Geospatial Climate Models Show How Fire Seasons Are Changing

Changing technologies, including new satellite systems, and better climate and fire modeling, including the integration of these tools and data capture methods, will likely mean improved fire modeling in the future.

Elements of a Map

Maps are the primary tools by which spatial relationships are visualized. Maps therefore become important documents. There are several key elements that should be included each time a map is created in order to aid the viewer in understanding the communications of that map and to document the source of […]
