3 DATR, FÖMI s solution for cadastral map management Basis: MSZ Standard (Digital Base Map Conceptual Model) in Cadastral Domain since 1996 and DAT Instructions since 1997 Visions: Map all the principles of Unified Land Registry Compatible with the Standardized Domain Authentic updating of legal and geometry part of Unified Land Registry Independency from any commercial GIS solutions Full integration with existing TAKAROS system (Land registry) Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 3/10

4 DATR, Characteristics Providing authenticity No map editor capacity Map updating only via database transactions (in standardized environment) Uniform database structure Enforcing database integrity Real-time queries via Internet Integrated search with Land registry part Real-time map generating Minimizing network weighting Modular self-calibrating architecture All functions are in modules No client-side configuration is needed to insert any new module Easy customizable Uniform calling interface and protocol Opened module API Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 4/10

5 DATR, Core Data Model This Core Data Model is compatible with ISO Land Administration Domain Model standard proposal (by our Dutch Colleagues) Errors Surface Cadastral map Status Subparcel Geometry Margin Line Apartment Land Parcel Building Owner Real Property 0,1 Restriction Rights Boundary Boundary line Point Natural Person Address Non-natural Person Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 5/10

6 Real property transactions in DATR (according to the Hungarian regulation) Time Land Office t 0 registration Changing area Map Map Data service Surveyor Cadastral map t 1 Map Client Map registration Uploading t 2 Notice Adding a clause Checking t 3 registration Land registry t 4 Decision Updating Legal Transaction Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 6/10

7 DATR Architecture Kernel Database Base classes Graphic eng. Base modules APPLICATIONS Database FileI/O Open APIs Outer modules Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 7/10

8 DATR, International Version Because of the flexibility of the system, FÖMI decided to share this software with the land administration community All modules have a lingual description in XML format. Therefore lingual customization is very easy By the use of open APIs the system can be modified to any legal and technical environment New interface to Open source MySQL RDBMS (beside the existing ORACLE interface) If client needs any SQL based interface can be developed Full technical and professional (not only IT, but LA) support and guidance Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 8/10

9 General on workflow on CM in DATR OFFICE Map database integrated with land registry Data supply (in a given formats) from map database Office receives new CM data, checking based on data supply, making clause Result: CM updated and claused authentically Receives data, makes the job, convert new CM data into a given format, application for map updating Given format: Arbitrary format, which is able to hold geometric, topologic and attribute information of a cadastral map SURVEYOR TIME

10 Conclusions DATR is an object-oriented approach and a flexible solution for authentic unified land registry management DATR International version will be published as a freeware software, only registration needed FÖMI s capacity both in IT and land administration professionals guarantees the long-term maintenance and support of the system Linguistic Customization of the system is very easy via linguistic descriptions Open APIs help anyone to customize the system into his legal and technical environment FÖMI is ready to undertake the task of customization and/or professional guidance for the users of DATR, as well Institute of Geodesy, Cartography & Remote Sensing,, Budapest, HUNGARY 10 10/10
