Interoperability is the key for SDI’s
But in surveying…?
It is still far from that!

Lawsuit & Verdict after a tender
The 'Windows Mobile' operating system of the controller uses
standard two authentication protocols for accessing the RTK
signal. And that is Password Authentication Protocol (PAP)
and Challenge Handshake Authentication Protocol (CHAP).
The Dutch Kadaster supports only PAP. When the two
protocols are offered, the connection is denied. It is stated that
Windows Mobile 6.5 does not allow for switching between
both protocols. This is only possible if the software is
modified.

But still problems
• Connectivity tablet – survey instrument
• Trimble: Radio
• Leica: Long Range Bluetooth
• Is part of tablet!
• Tablets are other EU tender
• Leased from Capgemini
• Capgemini = ‘office oriented’. Hard struggle to get real ruggedized
tablets
• Different duration of tenders!

But still problems
• No open protocol for software – device
• Trimble SDK
• Leica GeoCOM, OWI
• Topcon provides interface with Non Disclosure Agreement
• NMEA has only coordinates (no covariances matrix).
• No standard for controlling instruments
• Vendor’s are ‘reserved’: who is to blame?

Conclusions
• Interoperability (=independency of vendors) is labour some
• No ‘OGC’-standards for surveying
• EU tenders make it hard
