CREATING A MAP IMAGE

To make a map you first need a graphics file containing a map image. You cannot use MapFix to

create this file. A convenient way of making a graphics file is to use a map program (see "Using

Microsoft MapPoint" on page 12). Alternatively, you could scan in an image from a hard copy map

or obtain one from a web site such as Google Earth or Google Map. You can even use a photograph

of a map if you would like. Since graphics files consume space on your hard disk, you might want to

delete them after you have used them to make SignalTrack maps.

GRAPHICS FILE FORMATS

There are a great number of file formats for storing images. Almost all of these are pixel based. A

given format can usually store several kinds of images (different numbers of colors per pixel and

different compression schemes). It is also possible to store an image as graphics drawing commands

(the Windows Metafile Format is of this type). Map Fix only handles can open JPEG (.jpg), bit map

(.bmp). or GIF (.gif) files. Common programs such as Microsoft Paint or Microsoft Imager can easily

convert any standard graphics file into a suitable image.

SCANNING IN AN IMAGE

If you create a map image by scanning it in from an image on paper, make sure that you orient the

paper image with north in the upward direction, so that latitudes become horizontal and longitudes

vertical. If the latitude and longitude lines on your map are not clearly visible make sure to mark the

latitude and longitude of two points on your map (preferably near diagonal corners). You then use

your scanning software to save the image as a graphics file.
