Land use/land cover changes in Owerri Municipal and its environs which included Orogwe, Ubomiri, Emii, Uratta, Ihiagwa Egbu were studied as being driven by rapid population growth for urbanisation. The study applied the digital technology of Remote Sensing Geographic Information System (ARC GIS 9.3 Version software). These tools implored to generate land maps period; 2005, 2010 2015 determine a...

Uncertainty exists widely in geographic data. However, it is often disregarded during data analysis and decision making. Proper visualization of uncertainty can help map users understand uncertainty in geographic data and make informed decisions. The study reported in this paper examines map users’ perception of and preferences for different visual variables to report uncertainty on bivariate m...

This paper attempts to describe the state of Rainwater Harvesting (RWH) techniques and the contributions of GIS and Remote Sensing (RS) technologies for RWH in The Syrian Desert (AL-Badia). Studies were conducted using physiographic factors of The Syrian Desert (the natural factors, the climatic factors, the pastoral cover, and animal wealth) for the applications of GIS and Remote sensing techn...

Introduction: Geographic information systems (GIS), and more specifically remote sensing, have been used within the geosciences for well over two decades. In that time, the ability to handle a variety of increasingly voluminous data (both vector and raster) has allowed continued data analysis and exploitation within mainstream GIS. The uptake and use of GIS has not been mirrored within the plan...

Original scientific paper In recent years information technology has grown very rapidly. In the context of GIS, Free/Open source concept and also three-dimensional implementation have had more development too. The usage of these types of software is increasingly growing because of reasons such as security, open standards, vendor independence. In this regard, one of the most significant problems...
