Aerial Imagery

Aerial imagery (aerial photography) offers a bird's-eye view of the landscape. It captures detail about the Earth's surface, such as topography, vegetation, water bodies, infrastructure and human activities that often can’t be seen from ground-based or map-based observations alone (e.g. roofs with solar panels).

Aerial imagery is essential for monitoring changes over time, and a robust basis for 3D modelling too. It’s an indispensable tool for situational awareness, decision-making, and helping to satisfy legislative requirements for biodiversity, environmental impact and planning.

Emapsite licenses aerial imagery data from the leading providers in Great Britain, spanning the entire gamut of common aerial imagery resolution:

• 12.5cm - roof tiles / street furniture (urban and electric vehicle charging site planning; solar panel installation studies; ssset management - identifying equipment, signs etc.)

• 25cm - cars, building features (environmental impact assessments; property assessments; infrastructure planning and retail site analysis)

• 50cm - building types, road networks (habitat mapping; regional development/infrastructure planning)

• 1m - building footprints, agricultural fields (forestry/agriculture; urban sprawl analysis)

• 2m - general land cover, larger scale planning (regional economic development planning; national land use)
