Abstract

The article analyzes the methods and sources of obtaining data for knowledge bases of technical, technological, organizational measures on water and land management planning in reclaimed areas. The main sources of data obtaining were determined as following: data in XML, CSV and JSON formats from the sites of relevant institutions, remote sensing data, scientific developments and research results, reporting records of water management organizations, etc. The main obstacles that may occur when obtaining the necessary information were identified. The structural and functional scheme of providing the user with a single database access point is presented. For this purposes a node for data collection, storage and processing (sub domain http://ewater.iwpim.com.ua and a server available in IWP&LR) with the functions of remote data collection, their pre-processing, structuring, combining, short- and long-term storage is offered. The structure of the database for processing complex information by subject areas (lists, hierarchies, relationships, structuring libraries, principles of classification) for presentation in the form of "essence-relationship-characteristics" is proposed. As part of a single Internet portal, it is planned to present the following information and reference systems: "Integrated land and water management"; "Land consolidation"; "Private-public partnership". To ensure the specified functionality of the Internet portal, its work will be based on comprehensive information and analytical environment that is a multilevel system, the basis of which is a database of metadata linked to information sources, services and direct access to them. The analysis of the requirements to the software necessary for accumulation of database information and the further performance of the portal was carried out.
