Official real estate register information system — Basic data stock/Inventory data extract

In the Official Property Register Information System (ALKIS®), all data of the property register is merged and maintained integrated. This includes data from the former property map and the former real estate book in ALKIS. The basis for ALKIS® is a technical concept developed by the Association of Surveying Administrations of the Länder of the Federal Republic of Germany (AdV) for the management of all basic data of the official surveying system. All federal states are committed to maintaining an ALKIS basic data base according to this concept. In addition, according to the data model, additional country-specific data are available.在官方不动产登记信息系统（ALKIS®）中，所有不动产登记数据均实现整合集成与统一维护。该系统涵盖了ALKIS®中原地籍图与原不动产登记簿的相关数据。ALKIS®的技术基础源自德意志联邦共和国各州测绘行政主管部门协会（AdV）为官方测绘系统的全部基础数据管理所研发的技术概念。目前，德国所有联邦州均承诺按照该技术概念维护ALKIS®基础数据库。此外，依据该数据模型，还可集成额外的国别专属数据。
