Aerial & 3D Data
Aerial Mapping & Orthomosaics
Rectified aerial imagery: distortion-free, georeferenced and true to a national grid. A single mapped image of a whole site that you can measure from, import into your software and use as a drawing base.
Typical accuracy · Typically 2 to 3 pixels ground sample distance, controlled to within a few pixels.
When you need it
- →You need a true-to-scale image base of a site or an estate.
- →A boundary or an extent needs to be shown on imagery.
- →Field teams need a mapped base to work from on a tablet.
- →You need a record of site condition at a specific date.
What you get
- Georeferenced orthomosaic in GeoTIFF, JPG or similar
- Ground sample distance and stated accuracy
- Alternative colour or band combinations on request

Questions we get asked
How current does the imagery need to be?
As current as you need it to be. For a condition record, older imagery is fine and cheaper. For an active site or a dispute, it should be recent enough to be relevant.
Often needed alongside
