Nowadays, there are many sources of weather data maps and tables. Naturally, there are many information systems created to manage and to manipulate weather-based data. The function of an information system is to improve one's ability to make decisions. An information system relates to a chain of operations lead to planning the observation and collection of data, to storage and analysis of data, to the use of derived information in decision-making processes. The creation of a GIS database almost always represents the most significant investment in a GIS project. Therefore, data management becomes the most important part of GIS. Various data structures and exchanging different types of data cause serious problems at the beginning phase of GIS. Recently, web-based GIS with the rapid expansion of internet and the World Wide Web is regarded as one of important issues for web application, and several GIS products running on web browser have been announced. The system used in this study has two main differences from other web-based GIS applications. It is real-time and gets data from sources simultaneously in exact time intervals that users defined previously, and secondly, all the developing and publishing tools used in the system are open sourced. Aim of this study is to create a web-based, free and open sourced GIS that can work with different data formats by exchanging and presenting data as a real-time map on web. 1. INTRODUCTION structure and development of it cannot be derived without careful examination of spatial and temporal relations of weather Information technologies have gained importance in the data. Distinguished from the other information technologies, worldwide organizations due to their efficiency with low costs. GIS offers a set of functions to analyze and relate spatial data. Naturally, developments in computer and information systems, During converting information into GIS, analysis tools can be especially data management systems, directly affect GIS. Data used to solve more complex business problems. Support of real- management is the most important part of GIS. Various data time maintenance of geographic related data and the structures and exchanging different types of data cause serious distribution of updates to all relevant groups within an problems at the beginning phase of GIS. Although organization in timely manner is realized. This improved access organizations and individuals involved with GIS have to current data increases the overall effectiveness of information developed many different solutions, data exchange still remains users. With the right weather information delivered at the right as one of the main problems. However, development of time, many business leaders could make profitable decisions computers and data systems linked with some problems, they (Vadlapudi, 2003). Therefore, combining real-time and weather also have opened new perspectives of creating and managing information has very significant potential for improving data systems easily and economically. Furthermore, expansion weather-related decision support systems. GIS offers much of the computer systems and advances in internet related more than a typical “display” of weather graphics, and provides technologies extend GIS in a new horizon. Due to development the capability of combining the weather data itself with of the internet technologies; collecting data, delivering virtually any other geographically based information, and make materials (maps), manipulating and updating data becomes it possible to calculate meaningful value-added results easier. The recent technologies provide lots of tools for spatial (Sznaider, 2004). technologies and data modelling. 1.1 Objectives of the Study As weather is the statement of the physical conditions at an instant, forecasting is of concern to one and all living bodies The objective of this study is to create a weather processing over the earth. As such, time immemorial weather forecasting system by integrating weather data with different structures is a subject of great concern for the physical scientists collected from different sources in various formats, in a web- (Saseendran, 2003). Most of the organizations like based real-time GIS. transportation, agriculture, water and emergency management need specific weather requirements. Various methods were The detailed objectives are: developed and used by scientists to observe, and monitor weather-related information.
