Robust Cultural Heritage Constraints Mapping

Need GIS skills for taking on large scale projects? Impact GIS can help!

Best practice dictates that from the earliest stages of considering a development, environmental constraints should be fully integrated with the planning process.

With most data sources for archaeological, architectural and cultural heritage constraints now available online, GIS mapping has become an indispensable tool for constraints mapping and the entire impact assessment process.

The following is a brief outline of Impact GIS’s process for archaeological, architectural and cultural heritage constraints mapping. Continue reading “Robust Cultural Heritage Constraints Mapping”

The importance of light

The video below demonstrates the importance of light for identifying potential archaeological features. Flat light or overcast conditions, which limit shadows, make it extremely difficult to differentiate the small topographical changes that may be indicative of archaeological features.

In the video below a drone / UAV survey was undertaken to create a detailed 3D model or Digital Surface Model (DSM). The DSM, as a software construct of the 3D surface of the ground, can have its texture changed and can be lit from any angle providing the shadows that may otherwise be lacking.
