Advantages of the data
Unexpected by-products
Other types of data being captured
Slide 3
Source Data
Ordnance Survey MasterMap Topography
Some form of base
data is essential and
the only product that
will provide the
accuracy that we are
looking for is
Topography
Slide 4
Source Data
Paper Ground Maintenance plans
You may be lucky
enough to have
hand drawn up to date
Ground Maintenance
plans, most don’t!
Slide 5
Source Data
Ordnance Survey Aerial Photography
Fortunately advances
in the digital photography
available, enables the
majority of Ground
Maintenance to be
captured without
paper plans
Slide 6
Source Data
Transfer Plans
You may also have
transfer plans or
Deeds that can be
used to identify the
limits of capture:
Slide 7
Source Data
Land Registry Boundaries
If not Land Registry
can provide
boundaries:
Slide 8
Source Data
In summary you need some base mapping, aerial photography and the extents of capture
Slide 9

Data capture
Identify anomalies
Manual quality assurance
Automated quality assurance
Anomaly clarification
Implement amendments
Export the data The elements in blue can be undertaken by anyone (including ODC) but the Neighbourhood officers should provide the Anomaly Clarification

Products
GIS data
Bill of quantities
Paper Plans
PDFs Can include large areas
Zoom in and out like a GIS
Separate Overlays for data
Attribution can be exported
Saves on printing costs (officers can take the whole set on-site and suppliers can print the elements they require)
Slide 13
Advantages of the Data
Portable / Easy to share
Improved information for the organisation
Accurate calculation of tenant costs
Save money Tender – better information better price
Renegotiate with existing contractor or Council
10% -15% reduction
Slide 14
By-products (Value Add)
Audit of existing property database
The property points and extents of
ownership are compared to identify: Property points that are not enclosed by a
boundary of ownership
Boundaries of ownership that do not enclosed property points.
The latter may indicate lost properties or land suitable for development.
Slide 15
Slide 16
By-products (Value Add)
Audit of existing property database
Confirm accuracy of Land Registry
information.
Identify lost properties or development
land.
Other Applications
