CAD Mapping Aerial Surveyors


Photogrammetric Digital Surface and Terrain Modelling	Professional Ground Surveying	LiDAR Data Processing	Orthophoto Creation	Photogrammetric Detail Mapping	Geographic Information System Data Management
We create Digital Surface Models (DSM) at any client specified point density utilising per-pixel correlation technology techniques. The surface model points will then be filtered and edited in stereo to true ground level. Break lines will be captured at all changes of slope and merged with the ground point data, this data set is a Digital Terrain Model (DTM) from which a triangulated surface can be created for contour generation, engineering design and volumetric calculations.	All CAD Mapping digital line mapping (Vector Mapping) is captured using Photogrammetric methods on a Stereo capable digital photogrammetric workstation. This ensures that all detail is captured in their true position in a 3D environment. The detail is captured to the client-specified formats and layer structures. Our detail plans conform with TMH11 Engineering standards as well as with 4th Schedule Mines and Works standards.	We utilise a state of the art Leica ALS70 and ALS50- Plus to acquire topographical and multi-return signal intensity data from numerous airborne platforms. We seamlessly integrate LiDAR data with other datasets to generate complex mapping products, advanced 3D models and renderings of structures.	We use differential rectification for image correction methods to correct images to true orthogonal projection. All our orthophoto positioning are derived through a photogrammetric aerial triangulation process from photography with a minimum of 60% forward overlap and 30% side overlap to retain a high geometric accuracy.	We capture digital line mapping (vector mapping) using photogrammetric methods on a stereo capable digital photogrammetric workstation. This ensures that all detail is captured in their true position in a 3D environment.	We specialise in GIS data capturing, data management and mobile GIS solutions. GIS data is compiled through data capturing in field with a GPS device or is captured on geo-referenced image data or photogrammetric procedures. Intelligence is added as attributes to captured data complying with client specific geodatabase demands and rules. All our data is topologically cleaned and correct to assist in accurate data analysis modelling.
