costly


New technical requirementsNew technical requirements


Need for renewalNeed for renewal Integration of register and maps for a

better work flow ISO and OGC standards New business strategies in the

organisations Cadastre is a basic element of NSDI Internet, e-land administration


General strategiesGeneral strategies

Step by step big bang re-engineering within the existing

infrastructure conversion of existing mainframe

solutions into a client-server architecture


Step by step in the NetherlandsStep by step in the Netherlands General information

Roman and French system Notary Public plays important role Land registers and cadastre in the hand of

Kadaster 1,000,000 transactions per year cadastral registers and maps different systems,

parts more than 20 years old maintenance costs = 6 * modern systems


Step by step in the NetherlandsStep by step in the Netherlands

Renewal strategy was developed over 6 years = road map

find a balance between user demands for new functionality, availability and continuity and the demands on cost management and manageability





Renewal of the core system new system built up in parts in a new

environment while the old system is still running

10 years synchronising both systems periodical evaluation of the process

RecommendationsRecommendations

Step by step approach Complex and time consuming Parallel data maintenance for long time Customers have time to convert their

systems Employees‘ skills can be developed and

experiences may influence new components


RecommendationsRecommendations

Big bang approach Easier to implement Long development and test phase Short migration period Customers have to be involved Education program parallel to normal

work process New work flow needs new skills


ConclusionConclusion

Strategy has to fit in the situation in each individual country

All strategies have strengths and weaknesses

No cookbook, just good practice guidelines
