Surfer Tip: Refresh Your Maps
with New Versions of Files
There are times when you have your maps just the
way you want them, but there are newer versions of the data and grid files. How
do you get the new version of the data and grid files into your existing map?
Many of the Surfer map types have a yellow Open
Folder icon 
to the right of the source file name on the General tab of the Properties
dialog box. When you click on this icon, you can specify a new file name, or
click the Open button to reload the existing file.
Click on the yellow Open
Folder icon to reload an existing file
or specify a new file.
This procedure can be especially useful when you
are comparing different gridding methods to see which one best represents the
data. Overlay a contour map and a post map with the data point labels to compare
the contours to the actual data point values. Regrid the data with a different
method or search parameters, and substitute the new grid file for the old one.
When you reload your data or grid file, or
specify a new grid file, Surfer resets the map limits to the full extents of the
map. If you wish to preserve your map limits, use the refresh.bas
script from the Golden Software FTP site.
Surfer 8 Scripts
ftp://ftp.goldensoftware.ws/public/scripts/surfer8/
Download the script, open the Surfer Scripter
program with the Windows Start | Run | Golden Software Surfer 8 | Scripter
menu command, and choose the Scripter Script | Run command. As written,
the script uses the first map frame with the Object ID equal to "Map".
If you would like the script to instead prompt
for new data files, you will need to change several lines of code in the script.
OLD:
ovrly.DataFile = ovrly.DataFile 'This line occurs once.
ovrly.GridFile = ovrly.GridFile 'This line occurs three time.
NEW:
ovrly.DataFile = GetFilePath(ovrly.DataFile)
ovrly.GridFile = GetFilePath(ovrly.GridFile)
