3 (Nanotechnology) Geotechnology (Biotechnology) GPS/GIS/RS Modeling involves analysis of spatial relationships and patterns (numerical analysis) PrescriptiveModeling Mapping involves precise placement (delineation) of physical features (graphical inventory) DescriptiveMapping Geotechnology is one of the three "mega technologies" for the 21st century and promises to forever change how we conceptualize, utilize and visualize spatial relationships in scientific research and commercial applications (U.S. Department of Labor) Why So What and What Global Positioning System (location and navigation) Geographic Information Systems (map and analyze) Where is What (Berry) Remote Sensing (measure and classify) The Spatial Triad

4 Historical Setting and GIS Evolution Spatial Database Management links computer mapping techniques with traditional database capabilities (80s) Multimedia Mapping full integration of GIS, Internet and visualization technologies (00s) Map Analysis representation of relationships within and among mapped data (90s) Computer Mapping automates the cartographic process (70s) Geotechnology (GPS, GIS, RS) DIGITAL Manual Mapping for 8,000 years ANALOG Focus of this presentation (Berry)

10 Erosion_potential Streams Erosion Buffers Distance Distance away from the streams is a function of the erosion potential (Flow/Slope Class) with intervening heavy flow and steep slopes computed as effectively closer than simple distance— “as the crow walks” Calculating Effective Distance (variable-width buffers) Effective Buffers (digital slide show VBuff) VBuff Effective Erosion Distance CloseFar Heavy/Steep (far from stream) Light/Gentle (close) Simple Buffer (Berry)

12 GeoExploration vs. GeoScience Continuous Spatial Distribution Discrete Spatial Object Map Analysis Geographic Space Map Analysis map-ematically relates patterns within and among continuous spatial distributions (Map Surfaces) — spatial analysis and statistics (GeoScience) (Geographic Distribution) Average = 22.0 StDev = 18.7 Desktop Mapping Data Space Field Data Standard Normal Curve Desktop Mapping graphically links generalized statistics to discrete spatial objects (Points, Lines, Polygons) — non-spatial analysis (GeoExploration) X, Y, Value Point Sampled Data (Numeric Distribution) “Maps are numbers first, pictures later” 22.0 Spatially Generalized Spatially Detailed 40.7 …not a problem Adjacent Parcels High Pocket Discovery of sub-area… (See Beyond Mapping III, “Epilog”,, www.innovativegis.com/basis ) (See Beyond Mapping III, “Epilog”, Technical and Cultural Shifts in the GIS Paradigm, www.innovativegis.com/basis )(Berry)

13 Spatial Interpolation (Smoothing the Variability) The iterative smoothing process is similar to slapping a big chunk of modeler’s clay over the “data spikes”… …repeated smoothing slowly “erodes” the data surface to a flat plane = = AVERAGE (digital slide show SStat2) SStat2 …then taking a knife and cutting away the excess to leave a continuous surface that encapsulates the peaks and valleys implied in the original field samples (Berry)

14 Visualizing Spatial Relationships What spatial relationships do you SEE? …do relatively high levels of P often occur with high levels of K and N? …how often? …where? Phosphorous (P) Geographic Distribution Multivariate Analysis— each map layer is a Multivariate Analysis— each map layer is a continuous variable with all of the math/stat continuous variable with all of the math/stat “rights, privileges and responsibilities” therewith …simply “spatially organized “ sets of numbers (matrix) “rights, privileges and responsibilities” therewith …simply “spatially organized “ sets of numbers (matrix) “Maps are numbers first, pictures later” (Berry)

15 Calculating Data Distance …an n-dimensional plot depicts the multivariate distribution— the distance between points determines the relative similarity in data patterns PythagoreanTheorem 2D Data Space: Dist = SQRT (a 2 + b 2 ) Dist = SQRT (a 2 + b 2 ) 3D Data Space: Dist = SQRT (a 2 + b 2 + c 2 ) Dist = SQRT (a 2 + b 2 + c 2 ) …expandable to N-space …this response pattern (high, high, medium) is the least similar point as it has the largest data distance from the comparison point (low, low, medium) (See Beyond Mapping III, “Topic 16”, Characterizing Spatial Patterns and Relationships, www.innovativegis.com/basis) (See Beyond Mapping III, “Topic 16”, Characterizing Spatial Patterns and Relationships, www.innovativegis.com/basis)(Berry)

16 Clustering Maps for Data Zones Groups of “floating balls” in data space identify locations in the field with similar data patterns – data zones or Clusters …data distances are minimized within a group (intra-cluster distance) and maximized between groups (inter-cluster distance) using an optimization procedure (See Beyond Mapping III, “Topic 7”, Linking Data Space and Geographic Space, www.innovativegis.com/basis) (See Beyond Mapping III, “Topic 7”, Linking Data Space and Geographic Space, www.innovativegis.com/basis) (See Beyond Mapping III, “Topic 16”, Characterizing Spatial Patterns and Relationships, www.innovativegis.com/basis) (See Beyond Mapping III, “Topic 16”, Characterizing Spatial Patterns and Relationships, www.innovativegis.com/basis)(Berry)

This map is yield variation every few feet. This map is 4) combined with soil, terrain and other maps to 4) combined with soil, terrain and other maps to derive 5) a “Prescription Map” that is used to derive 5) a “Prescription Map” that is used to 6) adjust fertilization levels every few feet 6) adjust fertilization levels every few feet in the field (variable rate application). in the field (variable rate application).

24 Dominant Human Forces (three game changers) #1 The “-ists” and the “-ologists” — a continuing “Tool” versus “Science” dichotomy of perspective of what GIS is and isn’t #1 The “-ists” and the “-ologists” — a continuing “Tool” versus “Science” dichotomy of perspective of what GIS is and isn’t The “-ists” focus a GIS specialist’s command of the tools needed to display, query and process spatial data. The “-ologists,” focus on users (e.g., ecologists, sociologists, hydrologists, epidemiologists, etc.) who understand the science behind the spatial relationships. The “-ists” focus a GIS specialist’s command of the tools needed to display, query and process spatial data. The “-ologists,” focus on users (e.g., ecologists, sociologists, hydrologists, epidemiologists, etc.) who understand the science behind the spatial relationships.
