استخدام نظم المعلومات الجغرافية (GIS) لقياس سهولة الوصول الى الخدمات العامة في مدينة الحلة

Abstract

The efficiency of spatial distribution of public services is one of major objectives of physical planning of cities due to its direct relation with human needs of residents and the ease to reach it. The objective of the study is to measure the accessibility to public services as an indicator of the efficiency of its spatial distribution with respect to residential areas of hilla city. Administration, Commercial, Education, Health and Industrial services had been selected as a case study of most important services. Three most common measuring methods used, namely:1) The distance to the closest service, 2) The number of services within n meters or minutes, 3) The mean distance to all services. Geographic information systems (GIS) used to measure (Euclidean) distance between the centroid of residential areas and public services, and to determine the number of services within (200, 500, 1000 m) radius around the centroids of residential areas .Results showed that education services had highest degree of accessibility, followed by commercial and administration services with little deference, health and industrial services came latter respectively.
