[mapserver-users] Postgis simplify function and mapserver
Hi list, I wish to change a query parameter in my postgis layer depending of the scale of the map I want, let's see: DATA the_geom FROM (SELECT finfres.gid as gid, ST_Transform(simplify(ambits.the_geom,5),23031) as the_geom ... So I would like to know if it's possible to pass the second parameter of simplify function depending of the map scale, without any value on the querystring (using %%).

Re: [mapserver-users] Asking for guidelines about a project
The database schema depends on what you want to do with the data (display current position? A track of historical positions?), and how much data you expect (how may objects will be tracked? how often will they report?). A simple schema would have one table (e.g. vehicles), with one row per tracked object Table: Vehicles ID:Name: Position: Status: UpdateTime: 1 My Carpoint(51,-115) active2011-06-16 10:23:54+02 2 Another Car point(52,-116) inactive 2010-05-15 11:13:12+02 With this schema, when a new position arrives for My Car, an update statement is issued to change the row's Position and UpdateTime (and possibly Status). The table is treated as a PostGIS point layer by mapserver. In my implementations, the position data was updated every 30 to 60 minutes (they were ships and construction vehicles), so there was no need to ask mapserver to regenerate a graphic every second; an updated map was shown whenever a user did a pan or zoom. You may be able to configure OpenLayers to do a CGI request to mapserver every few seconds, but I've never done that.

Thanks for ur answer and also Josh's answer. In fact, i should be able to display path of vehicles (usually more than 1 vehicle in display area) and also be able to save points passed by vehicles and time of passing (for some queries).

Re: [mapserver-users] Asking for guidelines about a project
Well, it's up to you how to model the objects (that's the great thing about relational databases). Typically, I've added a table of Historical Positions with basically the same structure as the vehicle table (but in that case the unique key is not the vehicle ID, but instead just a system assigned key like OID). As for the points passed by, I would not save that information in a table, instead consider it the result of a spatial query (say in a PostGIS view) at display time. A system like this usually takes a large of amount of time for requirements, investigation, design, and prototyping. And of course, construction, testing, documentation, and training. If you want something more packaged you can just download and install, you may want to do some searching on the web.
