Table A-2. HydroPoint Class <br />Attribute Description Type <br /> Not populated -the reach concept does not apply to point <br />ReachCode data and inclusion on this attribute in documentation appears esriFieldTypeString <br /> to be an error. <br /> Unique identifier associated with descriptive feature type <br /> (e.g., Gate, Underpass, Well). A complete list of feature <br /> types and the corresponding delineation (i.e., point, line, <br />FType area) is provided in Appendix A of the NHD User's Guide esriFieldTypeInteger <br /> at http://nhd.usgs.gov/chapterl/chpl_data_users_guide.pdf <br /> (although this document was written for NHDInArc, the <br /> information also a lies to NHDInGeo). <br /> Unique five-digit code associated with text description that <br /> contains all feature characteristics and values. The general <br /> format of the feature code is FFFCC, in which FFF is the <br /> three-digit code for a feature type. CC is the two-digit code <br /> for a combination of values for characteristics associated <br /> with a feature type. If only the feature type is identified, <br /> these last two digits are assigned the value "0". For <br /> example, the feature type "Dam/Weir" has the three-digit <br /> identifier "343". This number serves as the first three digits <br />FCode of the feature code. A code of "34300" is used if no esriFieldTypeInteger <br /> characteristics are encoded for the feature. A feature <br /> classified as "Dam/Weir" also may have the characteristic of <br /> "Construction Material" with the values of "earthen" and <br /> "nonearthen" <br />and the characteristic of "Operational Status" <br /> , <br />with the values of "operational" and "under construction". <br /> The codes used to encode the combinations of values are: <br /> Dam/Weir Ouerational Status <br /> Operational Under Construction <br /> Earthen 34301 34302 <br /> Nonearthen 34303 34304 <br />Page 15 of 17 ~fifversFde TeChnnlo~yv ffTC. <br />4s':rkv Resuurce.s Ergmee: mg end ~C9 nsuNrng <br />
