Thought Questions?➲ Are defense geospatial software requirements
typical?➲ Can the marketplace guarantee software that
meets defense needs will be developed?➲ Can the marketplace guarantee that software
will be supported?➲ Is geospatial software a commodity of can it
provide a strategic advantage?➲ What are the benefits and costs of a diverse
software ecosystem?
