The advantages of using photogrammetry in mapping and surveying

Photogrammetry is the method of collecting measurements from photographs by analyzing an object’s surface points. After measuring a series of overlapping photos, computer software is used to stitch the images together, creating not just a 2d image but also a 3d model. The areas, lengths, volumes of structures, and other sites of interest are measured using these models/images. The term photogrammetry is derived from the terms “photo” and “meter.” it simply refers to the measures derived from pictures.

Today, photogrammetry is a popular surveying and mapping technology used for site planning, topographic mapping, earthwork volume estimate, and image-based mapping, to mention a few applications. Reliable information regarding physical items and the whole environment is considered. Aerial and terrestrial photos are taken, recorded, measured, and analyzed.

Photogrammetry entails precise project design, picture retrieval, image processing, image correction, data collecting, and eventually the display of the finished product. Photographs for photogrammetry are taken with a metric camera, sometimes with a standard camera, and sometimes with digital sensors. Images are often recorded using equipment installed on a satellite, aero plane, helicopter, or tripod that is put up and subsequently mounted on the ground.

If you’re still utilising traditional mapping and surveying techniques, it’s time to explore photogrammetry. Here are some photogrammetry advantages that may persuade you.

1. Measured and accurate records

Photogrammetry may create a genuine and permanent photographic record of a specific area while capturing the picture using an aerial shot. Because the picture will include metric features, it will be more than just a graphical record; it will also be an exact and measured record that can be effectively depended on for any endeavor.

2. No fieldwork is required

There is no need for costly fieldwork if the information has to be re-surveyed or re-evaluated. The photogrammetry photos captured may be used to measure, again and again, providing you with fresh information in a handy format. A photogrammetry is an excellent tool for locating missing information, such as insufficient offsets for cross-sections.

3. Better correlation with data sources

By classifying both cultural and physical elements, photogrammetry provides a wide perspective of the project area. Line studies’ large mapped area might help you match it more with data sources than other conventional approaches.

4. Excellent for difficult-to-reach places

Photogrammetry is ideal for usage in areas that are difficult, dangerous, or even impossible to visit. It is an excellent surveying technology that may be employed effectively in locations where fieldwork may be hazardous to the surveying crew’s safety.

5. No disruption to traffic

Road surveys may be carried out using photogrammetry without creating any disruption to traffic or harming the field crew. Because photogrammetry includes elevation data as well as road details, it may be seen at the office rather than on the real field.

6. Easy-to-understand information

The coordinates of each point in the mapping field may be assessed using photogrammetry without any extra work or expense. Once captured, aerial pictures may be utilised to transmit or explain information to the state, public, transportation, and even federal organisations.
