This is a 'comment field' and can be any information. The comment is stored in the 'mapfile.dat' file that is associated with the custom picture.

Four courners method

Using this method it is possible to geocode non-rectacular pictures.

Corners (upper lef, upper right, lower left, lower right)

Coordinate of the associated corner in Latitude Longitude. Latitude and Longitude are in the format 'degrees.decimal-degrees' with map date 'WGS84'

Modify

Here the coordinates from each corner of a image is displayed. Using 'modify' the coordinates can be changed per Latitude and Longitude.

After 'modify' a window is displayed where the precise coordinates can be entered.

Cursor

When the coordinates are unknown the active cursor coordinates can be copied in to the Latitude Longitude fields.

Centre and size

Using this method it is possible to geocode non-rectacular pictures.

Centre position

Coordinate of the centre position in Latitude Longitude. Latitude and Longitude are in the format 'degrees.decimal-degrees' with map date 'WGS84'

Modify

Here the coordinates of the centre of a image is displayed. Using 'modify' the coordinates can be changed per Latitude and Longitude.

After 'modify' a window is displayed where the precise coordinates can be entered.

Cursor
When the coordinates are unknown the active cursor coordinates can be copied in to the Latitude Longitude fields.
Vertical size (Km)
This is the length in Kilometers covered by the height of the picture.
