<p>Site coverage is an important index to learn spatial development pattern of the city. In this paper, with the help of spatial analysis functions of GIS, buffer and sector analysis are imposed in pursuit of finding possible spatial distribution rules of Beijing taken flagpole in Tian’anmen square as center. The results of sector analysis indicate that the building densities in such superior geographical condition areas as southeast and south are higher. Building densities of northern and western areas are low because of their bad terrain. The results of buffer analysis indicate the density of city center is the highest and have a negative relation with the augment of distance. That is to say, the average building density of center areas (buffer 1, 2 and 3, about 7.5km away) is about 26%. The average building density of transition region of city and countryside (buffer 10~20, about 25~50km away from center) is about 9%. The average building density of exurbs (after buffer 20~50km away from center) can't reach to 3%.</p>

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.

Many environmental damages and disasters represent environmental problem because the supportability of life environment is exceeded. This excess is occurred because environmental supportability is weakened. The problem of human in using the space in the environment is that how to make the environment and its ecosystem to support the living in sustainable manner to produce reliable welfare. One effort to balance the use of natural resource and living environment is through spatial management to preserve the life environment function. The supportability of life environment is the most important consideration in the space order, especially the arrangement of regional space order plan (RTRW – Rencana Tata Ruang Wilayah) or the evaluation of space utilization. An approach used to determine the supportability of environment is through spatial data approach. The development of geographic information system(SIG – Sistem Informasi Geografi) brings a new hope for the optimization of environmental-based development, the provision of spatial information about the characteristic of a region, and the ability of SIG in manufacturing the spatial view for detail land opening and closing. The objective of this research is to evaluate the existing land compatibility and RTRW for period 2011-2031 at Ponorogo District based on the land capability and to provide recommendations about space order which aligns with environmental supportability. Research method is spatial analysis. This analysis produces map overlay as the visualization of result of land capability clarification. Result of research indicates that the use of existing land at Ponorogo District is already compatible to the direction of spatial use. However, some lands are not complying with this direction. The land use at Ponorogo District should obey the direction to preserve the landcapability and the environmental supportability.Keywords: Environmental supportability, land capability, spatial analysis, geographic information system (SIG), and RTRW of Ponorogo District ABSTRAKBerbagai bentuk kerusakan  dan bencana lingkungan seringkali merupakan permasalahan lingkungan yang timbul akibat daya dukung lingkungan hidup telah terlampaui. Terlampauinya daya dukung lingkungan umumnya timbul melampaui kemampuan lingkungan yang mendukungnya. Salah satu bentuk upaya menyeimbangkan pemanfaatansumberdaya alam dan lingkungan hidup adalah melalui proses penataan ruang yang berbasis tercapainya kelestarian fungsi lingkungan hidup. Daya dukung lingkungan hidup seharusnya menjadi salah satu pertimbangan terpenting dalam penataan ruang, baik dalam penyusunan Rencana Tata Ruang Wilayah (RTRW) maupun dalam evaluasipemanfaatan ruang. Salah satu pendekatan yang dapat digunakan untuk menentukan daya dukung lingkungan adalah melalui pendekatan berbasis data spasial. Melalui perkembangan sistem informasi geografi (SIG) memberikan harapan baru untuk mengoptimalkan upaya pembangunan berbasis lingkungan, selain untuk memberikan informasi spasial akan karakteristik suatu wilayah, SIG juga dapat memberikan gambaran spasial akan peruntukan dan penutupan lahan secara rinci. Tujuan dari penelitian ini adalah untuk mengevaluasi kesesuaian lahan (existing) maupun RTRW 20112031 Kabupaten Ponorogo terhadapkesesuaian penggunaan lahan berdasarkan kemampuan lahannyaserta memberikan rekomendasi penataan ruang yang selaras dengan daya dukung lingkungan. Penelitian ini menggunakan Metodeanalisa spasial. Analisa spasial dari hasil overlay peta sebagai visualisasi hasil pengklasifikasian kemampuan lahan. Dari hasil penelitian diperoleh bahwa penggunaan lahan (existing) Kabupaten Ponorogo sudah sesuai dengan arahan pemanfaatannya ruangnya, namun masih ada juga yang belum sesuai dengan arahan pemanfaatannya. Pemanfaatan lahan di Kabupaten Ponorogo harusnya disesuaikan dengan arahan penggunaan lahannya agar dapat sesuai dengankemampuan lahan dan daya lingkungan.Kata kunci: Daya dukung lingkungan, kemampuan lahan, analisa spasial, sistem informasi geografi (SIG), dan RTRW Kab.

A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present spatial or geographic data. GIS applications are tools that allow users to create interactive queries (user-created searches), analyze spatial information, edit data in maps, and present the results of all these operations. GIS (more commonly GIS science) sometimes refers to geographic information science (GIS science), the science underlying geographic concepts, applications, and systems. GIS can refer to a number of different technologies, processes, techniques and methods. It is attached to many operations and has many applications related to engineering, planning, management, transport/logistics, insurance, telecommunications, and business. For that reason, GIS and location intelligence applications can be the foundation for many location-enabled services that rely on analysis and visualization.

Three-dimensional (3D) buffer analysis is among the basic functions of 3D spatial analysis, and it plays an important role in 3D geographic information systems. The rapid development of the 3D Discrete Global Grid System (DGGS) provides a new method for the 3D spatial analysis of geographic information. According to the spatial topology characteristics of the 3D DGGS and the concept of dimensionality reduction, a 3D buffer analysis method based on the spatial grid of the Earth system is proposed to solve the problem of the buffer algorithm of a space object being unsatisfactory at present. In this paper, we present a method to calculate the distance between cells based on the side length of the spherical grids according to the geometric characteristics of the grids. For the grids of a geographic object, we describe the Euclidean distance expansion algorithm and the radial elevation expansion algorithm that helped us to obtain its 3D buffer. Finally, in terms of algorithm complexity and visualization effect, compared with the traditional raster buffer algorithm, the method presented in this paper has lower complexity, an improved visualization effect, and stronger generality.
