Description:
Abstract:

The NHDPlusV2 NLCD 2011 Land Use Extension contains the NLCD 2011 land use categories allocated to NHDPlusV2 catchments and accumulated down the network. The data consists of three comma delimited text files for each NHDPlusV2 Vector Processing Unit (VPU): (1) catchment allocated attributes, (2) total upstream accumulated attributes, (3) divergence routed accumulated attributes.
Purpose:
This data provides additional attributes to the NHDPlusV2 spatial data.
Supplemental_Information: For more information about NHDPlusV2, refer to the NHDPlusV2 Users Guide.

Provided the land use characteristics that are allocated to NHDPlusV2 catchments.
Process_Step:
Process_Description: NHDPlusV2 Catchment Allocation and Accumulation Tool (CA3TV2)was used to allocate the NLCD 2011 land use chacteristics to the NHDPlusV2 Catchments. The allocation results were then accumulated using CA3TV2. There are 3 output files for each VPU: (1) catchment allocations are in IncrNLCD2011.txt, (2) total upstream accumulations are in CumTotNLCD2011.txt (3) divergence routed accumulations are in CumDivNLCD2011.txt. Each output file contains a Header line with a list of fieldnames for the data in the file:
[comid or featureid],MissDataA,attrvaltype1,attributevalue1, ..., attrvaltypeN,attributevalueN,hydroseq
Each line following the header line will contain actual data for a single NHDFlowline feature or a single Catchment:
In the output from the CA3TV2 Allocation function, the MissDataA field contains the area of the catchment (in square kilometers) that was valued as “NoData” in the input attribute raster. In the output from the CA3TV2 Accumulation function, the MissDataA field contains the total upstream accumulation of the allocated MissDataA fields.
Attrvaltype is a coded attribute that describes what type of value is contained in the immediately following attribute. The valid codes for Attrvaltype are:
A = value is an area in square kilometers
P = value is an area-weighted percent
X = value is a maximum
N = value is a minimum
V = value is an average
S = value is a sum
Attributevalue is the field name for the field that contains the actual value for the attribute.
The Hydroseq field is the hydrologic sequence number of the NHDFlowline that can be found in the \NHDPlusAttributes\PlusFlowlineVAA.Hydroseq field. In addition to containing this field, the records are ordered descending by Hydroseq.
The fields in the NLCD allocation and accumulation files contain "NLCDnn" where the nn is the NLCD category.
