Summary
This feature class is a component of
TPWD 'base' data. 'Base' data includes current, statewide geospatial information
intended to provided context for mapping purposes.The Coastal Fisheries Division
used this feature class to provide better resolution for mapping harvest
monitoring database.
Description
This feature class defines minor bays along the Texas Gulf Coast.

SURVEYED PRODUCT. Title 1 Part 10 Chapter 201 Rule §201.6 of the Texas
Administrative Code suggests data showing the full extent of Texas be projected
in the Texas State Mapping System. This feature class as provided by TPWD is
unprojected.Note that this data is not intended for navigational use. The
original intention of this data set is to display harvest monitoring database
query results.
Selected arcs out of primary source coverage (esi-beg(nwi)) that composed minor bays in CF-TPWD operations manual. If a minorbay was not present in the primary coverage, then secondary coverages were referred to in this order: TxDOT, NOAA, USGS, DOQQ, TPWD counties layer. Each minorbay's boundary was selected from it's parent coverage, then was edited and built to form a polygon. Then appended to and attributed. This is revision number 2. The 1st was flawed because many contiguous polygons were not represented as such. Revisions by Ashley Summers used the TPWD counties layer from 2004 to determine the outline of missing bay area in the Upper Laguna Madre. Reviews_Applied_to_Data Two interns performed the initial revisions. These were verified or corrected.
