OGC services

The exchange of data via the Internet in the modern world is of great importance. The importance of spatial data is recognized in all areas of state administration, local government, the scientific community and the economy.

Given the complexity of spatial data in relation to non-spatial data, as well as the need to standardize such data and establish exchange rules, the international organization Open Geospatial Consortium (OGC) was established. From its inception to the present day, OGC has been the leading institution that defines international standards for the creation, exchange and use of spatial data at the global level.

OGC standards encourage the development of spatial data services and direct the entire community to the use of spatial information and web services in a variety of desktop and web applications, as well as to the development thereof.

Currently there are more than 30 defined standards within the OGC standardization, of which Web Map Service and Web Feature Service are most commonly used to share data over the Internet. In the next period, within the National Geospatial Data Infrastructure, it is planned to establish a functional system that will enable the exchange of spatial data at the state level using these standards.

Web Map Service (WMS) provides a simple HTTP interface for requesting geo-registered map images from one or more distributed geospatial databases. A WMS request defines the geographic layer(s) and area of interest to be processed. The response to the request is one or more geo-registered map images (returned as JPEG, PNG, etc) that can be displayed in a browser application. The interface also supports the ability to specify whether the returned images should be transparent so that layers from multiple servers can be combined or not.

Web Feature Service (WFS) represents a change in the way geographic information is created, modified and exchanged on the Internet. Rather than sharing geographic information at the file level using File Transfer Protocol (FTP), for example, the WFS offers direct fine-grained access to geographic information at the feature and feature property level. This International Standard specifies discovery operations, query operations, locking operations, transaction operations and operations to manage stored, parameterized query expressions.

Web Map Tile Service (WMTS)is the fastest way to achieve the availability and scalability of previously created georeferenced thumbnails, which does not require the processing or exploitation of the properties of these thumbnails. It is most commonly used to transmit data that is collected at specific periods and for which there is no need for frequency updates, such as satellite or aerial orthophotos.
