In the paper, a new version of Mapan software serving in exploitation of digital forest maps (DFM) is presented. The software is adapted to the requirements of DFM Standard introduced by the Regulation 74/2001 of the Director General of the State Forests. Each function of the Mapan software may be assigned to one of four categories: 1) data sources management, 2) reporting, 3) edition, 4) auxiliary operations. Within the category of data sources management the issues discussed are as follows: a) selection of the mode of link to the database Information System of the State Forests (direct, work on a copy of the base, work without link) and their working possibilities, advantages and disadvantages of each mode of link; b) configuration of the software, including setting and control of parameters; c) layer catalogue and its functions; d) layer manager and its functions. Within the category of reporting three groups of reports are discussed: a) selection (by object designation; by address; by queries concerning: taxation description, plans, timber; by SQL queries), b) descriptive information (tabular reports, lists, descriptions and other) for objects and exclusions, c) thematic maps (economic types of tree stands; tree stands; habitat; division of forest districts, communes, counties, reporting ranges; industrial threat zones; hunting districts; protected forests; economic seed stands; reserve protection zones). Within the category of edition possibilities of editing layers and descriptive information are discussed as well as a possibility to create and edit own layers to include them into the information system, which are not provided for in the DFM Standard Within the category of auxiliary operations typical operations are distinguished connected with maps and a number of useful operations, e.g. showing kilometers grid, highlighting selected elements, length and area measurements, developed fire-fighting application, print preview with possibility of smooth change of the scale and setting of other parameters. In elaboration of the new version of the Mapan software attention was paid to the user.s work comfort, and to fast and easy access to data. In view of the needs of foresters, options for data presentation were expanded. Taking into account multiple functions of the software, its proper assessment may take place only after its sufficiently long exploitation.
