What is MapGen?

MapGen is a set of spatial data management models that allow the users to automate the generalization of spatial data from a larger scale to a smaller one and to automatically create a standardized map from generalized spatial data. MapGen generalization models runs in ESRI software's ArcGIS Desktop environment.


The logic of the MapGen product spatial data model and its structure are based on DIGEST standard and the Multinational Geospatial Co-production Program (MGCP) spatial data model. The spatial data model consists of objects of different categories: hydrographic objects, transport network objects, buildings, land cover objects, relief, boundary objects and objects represented by point elements.






Lakes, reservoirs, ponds, rivers, streams, canals, ditches, lagoons, seas, etc.

Transport network

Roads, railways, tracks, bridges, viaducts, etc.


Various purpose buildings

Land cover

Forests, crop land, wetlands, sand dunes, peat bogs, quarries, built-up areas, gardens


Contour lines, height points, etc.


Administrative boundaries, boundaries of protected sites, other boundaries

Objects represented by point elements

Survey points, towers, chimneys, wind turbines, monuments and structures are not expressed in area objects, etc.

MapGen Mod

MapGen100 is a modification of the MapGen product whose models are designed to automate process of generating spatial data set and maps at the scale 1:100.000 using source data at scale 1:25.000 - 1:50.000.


MapGen100 spatial data processing models are divided into two main parts - spatial data set generalization models and cartographic view creation models. All models have a user interface that clearly sets out the order of the data to be selected. The user interface describes what initial data should be selected in the model. As a result of the operation of MapGen100 spatial data preparation models, the generalized geodatabase GDB100 is prepared, accordingly as a result of the operation of MapGen100 cartographic data preparation models, the generalized cartographic data Carto100 and MapGen standard map at scale 1:100000 is prepared.


Before using the MapGen models, the user must prepare initial data in accordance with the MapGen data specification requirements, i.e. transform the original data into a MapGen spatial data structure. Of course, Via GIS can always advise and help customers prepare their initial data properly and transform them smoothly into the required data structure.

The MapGen100 has initial spatial data validation models that check whether the transformed initial data corresponds to the MapGen spatial data structure and whether it is suitable for automated generalization to smaller scale spatial data. Verification models check the geometry and attributes of the source spatial data. Based on the results of the verification, the user may adjust its initial data.


MapGen100 spatial data processing models are divided into two parts: spatial data set generalization models and cartographic representation creation models.


MapGen100 spatial data set generalization models are designed to automatically process initial data to obtain a spatial data set at scale 1: 100000. The tools automatically simplify spatial data, merge neighboring or eliminate redundant objects, reduce the number of object vertices, and so on.


Cartographic representation models are designed to automate cartographic data generalization and create a standard digital MapGen map at scale 1: 100000. Objects are assigned cartographic symbols, and they are represented according to cartographic rules. Before running cartographic generalization models, cartographic data is transformed, then symbols are assigned to objects, and cartographic generalization is performed.


At the end of the workflow of the MapGen100 models, the user gets automatically generalized spatial data and cartographic datasets that meets the data completeness criteria at scale 1:100000 and creates a standardized map in pdf format.

Advantages and benefits of MapGen


The great advantage of MapGen's product is its simple adaptability to the specific needs of the customer, taking into account the structure of the initial data and the desired end result, the customers experience of spatial data management automation, customers current versions of ArcGIS licenses and other indicators.


With easy-to-use MapGen models, the customer gets a complete spatial data generalization technology solution that helps to create new or updated spatial data and cartographic products very efficiently.

  • Spatial data creation and map editing requires less staff compared to the classic - manual method.
  • Only one scale initial data set needs be up-to-date and other data generated in an automated way.
  • Less hardware and fewer software licenses are required.
  • Significantly shorter time to create spatial data sets and maps.
  • Fast updating of spatial data and maps.
  • Spatial data that is always actual.
  • The solution operates in a well-known and popular ArcGIS environment.
  • Simple licensing terms.
  • Possibility to modify the solution, adapt it to specific needs.

Technical requirements


MapGen requires ESRI ArcGIS Desktop Advanced software. Most MapGen models runs with Standard type licenses, but some models require Advanced functionality ArcGIS licenses.


It is recommended to use PCs with Windows 10 Pro or Enterprise (64 bit) operating system to work with MapGen models. The hardware configuration depends on the amount of spatial data you want to process.


For efficient work with data, it is recommended to use personal computers with: Intel Core i9-9900K 10 cores processor; main memory RAM 32GB; disk drive 512GB SSD; disk storage for data archive - on demand.
