data frames, neatlines, graticules

In ArcMap sometimes you want to add lat/lon ticks around your map, add a scale bar, etc.

This stuff is all filed under Page Layout and Map Composition. You see most of this stuff under the Layout View, not the Data View. (Buttons in lower left corner of map window toggle these.)

data frame: most fundamental element in a map document and in ArcMap user interface.

neatline: border line commonly drawn around the extent of a map to enclose the map, keeping all o the information pertaining to that map in one "neat" box

graticule: the grid of intersecting lines, esp. of latitude and longitude on which a map is drawn. vs. gridicule.

Accessing the Grids and Graticules wizard:

1. Click the View menu and click Data Frame Properties.
2. Click the Grids tab.
3. Click the New Grid button.
