Content standards for geospatial metadata and their use

Abstract

*-2mm Among the many GIS standards that provide interoperability of (geo)spatial data and related web services, we can identify a limited but important group of standards, intended to catalog spatial data sets and services. Many of currently used standards are based on international ISO 19115 series and their national profiles. Among them are two Russian national standards developed by the Technical Committee (TC) 394 Geographic information/Geomatics of the Federal Agency on Technical Regulating and Metrology (Rosstandart): the GOST R 57668-2017 “Spatial data. Metadata. Part 1. Fundamentals” and the GOST R 57656-2017 “Spatial data. Metadata. Part 2. Extensions for imagery and gridded data”. The analysis of Russian, foreign and international geoportals with metadata editing, validation and publishing functions has been carried out, including using ISO 19115, FGDC-STD-001-001-1998, DIF, Dublin Core and open source software GeoNode, GeoNetwork, GeoServer, etc. The results of the analysis can be useful in selecting effective spatial metadata management systems in the scientific geoportals.
