GIS WebServer SE displays interactive model of the globe with the star map

29.08.2017

GIS WebServer SE version 3.4 is developed in KB "Panorama". In the new version of the program at displaying spherical model of the Earth the map of stars with constellations and the Sun is shown. When you change the location, the map in real time calculates the current position of each star and planet seen from Earth, taking into account the current date and time of day. The star map displays 5024 stars and 88 constellations.

There is added a possibility of cyclic displaying and moving of the two-dimensional image of a map along a longitude, similar to the rotation of the globe. When solving various navigational tasks, the map allows you to view continents, cities, countries, analyze their relative location, regardless of the standard range of longitude В± 180?.

The system of measurements on the map is updated. In the mode of measuring the path length the calculation of orthodromic distances is added. The calculated lines of orthodrome are drawn on the map. The tool of clustering objects markers is refined. Object markers are clustered according to the criterion of their distance from each other. When zooming out, markers are merged into clusters. The number on the cluster indicates the number of markers in it. When you click on the icon, the scale of the map is increased, the cluster is split into separate labels of objects and clusters. Data of objects for clustering is described in GeoJSON format. You can customize the appearance of clustering icons.

In the administration module the use of domain groups and users is simplified at customization of access rights. At change of the list of groups or users of the domain a recustomizing of access rights for them in the application is not required.

The web applications development tool the GIS WebToolKit SE has been refined, which extends the capabilities 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 GIS WebService SE (OGC WMS/WMTS) provides spatial information in the form of graphic images. As digital model of a relief the various kinds of high-altitude data are used: matrixes (in formats SRTM, GeoTIFF, IMG, MTW), TIN-models, a cloud of points and others. At request there is carried out the automatic sample of the most accurate data onto the specified terrain site with a given resolution. To transfer data of the digital terrain model to the Web, the WCS protocol is used. The relief data are represented as tiles and are cached on the client.

As a source of spatial data, the Data bank 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, documentation and presentation are available on the web-site in the Download section.
