Drones & Remote Sensing

Our GIS experts have experience in spatial analysis, data management and mapping, capable of performing different studies integrating vectorial, raster and database information.

With Remote Sensing techniques we can perform change detection and monitoring studies, such as new building detection, land use/land cover classification, spatial database update, etc. For these purposes, we integrate GIS and image processing procedures that allow us to extract the maximum quantity of information from the geospatial data (multispectral satellite and aerial imagery, drone data, 3D data and database) and to provide a high quality product to our clients.

Drone data on demand

Results

  • Accurate results
  • "As built" data or CAD and BIM
  • Data delivery in days
    • Drone mobilization in less than a day
    • Flights generally less than an hour

Studies

  • Project design / Project monitoring
  • Site monitoring / Change detection / Repeat survey
  • Volume calculation
  • Mapping
  • Data update / Reconnaissance

In agreement with recognized standards.


Volume calculation

  • Check contractor estimates of excavation volumes removed
  • Ensure proper survey dimensions
  • Gather data before construction begins which can not be reversed
  • Drone flight not to interfere with operations (less than one hour flight)

BIM Modelling

  • Survey coordinates in line with Architect's drawings
  • Accurate “As Is” Drone pictures allow assessment of suitability for structure
  • Format interoperability
  • Integrate Drone data directly with building drawing to ensure exact match
