Geodatabase or digital spatial database is one of the GIS applications with an integrated database that has become a data source center that can be accessed for information and analysis needs by various existing applications. Participatory digital database has the potency to be used for inventorizing and collecting a complete, comprehensive, and detailed village/sub-district potentials spatial data. This research aims to provide knowledge as well as skills to the community, especially sub-district officials about a standardized spatial-based digital database of village potentials. The study took place in Langnga village, Mattiro Sompe District, Pinrang Regency, South Sulawesi, Indonesia. Methods used in this research are UAV Data Processing, Geodatabase System Compilation, Census and Cadastre Surveys, and Integration of Non-Spatial Data with Spatial Data. By compiling village potentials geodatabases, we constructed a Langnga village’s potentials map which can be used as a reference for planning and development of the village.

Microatolls are massive corals on flat reefs with the colony dying in the center or there is a hole in the middle due to erosion by algae or other micro-borers. This study aims to measure the ability of UAV RGB imagery to identify micro atolls located on reef flats and objects associated with them on small islands. High resolution satellite images were also used to compare their accuracy in estimating the size of micro atolls. Some of the important steps carried out are field surveys, aerial and google earth photo acquisitions as well as mosaics, classification with segmentation based on, shape and color, texture, and shape of object proximity. RGB UAV is used to collect data and it is processed by object-based image analysis (OBIA) classification algorithm and supervised classification. This paper represents the result of UAV data analysis is more accurate and precise than high resolution satellite image data analysis. The diameter of the micro atoll can be calculated and the associated community around it. This technology allows it to be used for monitoring shallow water ecosystems bordering community activities on the mainland of small islands and producing a higher scale.
