Data Processing

2D ORTHOPHOTO

ORTHORECTIFIED MAPS AND MODELS

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.

Data Processing

3D SURVEY & MAPPING

PHOTOGRAMMETRY MAPS AND MODELS

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.

DIGITAL SURFACE MODEL

DSM: LIDAR SURVEY AND MAPPING DELIVERABLES

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.

DIGITAL TERRAIN MODEL (DTM)

DTM: LIDAR SURVEY AND MAPPING DELIVERABLES

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.

CONTOUR MAP

CONTOUR MAP: LIDAR SURVEY AND MAPPING DELIVERABLES

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.

STOCKPILES & VOLUMETRIC CALCULATION

RAPID ACCURATE VOLUMETRIC MEASUREMENT FROM DRONE SURVEYS

Measuring material volumes in a 3D area or void space is an essential function in mining and quarrying. Halo Robotics can provide calculated volumes of any stockpile, land, or earthwork area. Just send us your raw data, and we can quickly turn around accurate site surveys, including volumetric calculations on specified areas and stockpiles to support operations as needed.

VEGETATION ENCROACHMENT & CORRIDOR ROW MANAGEMENT

SURVEY DELIVERABLES FOR PIPELINE AND POWER TRANSMISSION CORRIDORS

Pipeline and Power Transmission corridors require constant supervision, to prevent the encroachment of vegetation into the assets – which can cause major problems. Using a DSM survey which includes all vegetation and structures which extrude from the Earth, it is possible to use algorithms to map the location and quantity of vegetation that is encroaching beyond certain tolerance limits along a corridor. Monitoring vegetation encroachment in this way is essential for power transmission line maintenance, to ensure that plants and trees do not grow into the lines and cause fires and power supply disruptions.

MULTISPECTRAL

MULTISPECTRAL IMAGERY ANALYSIS FOR CROP HEALTH & AGRICULTURAL RESEARCH

Multispectral imagery is an essential type of data for crop health analysis in order to detect issues and increase yield. Halo is the Indonesia leader in multispectral imagery analysis and our specialists have unique experience with multispectral survey post-processing and analytics for wide-ranging crop types and research objectives.

Multispectral cameras capture Red, Green, Blue, and Near Infrared light (“NIR”) which is also reflected and absorbed by plants. Analytic filters of light (“Indexes”) applied to multispectral drone surveys are very powerful to support detection and diagnosis of issues which affect crop health, including pests, fungus, disease, irrigation, and nutrient deficiencies. Using multispectral imagery analysis, it is also possible to accurately evaluate the impact of interventions.

Custom Indexes can also be generated in order to help clients identify specific spectral bands associated with specific issues or research objectives, in order to save a “custom filter” which can be applied to larger data sets and future surveys.
