OSi Annual Report 2009 English Version - Ordnance Survey Ireland

MAPPING PRODUCTION DEPARTMENT
The role of the Mapping Production
Department is to collect the primary
geographic data that provides the basis
for the creation of the mapping
products for OSi customers in both
digital and paper format.
The Mapping Production Department is
responsible for ensuring that the
mapping which the customer receives is
both current and accurate. OSi has staff
with an extensive range of skills, from
traditional surveying and cartography
to postgraduates in GIS, IT and
photogrammetry. OSi field staff
members are equipped with the latest
GPS surveying equipment and field
computers, which are used to update
the mapping on the field.
The Mapping Production and Mapping
Technology Departments collaborate to
ensure that the most efficient and
effective methods are used to collect
new data and update the mapping. The
OSi flying team captures aerial
imagery, which is processed using
aerial triangulation. Skilled
photogrammetrists then plot real world
features to update the OSi mapping.
The plotted data is passed to staff
members who are skilled in the use of
modern map editing software for
completion. Staff members are
generally trained in more than one
technology and work on a number of
these.
2009 reported efficiency improvements
in the Revision Programme and, in
many instances; OSi exceeded the
expectations of customers. For
example, the Urban (1:1000) and
Suburban (1:2500) mapping of Ireland
is now being maintained within a oneyear
revision cycle; the Peri-urban
(1:2500) within a three-year cycle and
the Rural (1:5000) mapping is within a
five-year cycle. The updating and
improving of the 1:10,000 database
also continues in line with production
and customer needs.
Previous Annual Reports have
commented on the very major project
which OSi has undertaken on behalf of
the Property Registration Authority
(PRA) involving the implementation of
Digital Mapping technology as part of
an Integrated Title Registration
Information System (ITRIS). OSi
mapping data is central to the
successful completion of this project
and is being supplied to the PRA in a
digital format using the new ITM (Irish
Transverse Mercator) coordinate
reference system. This project
epitomises the significant advances that
OSi has made in applying the latest
technology innovations to practical
usages in assisting customers to realise
greater potential from OSi data. The
PRA project ultimately serves the
national interest and does so through
the application of a digital mappingbased
solutions approach designed and
fashioned by OSi.
For OSi, this contract involves the
supply of all mapping (scales 1:1000;
1:2500 and 1:5000) for all counties in
the State and the re-supply of revised
mapping data at agreed intervals, thus
ensuring the currency of the records
that will underpin the PRA system.
Since the inception of the project, all
deadlines have been met by OSi and
this project, because of its complex
technological nature and demands on
both, has resulted in the fostering of a
strong professional working
relationship between both
organisations.
