When you are not using a license, the functionality of the SDK is limited (for example, you can only load one layer at a time.) By getting a license, you will enable all Global Mapper SDK functionality. You can get a Developer license, which would allow you to write and test your program, but your program cannot be distributed. For details about pricing, and to find out what options you have as a student developer, contact sales@bluemarblegeo.com.
