Geographic information system of landslide Kostanjek: integration of real-time GNSS monitoring data with other sensor data

The Kostanjek landslide monitoring system consists of more than 40 sensors permanently installed at the more than 20 locations in the field: (1) sensors for displacement measurement (GNSS receivers, short- and long- span extensometers) ; (2) sensors for hydrological measurements (rain gauge, outflow weirs, water level sensors, piezometers) ; and (3) sensors for geophysical measurements (accelerometers). This paper shortly presents concept of the Geographic information system (GIS) of Kostanjek landslide which has been developing with the primary objective: integration of real-time GNSS monitoring data with other sensor data. To integrate and visualize GNSS monitoring data, GIS is connected to MS SQL database and it reads GNSS data, transferred to server via communication devices. A new MS SQL database has been created for storing measurement data, and new application has been developed for import and geolocating data which are transferred to server manually. To integrate and visualize sensor data, GIS is connected to sensor database in MS SQL database. The GIS functions are realized using ESRI ArcGIS software. An ArcGIS comprehensive map is created and it shows topographic data, landslide features, GNSS monitoring data and sensor data. The users can use all the ArcGIS functions for creating their own maps and analyze data. The main advantage of data integration into one GIS system is to enable consistent and reliable framework for long-term archiving of all types of data which will be used in further analyses.
