UK revised the rules following the incident at London a few months ago, so all airports and approaches now have a clearly defined no-fly zone. However...
It all depends on the quality of the original media. We haven't thown away our old discs once they were backed up to more modern media. We still occas...
Depends what is being asked for - just images? orthophoto? proper survey info? If you are just being asked for images there are plenty out there who ...
TIFF's tend to be around 10 times the size of a JPEG. If you can save as a JPEG it should be suitable for most purposes (such as acting as a backdrop ...
Mapping water is the easy bit - it tends to be level! Getting an ortho image of large expanses is the problem - lots of photoshopping. Lee Green outli...
It's a shame that the Ordnance Survey Ireland don't talk to mapping organisations who understand these things, such as the Ordnance Survey Great Brita...
Robust method is fine, but bear in mind that if the question is asked about what a prism constant is, the questioner is probably now totally lost. Sim...

Yes, the problem will never go away. I've lost track of the number of tenders submitted where we can spend a couple of days completing all the "Techni...
Generally a lot more weather resistant than the surveyors! I've never had one fail in the rain (although I've never had one underwater to find out whe...
I've been using robotics since the GDM4400 was first produced and never found any accuracy problems. What you will get is a somewhat reduced range if ...
I know the feeling! In the end I move the base station and that solves the problem. After the early days we made our own brackets to point both base a...

It happens on quite a few packages. Some also have options for setting drawing scale view and screen scale view separately. We once had a client where...
Very neat, but you would need to go round and collect them at the end of the job - OK for small sites, but a lot of extra walking on large ones - see ...
Simplest is a can of white paint. Make a cross - depending on your camera 1" wide each arm 6" long may well do. (Check out by painting one on a wall a...
RTK and PPK are widely available on drones. Accuracy depends partly on the fact that a typicla flight may have 500 or more positions and when these st...
Perhaps you need to look around when our insurance is next due. In 40 years I've never been asked for that as a requirement. Even for ISO9000 we only ...
I haven't used these, but we did once try a plastic coated one - the problem was that some impact damage occurred to the plastic, water got in, the le...
I started with Wild GST20's nearly 40 years ago. They are still as good as new - quality products always shine through. Every 10 years or so they get ...
