GIS WebServer SE extends the functionality of geoportals by means of the user modules

13.11.2018

In KB "Panorama" the GIS WebServer SE version 4.3 is developed. In the new version the ability to connect the user's controls is added. User's controls are modules developed in PHP and JavaScript and used in GIS WebServer SE to expand its capabilities. Connection and development of modules is carried out through API interface the GIS WebServer SE. Like the standard components of the map, the modules are included in the maps projects and are used in the work. The program optimized the display of a cloud of points and line primitives in tile models. The positioning the model of 3D tiles is carried out taking into account height of a point of a tile binding. To speed up the display of the three-dimensional model, caching of auxiliary tiles has been added. In the "Map Editor" a mode for editing the metric part has been developed. Parameters of editing the metric are expanded: there are added a capture of points and capture of lines (a point on a line within capture radius).

In a map the ability to set its maximum dimensions is realised. The operations of moving the map, searching and selecting objects are performed within the established dimensions of the map. Into local layers of a map the display of titles for point objects is added. The text of the title can be output from the local layer classifier file, the geojson file, or set by default parameters. Loading the classifiers of map layers is optimized. The interface of the map user is updated. In the administration module the registration and setting up rights onto user's controls is added.

The toolkit of developing the Web-applications the GIS WebToolKit SE has been improved, which expands possibilities of GIS WebServer SE and can be integrated into other information systems. Access to data (images, vector maps and terrain information) is provided by Web services using common OGC protocols and ISO standards. Service of GIS WebService SE (OGC WMS/WMTS) provides spatial information in the form of graphic images. Various types of high-altitude data are used as a digital elevation model: matrixes (in the formats SRTM, GeoTIFF, IMG, MTW), TIN-models, point cloud and others. At request the most accurate data onto a specified terrain site with a given resolution is automatically sampled. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data is represented as tiles and cached on the client.

As a source of spatial data, the Databank of digital maps and remote sensing data can be. It provides the collection, storage, search and delivery of spatial data in exchange formats, a displaying the state of the data bank in the form of maps-schemes, the automated formation and updating of geo-covers.

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.

The new version of the program is available on the website in the Download section.
