The supplier behind a national land and property database has bowed
to pressure from data experts and will publish a "comprehensive"
report to demonstrate the accuracy of its information.
The National Land and Property Gazetteer (NLPG) will underpin the
National Land Information Service (NLIS) - an online search
facility for land and property information.
The u-turn comes less than a month after address data experts
criticised Intelligent Addressing - the supplier helping local
authorities to feed data into the system - for refusing to reveal
details of an internal survey which matched the NLPG against Land
Registry records.
Intelligent Addressing claimed that the NLPG achieved a 97% match
rate in the exercise. However, last month software suppliers and
local authority IT professionals claimed that 20% of the data in
the NLPG could be inaccurate. Both Intelligent Addressing and joint
NLIS project leader Local Government Information House denied this.
Michael Nicholson, chairman of Intelligent Addressing, said, "The
NLPG is subject to a rigorous process of quality control. As a
result of this process, a comprehensive report on the quality of
the NLPG, which will include comparisons with other datasets, is to
be published imminently."
