STUDY CHANGE DETECTION BY USING NDVI FOR LAND COVER AND LAND USE FOR AL HIMREEN AREA

Abstract

Change detection method is one of the important subject of remote sensing. Which is sufficient to determine the changes for period of time to land cover and land use. In this paper used NDVI for change detection to Al Himreen area by using satellite images for land sat-7 ETM+ for 2000 and 2006 . After observation the results of standard deviation for four band to first time was 47.82. The standard deviation for same band in second time was 45.28 , so its lower about 0.02%.The standard deviation for five band to first time was 84.73 .This value low in second time at 49.13. Its lower about 0.3%. When using NDVI for these bands and calculate standard deviation was 61.14and 49.80 for first and second times respectively. The standard deviation is low about 0.11% . This method was successfully for changes detection for lands cover and lands use
