GeoLan 3D

GeoLan 3D (also styled GeoLan3D) is a North Yorkshire-based consultancy that provides remote sensing, digital documentation and visualisation services to the heritage industry. The company is led by remote sensing specialist Keith Challis and operates from North Yorkshire in the United Kingdom. Its work centres on the use of three-dimensional digital data to document, analyse and explore historic landscapes, buildings and cultural collections. The firm's core service is lidar (Light Detection and Ranging) analysis. Lidar provides high-resolution, landscape-scale three-dimensional terrain data and has the unique ability to map archaeology beneath the vegetation canopy. GeoLan 3D helps clients identify available lidar coverage for an area of interest, processes the data using a range of visualisation and analytical techniques, and supplies GIS-ready output, publication-quality graphics, analytical reports and HER-ready interpretations. Beyond lidar, the consultancy offers 3D visualisation and modelling, geoarchaeological analysis of lidar data, vegetation mapping and modelling, and woodland biomass modelling. It also works with third-party suppliers to help clients specify and commission bespoke lidar surveys. A second service line is airborne multispectral imaging, which captures light across the visible spectrum and infrared in multiple discrete wavebands. Usually at 1 m spatial resolution, multispectral imagery is particularly suited to geoarchaeological applications in coastal and river landscapes. GeoLan 3D also undertakes photogrammetric recording of buildings and artefacts, producing 3D models of heritage assets. The company maintains a presence on Sketchfab, where its digital photogrammetry models are published, and operates a Fab Store for 3D content. It offers bespoke services with published prices. GeoLan 3D positions itself at the intersection of archaeology, geospatial science and digital heritage, serving the heritage industry with specialist technical capabilities rather than mass-market products. Its clients are understood to include heritage organisations, archaeological units and cultural institutions requiring survey, analysis and visualisation of historic sites and collections. The company is privately held and does not appear to be listed on any public exchange.

GeoLan 3D is a North Yorkshire-based consultancy that emerged to serve the heritage industry with specialist remote sensing, digital documentation and visualisation capabilities. The company is led by remote sensing specialist Keith Challis, who is identified on the firm's website as the head of the consultancy. Its formation and early history are not documented in the available evidence, but its service model reflects the broader adoption of three-dimensional digital data in archaeology and heritage management. The consultancy's development is closely tied to the growing availability and use of lidar data in the United Kingdom. Lidar provides high-resolution, landscape-scale three-dimensional terrain data and can map archaeology beneath the vegetation canopy. Because lidar coverage is freely available for most of England, Wales and large parts of Scotland, the technology has revolutionised archaeological prospection and geoarchaeological studies. GeoLan 3D built its offering around helping clients identify available lidar for their areas of interest, process the data with a wide range of visualisation and analytical techniques, and deliver GIS-ready output, publication-quality graphics, analytical reports and HER-ready interpretations. Over time the company expanded its service lines beyond lidar processing. It added 3D visualisation and modelling, geoarchaeological analysis of lidar data, vegetation mapping and modelling, and woodland biomass modelling. It also began working with third-party suppliers to help clients specify and commission bespoke lidar surveys. A parallel capability in airborne multispectral imaging captures light across the visible spectrum and infrared in multiple discrete wavebands, usually at 1 m spatial resolution, and is particularly suited to geoarchaeological applications in coastal and river landscapes. A significant strand of GeoLan 3D's work is photogrammetry — the capture of 3D models of buildings and objects. The company publishes digital photogrammetry models on Sketchfab and operates a Fab Store for 3D content. This reflects its broader mission to use three-dimensional digital data to document, analyse and explore historic landscapes, buildings and cultural collections. The company offers bespoke services with published prices and remains a privately held consultancy based in North Yorkshire, United Kingdom.
