DEVELOPMENT OF A MULTIPLAYER GEODATABASE FOR CREATING AN INTERACTIVE MAP USING JAVASCRIPT

Abstract

Geoinformation technologies are widely used in all spheres of human activity. In a short period, GIS technologies have proven themselves to be a necessary tool for compact data storage and rapid updating of information. In the presented work for the rst time, a web GIS was developed for permafrost conditions on the territory of Yakutia using spatial data and sources (monographs and data of tables). Web GIS is a geoinformation system on the Internet, whose users can view, edit and analyze spatial data using conventional web browsers. The objective of this work was to create a uni ed geocryological database of the Permafrost Institute for the territory of Yakutia. The main tasks that were considered were: to develop the structure of the web GIS database; to determine the programs for working with the database; to assemble a database for the Permafrost Institute; to write code and create a website. The work presented a step-by-step making of a website using PostGIS for storing vector data, program GeoServer using spatial reference data and WMS service, and also presents part of the website code in the JavaScript programming language using open source library the Lea et and a set of tools the Bootstrap. The main results of the research are as follows: the development of the structure of the website with the creation of a spatial database, as well as the collection, systematization of cartographic, attributive, graphic, and textual information with the compilation of GIS with a complex of thematic layers with the attachment of databases on the example of Yakutia.
