Design of Digital Re-planning Model for Informal Settlements Using Geographic Information Systems

Abstract

The process of re-planning settlements is a complex process, governed by technical foundations, legal regulations, procedures and practical steps, in order to improve and develop these settlements to be at a perfect planning level, with minimum possible damages. Execution of this process manually leads to slow down the solution with disconnected procedures and sometimes increases the complexity of the problem by losing time, effort, cost and decrease the accuracy .In this research a new method had been proposed depending on digital systems to execute re-planning process by analyzing the foundations and regulations that governs the re-planning process and design the required digital solutions for its implementation applying the analysis tools of geographic information systems softwares together with its capabilities of input and processing of spatial data and their attributes in one digital database which enables its efficient integration, quick retrieval, ease of analysis and presentation. This method contributes in making re-planning process easy, quickly, secured, precise and of low cost.Aerial photo graphs had been used as a source of spatial data, non spatial attributes had been collected from the field using forms designed for this purpose and ArcGIS software had been used to execute the steps of the process in the study area.
