Aerial Triangulation (AT)

Aerial Triangulation represents the mathematical process of establishing precise and accurate relationships between the individual image coordinate systems and a defined datum and projection (ground).
The main objective of aerial triangulation is to produce from ground control, sufficient points in the photogrammetric models to ensure that each model can be oriented accurately as required for stereo compilation in either orthophoto or line mapping.

Digital Elevation Models (DEMs) (Mass Points)

GWORLD derives elevation models to support flood mapping, ortho generation, 3D simulation, and more. We develop models using a variety of techniques including traditional photogrammetric techniques, LiDAR, and through autocorrelation of digital aerial imagery.

Digital Terrain Models (DTMs)

Today's GIS user is relying more and more on the use of 3D models and visualization. Once limited in scope to video games and Hollywood effects, 3D environments have become part of the evolution of GIS, allowing for analysis in x, y, and z. From property appraisal specialists to the modern day war fighter, the need for a highly detailed information in 3D is evident.
GWORLD is involved in the development and deployment of terrain models to support 3D analysis. Surfaces derived from LiDAR , photogrammetric techniques, and auto correlated surfaces, provide a framework for which a "skin" of realistic imagery is applied, creating a lifelike 3D scene.

Planimetric Mapping

GWORLD captures all planimetric features in a 3D environment, maintaining x, y, and z values for each individual point, line, and polygon. This enables customers to derive 3-D models of such items as road networks, buildings, utility features, and more.
We specialize in capturing natural and manmade features for comprehensive GIS solutions or for individual projects. Our techniques and detailed project management assure consistent results and accurate deliverables.

Topographic mapping

GWORLD compilers develop topographic data in a softcopy environment; the workflow designed so that edge-matching data results in a seamless project wide topographic representation.

Contour Generation

Giant orange pedal boats have been spotted at various beaches. In this report we tell you some ridiculous precautions to take.
