Geospatial Models

Geospatial models are the basic concept of the Geographic Informaton Systems. For this technology to work, it needs quality and correctly structured data. To make a good GIS model is not so simple as it seems. It needs design and build of the structure of the layers, attribute design, data creation, validation and spatial topology, quality design and evaluation of the interoperability. Things that we manage very well.

Bitmap has developed different precision and detailed models for the territory of Bulgaria. Often our customers don't have the needed basic information and on us to integrate that information to their GIS data.

Models for the country that we have and offer are:

  • Administrative borders - settlements borders, territories, municipalities, counties and the state border. Especially for urban planning we have a model of urban areas with accurate and current borders of the territories occupied by buildings;

  • Digital model of the relief - DEM model, contour lines, elevations and special formations, relief models that are integrated with the local LIDAR surveys, vertical planning and many others. We also support an integration of geodesic surveys in DEM model - bridges, dikes, embankments and ditches, road sections and intersections and many others;

  • Soil information - soil profiles and soil distribution - types and differences, soil maps, integrated and georefferenced physiochemical and biological analyses of soil examples etc.;

  • Geology and Geomorphology - geological groups and entities linear fault structures and others;

  • Surface and underground water - springs, rivers, lakes, dams and reservoirs, groundwater bodies and hydrogeology;

  • Road network - we have excellent 2D and 3D models of the whole county road network -  republican country road network, also local roads, streets and special objects (like alleys, squares and routes). The whole model includes attributes of the roads that are needed for the design of the transport models and analyses like line referencing;

  • Settlements GIS - quarters, streets, buildings (functional purpose, number of floors, underground, etc.), administrative addresses, over and underground lines, shafts, channels and other special objects;

  • Population database - model of population in cities and villages, tied spatially and broken down by sex and age;

  • Protected Areas - borders of national parks, protected areas and natural attractions, Natura 2000 sites;

  • Biodiversity - forests and lands with high natural value, distribution of rare and endangered species, sensitive areas, wetlands and areas with high conservation value, and many others;

  • Climate and weather measurements - we have developed in 2015 maybe the first GIS model in Bulgaria for the climate zones. The model includes multiannual measurements from over 200 climate stations across the country and also data for all main groups climatic parameters - air temperature and soil, rain, sun and wind;
