation communities in a large estuary, to physical and biological classification of an entire coastline. This allows us to provide you with up-to-date data describing the geography and biology of an area. From this data we can perform additional analysis, such as characterizing current habitat suitability and species distribution for a species of interest, creating models to estimate the impact of a development project, or modeling the potential impact of a natural disturbance such as sea level rise.

Data Collection

  • GNSS (GPS) positioning of features, environmental gradients
  • Drone orthoimagery collection to see a landscape aerial view
  • Total station surveys
  • Bathymetric and water column data with our SONAR, ADCP and ROV

Data Analysis and Visualization

  • Terrain mapping and modeling (3D models, hillshades, aspect, insolation)
  • Orthomosaics for up-to-date basemaps
  • Cartography and map presentation
  • Landscape change detection
  • As-built surveys of construction or restoration sites
  • Environmental impact footprint mapping

Reporting

  • Detailed report of project scope, rationale, actions and results
  • Topographic survey drawings
  • Spatial database
  • Aerial/underwater images for context
