Now a question: is anyone aware of a good tool for tweaking shapefiles,
as in
removing garbage points? I downloaded a GPS track, and there was a
single extra point at the beginning that was garbage --- several degrees
jump from
the first and second point, and after that it was fine. Xastir is drawing
a huge line from the starting point to the second point, and has a
rendering problem at zoom levels below 8 when it tries to draw that line
(fills the screen
with horizontal bars). Unfortunately, I cannot find any tool that will
let
me delete that first point from the shapefile. I've tried qgis, but even
though it'll let me edit the layer and will flash the point when I click
the "delete vertex" tool on it, it doesn't actually do the deletion.
Grrr.
Any helpful hints would be welcome.
Can't help you on the editor, except perhaps GRASS.
Quantum GIS (QGIS)?
Er... look up 6 lines or so. That's actually the only tool I tried, and it
simply didn't do the trick. It'd let me click the "delete vertex" tool on the
unwanted vertex till the cows came home, and when it saved changes the stupid
thing was still there.
To use GRASS would require importing the shapefile to a GRASS format, using
v.digit to tweak it, then exporting it as a shapefile again --- and GRASS
would then monkey with the attributes.
Sorry! I did miss that. Please feed that back into the bug reports for
QGIS. I'll see if I can duplicate and feed it back as well.
