USING MAPFIX

MapFix is a utility program supplied with SignalTrack used to convert the bitmap files of the maps

you've saved into map files that can be used with SignalTrack.

IMPORTING THE IMAGE

To import a graphics file containing a map image to Map Fix, select the Import option from the File

menu or click the Import button on the tool bar. A file open dialog appears. Then go to the

directory where the graphics file is located, select the file and click OK. The map image then appears

on the screen

ENTER CALIBRATION POINTS

Using commands in the Enter Points menu or on the tool bar, you assign coordinates to your pixel

image by specifying the latitude and longitude or MGRS coordinates of two locations on the image.

Thus, you need to know the location of two points that you can identify and select with the mouse.

You are free to choose any two points, except that they must define a rectangle (they cannot line

up). To achieve maximum precision, you should see to it that the two points are fairly far apart,

preferably along a diagonal of the image. The following commands appear in the Enter Points menu:

Fix Point 1: Determine the location and coordinates of the first point. When you select this option,

the cursor changes to a cross. Move the cross to the first location and click the mouse. Enter the

latitude and longitude or MGRS coordinates of the location in the dialog box that pops up. The

location you have chosen is marked in red on the screen. If you are not satisfied, select Clear

Point 1 from the Enter Points menu and repeat the process.

Fix Point 2: Determine the location and coordinates of the second point. When you select this

option, the cursor changes to a cross. Move the cross to the second location and click the

mouse. Enter the latitude and longitude or MGRS coordinates of the location in the dialog box

that pops up. The location you have chosen is marked in blue on the screen. If you are not

satisfied, select Clear Point 2 from the Enter Points menu and repeat the process.

Clear point 1 and Clear point 2: Use these options if you want to start over fixing points.
