A L K I S / A T K I Snew

• integrated Data Modelling:• Standardized notation, international norms

• Semantic harmonization of cadastral and topographic information

• Integration of metadata

• ALKIS enable to manage historical data

• possibility of integration of cadastral and mapping data (vertical integration of data)

derivation

integrated actualization of independent data sources

The general approach


Remarks• Collected data will be used on both the cadastral level

and the surveying and mapping level. This "vertical integration" is the first step to the general approach that data should only be collected once and should be used for different scales.

• The general approach of the vertical integration of data can be attained if the task of cartographic generalization is solved. Over the next few years, research will focus on this subject. This will open the chance to reorganize Spatial Information Management.

The use of geodata in Northrhine-

Westfalia and Germany

Building up a Geodata Infrastructure in Northrhine - Westfalia (GDI NRW)

Exploitation of and access to public geospatial data using standards and

modern technologies in Northrhine - Westfalia, Germany


Geodata Infrastructure NRW• Started in June 1999 by the minister

president of Northrhine - Westfalia Exact knowledge about market potential Integration of core data and special geodata Supply of user friendly information products Open network for geodata Legal conditions regarding the access to official geodata by

private users

• The work of the Initiative is divided among several Working groups.

• WG GIS: responsible for projects concerning the construction of a Geodata Infrastructure.
