The dangers of GPS/GNSS
Börje Forssell
The problem is that nothing works 100 %. GPS is very close, but for some users under some circumstances, "very close" is not good enough. A question which is often asked is whether upcoming systems (Galileo, INRSS, etc.) will solve the problem. The answer is that they will reduce the problem but not solve it completely. [more]

Challenges before National Mapping Organisations
Vanessa Lawrence CB
"Whilst the technological developments have led to an explosion in the availability of data, they have made the information management task more complexed"

P Nag
"The issue is whether NMOs can cope up with the everincreasing expectations of the Government and the people at large?"

Lam Joon Khoi
"We must persevere to create a mindset of sharing and responsible usage of geographic information"

Quality evaluation of NRTK correction transmission
Lei Yang, Chris Hill, Xiaolin Meng and Jose Aponte
NRTK technology can remove spatially correlated errors and effectively mitigate distance-dependent errors in the GNSS measurements, and achieve a centimetre-level positioning solution. In such a high accuracy real time system, reliable and high-speed server-rover communication (i.e. correction message transmission) plays an important role in the final performance [more]

Geomatics in Pakistan
A W Mir
GIS culture is spreading. Everyone talks about it and wants to acquire it but majority are unaware that for quality GIS basic requirement is quality geomatics data [more]
