Map is the first need in the beginning of any project from small construction work to big mining and infrastructure project. These needs are conventionally met by either satellite imagery which is very inaccurate and obsolete. Also, via conventional surveys using ground equipment which takes days to deliver the final outputs. Our drones can produce sophisticated 2D maps. That enable you to fill in imaging gaps left by satellite mapping with up-to-date data. We currently provide services to construction, the oil & gas industry, landscape architects, surveyors to name a few.
Our team is specialized in large area mapping and we have completed large projects for different applications. However, using UAVs for such applications brings out a huge advantage in quality when compared to satellite imagery and in cost when compared to conventional aerial data using Manned Aircraft.
Photogrammetry as a science is among the earliest techniques of remote sensing. The word photogrammetry is the combination of three distinct Greek words ‘Photo’, ‘Gram’ and ‘metry’ which translated in English literally means, light, drawing and measurement respectively.
Fibrox3D offers a wide variety of photogrammetric services such as aerial photogrammetry and Digital Photogrammetric services to its clients worldwide. The aerial photogrammetry and digital photogrammetry services are obtained using aerial acquisition through digital ortho-photography.

Details od some of the services offerd are:
Aerial Triangulation :
Aerial Triangulation is the calculation of true ground co-ordinates and 3D coordinates for object elements that are used as the base reference in aerial photogrammetry and digital photogrammetry. It is the method of developing several unknown coordinate points from a minimum of five control points inside each aerial photogrammetry model to be able to obtain absolute orientation of the model. Aerial Triangulation is an essential part of many successful aerial photogrammetry and digital photogrammetry project.
Fibrox3D offers complete softcopy aerial triangulation services, providing highly accurate control for the map production. Digital images are uploaded into softcopy work stations. The airborne GPS coordinates and the ground survey control points are used to control the aerial triangulation solution.
Fibrox3D utilizes LPS, SSK, DATUM software’s to perform digital aerial triangulation computations and analysis. Depending upon the project requirement and volume, Fibrox3D chooses the software as per the client request to provide qualitative aerial triangulation.
LiDAR Data Processing :
Fibrox3D provides LiDAR data processing, a prominent technology of aerial photogrammetry and digital photogrammetry services for the generation of Digital Elevation Model (DEM), Digital Terrain Model (DTM) and Triangulated Inverse Network (TIN) and so on to provide highly accurate detail of earth’s surface.
The aerial photogrammetry and digital photogrammetry technique of LiDAR data processing is carried out on the acquired data after filtering noise and pre-processing activities using GPS survey for obtaining a referenced coordinate system with accurate elevation details. Once the pre-possessing of the data is complete, Fibrox3D technical staff uses Terra Scan and Terra Solid software for post processing of the LiDAR data. Fibrox3D has extensive experience aerial photogrammetry and digital photogrammetry services such as, generating the 3D models like DEM, DTM, TIN and other surface models as per the requirement.
Fibrox3D provides turn-key LiDAR data processing services in aircraft, digital orthophoto and various topographic mapping aspects, including:
- Preparation of Point clouds file (ground, canopy and intensity)
- Power line mapping, wire detection and transmission line survey
- Contour mapping and topographical maps
- Fusion with digital orthophoto or hyperspectral imagery
- 3D modeling and volumetric calculation
- Creation of vegetation cover and classification using LiDAR data processing
Digital Elevation Model :
Digital elevation model (DEM) is a medium of aerial photogrammetry and digital photogrammetry that is a representation of the Earth’s relief used for geospatial analysis and modeling. Elevation data are captured in the form of points with defined interval and the Break lines. Fibrox3D has vast experience in the creation of TIN Models and elevation models from the DEM data Contours.
Vector Mapping :
Vector mapping service is a branch of aerial photogrammetry and digital photogrammetry services provided at Fibrox3D. It is a representation of the earth surface features in 3D manner and used for geospatial analysis and modeling. Fibrox3D offers the preparation of map by extracting the vector or point information of railroads, buildings, hydrological features, vegetation, etc., as required by the user by different Symbols (trees, wells, poles, etc.,), Line types (rail, road, streams, etc.,) and regions (buildings, tanks, forest, etc.,) with unique ID.
Ortho Photo Generation :
Digital Orthophoto is a raster image generated by differentially rectifying scanned aerial photographs to compensate for distortions due to the altitude of the aircraft and the relief of the terrain. Digital Ortho photos combine the image characteristics of a photograph with geometric qualities of a map. The Ortho Photo generation.
3D Modeling :
Using 3D Modeling and virtual reality techniques, Fibrox3D is able to completely represent the client’s real world, bringing together all the relevant aspects of the 3D environment that you wish to model. Fibrox3D’s key functions include 3D visualization, 3D environment modeling, true 3D landscape reconstruction, visual reality and virtual reality integration, real time roaming with huge amounts of data.
