Farm Site will work just fine for mapping field tiling. With Farm Site you can map out fields on one layer and then add a second layer that has the tiling on it. Additionally, with Farm Site if you would ever decide to use a GPS receiver to map tiling lines and/or field boundaries, you could use the Farm Site mobile program on a laptop computer that is hooked to a GPS receiver to map the tiling lines and/or field boundaries. With Farm Site you can also import USGS roads & waterway files that are available at no charge from the internet. This allows you to have all the roads and waterways that you need mapped for you as a starting point.
