摘要：Weather plays a significant role in the operation of various facilities and industries in the world. 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
