Historical photos have significance for historical and social studies. Especially, the introduction of Geographic Information System (GIS) and digitalized historical photos have brought more opportunities and possibilities for interdisciplinary studies and the convenience for normal citizens to participate in the landscape observation. To this aim, this paper first reviews the research related to historical photos and Open GIS, and points out the meaning of historical photos for the Yunnan–Vietnam Railway (YVR). Based on the collected data of original historical photos from archives and the fieldwork data that recorded the landscape along the railway from 2018 to 2019, a WebGIS of Yunnan–Vietnam Railway is designed and implemented with open GIS tools. All the data are processed in the QGIS as vector and raster layers and loaded in PostgreSQL as relational tables. Then, heatmaps are created indicating the density of historical activities of the railway company, the other historical photographers, and current touristic activities. Connected with the PostgreSQL database, the data are uploaded to GeoServer for more GIS functionalities. Finally, the whole system lives in a webpage, implemented in HTML and JavaScript with Leaflet, and the improved functionalities of the Yunnan–Vietnam Railway WebGIS include distance measuring, search engine, and historical information browsing. In the future, further research can be done focusing on the landscape changes along the railway and public participation during the landscape observation.

Kalijambe village is a village located in Bringin sub district of Semarang. The geographical position of the village Kalijambe is still largely in the form of rubber and teak plantations. Thus, the dry season is very prone of fires. The cause of the fire itself is caused by the citizens who burned the bush and grass growing around the rubber plants and teak. In the other hand, this case was not recognized by people that it was the cause of the fire. Geographic Information System to detect the fire location is intended to help Kalijambe  village government to see the areas affected by fire through the coordinate points contained on google map fire. The method used was the method of field survey conducted periodically. This research resulted that the affected areas were known and signed with black mark on the map location.

The objective of this study was to analyze the sustainability to water erosion in the Capim river/PA-MA. Acquired precipitation (GPCC), slope (TOPODATA project), land use and land cover data (MapBiomas) and pedology (Brazilian Soil Classification System) were obtained. Based on these variables, in a Geographic Information System environment, the product representing the sustainability to soil water erosion was generated. A sustainability gradient for soil water erosion was observed in the SE-NW direction, where it was higher near the mouth of the Capim River. The other variables were: clinical component presenting predominance of stability and high sustainability in the south of the basin; land use influences the entire axis of the basin, indicating instability in the medium-low Capim and in the extreme southeast. It was observed that the sustainability to erosion in the Capim watershed is motivated by intensified land use near the mouth. The zoning carried out in the basin is a warning sign for the municipalities of São Domingos do Capim, Rondon do Pará and Goianésia do Pará.

The aim of this paper is to report a brief history of control actions for Visceral Leishmaniasis (VL) from 2006 to 2010 in the Sanitary District (DS) of Venda Nova, Belo Horizonte, Minas Gerais, Brazil, focusing on the use of information systems and Geographic Information System (GIS) tools. The analyses showed that the use of an automated database allied with geoprocessing tools may favor control measures of VL, especially with regard to the evaluation of control actions carried out. Descriptive analyses of control measures allowed to evaluating that the information system and GIS tools promoted greater efficiency in making decisions and planning activities. These analyses also pointed to the necessity of new approaches to the control of VL in large urban centers.

ABSTRACT The Oil Program Center at the U.S. Environmental Protection Agency (EPA) Headquarters is developing geographic information system (GIS) standards to aid EPA's 10 regions in developing and implementing GIS. GIS can support spill response, contingency planning, risk analysis, training and exercises, inspections and enforcement actions, reporting, incident analysis, cost recovery, and outreach. By developing and promoting standards, the Oil Program Center hopes to ensure that GIS development is targeted at the broadest practical user base and considers all aspects of EPA's oil program. In addition, GIS standards will promote consistency between EPA regions, promote data sharing, reduce duplication of effort, and focus attention on using GIS as an analytical tool rather than just as a mapping tool. The standards also may promote greater consistency between the Oil Program Center and other offices within EPA; for example, standards promote watershed-based analysis, which is consistent with other offices' use of watersheds as units of analysis. The standards address the following issues: Minimum essential data elements Data verification and accuracy standards Standard symbols and icons System design and data structure Because the specific needs of regions differ, the GIS tools that they develop will reflect these differences. GIS data standards, however, will promote compatibility across the regions to facilitate collaboration and expand prevention, preparedness, response, and outreach capabilities.

Archaeology is closely associated with spatial or spatial aspects. Because the material archeological data such as artifacts, features, buildings, and sites containing the inherent spatial information in order to keep the data context. The themes of the archaeological research nowadays often reconstructing the spatial aspects of history and culture. Device Geographic Information System (GIS) is clearly greatly assist the process of archaeological research both in the field and during the process of analysis and presentation of information related to the results of the research. GIS has become the main choice for researchers to update the development of archeology that have been all-digital, practical, and effective. Although the use of GIS in archaeological research is very popular in many countries, in fact the use of GIS in archaeological research in Indonesia is still not that popular. This paper presents the use of GIS tools that allowed to be applied by archaeologists that can be adopted in the analysis and presentation of information and research results, conditions of application of GIS in the current archaeological research, as well as the constraints faced. This paper shows that recently the archaeologists in Indonesia is very enthusiactic in using the GIS for the effective spatial analysis tools. The government is also concerned about the importance of GIS in mapping the spatial data of heritage as well archaeological research locations in order to support the acceleration of One Map Policy.Ilmu arkeologi sangat erat kaitannya dengan aspek keruangan atau spasial. Karena materi data arkeologi seperti artefak, fitur, bangunan, dan situs mengandung informasi spasial yang melekat agar tidak kehilangan data konteksnya. Tema-tema penelitian arkeologi dewasa ini tidak sedikit yang bertemakan aspek spasial dalam merekonstruksi sejarah dan budaya. Perangkat Sistem Informasi Geografis (SIG) jelas sangat membantu proses penelitian arkeologi baik di lapangan maupun saat proses analisis dan penyajian informasi terkait hasil penelitian semacam itu. SIG menjadi pilihan bagi peneliti arkeologi dalam mengikuti perkembangan dunia riset yang serba digital, praktis, dan efektif. Walaupun penggunaan perangkat SIG dalam penelitian arkeologi sangat populer di banyak negara, namun kenyataannya penggunaan perangkat SIG dalam penelitian arkeologi di Indonesia belum cukup polpuler. Penelitian ini menyajikan penggunaan perangkat SIG yang memungkinkan diterapkan oleh peneliti arkeologi yang dapat membantu dalam proses analisis dan penyajian informasi hasil penelitian, kondisi penerapan perangkat SIG di dalam penelitian arkeologi saat ini, serta kendala-kendala yang dihadapi. Penelitian ini menunjukkan bahwa dewasa ini perhatian peneliti arkeologi di Indonesia terhadap peran SIG cukup terbuka mengingat kebutuhan perangkat analisis spasial yang efektif. Pemerintah juga menaruh perhatian akan pentingnya SIG dalam memetakan data spasial Cagar Budaya dan Lokasi penelitian arkeologi dalam rangka mendukung percepatan kebijakan One Map Policy atau kebijakan Satu Peta.
