 The following range and codeset fields: QZONE, LOCSTATE, TOWREG contain the value “NA” or "N/A" as a valid value that denotes missing data that was not present in the source data. However, the missing data may be present in other sources not yet discovered and used in the creation and/or maintenance of this dataset. These records may be populated with valid information in future update cycles. Caution should be exercised by the user of this feature class. This feature class does not contain fields of attribution for MEDS attributes of ADDRESS2, ZIP, ZIP+4, TELEPHONE (non-PII general switchboard phone number), and COUNTY FIPS. The following fields are only partially populated with actual values beyond “NOT AVAILABLE” (or blank): QZONE: 0.3% (this is likely a correct population of the value, but this cannot be adequately determined on the lack of adequate explanation in the metadata), LOCADD: 82%, LOCCITY: 92%, TOWREG: 7%, STRUCTYPE: 52%, SUPSTRUC: 61%, ALLSTRUC: 59%, NEPA: 59%. LOCADD information is largely directional or locational, rather than an actual address. Additionally, there are numerous points that are likely erroneously located. If you are using this dataset as a shapefile, please be aware that it was converted from a Geodatabase. As a result, this shapefile may have attribution and metadata errors resulting from the conversion process. The following are known issues: null values may have been changed to 0s (zeros) or to blank values, numbers (including latitude and longitude) may have been rounded up or down, there may be issues with Unicode character strings, and time cannot be stored in a date field. Field names may have been truncated to no longer than 10 characters or completely changed, lengthy string attributes may have been truncated to 254 characters, and attribute columns may have been deleted. Shapefiles do not support coded domains and subtypes therefore the original file geodatabase attribution and metadata information for coded domains and subtypes could be incorrect or missing in the shapefile version.

Level of the data: dataset

Lineage:

Process step:

Description: Updated LAT_DMS for OID = 244119 from 93,0,0 to 39,0,0 to align it with many point generalized to that location and to give it a valid LAT_DMS value. Updated OID = 281037 to align the LAT_DMS value to a north value. Standardized capitalization, abbreviations, and spelling for many LOCCITY attributes. Moved address information from LOCCITY to LOCADD. Updated LOCCOUNTY and LOCSTATE blank values to actual values, where available. Standardized capitalization and some abbreviations in the LOCADD field. NOT AVAILABLE, NA, and N/A populated for: LOCADD, LOCCITY, LOCCOUNTY, LOCSTATE, NEPA, QZONE, TOWREG, STRUCTYPE.
