I would really like to see some evidence of that, it seems incredulous to me that C-map would take raster data, devised from vector data and re-vector it!the post i was referring to was criticizing C-map
C-map starts with the raster charts - not with the survey data.
I've always used C-map cartridges in my plotter and found them excellent.
I've just done a google and found this Jeppesen C-MAP Professional
Which certainly says about its C-MAP Professional+
Dynamic worldwide vector chart database
- DNV type approved
- SENC format, CM-93/3
- Delivered on one DVD
C-MAP Professional+ is an innovative and dynamic worldwide vector chart database mostly derived from paper charts.
The coverage is continuously being expanded and new kinds of supplementary data are frequently added the product.
I suspect it just refers to that NAVTEAM product, not products produced by C-MAP
"NAVTEAM is your knowledge centre and system integrator strategically located in Svendborg, the maritime capital of Denmark. Since 2001 we have grown steadily" Nothing to do with C-MAP.
To add more to the confusion it looks like C-map do both raster and vector Chart Features | C-MAP
