地理情報の解析を主眼としたパーソナル・コンピュータ用のラスター型GISに関する考察

抄録

In recent years, GIS is used increasingly and rapidly for researches and analyses. Most of these GIS are the system based on vector data. On the other hand, many type of inf ormations are used for researches and analyses of environmental management, land conservation, regional planning. So, adding GIS based on vector data, it seems that GIS based on raster data are necessary. They can directly connect remote sensing data and geographic information, and simplicity of data structure used on them help user to develop exclusive function easily.
Therefore, in this study, we tried to study on the simple type of GIS based on raster data using a personal computer (PC-9800) . This paper reports about the basic idea of system production, functional analysis basing on analytical examples, discussion on hardware and software and production of pilot system, and prospect for the extension function of the system in the future.
