ABSTRACT
Software design and development of web-based geographic information systems and cartographic services for environmental monitoring problems are discussed. List of requirements for appropriate information & communication infrastructure has been formulated. It includes a number of items, such as organization of the technological environment for the integration of generated information resources, design and implementation of environmental monitoring facilities databases, development of new computational and mathematical models and methods for environmental monitoring data interpretation, etc. Integrated web based geographic information system for environmental monitoring in the area of oil and gas industry in Krasnoyarsk region territory is presented. The developed software is based on the leading GIS and web mapping technologies, frameworks and toolboxes, free and open source software libraries. In particular, we discuss developed software components, such as web interface for spatial metadata catalog, web mapping interactive tools, map data direct access by OGC protocols, specific services for ecological web applications, geoportal programming interfaces.
Keywords: environmental monitoring, web mapping, spatial data, geoportal, web-gis
INTRODUCTION
Effectiveness of monitoring the state of the environment is largely determined by its information and analytical software. To manage successfully the territory and to manage efficiently its resources, you need a good understanding of the generalized characteristics of its condition and to be able to as soon as possible to receive the necessary decision-making detailed information about management facilities in visual form.
These requirements can be achieved through the establishment of modern information and communication infrastructure, environmental monitoring, which allows you to assess objectively the situation in the operational mode, and generate options for management decisions.
Environmental spatial data is digital data concerning spatial objects, including information on their location and features, on their spatial and non-spatial attributes. Spatial data is data on geographical objects, which represents the formalized digital models of material or abstract objects in the real or virtual world [1, 2].
The full description of environmental spatial data consists of two interrelated parts: these are positional data and non-positional data, i.e. descriptions of spatial location and thematic content of the data, of topological and geometric, as well as attributive data (geometry and semantics). Spatial and temporal data is used for consideration of temporal aspects. A representation of spatial data, or a model of spatial data is a...
