|Title:||Federal Weather Radar Impact Zones|
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
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.

The attributes in this dataset are believed to be accurate.
|Horizontal Positional Accuracy:||
Maximum scale of intended use is 1:80,000.
Spatial and attribute properties are believed to be complete, although attribute information has been simplified. Geometric thresholds from original data are preserved. No tests have been completed for exhaustiveness.
These data are believed to be logically consistent. Geometry is topologically clean.

URL where the source data were originally accessed.
Original shapefiles were provided by ROC, and were combined and condensed by NOAA OCM.
Process Step 1
• Original source data was provided by NOAA Radar Operations Center • Import 4 shapefiles into a file geodatabase • Project 4 feature classes into NAD83 • Update attribute names to siteID and siteName • Add impactZone field to each feature class • Populate the fields so that GREEN = Notification Zone, YELLOW = Consultation Zone, ORANGE = Mitigation Zone and RED = No Build Zone • Dissolve each feature class based on siteID, siteName, and impactZone, unselecting multi-part features • Integrate each feature class at 1 foot tolerance to clean up most of the slivers in the data • Dissolve each feature class again based on siteID, siteName, and impactZone, unselecting multi-part features • Erase RED from ORANGE and Merge the new hollow ORANGE with RED • Union this new ORANGE-RED, and split and merge overlaps in the Mitigation Zone only • Erase the new ORANGE-RED from YELLOW and Merge the new hollow YELLOW with ORANGE-RED • Union this new YELLOW-ORANGE-RED, and split and merge overlaps in the Consultation Zone only • Erase the new YELLOW-ORANGE-RED from GREEN and Merge the new hollow GREEN with YELLOW-ORANGE-RED • Union this new GREEN-YELLOW-ORANGE-RED, and split and merge overlaps in the Notification Zone only • Delete from the No Build Zone features: Camp Humphreys, Kadena AB, Kunsan AB, Lajes AB and Langley Hill • Select by Attributes where siteID = 'PAHG', and populate so that all features have siteName = 'Kenai FAA (RDA1)' • Integrate new feature class at 20 feet tolerance to further clean up data slivers • Check geometry and project data into WGS 1984 Auxiliary Sphere
