Learn about Photogrammetry and Mapping Solutions

Photogrammetry is the process of using overlapping aerial images to extract precise ground position. The word ‘Photogrammetry’ is a combination of three words which basically means light, drawing, and measurement. It is a technique for acquiring dense 3D geospatial data and information.  If any business is searching for some photogrammetric solutions nearby, one must look for the provider that render photogrammetric solutions to meet the user’s needs with the best quality and at a globally competitive price.

Photogrammetry is the process which is as old as modern photography. The science has continued to develop gradually over time, especially in view of the recent technological advancements.

Photogrammetry is used in:

Today, photogrammetry is used for an extensive variety of purposes in the geographical information system (GIS) field, which includes:

• Creating a digital elevation model (DEM)
• Accurate raster image backdrops for visualizing GIS data

Digital Photogrammetry

There are two types of photogrammetry, Digital Photogrammetry, and Hardcopy Photogrammetry. If the digital image is used for the calculation, then it is termed as Digital Photogrammetry. On the other hand, if a hardcopy image is used then it is hardcopy photogrammetry.

There are also two distinct types of digital photogrammetry, which includes:

• Close-Range Digital Photogrammetry

This particular photogrammetry involves the use of a camera mounted on a tripod stand of vehicle. In this method, high-end digital cameras are used to photograph objects from three or more different locations to develop appropriate lines of sight. 

• Aerial Photogrammetry

This method is done by mounting the camera in an aircraft and subsequently taking photographs of the ground. The camera is mounted in an aircraft and is typically pointed vertically towards the ground. Aerial photographs are taken from the air by a special camera mounted in an aircraft flying over the area with the camera axis vertically.

Mapping Issues 

The recent technological advancements in computer vision and machine learning has made the overall process a bit more complex.  The developers of photogrammetric equipment and software face the challenges in providing the mapping solutions that are advanced, and can meet high customer expectations in terms of user-friendliness. Hence, it is crucial to look for digital photogrammetric mapping solutions service provider that can customize the solutions as per the clients’ needs.
