Tracing Application with MapServer

[Zhonghai Wang]

Hi guys,

I am in a project about tracing with MapServer. I am glad that it's running
very well. But there is still one situation that I can not handle, I know
that this may not be a problem about MapServer itself, but the GIS and GPS
GURUs here may have some ideas .

Sometimes the coordinate obtained with GPS is not accurate enough, it may be
totally out of the street, even about 10 meters, if this point is displayed
on a map with a large map scale, it should be a mistake. Does anyone has any
idea to interpolate such a point, so that it gets back to its "right"
position.

thanks for any advice.

Best Regards

Zhonghai
