Get location

Click on the "Get my location" button to get your location and put it on the map with the red marker "M". The location details are also shown in the boxes at the top of the screen. If using a desktop/laptop device connected to the internet but without GPS, the location may be approximate, and sometimes wildly incorrect (in spite of the "Accuracy" reported).

Copy and Share

The "Copy" button copies the current MemCode to the clipboard, for pasting elsewhere. The "Share" button copies the current MemCode and invokes the share system to send this to another user.

MemCode

Fill in the six boxes with the six 3-letter words that form the MemCode - the program automatically adds the separators, which do not have to be entered. Click the "...use" button to the right, to convert this a HexCode and to latitude and longitude. Click the "Put on map" button to show the location on the map, marked with a blue "D". Use "Clear pins" to remove all "D" pins added.

HexCode

The box shows the 12-digit hexadecimal code for the currently active location. If you enter a code in the box and click the "...use" button to the right, this code will be converted to a MemCode and to latitude and longitude. If fewer that 12 digits are entered they are padded to the right, in order to place the location at the middle of the larger region specified. If more than 12 digits are entered they are truncated to 12.

Latitude and Longitude

The boxes show the calculated latitude and longitude (in degrees) for the currently active location, rounded to 5 figures. If you enter values here and click the "...use" button to the right, this code will be converted to a MemCode and HexCode. Latitude must be in the range -90o to 90o, and longitude in the range -180o to 360o (if a longitude greater than 180o is entered, then 360o is subtracted to bring it into the preferred range from -180o to 180o).

Map

The BING map may be moved and scaled in the usual way. Click anywhere on the map to show the MemCode for that location, which is marked on the map with a green "C". The location details are also shown in the boxes at the top of the screen.
