2. Texas Mapping Systems: Application and Dissemination of Big Data ž  Ecological Systems Project —  Background —  Methods —  Results ž  Application —  Species Habitat Modeling —  Conservation Opportunity Areas —  Riparian Conservation ž  Delivery —  Difficulties —  Professional Delivery —  TEAM Application ž  Questions
3. Background ž  GOAL- Better land cover for Texas —  Increase spatial resolution(10 m vs 30 m) and thematic resolution (18 classes vs 399 classes) —  Better accuracy (overall 85%) —  Better ecological interpretation ž  Multi-Agency, many Partners. —  MoRAP, University of Missouri —  TNC, Texas —  NatureServe, Southeast Region —  TNRIS —  NRCS, TXFS, USFS , & USFWS —  Private landowners others
4. Methods -Remote Sensing & Modeling
5. Field Data Phase 1 Phase 2 Phase 3 Phase 4 Phase 5 Phase 6 •  Sampled roadside, private & public land •  Dominant species, land cover types, and classes of % composition

7. Methods -Modeling
8. Results •  Higher Spatial Resolution •  polygons at 10m from resampled aerial imagery •  Higher Thematic Resolution •  398 types •  Field Collected Data •  >14,000 points collected •  Agreement with ground data •  74% to 90% •  Mapped 19 Invasive Types
9. ž  “Texas is a Big State” —  69,152,993 Hectares Mapped in Texas ž  398 Mapping Systems —  Row Crops 10.8% —  Native Invasive Mesquite 6.1% ž  Mapped types —  25 types made up > 1% Area —  95 types made up 0.1% -1% Area —  278 types made up <0.1% Area Results
10. Results 0 2 4 6 8 10 12 % Land Area of Texas Mapped Types Ordered by Area (Ha) % Area of Mapped Types 0 1 2 3 4 5 6 7 % of Total Field Data Collected % 0f Total Field Data Largest • Relatively small number of types contribute most to land area • 46 types=70% of the land area and contain 61% of the field data • While a large number of types make up a relatively small area of Texas • 281 types=5% of the land area and contain 10% of the field data Difficult to determine overall accuracy. Many of the mapped cover small areas and contain few field samples. Mapped Types Ordered by Area (Ha) Smallest Smallest Largest
