Spatial data are important to scientific studies and research. They are the raw pieces of information that inform us about the processes involved in many fields. Scientists involved in oceanography, forestry, soil science, energy, human geography, health, transportation, urban planning and many other field collect, manage, process and visualize both simple and complex processes using spatial information. In many cases we find that these activities using both commercially available tools and freely available tools. In some cases, due to the nature of the work under study, specially designed and programmed software tools and technologies are developed that enable the active pursuit of spatially related data and methodologies.
