LPS Northern Ireland aerial imagery
Features and benefits
Captured by Land and Property Services (formerly Ordnance Survey) Northern Ireland, the photographs are taken in optimal weather conditions to provide the best possible images.
Imagery is no older than March 2003 and will be updated for accuracy and currency.
Distortions caused by camera tilt and topographical variation are removed by an orthorectification process for a scale accurate image.
Orthophotography is an actual image, rather than a representation, and therefore can provide different types of information such as shape, size, patterns, shadows, colour and texture making them easier for some people to understand.
OSNI orthorectified photography can be used by itself or along with other data displayed in the Irish Grid Co-ordinate system.
Technical Information
- Each pixel represents a real world distance of 25cm
- The photographs are taken from an altitude of 5000 feet
- Fully geo-referenced digital orthophotography is available in JPEG format
centremapslive.com recommends Global Mapper as an extremely useful tool for handling purchased aerial imagery - particularly large or tiled data.
