In recent years, the demand for information obtained through remote sensing of the web has been greatly increased due to its high resolution for environmental analysis and topographic and local maps.
Recent satellite techniques such as SPOT and TM, which are Landsat and based on electronic scanning,
can produce images with resolutions of 10 to 30 m.
For the first time, scanned data on ground scale of each pixel equal to 5 meters can be expected from the mission of MOMS-2 and the newer SPOT and TM systems. Over the past decade, great progress has been made in the use of colored and black and white images taken by the Soviet Union's remote sensing department.
The result of the research shows that the highest resolution was for a vast area used for updating maps of
1: 25,000 by KAF-1000 and MK4 cameras.
During the 17th ISPRS conference (Washington, 1992), it was announced for the first time that satellite images taken with the third generation of space-shooting cameras with a resolution of 1-2 meters will soon be used for local applications.
