OSi’ has been quite busy in recent times, working to complete a series of coast-to-coast high definition aerial imagery. And their newest series of high-resolution 25cm imagery covering the entire country is now available, a product unmatched by any other supplier.

Completed in 2017, the 25cm-pixel Series One Imagery represents the most complete and accurate imagery dataset ever completed in Ireland and has been made possible only by significant investment in people, equipment and processes.

With all 26 counties fully covered at a pixel resolution of 25cm, they have over 1.1 TRILLION pixels of data on offer! Their full 26-county coverage allows them to supply data to all 31 local authority areas. This means that there are 20,326 tiles of 2km imagery (orthorectified) available nationally for every corner of Ireland.

Every field, building, river, street, every shed, road, fence and wall have been recorded. It is four times more accurate than all OSi’s previous datasets and was captured in half the normal time period. Indeed, further progress is expected for Series Two (2017-19), with the capture timeframe reduced to 2.5 years.

In addition, Ordnance Survey Ireland has just recently announced the availability of 15cm-pixel resolution imagery for the greater Dublin area. Captured during the summer of 2017, in near perfect flying conditions and processed to the highest quality, this represents OSI’s most accurate imagery to date. At 15cm per pixel, there are 44 pixels per square metre, so even the smallest object can be identified, measured, and its position recorded as required.
