HiRes1 airborne geophysical data WMS

BGS Technologies — Web map services

High-resolution, airborne magnetic, radiometric, VLF survey data (over the north Midlands of England into the Welsh Borderland) is provided as a web map service (WMS). Survey flying for the collaborative BGS and World Geoscience Corporation Ltd (WGC) high-resolution geophysical and environmental survey was completed in early September 1998. The data comprises multichannel gamma ray spectrometer, magnetometer and dual frequency VLF-EM.

Flight-line spacing was 400 m with tie lines at 1200 m. The total area surveyed is some 14 000 km2. Flight-line orientations are west – east over the western survey area and south-west – north-east over the eastern area. Ground clearance was maintained at 90 m in rural areas, increasing to about 240 m in built-up zones.

The service supports the British National Grid and lat/long WGS84 coordinate systems and the data is visible when zoomed in between 1:100 000 and 1:25 000 scale.
