The structure of vector maps allows to store not only the digital description of real objects of district, but also the applied user data that can quickly vary in time.

For example, weather forecast, data on move of vehicles, data about conditions of radio visibility and so on.

For storage of these data together with a map it is enough to expand only lists of layers, object types and their characteristics in the digital classifier. However, such approach has following defects:

- user objects located on several sheets of a map, at writing down will be divided on the sheets that complicates their further processing;

- data, put onto the one map, cannot simultaneously be displayed and edited on other maps of the same territory;

- it is necessary to expand and accompany some digital classifiers for different types and scales of maps.

Therefore the Map 2011 system allows to store the user data separately from maps of district, using a subset of structure of vector maps.

User vector map consists only of one map sheet, which has no constant sizes. At addition or deleting of objects its dimensions and an arrangement will vary. The user map can be displayed together with a vector map of region, and also with raster and matrix maps. The same user map can simultaneously be displayed on different maps of region and be edited by different users. Results of editing at different users will be looked equally.

The user map has the own classifier, which does not depend on the classifier of a map.

Together with one map of region any quantity of various user maps with their own classifiers can simultaneously be displayed.

Creation, updating and distribution of region maps and the user maps can be carried out independently by different services from different sources.

The exchange of the user maps can be carried out in SXF format of a binary or text kind.

Objects of the user map can have no link with the user classifier. Graphic representation of object can be stored in record of object that facilitates converting data from formats: DXF, MIF/MID, etc. Attributive data can be stored in an external relational database. Link with a database is carried out by unique number of object on a map.

To understand what it is a user map, imagine a pasting of paper maps, on which from above have put a page of a tracing plan. On this tracing plan it is possible to transfer objects from the map passing from one page to another. On a tracing plan they will be plotted as a unit. Besides it is possible simply to draw on it the abstracted figure, not changing a map. Then this tracing plan can be imposed on other map and to transfer on it site removed from the previous map. The user map is something similar, with that difference, that at a location it on a map of other scale it is automatically compressed or stretched.
