OSNI Large Scale Dataset The Large-Scale Vector product is produced from the large-scale database. The Large-Scale Vector database contains 17,335 individual tiles; each tile represents one map sheet originally surveyed at either 1:1250 scale or 1:2500 scale. Urban areas, covering 6% of Northern Ireland, are mapped at 1:1250 scale and each map tile at this scale covers a ground area of 600x400 metres. The remaining 94% of Northern Ireland is rural, and is mapped at 1:2500 scale, each tile covering a ground area of 1200x800 metres. RURAL (94%) URBAN (6%)

OSNI Road Network Dataset Road Network is a vector dataset showing all Motorways, A-, B- and C-Class roads in Northern Ireland. All roads are named in full and show Road Classification and Road Number. OSNI Road Network has been created as a continuous network allowing users to plan the shortest route between points. By matching and verifying Road Network against Pointer and Road Service data, OSNI have created the most accurate and complete road dataset in Northern Ireland.

OSNI Road Network Dataset Update 1Spatial are developing a process to allow automatic geometry updates on a quarterly basis from field survey database DIS are then going to add name, road class and road number to the attribution There is no easy way of adding drive restriction attribution Data quality issues need fixed in Fermanagh prior to mapping being produced for council consultation (to approve road names)

OSNI ORTHOPHOTOGRAPHY Refresh tiles have all been flown and should be processed by early June New coverage diagram now available to customers allowing more accurate identification of date flown New refresh will then commence New format – jpeg to replace ecw 12.5cm resolution orthos will be produced for urban areas Flying priority will be determined by LPS requirements, PI, NIMA customers Plan to purchase a new digital camera in (part of DARD programme) – there will be a crossover period when both cameras will be in operation

OSNI ORTHOPHOTOGRAPHY

A major issue for all OSNI Orthophotography customers is the date of flying. This is a complex issue, as the diagram demonstrates – each orthophotography tile is made up of a number of images, with the potential for each tile to have a number of flying dates. LPS have now released the ‘seamlines’ data, which shows the make-up of each tile (from the ‘raw’ imagery), along with the ‘photocentres’ data, which provides the flying date for each ‘raw’ image. This data can be found in Data\ Coverage_ Diagrams\ESRI Shapefiles\ Orthophotography Tile Layout in osni_digital_data on osfilesvr. This data has been released on the understanding that it should be used as a guide only – if any customer needs to verify ground detail, and the date of flying, they need to use the original aerial photography.

Other Products/Issues New 1:1,000,000 raster being produced this year – to be set as initial image on website.
