hi again -- 'set gxout kml' does the trick:<br>
<br>
'set gxout kml'<br>
'set kml -ln kmltest'<br>
'set clevs 0'<br>
'd temp'<br>
<br>
the file kmltest.kml has the lon/lat/z (0) for each contour in
<coordinates><br>
lon0,lat0,0 lon1,lat1,0 ...<br>
lonN,latN,0 <br>
</coordinates> <br>
<br>
thanks /R Mike<br>

hi Jennifer -- I have a similar problem... I can generate and
display the shp file and the 'q shp' works as advertised, but what I
really need are the actually lat(Y)/lon(X) of the vertices not just
the bounds, e.g.,<br>
<br>
37: ArcM parts=1 vertices=553 XBounds=0:360
YBounds=41.4058:74.4189 ZBounds=0:0 MBounds=5700:5700 <br>
<br>
tells me there are 553 vertices and that the lon bound is 0-360 and
lat bound is 41.4-74.4. do I have to use some GIS s/w to get the
lat/lons? or is there a way to mod grads to output?<br>
<br>
thanks! best /R Mike<br>

GrADS can write out the shapefile for you. Use ‘set gxout shp’ and
‘set shp’ to control the output. Documentation is at <a

Exactly. I'd like get a *.shp file of the 0
contour's. It should be get the lat/lon of the
contour's position first, and then using Arcgis
software to generate the .shp file. <br>

Grads beginner. The data I used is the NECP 5
years average air temperature, I'd like get the
zero degree temperature line. After "set clevs 0",
I got the contours graphic (see attachment). But I
still cannot get the output file as your steps.
Could you please have a look at the attachments
and help? <br>
