Input data and its providersGeonet 2000 Ltd.
MTA-TAKI

• Cadastral raster maps
• Topographic raster maps
• Numbers in cadastral survey
• Vector based map with contour lines
• Ownership certificates of registry of title deeds
• Basic topography (public administration borders,
  hydrography, road network, etc.)

• Digital terrain model
• Digital terrain model for exposition
• Digital terrain model for gradient of percentages
• Soil profile data
• Soil area data (physical, chemical, genetical,
  nitrate sensitivity, agricultural suitability)

Close collaboration with MTA TAKI Data
collection system

• The system is based on
• GPS technology,
• Windows CE OS (Pocket PC, Handheld PC, etc.),
• Autodesk OnSite View
• Vector maps (EOV Uniform Country-wide
  Projection system)
• Used for collecting various soil data

Local GI data infrastructure system requirements

• Local GI data infrastructure system for a
  demonstration area Balatonlelle, Balatonszemes,
  Gamás, Látrány, Somogybabod, Somogytúr, Visz
• Integration of raster and vector data
• Web based
• Unlimited number of users
• Easy to learn user interface
• OS independent at client side

Integration of raster maps

• Transformation into GeoTiff (geographical raster
  image) and raster image catalogue
• Result
• Autodesk MapGuide displays raster maps under
  suitable map scale depending on the zoomed map
  slice

8
Usage of numbers in cadastral survey

• As identifier of records in registry of title
  deeds database
• They appear as digitized data on raster maps on a
  dedicated layer
• They appear automatically if the map scale is
  less than 10000 m

9
Soil profile reports

• On site descriptions
• Data of on site analysis
• Data of laboratory analysis
• Data of nutritive matereial analysis

10
Soil area reports

• Physical soil area data
• Chemical soil area data
• Data of nitrate sensitivity
• Genetic soil area data
• Data of agricultural suitability
