Abstract

Raster-based processing seems to be a powerful tool for land use planners. Collection of information, processing and visualization are much easier in this system in comparison with other vector systems. All visual maps, plans and drawings can be precisely scanned and shaped into desirable forms. Grid-based modules of GIS software packages include commands by which the user is able to perform various examinations according to needs. The only problem is that the user must be familiar with GIS software modules in order to be able to use this system. Users’ possibilities are also developing. Therefore, the Grid-based analysis is great news for planners who have been waiting for more than twenty years for computer tools to help advance their tasks.
This paper includes a method based on grid for expansion of computer applications in land use planning. In this paper, we divide the planning process to a number of stages and present suggestions for utilization of digital information at each stage.
In addition to theoretical examples, one case is described in detail. This project is an analysis of land use implemented by a group of students of the Helsinki University of Technology.
