ABSTRACT:
The objective of this work is to build a proper Geographic Information System (GIS) data-model that can be used for school
mapping planning, where all schools with attribute data would be available for problem solving and decision-making in Education.
Thus, the end product of the GIS will be part of an Educational Decision Support System that provides the user with a map of
specific region with focus on the schools locations and all related info to assist decision-makers in either expanding current school or
suggesting sites for new schools in Jordan, and also, for student and resources location/allocation.
The built GIS-Data-model is composed of the schools layer, large-scale streets, directorates, sub-districts and Governorate layers
with population data. IKONOS Geo imagery and more reliable small-scale vector data format are to be integrated with the current
GIS-data-model to build a detailed geospatial-database for school mapping planning purposes. However, there are several problems
associated with this mainly because of the different projection systems each dataset is based on and due to the scale problems.
This paper reviews the original GIS-data-model format, the used projection systems, the management of the geospatial database and
aspects of the project to collect data from ground and satellite semi-rectified image sources and combine the data sets together so
that a high level of tractability and integrity are offered. A status report of the existing uses of the model is given together with an
outlook of expected future uses as an Educational Decision Support System for planning purposes. The paper concludes with the
future trend to build an Internet Wep-mapping site to be available to fit various needs for GIS School Mapping applications, which
would be perfect for decentralizing the Decision Support System between Educational Directorates for data updates.
1. INTRODUCTION
In developing courtiers, the need for GIS and Geo-Imagery is
even more as there are more urban planning problems, and in
many situations, almost no planning strategies. Thus, you need
