Central Environmental Surveys offers services in the fields of nature conservation, environmental management and ecological computing. In particular, the consultancy has extensive experience of Habitat surveying, Management planning, Ecological audit and Air photograph rectification and analysis.
Key services include:
Plant communities surveyed and identified according to the National Vegetation Classification (UK), CORINE or Phase 1 habitat survey
Computerised vegetation analysis and mapping using the latest GIS software
Development Constraint Analysis and post development monitoring.
Ecological audit including LBAP audit
Air photo rectification
Orthorectification
This allows satellite and aerial photography or design schematics to be draped over three-dimensional maps, then viewed from various angles for landscape evaluations.
Example of a rectified air photograph
A square 1: 10,000 air photograph with edges of about 2.5km is stretched to conform to the topography by the orthorectification process. The central area is cropped and used as a tile in Arc View or other GIS. The resulting images are accurate to within 7 metres, allowing LBAP habitats to be mapped directly from the rectified coverage, whereas interpretation errors without orthorectification can exceed 150 metres.
