future directions for mapserver

[Marc Jacquin]

Kleith,

Seriuosly, how can you edit vector data as GIF images ?? With SVG or CGM you may, I agree with plug-ins. The prototype shows that editing is possible but only by transfering vector data to the client. And when compressed  (in this case of 250 fields) it represents only 50 Kb.

I suggest you to use OpenGIS WMS as I am using in my client:

http://opengis.jrc.it

Between my servers and my client I don't actually transfer vector-
data, but using MapServer, I convert it to GIF images. In that
way the transfer gets much faster. The OpenGIS WMS protocol
as it is implemented in most prototypes until now does it
like that, but it also forsees to actually transferring vector
data. To get more information about WMS look here:
