24 User-specifications specifications TOP10-21st century (1) in the Netherlands Link older and newer versions Open standards (OpenGIS) Meta data Real world objects Needed Needed Needed Needed Covering the whole country, no gaps Needed

25 User-specifications specifications TOP10-21st century (2) Time aspect of objects Multi-scale representation Needed Wished Linking with other (thematic) databaseswished Payable use Usability Delivery via Internet Nice-to-have Wished Nice-to-have

26 Linking older and newer versions of Top10vector 1) Protection of users investments in the current version. 2) Possibilities for data exchange with customers that do not buy updates 3) (New) customers must be able to start using every available version Re-use of objects that did not change must be possible

27 Meta-information required Making available data on the data on object level 1. Description of the classification structure of the objects; 2. Information on the manner and time of data gathering and on the latest check, per object; 3. Information on the quality of the individual object data (precision, reliability, up-to-dateness).

35 Designing the data-model and its structure the following user requirements are taken into account: Object-oriented data-model with unique ID More attribute Integration TOP10vector and TOP10roads Change-only data instead of a complete update Historical information will be available Meta-data on object level Distinction Landscape Model and Cartographic Model Seamless database, complete coverage of the Netherlands Scale less database Automatic generalisation Linkage with the present TOP10vector Linkage with other databases Standardised way of exchange of information
