| Description
| - This paper has two parts related to identification of area of instability and geotechnical determination of unstable soil/rock mass for the following stability and remedial action analyses. Detail landslides mapping is expected by Autonomous Mapping Airship (AMA), which has been developed within research project. AMA is suitable for mapping of medium-wide areas. Its properties are discussed and compared with other means of aerial mapping in the paper. AMA operates up to 3 hours at a time and can carry INS/GPS unit, modified laser scanner, DSLR camera, thermometric camera or other sensors. Set of detailed digital surface models from different time epochs can be processed as difference models. In combination with geotechnical measurements, this approach can deliver background information for geotechnical stability analyses, which require input data describing the development of surface and subsoil deformations. A research and development project focused on the use of Fiber Bragg Gratings (FBG) for displacement monitoring in geotechnics has been carried out since 2011. A modular borehole extensometer with FBG strain sensors, various FBG displacement sensors, both for subsoil deformation measurements and own FBG interrogator are under development. A chain of sensors with different measuring bases can be used to ensure good sensitivity of depth of the slip surface determination and relatively long time of function. Continuous readout in inaccessible areas and connection of industrially produced pore pressure sensors is possible due to an application of inexpensive signal transfer with the use of telecommunication fiber optics. FBG monitoring system can also perform warnings, when given deformation limits are exceeded. Interpretation of aerial mapping and determination of unstable area extents delivers basic information for effective design of geotechnical monitoring system. The use of fiber optics automated measurements can save costs of site inspection and instrumentat
