A vision for a national approach to land parcels in the United States
Cowen, David J.
Powerpoint presentation.
In 1980 the National Research Council report Need for a Multipurpose Cadastree found that obstacles to change were mainly institutional and organisational. What has happened in the last 27 years? 1980 Analogue Registered Overlays 1990 Multipurpose Land Information System 2007 Rigorous data model in place Dept of Homeland Security has stated that parcel level data is very desirable to mitigate against disasters for example hurricanes and forest fires and even fraud. In USA there are 3219 counties. Each has parcel level data. The issue is how you get local authorities to share this data when each has very different rules, regulations and pricing concerning dissemination of data. Lack of interoperability is widespread but North/South Carolina have W1 Land Admin Cowen managed to achieve joined up parcel data across their state line. There is a need for financial support from Federal level funds to join up all these initiatives. It was suggested a cost of approximately $300m might achieve this. Several private companies are now collecting parcel data in the USA. Whilst Google and Microsoft have access to parcel level data in Australia, this has not yet happened in the USA. The presenter suggested that the Federal Government in USA should keep an inventory of its property, which at present it does not do.
