Use this area to find Google Earth overlays, complete gridded sectionals, and other information.

Use this section if you have Lon/Lat coordinates and need to find the associated grid.

We'll find the grid, then provide the grid corners, below.

Select a sectional and a grid identifier.

The grid's average magnetic variation is calculated from the current NOAA model and adjusted for yearly drift.

It may not agree with the isogonic lines printed on aeronautical charts.

This section shows a movable Google Map of the selected grid. You may also view a larger version of the map, or download an overlay to use with Google Earth.

This overlay is compatible with the Sectional and Terminal Chart overlays.
