Mike Peterson here. In the use, we use the term “differential GPS”. You were clearly talking about that with your RTK base stations. Is the term not used here?
Owen Macdonald

Hi Mike. I certainly grew up with that term (or differential correction) but RTK and such like has become more the new norm - an excellent first question I think!...
mpeterson

A second question would be on Lidar. Does UK have a national Lidar mapping program? It’s done in the US by individual cities/counties - sometimes a consortium of cities/counties. But, not on a national level.

Isn’t RTK providing differential information too?

The new technology is becoming easier to use. Is there a danger that the surveyor’s traditional role will be changed?

for remoter overseas fieldwork, we always needed to bring out own base stations. in remote areas, do we still have the problem of long baselines to the nearest GNSS base station in a global network?

We are on Phase 3 and there is a plan to cover entire country

You mentioned the use of UAVs. Where is the major application? How much does the battery limitation limit its use?
Seamus O'Donnell
01:20:30
Thank you for your talk David. Do you think recent developments in photography will translate to photogrammetry? i.e. mirrorless cameras
neil

do you think the data captured by satellite based LIDAR offers opportunities to improve terrain models in e.g. Africa?
Seamus O'Donnell
01:23:19
No problem, thank you!
