Abstract
Technologies and software components developed for geoinformation web systems and geoportal services are considered. The program and user interfaces, implementation features, the general architecture of the projected systems are discussed. In particular, we consider a subsystem for visualizing the web map data, a CSW directory service, a style editor for geoportal maps and layers. Examples of completed developments and experience of implementation are given.
Highlights
Development of geoportals and their various components, i.e. cartographic web interfaces, distributed storage systems for spatial data, associated metadata management systems – are one of the modern trends in the development of geoinformation technologies [1, 2]
The wide range of tasks performed by this system, which are related to processing of large volumes of cartographic information and provision of tools for information interaction between users, requires the system components to have a developed functional part, and effective and highquality user interfaces [7]
Templates allow to change the order and form of the attributive data output according to the objects in map layers, including different style design
Summary
Development of geoportals and their various components, i.e. cartographic web interfaces, distributed storage systems for spatial data, associated metadata management systems – are one of the modern trends in the development of geoinformation technologies [1, 2]. Created in the first edition about 10 years ago, it is constantly developing, getting improved in the framework of the basic fundamental and applied research, with partial support of integration projects of the SB RAS and various scientific foundations, in the implementation of commercial custom information systems It has successfully proved itself as a software and technological basis for resource-intensive information and analytical systems of the regional level for tasks of various subjects, ex. The wide range of tasks performed by this system, which are related to processing of large volumes of cartographic information and provision of tools for information interaction between users, requires the system components to have a developed functional part, and effective and highquality user interfaces [7] This scientific work represents a number of software and technology solutions implemented for the geoportal recently.
