Abstract

The use of Unmanned Aerial Vehicle (UAV) to take aerial photographs is increasing in recent years. Photo data taken by UAV become one of reliable detailed-scale  remote sensing data sources. The capability to obtain cloud-free images and the flexibility of time are some of the advantages of UAV photo data compared to satellite images with optical sensor. Displayed area at the data shows the objects clearly. Rural area has certain characteristics in its land cover namely ricefield. To delineate the area correctly there is an object-based image analysis methods (OBIA) that could be applied. In this  study, proposed a novel method to  execute the separation of objects that exist in the data with segmentation method. The result shows an effective segmentation method to separate different objects in rural areas recorded on UAV image data. The accuracy obtained is 90.47% after optimization process. This segmentation can be a valid basis to support the provision of spatial information in rural area.

Abstract

Land order in an urban area that is not based on complete and reasonable spatial information an cause an unintegrated development program. Therefore, spatial information that can analyze the information to make a decision of land order is greatly needed. To present the most reasonable physical data of the urban can use the data of remote sensing as a main source, because the data an present not only a high temporal resolution, but also a complete object. Along with the advance of computer-based GIS, the data of remote sensing can be integrated with GIS. In addition, the data sharing can be used in various sectors. Thus, both updating and mutual exchanging of data can be done easly.

Abstract

The study aims to estimate water storage index (IPA) of six sub watersheds (Panjang, Rengas, Legi, Galeh, Parat, and Sraten) in the cachment area of Rawapening lake by using Geographic Information System. Water storage index can be calculated from average discharge (m3) devided by water requirement (m3) for each land cover/land use. Landuse information is obtained from Indonesian Topographic Map scale of 1:25.000 as updated by using SPOT image (2006), while surface water availability data was obtained from the ministry of public works. The results indicate that 1) IPA of Panjang Subwatershed was categorized as good condition with an index value of 1,49; 2)IPA of Rengas and Legi sub watersheds were categorized as moderate condition with index value 0,76 and 0,55; 3) IPA of Galeh, Parat, and Sraten sub watersheds was categorized as bad with index value of 0,3, 0,15, and 0,33, this watershed need to be improved especially an effective water resources plan, allocating and distributing of water according to priority establishment.
