Grid Selection

- In the Map Projection field select the France grid number you want to use, this

should be the grid number the map uses for the +'s placed on the map as these are the points which

will be used for the calibration.

Use the + marks printed on the map for calibration. The numbers for the +'s are shown on the edge of

the map. You must add 000 to the IGN coordinates shown on the map edge to get the full Easting or

Northing.

New Maps (Lambert 93)

The new maps are much easier to calibrate as they have a full grid in UTM "WGS 84" printed on

them.

Select the Map datum as WGS 84

Select the Map Projection as UTM.

(Actually it may be more accurate to select the Map Projection as Lambert Conformal Conic and set

the parameters as Latitude 1 = 44deg, Latitude 2 = 49deg and the Central Meridian as 3deg.).

However it doesn't seem to make much difference to the calibration.

Calibrate the points using the UTM Grid on the map. You must add 000 to the UTM coordinates

shown on the map edge to get the full Easting or Northing.

The France Grid is also shown on the maps as +'s so it is also possible to calibrate using the same

method as the Lambert I, II, III, IV maps..

Changing the Name and Location of Map Images

The location and name of the image (link) for the map is stored within the map file (these files have

a .map file extension). If you move the map images then this link is no longer correct and needs to be

changed.

This feature allows you to :

1. Change the link for the map image within the currently loaded map to a new location or to a

new location and name if required.

Change the links for the map images for all the map files in a specified folder to a new

location. This option only changes the location (path) for the images not the image name.

Change the

Drive

specified in the links for the map images for all the map files in a specified

folder to a new location. This option only changes the

Drive identifier

in the location (path)

for the images not the full image path or the image name.
