What is the difference between TDOM and DOM? Where are they applied?
May 24, 2023
TDOM is called the true orthoimage, which eliminates the projection error of the building, and only the top of the building can be seen, and there will be no covering between buildings.
DOM is called an orthophoto. It does not eliminate the projection error of the building. The building is inverted. It often happens that high-rise buildings cover low-rise buildings.
TDOM Before And After Inpainting With Oblique Images
The application of TDOM and DOM is similar, mainly used in agricultural survey, forest survey, environmental protection monitoring, land planning, transportation, urban management, real estate, navigation and other fields. The production cost of TDOM is high, and in the production process, the ground resolution of the image is greatly lost. The ground resolution of TDOM produced by the same original image is not as high as that of DOM, so in practical applications, DOM is mostly used.

What is The Digital Orthomap (DOM)
The Digital Orthomap (DOM) is a computer-generated image of an aerial photo in which displacement (distortion) caused by terrain relief and camera tilt has been removed, combining the imagery features of a photo with the geometric features of a map. More > -

DOM Acquisition Method and Production Process
The digital orthophoto map uses the digital elevation model (DEM) to perform projection difference correction and mosaic pixel by pixel on the scanned digital aerial photos or satellite image data collected at high altitude, and cuts according to the range of the national basic scale topographic map The resulting digital orthophoto dataset.

DOM Production Process
Relevant data needs to be collected before DOM is generated, that is, the data preparation stage, including original digital aerial photos, analytical aerial triangulation results, DEM results, etc. More > -
