About the Products

How is the photograph taken?
All of the photography on the Bluesky Mapshop is taken using state of the art digital survey cameras from aircraft.
What will I be able to see in my photo?
The detail in the photos is impressive. All of the photos are at a resolution of 25cm or greater (ie each pixel in the digital photo represents 25cm on the ground, this is often referred to the Ground Sampling Distance - GSD). The standard resolutions allow you to see street furniture and inspection covers.
How up-to-date is the photo/data?
All our photography and data is captured between 2015 & 2016.
I require more recent data for my area. When will it be updated?
The Mapshop will always offer the most recent data available, but if you require very up-to-date data or your area is unavailable, this may be in our flying plan, or might require a special survey. Please call our sales team on +353 (0)21 2409026 for more details.
How geographically accurate are the photographs?
The Mapshop offers some of the most accurate aerial photography available, as it has been fully orthorectified. Independent tests have shown the accuracy is better then 1m RMSE across the entire dataset. In many areas it is even much better than this, as much as 20cm RMSE in some areas. All digital files are supplied with associated georeferencing information to allow you to view the images in GIS etc.
What is an orthorectified image?
The term orthorectified refers to an aerial photography that has been geographically referenced, placing each pixel in it’s correct geographic location, using a DTM. The process removes all errors caused by the camera lens and the undulating terrain, and involves the use of GPS information collected on the ground as well as in the aircraft. All data in the UK is referenced to the Ordnance Survey National grid system.
What is a JPG/TIFF/ECW/ASCII/DXF Point? What format do I need?
These are all data formats. JPG, TIFF and ECW are all image formats and ASCII and DXF Point are height data formats. JPG and TIFF can be read by many common software packages (they are the same as images from a digital camera). Both JPG and ECW are compressed formats, whereas TIFF is uncompressed. We would always recommend JPG as the file volume is much smaller, and the loss of data during compression is negligible. ASCII and DXF Point will need a GIS application to view the data.
Can I select a specific area for digital files?
Yes you can select any area and any size you require. Just use the tools to the left of the map window.
I can see a join (marked colour change) in my photo preview.
The aerial photography offered on the Bluesky Mapshop is made up of many hundreds of thousands of individual aerial photographs. There may be a time difference of several years between two photos, and they may have been taken at different times of the year. Our expert team do their utmost to minimise the visible join between two dates, using state of the art image processing software, but sometimes only so much is possible without causing damage to one or both of the photographs. If the join is extreme, please let us know and we might be able to improve it.
What is height data?
Height data is a digital file that depicts the height of the terrain and/or features on the terrain (DTM and DSM). It is in it simplest form a grid of points at a set spacing (5m for example), each with the height of the terrain or feature attached. This type of data allows the user to get a feel for the ‘lie of the land’. Only Professional users should use height data, as it is information rather than an image or a picture.
What is a DTM?
DTM stands for Digital Terrain Model. This is a form of height data that depicts only the surface of the earth, ignoring features such as trees and buildings.
What is a DSM?
DSM stands for Digital Surface Model. This is a form of height data that depicts the surface of the earth and features on it, including tress and buildings.
How accurate is the height data?
The accuracy of height data offered on the Bluesky MapShop is better than 1.5m RMSE in the x, y and z.
