Don't give up. What might work for you is to create two layers. the first has all the points; the second has only the latest point. Make the second layer the upper layer and give it a different symbol. Maybe that would do the job for you. Otherwise there is a way to 'make a line' out of points, but I have yet to figure that one out. Once you have that, presumably you could have a line with directional arrows on it. Cheers, Russ.
_____ From: UMN MapServer Users List [mailto:[EMAIL PROTECTED] On Behalf Of Ben Madin Sent: Thursday, 23 August 2007 1:20 PM To: [email protected] Subject: [UMN_MAPSERVER-USERS] Showing Movement Direction G'day all, I have been looking and reading, but I'm not sure I'm looking for the right thing. I have a number of points from satellite based tracking, giving me a list of longitude, latitude and a timestamp. These are fairly regular, and although I can display the points on the map window and see where animals have moved to, I can't tell which way they moved just by looking. We vets need to know what came first... So I thought I could convert adjacent points (temporally) into line segments, (earliest point first, latter point last), but I can't find anywhere in Mapserver that seem to explicitly explain how to do this (or whether it can be done). Can anyone either : direct me to the right place, or give me a set of keywords which might get me to the right place, or advise me to give up for now? cheers Ben -- Ben Madin REMOTE INFORMATION t : +61 8 9192 5455 f : +61 8 9192 5535 m : 0448 887 220 Broome WA 6725 [EMAIL PROTECTED] Out here, it pays to know...
