Training video material on forming the Map Atlas in the GIS "Panorama" is prepared

27.03.2018

Specialists of KB "Panorama" prepared the video lesson of forming the Map atlas in the GIS "Panorama". The information basis of any geographic information system is the spatial data, which are classified by content, scale, purpose and territoriality. When working with cartographic data onto large areas, it becomes necessary to display information in an overview and with detailed textures. Combining all spatial data in one map leads to an increase in the time for searching for objects, performing the computational and analytical tasks. In order to speed up the processing of information, it is recommended to structure the data using the Map Atlas task.

The map atlas is a systematic collection of spatial data and is designed to simplify the transition between overlapping data of different scale. The training film shows the technology of forming the Atlas of maps using the example of the Russian Federation's base map of scale 1: 1 000 000 and maps of subjects of the Russian Federation of scale 1: 25 000.

The digital thematic (geographical) map of Russia on the scale of 1: 1 000 000 provides an overview of the country territory, but its composition does not provide detailed data on the subjects of the Russian Federation. Free maps based on OpenStreetMap data of scale 1: 25 000 contain detailed information on the objects of the terrain.

When combining spatial data in the Map Atlas, the operator sets the visibility ranges (displaying) for each set and determines their numerical composition, which allows to exclude unused data. The transition is performed using the geodetic coordinates of the cursor or the center of the active window. The map atlas is presented as a tree of a group of projects. The group of projects includes various types of data - vector, raster and matrix maps, as well as map projects (MPT).
