Once the recorded imagery is received in the office the data is 
copied to the company network file storage and geo-referenced by 
an XPro application. The XPro Ingest package is fully connected 
fo the Production Tracker allowing the actual footprints of the 
243 
imagery to now be viewable in the Production Tracker 
immediatly- see Figure 6.

At this point all the imagery goes through a quality control process 
where any issues are recorded in the XPro QC image viewer 
which has been extended to communicate directly with the 
Production Tracker catalogue. Issues are traced with a feature 
drawing utility and persisted directly in the catalogue. A user with 
management rights then calls the re-flights and re-flight lists are 
sent automatically back to the flight crew. 
The ability to view the actually flown flight lines before receiving 
the full data set together with the re-flight call functionality has 
helped optimize the flight order and therefore made the daily 
planning while the acquisition team is on location more efficient. 
CONCLUSIONS 
The enterprise mapping system as introduced in this paper has 
been a large step forward for the overall company productivity at 
NWG. The ability for stakeholders to view the progress of 
individual projects while being flown has helped identify potential 
problems earlier in the life cycle of a project and therefore reduced 
cost. The necessity for copying and moving data of the storage 
devices has also been greatly reduced as all the data is now stored 
in a central repository. 
While only the work flow steps through initial QC have been fully 
implemented for production, the benefits have become obvious. 
The development of the remaining work flow with a tight 
coupling with XPro applications is underway. Initial plans to 
tightly integrate the Production Tracker with the online delivery 
system for other value added products like a point cloud that
