In the southern part of Sumatra, there are two types of stilt houses: highland Accepted: 2019-07-29 that there is a fault crossing the reservoir.

Both architectures are developed by different ethnic out by conducting GNSS campaigns at 15 monitoring stations simultaneously. However, those Keywords: groups spread along different riverways. This study focuses on identifying and analyzing the Vernacular Architecture, campaigns were not well designed. With such a design, it took many instruments and spent influence of the riverway in the typology of the vernacular stilt house. The architectural typology Riverway, much money. For the next GNSS campaign, it should be designed so that the optimal network andKeywords: Ethnic Culture data was confirmed by field observations and interviews. The analysis was carried out through baseline correlation, conguration is obtained and the cost can be reduced. In the design of deformation monitoring the Geographic Information System to correlate the influence of the riverway and the ethnic sensitivity, network, sensitivity criteria become very important for detecting the deformations. In GNSS GNSS network, culture on the distribution of the architecture and its transformations. The results show that the relative positioning, the baseline components are correlated, but this correlation is oen ignored.
