Item Identification

Title: Weather Radar Impact Zones
Status: Completed
Publication Date: 2015-09-01
Abstract:

These data represent an inventory of the national impacts of wind turbine interference with NEXRAD radar stations. This inventory was developed by the NOAA Radar Operations Center (ROC) to establish variable zones that delineate the possible impacts that wind turbines may have on radar operations. The inventory scheme includes four zones that take in to account terrain, distance, and the number of elevation angles impacted. ROC requests various degrees of consultation with the developer depending on the zone. No Build - No wind turbines permitted Mitigation Zone - Significant impacts likely Consultation Zone - Significant impacts possible Notification Zone - Impacts not likely

Purpose:

To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.

Process Steps

Process Step 1

CC ID: 868744
Description:

1) Original source data was provided by NOAA Radar Operations Center

2) Import 4 shapefiles into a file geodatabase

3) Project 4 feature classes into NAD83

4) Update attribute names to siteID and siteName

5) Add impactZone field to each feature class

6) Populate the fields so that GREEN = Notification Zone, YELLOW = Consultation Zone, ORANGE = Mitigation Zone and RED = No Build Zone

7) Dissolve each feature class based on siteID, siteName, and impactZone, unselecting multi-part features

8) Integrate each feature class at 1 foot tolerance to clean up most of the slivers in the data

9) Dissolve each feature class again based on siteID, siteName, and impactZone, unselecting multi-part features

10) Erase RED from ORANGE and Merge the new hollow ORANGE with RED

11) Union this new ORANGE-RED, and split and merge overlaps in the Mitigation Zone only

12) Erase the new ORANGE-RED from YELLOW and Merge the new hollow YELLOW with ORANGE-RED

13) Union this new YELLOW-ORANGE-RED, and split and merge overlaps in the Consultation Zone only

14) Erase the new YELLOW-ORANGE-RED from GREEN and Merge the new hollow GREEN with YELLOW-ORANGE-RED

15) Union this new GREEN-YELLOW-ORANGE-RED, and split and merge overlaps in the Notification Zone only

16) Delete from the No Build Zone features: Camp Humphreys, Kadena AB, Kunsan AB, Lajes AB and Langley Hill

17) Select by Attributes where siteID = 'PAHG', and populate so that all features have siteName = 'Kenai FAA (RDA1)'

18) Integrate new feature class at 20 feet tolerance to further clean up data slivers

19) Check geometry and project data into WGS 1984 Auxiliary Sphere
