[GRASS-user] v.in.ascii: 6 points imported, 4 displayed

GRASS GRASS user

   Using v.in.ascii 6 points were imported but only 4 display on the map
window. All 6 appear in the attribute table; when I right click on the each
of the two invisible ones and select 'highlight selected feature and zoon'
the symbol displays in a light yellow rather than the black of the 4 visible
points.

   Input data are:

1|-123.184|45.212|157|0.3E
2|-123.210|45.215|132|1.0WNW
3|-123.187|45.232|163|1.5N
4|-123.134|45.195|159|Airport
5|-123.204|45.211|137|0.6W
6|-123.270|45.240|458|4.3WNW

and the command line is:

v.in.ascii in=wx_stat.txt out=wx_stats x=2 y=3 z=4 cat=1 columns='cat int, \
x double precision, y double precision, z int, lable varchar(20)' --overwrite

   I am not seeing a problem with the data or command, nor do I see a
potential explanation on the manual page.

   A clue stick is needed.

6|-123.270|45.240|458|4.3WNW

quick test here; just zoom out and you will see 6 points.

Helmut,

   I tried that before posting the message, and saw nothing with several
'zooms.' Now, of course, they appear.

   I also tried 'zoom to selected maps' and nothing happened.

   Wonder what changed.

Thanks,

Rich

'zoom to selected maps' with this 6 points means :

Point 4 and 6 are exactly on the left and right border of the map canvas,
therefore you can see the points hardly. if you change the point symbol and
enlarge the symbol, you can see the points.

Helmut,

   That explains it. And, before your response I had the symbols colored
light grey so they were difficult to see against the white background at the
very edge of the view field. Now the symbols are colored red and easily
seen.

  Sigh, I was not sufficiently caffinated.

Thanks again,

Rich
