Most of the GIS’s recent growth has been in its
capabilities as a “technical tool” for corralling vast amounts of spatial
data and providing near instantaneous access to remote sensing images, GPS
navigation, interactive maps, asset management records, geo-queries and awesome
displays. In just forty years, GIS has
morphed from boxes of cards passed through a window to a megabuck mainframe
computer, to today’s sizzle of a 3D fly-through of terrain anywhere in the
world with back-dropped imagery and semi-transparent map layers draped on top—
all pushed from the cloud to a GPS enabled tablet or smart phone. What a ride!
However, GIS as an “analytical tool” hasn’t experienced the same
meteoric rise— in fact it might be argued that the analytic side of GIS has
somewhat stalled over the last decade.
But the future of GIS in forestry is moving
from a “down the hall and to the right” specialist’s role providing mapped
data, to a broader and more active role providing spatial information through
analysis and modeling that directly interacts with research, policy formation,
planning and management decisions. The
shifting emphasis from data–centric tools for mensuration (Where is What)
to application-specific constructs of prescriptive mapping (Why, So
What and What If) infuses
consideration of geographic patterns and relationships within problem-solving
contexts. The paradigm shift replaces
spatially-aggregated tools and models that assume uniform or random
distribution of typical conditions in geographic space, with spatial reasoning
and analytical procedures that capitalize on the variation within and among map
variables. The result is a “map-ematical” structure that enables resource professionals
from various disciplines to better understand and communicate complex spatial
interplay of edaphic, topographic, biological, ecological, environmental,
economic and social considerations. This
paper describes a comprehensive framework for grid-based map analysis and
modeling concepts and procedures as direct spatial extensions of traditional
mathematics and statistics enabling individuals with minimal or no GIS
background to develop spatial reasoning skills—thinking with maps.
