Christian, Your email to gembud bounced because your address on the list is gmail.com, and not the uqam.ca from where you sent this message. Answers to your questions: 1) No, the filter is dynamic, using available stations, so which stations are plotted depends on whether there was missing data for a previous station (in general, the plotting is the order of the stations in the surface file, which is the order of the stations in the station table), but when stations are not reporting, the lower priority station may appear. However, you can add a station priority in the station table, and use the SFPARM=SPRI field (with a qualifier such as ">val" for instance). 2) To use an imagemap, if you use a CED projection, the lat/lon of the station is easy to relate to x/y pixel space in a GIF/PNG, if you know the lat/lon bounding box. Otherwise, the projection location will be more complicated.
