<p><strong>Abstract.</strong> Maps is a valuable tool for the geographer to do geographical research. One of the maps’ layer is geographical names. Geographical names belong to the cultural heritage and could help identify the development of human’s civilization. The boundaries that spread throughout a region have the characteristic of constraining both juridically and legally-formal up to its social aspects. However, the regional borders that have previously been determined are now open to modifications over time. The objectives of this research are : 1) analyse the multitemporal maps as the source of geographical names dynamic inside an area; 2) interpret data of dynamic geographical names obtained to be the basis of regional boundaries alteration. The historical map collection of the Royal Tropical Institute in the Library of Map Leiden University (Maps of Magelang from 1855, 1915, 1938, 1940), the topographic map of the U.S. Army Map Service (AMS) (printed in 1945), the Indonesian official topographic maps (Peta Rupabumi Indonesia-RBI) dated 2001, the Google Maps 2018, and the OpenStreetMaps 2018 are altogether utilized in studying the geographical names dynamic of both Magelang Municipality and Magelang Regency. The multitemporal geographical names data are later to be employed to assist the analysis of regional dynamic. We applied the descriptive qualitative method in this research. The existing maps published during the colonialism era and post-Independence Day (1945) can be beneficial to locate the development of regional boundaries and as a resource of multitemporal geographical names. The existence of Magelang Municipality physically has been found since the region belonged to Kedu Residency. On the other hand, the administrative borders were first emerging in a map issued in 1938. The maps from 1855 to 2001 showed that administrative borders of the regions and geographical names examined before were bound to change, mainly on district names. This matter happened due to the proliferation and integration of regions within the Municipality and Regency. Although the borders appeared the same on some of the maps (the 1855 version was similar to the 1915’s and from 1938 to 1945 showed the parallel border lines), the maps showed different geographical names. The orthography of geographical names is experiencing changes as well, from using diacritic to using the Perfected Spelling System (Ejaan Yang Disempurnakan-EYD).</p>

Development of land-cover spatial database using satellite imagery: lesson learned from southern part of Sumatera," Proc. ABSTRACT Development of spatial databases for systematic thematic mapping is a complex activity, as compared to mapping a small area with arbitrary boundaries. This research was conducted in the provinces of Riau Islands, Bangka Belitung Islands, Jambi, and Bengkulu, southern Sumatera. The stages of spatial databases development involved remote sensing, GIS, and cartographic activities. A synoptic overview of the landscape was carried out prior to the spatial database development. The landscape complexity was assessed using landscape-ecological approach, which was implemented in the delineation and classification. The remote sensing process started from spatial data collection of various images with various spatial resolutions, image pre-processing, followed by image analysis and interpretation. Pan-sharpened Landsat-8 images (15 meters) were used as main data, supported by SPOT 6/7 imagery (6 meters), Sentinel-2A imagery (10 meters) and DEMNAS digital elevation model (8 meters) for particular areas. This stage gave consequences to the multiscale analysis in the process of land-cover delineation. The GIS process comprised the stages of compiling the interpretation results to form a seamless mosaic, topology construction, coding into Indonesian Geographic Element Catalog (KUGI) standard, metadata development, followed by topology checking. Those processes aimed to achieve a single map of Sumatera at 1: 50,000 scale. The cartographic layout design was the final stage of the spatial database development, where the land-cover classes symbol was also carried out in accordance with the established standards. Some problems and solutions in the whole processes were also discussed in this paper.
