To make an orthophoto map or model, RGB photos from a drone survey are corrected for image distortion and scale, and stitched together to create a highly-accurate orthomosaic map. Ground Control Points (GCPs) with known coordinates are also registered into the map during post-processing, in order to increase the georeferencing accuracy of the orthophoto to the real world. Each pixel contains 2D geo-information (X, Y) and the orthomosaic map can directly enable accurate measurements, such as horizontal distances and surface areas.
In 3D photogrammetry, RGB photos from drone survey are corrected for image distortion and scale, and stitched together to create a highly-accurate 3D map or model of the survey object. Each pixel contains 3D positioning information (X, Y, and Z) and the map can directly enable accurate measurements, such as horizontal and vertical distances, surface areas, and volumes.
3D maps can be further processed to generate DSMs, DTMs and Contour Maps, as well as many other other types of analytics.
A DSM is a 3D survey which includes everything in the survey area, including the natural and man-made features on the Earth’s surface. A DSM can be generated from photos (photogrammetry) as well as LIDAR data. Commonly required as a standard LIDAR survey data output, this will be a point cloud which includes everything that the LIDAR sensor scanned, including the top of buildings, tree canopy, powerlines, and other features of the land and surface structures. Very precise information about the height of those structures is provided.
A DSM is useful in 3D modeling for power transmission, pipeline management, telecommunications, urban planning and construction, and aviation. Because objects extrude from the Earth, and the size and volume of these objects can be measured using LIDAR data, a DSM is particularly useful in these cases.
A Contour Map is a vector data set composed of regularly spaced points and natural features such as ridges and breaklines. A Contour Map augments a DTM by including linear features of the bare-earth terrain.
DTMs are typically displayed as a map of breaklines that are set at certain distance and elevation parameters, following the natural contours of the land. The contour points are regularly-spaced and characterize the shape of the bare-earth terrain.
A DTM is a bare-earth version of the LIDAR data, with all the vegetation and surface features removed. A DTM is made by filtering the LIDAR data to remove all the trees and other types of natural vegetation, as well as all the artificial/built structures including power lines, buildings, towers, roads and bridges.
A bare-earth terrain model or DTM is particularly useful in hydrology and irrigation, soils and land morphology, land use planning and volumetric calculations about earthworks. DTM data from LIDAR is widely used in Mining, Oil and Gas, Construction and Infrastructure, Geothermal Energy, and Agriculture, among others.
