The role of modern GIS in processing of cartographic and thematic information are defined. Specified the data sources which are used for the production of geographical bases of the software systems. It defines a set of validation rules of topological dependencied for mapping forest inventory database. The analysis of the detecting possibility of hidden errors in GIS information resources in forestry and determined the development direction of the specialized module diagnostic error on the example of «GIS Lisproekt» system. Obtained types of errors which can be detected by means of ArcGIS. Also there are pointed on errors which are not available for detection using automation. Proposed solution to address these shortcomings.
There are established the means of checking and correction of topological errors in modern GIS which designed to identify and correct the most common errors in geodata. For example, in the cadastre of real estate registration system the errors which are highlighted can be detected by ArcGis means, for example, imposing boundaries areas, the intersection of boundaries, outline, must not have dangles, «undershoot» or «flight» characteristic points of the boundary of land, land is on the territory of another cadastral quarter. However, for example, it will not be revealed patchwork, turning borders and other. In order to detect and eliminate such errors, as well as to automate topology verification process it is advisable to create additional domain-specific testing to regular full-featured GIS capabilities modules. An example of such module is described in [6].
There are defined the features of geodata in the management of forest management (Fuzzy 'morphology' of forest sites, historically low accuracy of their representations) are such that the topology errors (primarily accuracy error) may be the subject of increased attention. Although the forest to represent objects potentially requires less accuracy than, for example, real estate cadastre, the number and importance of factors influence the accuracy of here anymore. In this connection, it is possible and promising diagnostics topology errors based on fuzzy rules that define the boundaries of plausibility and the nature of forest management projects. The smportant role in the creation of these rules are given to the authors of the spatial and temporal relationships between objects of forest management.
