This is a set of digital maps of cycle 2 LUS, MAS and PAS boundaries. Purpose: The purpose of this data set is to describe the hydrogeologic units and predominant land uses that the NAWQA study units used for selecting wells for their LUS and MAS ground-water sampling networks. The boundaries will be the basis for computing nationally consistent GIS ancillary characteristics for the ground-water studies, which will be used in the analysis of water quality data. Supplemental_Information: DATA FORMAT The boundaries are in ARCGIS coverage format. NAMING CONVENTION The coverage naming convention is netcode_bnd (for example, LUSCR1_BND), or netcode_trg (for example LUSCR1_TRG). The BND coverages represent the entire areal extent of the hydrogeologic unit defined for study, for example, a major aquifer. The TRG coverages represent the targeted land use within the overall area described by the BND coverage. The targeted land use coverage is supposed to nest within the overall boundary coverage, but this is not always the case. COVERAGE DOCUMENTATION The coverages have an ascii metadata file named "covername.met" that contains information regarding each particular coverage. A metadata.xml file also is present in the coverage folder. Some of the coverages are copies of those that were collected during cycle 1 and might have the old-style document.aml metadata. The old-style metadata is in INFO files called "covername.nar," "covername.ref," "covername.att," and "covername.doc." For the most part, the boundaries for studies being resampled in cycle 2 are the same as the corresponding boundaries for cycle 1. Some exceptions are listed below. CHANGES SINCE CYCLE 1 The boundaries for acfbluscr3, acfbsus1, albelusag1, nvbrsus2, trinsus3, sanjluscr1a, and sanjlusor2a changed from cycle 1 to cycle 2. GAFL supplied higher resolution boundaries for gaflluscr1. CHECKS APPLIED TO THE COVERAGES We plotted the ground-water study boundary submitted by the study units and the wells in the NAWQA data warehouse for each ground-water network to make sure that most of the wells fell within the study boundary and that the wells were distributed throughout the study area. If necessary, we renamed coverages to match the appropriate network codes and to match the type of boundary represented, either BND (overall area) or TRG (targeted land use). We checked the coverages using checkdata.aml and the metadata using the MP metadata parser. We corrected some of the errors discovered by checkdata, such as missing polygon labels and small dangling arcs. However, checkdata still reports some errors such as multiple labels in a polygon in a few of the coverages. Many of the metadata files still produce errors despite the efforts to have them corrected. To accommodate the NAWQA data warehouse requirements for one data record per ground-water polygon, we duplicated some of the coverages. For example, if the overall areal extent of a land use study was the same as the major aquifer study boundary, we have two identical coverages, one for the overall boundary of the land use study and one for the boundary of the major aquifer study. Analysts should keep this in mind when compiling ancillary data or analyzing water quality data to avoid double counting. ADDITIONAL NOTES: NACP submitted two pas1a_bnd coverages - these area named pas1a_bnd and pas1a_trg. pas1a_bnd is the aquifer coverages and pas1a_trg is the area of the aquifer that was the targeted area. Sample.aml cells for LUS, MAS and PAS were requested during the Winter 2011 and Fall 2012 data request, are now part of this data set. When available they are listed below.

Overview_Description: Entity_and_Attribute_Overview: Each boundary coverage has a field called SUCODE. Any fields besides SUCODE usually are ignored. SUCODE is the combination of the 4-letter abbreviation for the NAWQA study unit plus the ground-water study network code (NETCODE). For example: spltluscr1. When using the coverages, any interior polygon that has a valid SUCODE is considered to be INSIDE the ground-water study area. When analyzing data using the coverages, EXCLUDE the polygons that have a blank value for SUCODE. Any interior polygon that has a blank value for SUCODE is OUTSIDE the ground-water study. Entity_and_Attribute_Detail_Citation: Valid SUCODEs can be determined using the NAWQA data dictionary.
