Abstract Landslide danger is well known and improved prediction can save lives and property. To predict the landslide danger for every geological structure, the government and geological organizations use geoindicators which monitor the sites and warns the scientist that “in Baybaksay there is a dangerous situation ” or “Earth movement occurred 124 km southwest by the Tashkent–Charvak road”. All this is done with the help of geological indicators and some factors for the current geological Earth structure. Methods of measurements are done with the help of special equipment on site, which transfers information via GPS or mail or other methods of information transfer. The whole world uses Black bird satellites or others, which makes images of the surface of the world, and can see the changes which happened in the place scanned. Changes in places can be seen on different light spectra and changes in the Earth which happened can also be seen within 4–5 hours with the help of remote sensing. The method we used is a combination of geoindicators (humidity of ground, quantity of deposits lately, shifts in ground and other) and remote sensing—monitoring from the satellites so we can have one centre in the world—which has databases with all geoindicators of the structure of the ground of the world. Some say that it is impossible to watch over the ground from satellites, it is suggested that all the work must be done at the ground surface, but we have never tried to do this. The greatest improvement in this case would be that every government would not need to buy new satellites or expensive equipment, they would just need to pay a monthly fee (much cheaper). The information centre, which will be only one on Earth, will process all the data from satellites and will compare it with geoindicators and tell us where dangerous processes are going on and will show the model of what will/can happen, and if there is a need to evacuate local citizens.
