Geometria GIS Systems House Ltd.

Company Profile

Geometria GIS Systems House was founded in 1986 as an independent private company to develop and supply Geographic Information Systems. Geometria is the GIS market leader in Hungary. Apart from its domestic business over 40% of the company's production are exported, mainly to EU countries. The company is extending its activities steadily.

Geometria's activities are characterised by the following:

The company's activity is the combination of the engineer's thinking fused with state of the art technology, information technology.

Geometria has 115 employees out of which 35 perform system developing and 60 data capturing. 60% of its employees have high degree qualification connected with their activities.

Geometria's services include:

Application Software Development

A team of Intergraph software experts creates utility network management systems. Geometria is an Intergraph Solution Centre and an Intergraph Independent Software Developer. There are Intergraph Registered Consultants in-house for MicroStation, FRAMME & GIS Mapping (MGE). References include electric, water supply and telecommunications projects both under FRAMME and MicroStation MDL.

GIS Software Development

Geometria developed topoLogic 2.1 GIS software which is a vector GIS system and function library with built-in digital terrain modelling for Microsoft Windows and UNIX.

Map Data Conversion

Over 60 professionals convert maps with manual, semi-automatic and automatic procedures including attributing, pre-processing and plotting. All these processes undergo rigorous quality control tests. Service includes customer specific technology development and rulebase to exclude erroneous data already in the input phase. References include the German Road network for car navigation purposes, the National GIS Database of Hungary and the 1:10.000 topographic sheets of The Netherlands. Geometria has special expertise in road database creation for car navigation purposes, facility management for utilities, topographic and geographic map data conversion and remote sensing editing.

Regarding to the application fields Geometria pays special discriminated attention to the quality of its services. In the frame of an international co-operation - the COPERNICUS project of the European Union - Geometria is currently introducing the ISO 9000 quality assurance standard. This effort is based on the successful Esprit Bootstrap project.

Significant project and references

Low-voltage Information System (KIR)
High-voltage Information System (KÖFIR)


The KIR (Low-voltage Information System), characterised by electric and geometric topology, contains elements of both the transmission (0.4 kV) and the public lighting networks from transformer stations to customers' connections and from street lamp switches to lamp locations, respectively.
The High-voltage Information System (KÖFIR) contains the elements of the high-voltage (10, 20 and 35 kV) network with electric and geometric topology from the substations to the transformer stations including the schema of the transformers.

Network Information System (HÁLIR)


The HÁLIR, the Network Information System of the Budapest Water Supply registers the water system (from the production wells to the customers) of the capital and its outskirts on 1:4000 and 1:50 000 scale digital maps. Beyond the registration it also helps modeling and designing pressure zones.

1:200 000 Scaled Digital Road Network of Austria


Geometria GIS Systems House Ltd. completed the digital road network map of 6 states (Vorarlberg, Tirol, Karnten, Salzburg, Steyermark, Oberösterreich) of Austria at the beginning of 1994. The project which was performed on behalf of the AGIS Ges. m.b.H. covered 80 of the area of the country.

Budapest District Heating Network Information System (HőTÉR)


The HőTÉR is the map-based technical registration system of the Budapest District Heating Company being realised in multi-user environment and client-server architecture. The system registers the primary and secondary district heating network of the capital from the heat-generators to the consumer's buildings. HőTÉR is being developed as a part of the integrated company information system connected with the technical base-registration, controlling and document management subsystems of the Budapest District Heating Company.

German Road Network


Digitising and attributing of road network maps of Germany at the scale of 1:25000 for using by on-board car navigation systems
European Geographic Technologies (EGT) develops and markets a pan-European digital geographic database for a wide spectrum of GIS based applications. Main application is the set-up of a vehicle navigation system for commercial use. Geometria produces the database by pre-processing, digitising and attributing data from 1: 25.000 scaled topographic maps.

Austrian Digital Forestry Database


Digitising and attributing colour models from ortophoto images
The Austrian State Forestry (ÖBF) is in the process of a ten years program to set up its own digital database for state forests. Geometria delivers 64.000 hectare digital data set in the project with digitisation.

Elevation Database of the Netherlands


Digitising and attributing of spot heights and contour lines of the Netherlands (scale 1:10.000)
During the project all spot heights of The Netherlands have been converted according to strict quality criteria. For the purpose of quality it was necessary to prepare the digital terrain model (DTM) of the maps.

Satellite-image Classification of German States


Data providing by satellite-image classification for planning a mobile telephone-system in Germany.
During this project Geometria had to distinguish some special objects that could influence the function of a mobile telephone-system. The precise places of these objects have special importance for planning. During the process satellite-images were compared with the topographical maps and the data for planning were updated.

Data Input of 1: 10.000 scaled topographic maps of The Netherlands


On screen digitising of planimetric data from the 1: 10.000 scaled topographic maps.
