A graticule shows latitude and longitude lines on a map. When a graticule is built, vertices are added at one degree intervals, by default. This is to allow the graticule lines to bend to better fit the curvature of the graticule. In some cases, such as large scale maps or precise data, the amount of densification may need to be increased to better fit the graticule to the data.
Graticules use a default value of one, when densifying the lines. This means a vertex is placed every one degree along the graticule line. This is sufficient for many maps; however, some maps with more precise data or very large map scale may require more densified graticule lines.
Starting at ArcGIS 9.2 Service Pack 4, a registry key can be set that allows the amount of densification to the graticule lines to be adjusted manually.
The key was new at ArcGIS 9.2 Service Pack 4. It has no effect on previous versions of ArcGIS Desktop.
To use the AdvancedArcMapSettings program or to edit the registry, administrator or power user privileges must be granted.

This article contains instructions to make specific changes to essential parts of your operating system. If these specific changes are not done correctly, it may cause serious problems to your computer operating system and files. First, ESRI recommends that you make a complete backup of your system, including the registry, before implementing any of the specific changes. It is highly recommended that you consult with your IT/MIS department, or other qualified computer systems professional before proceeding. ESRI cannot guarantee that you can solve problems that result from incorrect use of the Registry Editor utility. Use the Registry Editor utility at your own risk. Note: your operating system and any subsequent service packs may effect these instructions. These instructions are subject to change without notice.
If the Settings folder doesn't exist, it can be created by selecting the Edit menu > New > Key.
