Texas statewide stream and water features. Dataset is adapted from the National Hydrography Dataset. Dataset is intended for planning and cartographic purposes only, not suitable for modeling.
This dataset has been adapted for use as a cartographic and planning layer. The dataset has been simplified to a set of stream types that can be easily filtered using STRM_TYPE or the DISPLAY and DISPLAY_ALT fields. All geometric alignments are derived from the NHD dataset. <div><br /></div><div><b>Stream Type Domains</b></div><div>1 - Major River</div><div>2 - Flowing Stream</div><div>3 - Intermittent Stream</div><div>4 - Bayou</div><div>5 - Ditch</div><div>6 - Canal</div><div>7 - River</div><div>8 - Coastline</div><div>9 - Other (Includes underground pipelines)</div><div><br /></div><div><b>Filters and Queries</b></div><div>Data can be filtered based on need either by the STRM_TYPE column or through two display columns. </div><div><br /></div><div>DISPLAY allows the user to granularly filter by major and flowing water sources and/or intermittent water features. </div><div><i>DISPLAY = 1 </i>will return all flowing water features. </div><div><i>DISPLAY = 0</i> will return all intermittent features. </div><div><i>DISPLAY is not null </i>will return all cartographic water features. </div><div><br /></div><div>DISPLAY_ALT allows the user to filter for large scale and small scale views of the data. </div><div><i>DISPLAY_ALT = 1</i> will return all major water features and flowing streams, canals, and bayous and should be used for small scale maps. </div><div><i>DISPLAY_ALT = 0</i> will return intermittent streams and minor canals. </div><div><i>DISPLAY_ALT is not null </i>will return all cartographic water features and should be used for large scale maps. </div><div><br /></div>
