the map. (Negative for angle measured
anticlockwise??).
•
X Coordinate: Easting of upper left corner of the map

(pixel 1,1)
Note that if the file was georeferenced earlier, all these
parameters may have been saved in a *.tfw, *.jgw or *.bpw
file. If that is the case, click on the
Import World Files
button, select the corresponding file and click
Open. This
causes all the fields on the World File Editor window to be
filled in from this file.
If there is not such a file, you have to work on finding
georeferencing information for the map, as explained in
Determining Georeferencing Information for an Image File
on page 3.
6. After entering all the parameters in the World Map Editor
window, click
OK to close it.
7. Select
Image Database>Add Image to Database. This opens
the Add Images to Database window in which the program
indicates that the original map is going to be split into
several smaller map sections, each in BMP file format.
The program indicates the number of files that will be
created in the horizontal (columns) and vertical (row)
directions
8. Click on the
Process button and wait until the program has
finished processing the original map. In the left column is
an example of a map split into three smaller map sections
arranged vertically (i.e. column=1; rows=3).
9. Click
OK to close the window.
10.Click
File>Save as Image Database and name the project file
(e.g. “Map1”). This will be a text file gathering the
georeferencing data of the map project as well as the
paths and names of the different bmp files created
through the above process step.
11.Click
Save to save the different files of the map project to
the folder created earlier (“Maps” in our example).
12.Click
File>Exit to quit the program. If you now have a look
into the “Maps” folder, you will see the following list of
files (still referring to our example):
– Map1.imd (map project description file)
– A_RFS20Lr1c1.bmp (1st bitmap file, 1st row, 1st
column),
