How Does Satellite Image Compare with Aerial Photography

Are you aware of the differences between satellite imagery and aerial photography? From time and again comparison has been made of photographic images produced by these two techniques. The comparison of these two methods began to emerge with the launching of the first satellite. The previous comparisons centered on parameters such as accuracy and resolution. Now the argument continues from a different perspective, and new issues such as extended images, spectral sensitivity, and timing aspects have entered into the discussion.

Role of technological advancement
Before you delve into a comparison of these two techniques – aerial photogrammetry and satellite imagery, you should take into consideration the technological advancements made in these fields in recent times. Nowadays aerial photographers often use a combination of cameras and light detection and ranging remote sensing methods for creating 3D maps. The objective is to provide orthomosaic photo and data on vast plots of land quickly. An orthophoto is rectified geometrically in such a manner that such pictures lack distortion just like maps. Satellite images, on the other hand, have failed to produce both kinds of data at the same time.

Comparison of the two techniques
There has been a significant reduction in prices of satellite imagery. Nowadays in some cases, the satellites visit the same position again and again and sometimes they are done even on a daily basis. This has been a giant leap in technology because previously the failure to visit sites repeatedly now and then was a serious bone of contention. Aerial shots are useful for studying the environment of the earth. These shots are captured from airplanes or helicopters. Aerial photographers make use of powerful tools to gather remote sensing images. It is not possible for the satellites to be positioned at two places at the same time. Airplanes which are equipped with cameras can serve that purpose. If you want suitable cloud cover, then you can attain that objective through airplanes. However, this luxury of waiting is not possible with satellites. They cannot stay in one place; they can just cycle. 

Take help of aerial companies
Nowadays consumers are not willing to settle down for any kind of picture. They now expect pictures to be available immediately to them for assessment of any situation. The comparison of both the techniques is not that straightforward as it used to be previously. Sometimes location can cause a delay in getting the right teams and aircraft. In today’s world, there are many companies who specialize in photographing their own state. So if your country of residence is different from the country which you want to be photographed then do not be disheartened. You can contact one of these professional companies who provide specialized services in these fields.

Prudent decision making
While choosing an aerial company do detailed research on the net. Check out the websites of these organizations providing such specialized services. Do not forget to go through the reviews which have been posted by the past clients. Aerial shots are always a wise choice especially from the cost perspective than satellite imagery.
