Abstract

Rote Island is one of the islands in southern of Indonesia. This region experiences very high geological and geodynamic processes. This is evidenced by the abundance of seabed rising, and there is a dead sea lake area that has a higher salinity than the sea. Biodiversity on Rote Island has endemic and unique flora and fauna. This study aims to create an integrated system of inland waters resources on Rote Island with a multidisciplinary approach. Inland water resources on Rote Island number more than 80 lakes and ponds. An inland water resource on Rote Island is a saltwater environment. The extraction of geobiophysical information on inland water resources is needed by studying various aspects of multidisciplinary. The aspects studied are limnology, water quality, conservation of forest resources, geology, geodynamics, water resources, geodesy and geomatics engineering. All geobiophysical information needs to be integrated into an integration system. This is useful for efficiency and effectiveness in the utilization of data and information. This integration system (geovisualization) is in the form of WebGIS and storytelling maps. This integration system is dynamic so it can update its latest spatial information. This integration system can be used to promote Rote island tourism. This integration system can be accessed via the website geopark4rote.com. This integration system can be applied in other regions so reached one map policy and a system for inland water resources will be realized in Indonesia.

Abstract

Rote Island is one of the islands in East Nusa Tenggara. In this island, land changes occur significantly. This land changes can be detected by Landsat images. These images are obtained from the big data engine. The big data engine used is the Google Earth Engine. This study aimed to detect land changes with harmonic modelling using multitemporal Landsat images from the big data engine. Harmonic modelling is used in monitoring changes in Normalized Difference Vegetation Index values in a multitemporal manner from Landsat images. Processing is done using the Geomatics approach. Land changes on Rote Island generally occur on coastal and savanna. Land changes on land generally have vertical deformation on its movement and horizontal on the savanna. The land changes accuracy result is 95% in 1,96σ. This method can be used for rapid mapping of land changes monitoring.
