Instructions for use
Detect Change is to compare the multi-temporal images of the same area (usually collected for an area in different periods) to determine the type, amplitude and location of change, which has important and wide application value in the fields of Land Use, urban expansion, geological disaster monitoring, ecological environment protection, forest protection and other natural resources.
SuperMap iDesktopX provides a Detect Common Change function, which can serve a variety of image Detect Change scenes, identify the changed plots and generate vector results of interest category change pixels. The function of Detect Common Change can interpret images at a fine granularity, which is usually used to obtain the changes of buildings, roads and water bodies with obvious characteristics.
