Location formats and grids

The application can display and search locations in almost any coordinate system.

For all of them, the associated grid (geodetic or projected) can be displayed on the map, along with grid square notations for UTM, MGRS, OSGB, Irish Grid, TPC Grid and DFCI grid systems.

By default, the coordinates of the screen center location are displayed in an information box located at the top left of the screen. If an secondary location format has been chosen in the application settings, both are displayed. The coordinates and grid of the secondary format are displayed in blue.

To display or hide the screen center coordinates information box:

• Tap on the main application menu ;
• Tap on “Options” ;
• Check the option “Screen center coordinates” to display the coordinates, or un-check it to hide them.

To display or hide the grid for one of the current location format:

• Tap on the main application menu ;
• Tap on “Options” ;
• Check the option “Display grid” to display the grid of the main location format, or un-check it to hide it;
• If you've chosen a secondary location format in the application settings, you can display its grid or hide it independently by using the option “Display alt. grid” . The secondary format grid is displayed in blue.

• Type the EPSG coordinate format ID in the text field ;
• If you don't know it, tap on www.spatialreference.org to visit this website that list almost all coordinate formats. You'll be able to make searches by name or country, and retrieve the list of corresponding coordinate format IDs;
• Tap on “Ok” to validate;
