The third military survey� The second military survey became obsolete. It was never finished, the survey

methods became out of date.

� 1869 start of the 3. military survey.

� The survey was based on the new

triangulation and new levelling networks

� The use of 1 : 25 000 maps

� Achievement: 746 sheets, 1 : 75 000 scale

� 1899 – the end of the 3. military survey.

• The result :

• Use of metric system

• Military topographic maps in the scale of 1:25 000

• 1353 maps , size of maps 76 × 55 cm, area depicted/map 261 km².

• Hydrogeology, elevation

The new survey of Budapest

• 1932, start of survey

• New triangulation network

• Strict survey methods (every point is measured in the field and gets coordinates)

• Numerical survey methods

• 1:1000 scale

• After WW II. the work continues. Budapest grows in size due to new districts. Changes in organization and technology alter the work.

High accuracy survey plan

• Since 1975 surveying and mapping was implemented in the Uniform National Projection (EOV) and the maps where produced in the Uniform National Map System (EOTR).

• Scale of maps - 1 : 4000 , towns and cities 1:1000, 1: 2000

• Map grid covers the whole country, but the EOV new mapping was never finished.

• Old maps created in earlier projections :

– projection without reduction,

– Budapest Stereographic Projection 1860 and

– three cylinder (HÉR, HKR, HDR) projections 1908 .

Description of EOV Projection System• Name: EOV (Uniform National Projection System).

• Description: The EOV is a plane projection system used uniformly for the Hungarian civilian base maps and, in general, for spatial informatics. (Base maps: 1:1000, 1:2000, 1:4000 large scale maps for cadastre and 1:10.000, 1:25.000, 1:100.000 topographic maps.) 1: 10 000 overview maps

• Geometric classification: Conformal cylindrical projection in transversal position.

• Date of introduction: 1972-1975

• Origin of EOV plane coordinates:Coordinate system is moved to South-West with respect to origin of projection so that all possible EOV coordinates be positive for Hungary:

• XEOV = x + 200 000.000 mYEOV = y + 650 000.000 m

18

Main parameters of EOV projection system

• Parameters:

• Reference surface:

The IUGG GRS 1967 reference ellipsoid (Geodetic Reference System of International Union of Geodesy and Geophysics, 1967):

a = 6 378 160.000 mb = 6 356 774.516 m

Ellipsoidal geographic coordinates: ,

• Projecting sphere:

A Gauss-sphere fitted to reference ellipsoid at the normal parallel.It is used for Gauss-sphere:

its radius: R = 6 379 743.001 m

and its spherical geographic coordinates: ,

DAT Regulation

The Digital Base Map (DAT) Regulation provides detailed descriptions of the procedures of design, production, revision and maintenance of digital base maps ,about their data exchange format, documentation, control, quality control, verification and State acceptance, also the conversion of numeric and digital data of land surveying base maps into digital base maps and their quality control.

From 1996 on, it is mandatory to produce the national land surveying base maps .The DAT Regulation consists of the following parts:• DAT1 Regulation: Design, production, revision and maintenance of digital base

maps, their data exchange format, documentation, control, quality control, verification and State acceptance.

• DAT2 Regulation: Conversion of land surveying base maps into digital base maps and their quality control.

• DAT1-M1: Annex to DAT1. Structure, data tables and data exchange formats; DAT1-M2: Annex to DAT1. Legends of the digital base map.

• DAT1-M3: Annex to DAT1. Land office software for examining and verifying the internal consistence of digital base map data.

• DAT2-M1: Annex to DAT2. Starting data and a computation software (TRAFO)for transformation among projection systems applied in Hungary (STG, HÉR, HKR, HDR, EOV, BOV) based on unified requirements and accuracy.

The rank of obect points (detail points) • R1: The main breakpoints of administrative boarder’s with strict stationary

markings, all urban land parcel points bordering public lands (streets and squares)

• R2: Additional points of administrative boarders and urban parcels. Rural land parcels’ well marked points.

• R3: Rural parcels’ additional points, and the points of buildings, roads, cables’ and pipes’ surface facilities.

• R4: Points not belonging to the upper categories: ditches, cultivation type boundaries,

• R5: A soil quality boarders and geocode points.

National Cadastre Program

Progress of the program:

Digital new surveys June 2002

Revision of the National Cadastre Program

• Too slow and expensive, not enough result- by the end of 2003: the maps of 80 settlements are ready- IT infrastructure of land offices is well-developed- introduced digital map standards (DAT)

• Urgent need for digital maps• 2003: Revision of the program – speed up

important to continue, more financial support is needed� 65,6 million EUR loan is used until the end of 2007

• Decision: digitizing the existing paper cadastral maps2005: maps of rural areas, 2007: maps of urban areas

• All cadastral maps of Hungary converted into digital form byDecember 31, 2007.

Evaluation: Digitizing original paper mapsAdvantages:

The most cost-effective way for making DAT maps (databases)This method were used as a composite method with new surveyingThe boundaries of a block of cadastral parcels were demarcated and

surveyed, but the inner part of the block digitizedThis method can be used in the case of blocks, where changes of

boundaries are not highDisadvantages:

Conditions of original paper maps were sometimes very poor (distortions, pollutions, coffee etc.)

Output of digitization is a spaghetti vector map, not an object-oriented database

Original paper maps are legally valid, but sometimes do not reflect the real situation (e.g. land use)

Transformation between different projections (and datum) could effect inconsistency between data. (5 different projection systems)

36

Problems with digitized old mapsConditions of original paper maps were sometimes very poor: distortions,

Original paper maps are legally valid, but sometimes do not reflect the real situation, the real land use and the new buildings.

37

Results

38

New Surveying

• 10 % (~ 1 million ha) of Hungary was surveyed

• Output: Object-oriented databases according to Digital Base Map Standard

• Costs: EUR 23,2 million

Digitization

• The rest (90 %, ~ 8,3 million ha) was digitized

• Output: Spaghetti Digital Cadastral Maps

• Costs: EUR 34,5 million

Costs are highly different between rural and built-up areas of settlement

Neto income from selling maps and digital data
