Change Detection, different from the data, should Geometric Correction




Change Detection, different from the data, should Geometric Correction? The answer, already barangtentu need (said the so and so); as it is unlikely we will get results as expected if two different data (in this case the satellite remote sensing image data) is done for analysis / detection of changes. Case in point, the data used is the 1972 landsat mss compared with Landsat TM imagery in 2006. Is it still necessary geometric correction? In terms of spatial resolution, of course, different where the landsat mss has a spatial resolution of 60 meters while Landsat TM has a spatial resolution of 30 meters. But let's try to examine the geometric side of the first. Please observe and study the picture above and give advice or answers to questions.
