GIS WebServer SE is used in the construction of closed corporate systems to ensure the protection of data having a security classification or a trade secret. GIS WebServer SE is certified for Level 2 of absence of undeclared capabilities. The new version of the program expands the application's capabilities in solving problems of analysis, management and long-term planning of the territories development. GIS WebServer SE is implemented using the toolkit of GIS WebToolKit SE, which can be used in development tools that use the JavaScript.

In KB "Panorama" the training materials have been prepared for developers of web-components in the
Web-components can be of two types. The first type processes data on the client without accessing external services. For example, calculation of the area and length of object by its coordinates in the GeoJSON format, received on WFS-request from another component. Such component is implemented as JavaScript on the client. Another type of component requires interaction with a web service to process large amounts of spatial data located on the server and available for reading and updating by many users simultaneously.
For example, the server hosts matrix and vector geo-covers with relief over large areas. It is necessary to determine the height of a point by its coordinates on the ground. GIS WebService SE can use the functions of the MAPAPI interface, which provide automatic analysis of data available at a given point, selection of a source with the highest accuracy to determine the height at a point, performing geodetic calculations and interpolation of values by the surrounding objects. To take advantage of these tools, a new REST request is added into the web service on the basis of a set of SDK libraries written in C ++. SDK GIS WebServiсe SE automates analysis of request parametres, loads library and a method for its processing, provides access to the spatial layers published on service, and forms the service response (xml, json and others). On the web client side in JavaScript, input of request parametres and displaying the result are implemented.
The updated documentation uses examples to show how to add a new request to the GIS WebService SE and call it from the
In the first example, a button is added into the control panel to invoke the panel "Get Geo-Coverage value at a point". When you select a point on the map, the height value of the specified point is displayed in the table. Data exchange is performed via the GetCoveragePoint REST request added into the GIS WebService SE. The request is processed by a custom library written in C ++ and connected to the service.
In the second example, a button is added to the control panel to invoke the panel "Building a heat map". On the panel the parameters of for building a heat map are set. Clicking on the "Build" button will display the heat map as a separate layer. Building a heat map is performed on the server using the BuildHeatMap REST request. The lifetime of the layer is determined by the request parameters or the service settings.
GIS WebService SE supports all international standards (OGC WFS, WFS-T, WMS, WMTS, WCS), which are used to transfer and display spatial data. The program implements the ability to issue tiles in a user or standard coordinate system. The application is implemented on Windows and Linux platforms and is compatible with Apache, IIS and nginx web servers.
Training materials are available on the website in the Documentation section.
The geoportal
The map was led to the modernised classifier of large-scale plans of scale 1: 5 000 (map5000m.rsc). Publishing of updates in bank of spatial data is made by using the program of Databank of digital maps and remote sensing data. Publishing contents of bank of spatial data on the geoportal and data access for downloading are implemented by means of GIS WebServer SE.
