Hi Joseph,
I'm a bit slow of the mark but here goes...
Another option is to merge your grids into one mosaic, and then being able
to image all of your grids together. I have no idea how big your surveys
are, if they are big this is quite taxing on your system resources, however
if they are of moderate size and reasonably close it can be quite effective.
The biggest benefit is using the image tool to image and stretch all your
grids at once.
To implement this I use a scripting language (in my case perl) to write a
geosoft script and then execute the script in oes to do the merging.
#
#Perl script to write .gs to merge listed grids.
#
@lines = qw( 282500.grd
282700.grd
282900.grd
);
# Create oasis script to merge grids into one
open(GS,">gridmerge.gs")|| die "Couldn't open gridmerge.gs";
system "del in.grd";
system "del merge.grd";
print GS<<THE_END;
SETINI GRIDBOOL.GRD1=".\\$lines[0](GRD)"
SETINI GRIDBOOL.GRD2=".\\$lines[1](GRD)"
SETINI GRIDBOOL.OUT=".\\merge.grd"
SETINI GRIDBOOL.BOOL="1"
SETINI GRIDBOOL.SIZ="3"
SETINI GRIDBOOL.OLAP="2"
GX gridbool.gx
SETINI WINEXEC.COMMAND="copy merge.grd in.grd /Y"
SETINI WINEXEC.ARGS=""
SETINI WINEXEC.TYPE="D"
SETINI WINEXEC.EXIT="D"
GX winexec.gx
THE_END
for ( $i=2; $i<@lines; $i++ ){
print GS<<THE_END;
SETINI GRIDBOOL.GRD1=".\\in.grd(GRD)"
SETINI GRIDBOOL.GRD2=".\\$lines[$i].grd(GRD)"
SETINI GRIDBOOL.OUT=".\\merge.grd"
SETINI GRIDBOOL.BOOL="1"
SETINI GRIDBOOL.SIZ="3"
SETINI GRIDBOOL.OLAP="2"
GX gridbool.gx
SETINI WINEXEC.COMMAND="copy merge.grd in.grd /Y"
SETINI WINEXEC.ARGS=""
SETINI WINEXEC.TYPE="D"
SETINI WINEXEC.EXIT="D"
GX winexec.gx
THE_END
}
close(GS);
system "oes gridmerge.gs /NEWGWS=temp.gws";
Cheers,
Andrew.
