No, I had a play yesterday evening. Google Earth is easier. You'll need a graphics program like Irfanview.
Go to your home area in Google Maps. Put the pointer over your location and write down the geographical co-ordinates at the bottom of the screen. Remove all the names, roads etc as they just clutter things up. Expand the map to cover the area you want. Move the pointer to the top of the map and write down the co-ordinates, repeat for left, right and bottom.
Press "CTRL + Print Screen". Open Irfanview and press "CTRL V". Click and hold your mouse at the very top left of your map and drag across to the bottom right corner - you should have a square on your map. Click on Edit and select "Crop Selection" then "Files - Save as" and save it as "Card-1.GIF"
Open Acarsd and click on the Map button - proceed under 'define map settings' and put down those co-ordinates in the first column only, just the North for the top and bottom and the Wests for the left and right - just two decimal places is good enough. Enter West as a negative number. Put in your home location. Press save and it will prompt you for a file name - browse to your Acars directory and press save. Click on 'Maps" and see if it works. You may have to adjust your home location as it is often out due to non-linearities in the map.
