The ability to easily add, edit and manipulate data with the spot map builder. I was able to create custom maps in minutes rather than days. There are some limitations with some of the tools available. For example, you can't change certain properties like colors, line styles or font sizes without creating new layers which requires extra time. In order to be able to easily create custom maps for my work, I would recommend this software to others. It allowed me to quickly and efficiently produce custom maps.
