My simple task is this. I can’t figure out how to get the graticule lines to show up on my map when I export it to jpeg, tiff, pdf, or anything else. The problem is by default the graticule lines show up in front of the countries or on top of them. I can’t send them to the back. The only way to send them back is to convert the grid to graphics. When I do this I can then send the graphic behind the countries, but when I export the map they don’t draw. Does anyone know how I can accomplish such a simple task? That is getting the graticule lines to show up behind the countries and then successfully draw? Any help is much appreciated!

Why not just use a graticule dataset instead? That way you can decide their visibility order (below countries but above ocean)?

If you cant find a source dataset, it's quite easy to generate them at set intervals...

Thanks for the reply! I just don't know what or where to get a graticule dataset or how to even start generating them at set intervals. Do you know where I can go to get started?

Well...off the top of my head I know that Tutorial Data that comes with the ArcGIS dvd has a grid you can use.

Alternatively, to make your own:
Create new line shapefile in suitable geographic coordinate system
Start Editing to create a new line, and swtich to Sketch tool (pencil)
Before adding a vertex, Right-click and pick "Absolute X,Y or use short-cut key of F6
Make sure the coordinates are rounded evenly
Then for the end point, right-click again and this time pick 'Direction'. Enter 90 to get a perfectly straight line
To duplicate the line, you can then goto Editor and "Copy Parrallel"
This is where you input the graticule spacing you want to achieve...

Repeat the process for latitudes and you're done.

BUT...the easier option is to use ET GeoWizards from http://www.ian-ko.com which has a quick vector grid creator tool.
It's part of the free version....

Best of luck....
Kind Regards,

Dustin
