Abstract
NCMA S.A. is the National Cadastre Company created in 1994 by the state to supervise the collection of topographic and legal information related to land parcel ownership, to serve as the legal custodian of this information for the general public, and to manipulate the Cadastre data, thus becoming the National Cadastre. The first IT System was established in 2002 in order to support the working Cadastre at remote locations. Between 2007 and 2009, NCMA managed to successfully implement CSFIII IT projects regarding the development of powerful IT infrastructure for web-services including modern data center and disaster recovery center, powerful computational, infrastructure, large storage system and sophisticated network and security infrastructure. In 2010 NCMA developed custom spatial APIs to support almost every spatial application of the cadastral projects, including the provision of services to third party. These services served over 300 million orthophotographs during the first year of operation. In 2011 NCMA delivered in-house web applications for the suspension of Rights (new surveys) and the on-line submission of application for correction of erroneous data. Furthermore the company created in-house web applications for the suspension of forest map and on-line submission of objections for the first time in Greece. NCMA continuously delivers web services to support citizens, professionals or contractors in every aspect regarding their relation with Cadastre with a goal to have a fully digital working Cadastre by 2018. All new Cadastre collection projects are already being fully supported by web services in order to have a unified and homogenized information database which has led to a great reduction in objection rates to an average of three per cent from an average of more than twenty five per cent.
