That's because mapnik maps are raster images that are just blatted to the screen. All the work needed to generate those images from the vector data is done by the server you connect to, which then just serves up pieces of imagery for you to display. Off-line, Xastir either has to have a huge cache of those raster tiles (it is possible to cache them, but not automatable, if I understand correctly), or it has to render vector data locally. Rendering vector data is slow and Xastir's rendering engine is NOT up to Mapnik's standard. > The end > result is gross.

No, renaming the dbf files to dbfawk is very much the wrong thing to do. What you need to do is make sure that your Xastir is built with pcre and dbfawk. Please post the last block of lines that "configure" prints, where it has all the features listed and whether they're enabled or not. dbfawk is an internal feature of Xastir, pcre is an external library you need to have on your system with its development headers when you configure Xastir. Shapefiles look like crap without dbfawk, except for a small handful of extremely outdated shapefiles that have hard-coded support. You can't get any maps that look like the mapnik maps unless you generate them with mapnik or pull them off the web live. Xastir's map rendering engine just isn't sophisticated enough to do much better than it does with dbfawk. But without dbfawk you are wasting your time with shapefiles. > I was also wondering..

Yes, Xastir will keep your station on screen if you use TrackMe, and highlight it with a bunch of colored rings. > On Sun, Jun 10, 2012 at 10:45 PM, Curt, WE7U <[email protected]> wrote: > > > On Sun, 10 Jun 2012, Kurt Savegnago wrote: > > > > I simply moved the old TAMU tiger directory to /usr/local/share/xastir so > >> if I want to use them again, I just swap out the OSM shapefiles to > >> /usr/local/share/xastir and put the tiger maps back in to > >> /usr/local/share/xastir/maps.
