the viability of sources such as satellite, radar and hyperspectral data for recording sites and landscapeįind out about all of our records by visiting the online catalogue of Scotland’s historic environment.

More and more, we also use 3D models of the ground surface (derived from ALS) to help with this process. You can also look at subdivision activity, aerial imagery, and many other features for unincorporated communities, or areas outside a city in Los Angeles County.Large amounts of data may be transmitted while using these sites. Our aerial mapping programme draws on existing aerial images and the results of reconnaissance to create interpreted maps that add to our knowledge of archaeological sites and landscapes. The following GIS apps let you interact with GIS information so you can view and research land use and zoning information. Searching lowland areas from the sky for buried sites that show as cropmarks has led to more than 9,000 such sites being recorded to date. adds some 4,000 to 6,000 photos to a collection of more than 166,000 aerial images of all aspects of Scotland’s landscapeĪerial reconnaissance to discover previously unknown sites is especially important.completes more than 100 hours of flying.In an average year, our aerial survey team: buildings, public trees, curbs and gutters, manholes. Increasingly, it also makes use of airborne laser scanning (ALS) – also known as LiDAR – data to understand the past and to aid conservation, planning and research. Digital Aerial Survey (DAS) maps illustrate surface features present in an aerial photograph (e.g. analysis of existing aerial photographs.record ancient monuments, buildings, urban areas and landscapes.An aerial view is a very effective way to understand and record Scotland’s historic environment.
