Gaiamatics Solutions Inc. | ObliqueMapper: Tour

By: Gaiamatics Solutions  09-12-2011

ObliqueMapper was developed as a GPS based mapping tool. It can be used for 2D GIS based mapping and 3D modeling in a wide range of fields including environmental monitoring, municipal planning, engineering, archaeology and architecture.

This tour walks the user through the process of generating 2D and 3D data layers from oblique imagery.

Gaiamatics Solutions Inc. | ObliqueMapper: How it Works

The application of mathematical conditions such as coplanarity and collinearity and the use of bundle block adjustments and least squares minimization ensures that you obtain the best quality data possible from your photographs. There are two stages to determining the external orientation of each photograph in the project: relative orientation and absolute orientation.


Gaiamatics Solutions Inc. | Applications: Environmental Monitoring

Monitor growth and quality of crops for different fields. Determine proximity of cuts to anthropological features. Determine elevations of ground, buildings, etc. Measure distances to roads, rivers, lakes, etc.


Gaiamatics Solutions Inc. | Applications: Planning & Mapping

Determine height of buildings, power lines, roof layout, access points, etc. Determine road centerlines, building footprints, property lines, etc. View traffic flow, rights of way, zoning areas, etc. for planning. Determine locations of signs, fire hydrants, utility poles, etc. Measure distances to other buildings, roads, trees, etc. Non-intrusively examine environmentally sensitive areas. Diagram buildings prior to modification.

With the continual improvements in LiDAR technology and data processing techniques, high resolution Digital Elevation Models are now becoming available for detailed GIS analysis such as hydrological modelling, urban management, and shoreline monitoring. Gaiamatics Solutions is currently developing a stand-alone LiDAR processing software package, LiDAR Workbench, that allows the user to produce 2D and 3D GIS layers from LAS data files.

Most photogrammetric mapping is performed using vertical photography, having the advantage of being easier to automate processing and combine the results with other GIS data. Although direct map products such as orthorectified photos are difficult to produce from oblique photographs, digitizing GIS layers from them is quite simple.
