Digimap is a web mapping and online data delivery service developed by the EDINA national data centre for UK academia. It offers a range of on-line mapping and data download facilities which provide maps and spatial data from Ordnance Survey, British Geological Survey, Landmark Information Group and OceanWise Ltd Ltd., (marine mapping data and charts from the UK Hydrographic Office ...
A national lidar dataset refers to a high-resolution lidar dataset comprising most—and ideally all—of a nation's terrain. Datasets of this type typically meet specified quality standards and are publicly available for free (or at nominal cost) in one or more uniform formats from government or academic sources.
Topographic maps are possible because of the Inertial Measuring Unit and Global Positioning System. [3] Furthermore, it is a technology that can carry out studies on a steep slope and rock-cliffs. [4] Accurately measured data is necessary for the LiDAR data to be geo-referenced such as

Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.
Nevertheless, Storm Herminia battered the UK. The forecaster recorded 84mph gusts of wind in the Isle of Wight, while 59.4mm of rainfall was recorded in Seathwaite, Cumbria.
Mobile mapping is the process of collecting geospatial data from a mobile vehicle, [1] typically fitted with a range of GNSS, photographic, radar, laser, LiDAR or any number of remote sensing systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform. [2]
Multiple scans, from different directions are usually helpful to obtain information about all sides of the subject. These scans have to be brought into a common reference system, a process that is usually called alignment or registration, and then merged to create a complete 3D model. This whole process, going from the single range map to the ...
