Digital Maps

During the last number of years, our company produced a premium quality (accurate for scale 1:10000 or higher) digital map database of Hungary. Its data layers were built into, -and are currently used in various transportation IT and other GIS projects, including in our ÚtInfó navigation product. These map layers undergo scheduled, yearly updates, so that data freshness can be ensured.

We offer to interested parties the following data layers, covering Hungary:

1. Road network sections/intersections
2. Address
3. Land parcels
4. Parcel numbers
5. Railways

Map layers can be ordered separately, or in custom bundles. Data can be provided for local (by settlement), or larger (regions, counties, etc.) administrative boundaries coverage, including for the whole country.

1. Road network sections/intersections

These two map data layers make up the national, street-level road network map, which was created by CData-Térképár Ltd. between 1998 and 2009. Our company executes its yearly updating, using legally validated GPS technology. It also performs a yearly data maintenance using Magyar Közút Nonprofit Zrt. (Hungarian Public Roads Non-profit Authority)’s official database.

We ensure accuracy, completeness and up-to-datedness, by also referencing our data with 4-5 other data sources. Whenever possible, we employ as reference orthorectified aerial photography and satellite imagery. Attributes of the road network sections/intersections layers are populated with an automated method, using our self-developed algorithms, followed by a manual completion, refinement and detailed quality control.

In populated areas, the name and type of public places corresponds with those specified by the KEK KH (the Central Office for Administrative and Electronic Public Services). This national road network data includes all state and local government owned municipal and rural roads, together with most forestry and other, privately owned and maintained roads.
Data format: MapInfo TAB and ESRI SHP. Projection system: data are stored in EOV and WGS84 coordinate systems. If needed, we can provide data in any other formats and projections.

- The road sections dataset includes polyline objects symbolizing road centrelines.
- The road intersections dataset includes point symbol objects, denoting the intersection points of roads. Alas, a section is the polyline connecting two neighbouring, consecutive intersections.
- Within a map, there is exactly one intersection at each end of a section.
- Every single section’s end-node matches the end-node of the next, connecting section, so that there aren’t any breaks in the road network.

Note: on the actual map, the intersection layer will not be displayed, being only an auxiliary layer.

Attribute structure of the road section layer

Country Code: Integer number, consisting in the country’s identifying code. Hungary’s code is 1.

Map Code: Integer number, consisting in the map section’s identifying code. There are 42 map sections, featuring map codes from 11 to 52.

KSH Code: Integer number, consisting in the settlement’s KSH (Hungarian Central Statistical Office) –given identification code, made up of 3 or 4 figures.

Settlement-part Code: Integer number, representing the settlement-part’s identification code.

Section Code: Integer number, representing the section’s identification code, unique within a map section.

Street Code: Integer number. Sections making up a street are assigned the same street code. Default value is 9999 (i.e. if the street has no name).

National Code: Integer number, representing the individual section’s code on the national road sections layer (currently not used = 0)

International Code: Integer number, representing the individual section’s code on the international road sections layer (currently not used = 0)

Road Type: Integer number, representing the road’s type (i.e. motorway, local main highway, etc.), from 1 to 20*

Intersection 1: Integer number, representing the identification of the intersection point at one end of a given road section (graphically, at its beginning)

Intersection 2: Integer number, representing the identification of the intersection point at the other end of a given road section (graphically, at its end)

Local Name: Character (128), text, the street name and public place, used within settlement boundaries (i.e. “Hajdú utca”- a street, or “Hunyadi tér”, a square)

National Name: Character (32), text, the national reference naming (if exists) of the route section (i.e. "M3" or "33")

International Name: Character (32), text, the international reference naming (if exists) of the route section (i.e. "E71")

Level Lift Marker: Integer number, used for sections belonging to a lower, not national type route, which we want to elevate to be part of a higher type, national or international route ( 0= no lift, 1=lift to national level, 2=lift to international level)

Transit: Integer number, referring to whether the section is part of a transit route (0=no, 1=yes)

One-way: Integer number, (0=no, meaning two-way, 1=one-way towards intersection 1, 2=one-way towards intersection 2)

Divided road: Integer number, (0=no, 1=dividing line, 2=physical dividing obstacle between the road’s two ways)

Roundabout traffic: Small integer number, (0=n0, 1=yes, 2=yes, the section is part of a roundabout, but there is no exit from it)

Length: Decimal (10,1) number, referring to the section’s length, in meters

Explanation of Road Type annotations:

1. Freeway, motorway
2. Semi-motorway, highway
3. National 1 digit highway
4. National 2 digit highway
5. National 3 digit highway
6. National 4 and 5 digit highway
7. Local main road (within a town, this road is marked with a main road traffic sign, which is not leaving the town)
8. National down-/up-ramp
9. Local down-/up-ramp
10. Other auto vehicle roads (paved)
11. Unpaved (dirt-) road
12. Pedestrian causeway (can be accessed by cars)
13. Pedestrian causeway (cannot be accessed by cars – too narrow)
14. Pedestrian causeway (cannot be accessed by cars –stairway)
15. Pedestrian causeway (cannot be accessed by cars –sidewalk, pathway)
16. Bicycle road
17. Hiking road
18. – Not used
19. – Not used
20. Ferry (needed for national referencing, as well)

Attribute structure of the intersection layer:

Country Code: Integer number, consisting in the country’s identifying code. Hungary’s code is 1

Map Code: Integer number, consisting in the map section’s identifying code. There are 42 map sections, featuring map codes from 11 to 52.

KSH Code: Integer number, consisting in the settlement’s KSH (Hungarian Central Statistical Office) –given identification code, made up of 3 or 4 figures **

Settlement-part Code: Integer number, representing the settlement-part’s identification code.

Intersection Code: Integer number, representing the intersection’s identifying code, unique within each map. ***

X: Float number, representing the intersection’s coordinate X, in EOV projection.

Y: Float number, representing the intersection’s coordinate Y, in EOV projection.

Crossway Vehicle Indicator: Integer number, not used.
Crossway Pedestrian Indicator: Integer number, not used.
Outburst Point: Integer number, not used.

** - In case that the intersection is right on a boundary of some sort, and it represents the crossing point between the two areas, then the following values can be assigned:

2 = within a map, for the intersection situated on a settlement boundary.

3 = at the map boundary, for the intersection situated on one of the 42 maps’ borders.

4 = for intersections situated on the national borderline.
For every other intersection, within the area identified by the common KSH code, the value is 1.
