An Automated Data Acquisition System of Landslide Movement in a Heavy Snow District

To reveal the relation between snow melting and landslide occurrence, we developed an automated observation system using a handheld computer in 1987. However, the quality and quantity of data limited processing in this system. To solve these problems, we designed a new automated data acquisition system in 1991. We report here the outline of this system, improved points, new problems during one year of operation with the new system.
