VRI Data Reconciliation or The Hard Part of the Workation

Transcription

1 River Management Symposium/ National Outdoor Recreation Conference Boise 2016

2 VRI Data Reconciliation or The Hard Part of the Workation Workation /wurk-key-shuh n/ Noun 1. What my wife thinks about the field work I do. 2. Performing a Visual Resource Inventory

3 Field Data Maps, Maps, & MORE Maps! Draft maps Travel Recreation Many MORE!!!

4 Field Data Logs, Pamphlets, & Notes, OH MY! Scenic Quality Sensitivity

5 Field Data More Photos Than your Aunt Myrtle s Vacation IOP Inventory Observation Point RPP Remote Protocol Photos POP Photo Observation Point

6 GIS Taming the Field Work Lion Large Part of Performing a VRI Massive Amount of Related Data Sets Final Deliverable GIS: Geographic Information Systems

7 GIS Scenic Quality Rating Units (SQRU) SQRU Polyline Digitization The BULK of the GIS Work Based on Physical Characteristics from draft SQRU Maps 1:24K Polyline has Feature Data and Source Why that line is there? Where that line came from? SQRU Polygon Population Create polygons Populate polygons Rating Landscape Character

8 GIS Scenic Quality Rating Units (SQRU) SLRU Polyline CREATION Shapefiles Parks NCA, ACEC, etc. Viewsheds Scenic Byway Overlooks Information provided by BLM Data collected in-field/online Polyline has feature data and source Why that line is there? Where that line came from? Polygon Population Sensitive Level Rating Resolve Overlapping Areas

9 GIS Inventory Observation Points Import points Process Panoramic(s) Link to SQRU one too many

10 GIS Distance Zones Select Viewing Platforms Major Roads, Highways, Scenic Byways, etc. BLM Staff Input Viewsheds 15 Miles Clipped To 0-5 miles 5-15 miles

11 GIS VRI Classes Union SQRU, SLRU, DZ Datasets GIS VRI Classes Utilize Matrix to Assign Classes Map for As Inventoried Map for With VRI I Classes

12 GIS Other Tasks Load Interim Data into Geodatabase (GDB) Provides History of Process Populate Metadata in GDB Provides Info on Who, What, When Perform ESRI Data Reviewer on GDB Checks Topology of Lines and Data Table Accuracy VRI Acreage Legend AKA McCarty Super Legend Shows Relationship and Percentages Between Datasets

13 Final Thoughts on GIS & VRI Start Now Data Collection Elevation Data Shapefiles Road/Travel Networks Etc. Viewshed Modeling Run Low Hanging Fruit Get Approved Viewing Platforms ASAP Do Stay Organized Solid QA/QC Process Communicate Deadlines with Client on Data Collection And Remember..

14 KEEP CALM AND DIGITITZE ON

20 Value of the VRI UTILIZATION Management decisions (VRM Class Objectives) Distribution of and effects on the VRI factors (scenic quality, distance zones, public sensitivity and scarcity) Current quality and condition of the visual resource values. (how much of the public landscape is visually altered) The visual integrity of the landscape s intact natural character. (severity of visually alteration) Trends in human alteration of the landscape character. (in decline, stable, or improving, and places to be rehabilitated) Public issues regarding visual modification to the natural landscape character.

21 Value of the VRI Another Value of Inventories Relevant to establishing an inter-agency dialogue about visual condition of the landscape Enjoying the view is to observe a visual composite of our land use decisions
