<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>This dataset contains the boundaries of current and historical agricultural fields within the State of Nevada. These data were generated by the Desert Research Institute using publicly available field boundary datasets collected from academic research teams, state and federal agencies, and the 2008 USDA Common Land Unit (CLU) database. In many cases, these datasets have been modified to remove redundant polygons, as well as small slivers and large polygons associated with grazing on non-irrigated rangelands and shrublands. Priority was given to more recent field boundary datasets produced by state and local agencies, and the modified CLU data were used only in cases where no state or local level datasets are publicly available.</SPAN></P><P><SPAN>Crop type information is derived from publicly available datasets, which often lag 6-12 months or more behind the current growing season, and thus may not always accurately reflect the current crop. The USDA Cropland Data Layer is used to derive crop type information for the majority of states. </SPAN></P><TABLE><TBODY><TR><TD><P STYLE="font-weight:bold;"><SPAN STYLE="text-decoration:underline;">Attribute Name</SPAN></P></TD><TD><P STYLE="font-weight:bold;"><SPAN STYLE="text-decoration:underline;">Explanation</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>OPENET_ID</SPAN></SPAN></P></TD><TD><P><SPAN>Unique ID assigned to each field</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>BasinID</SPAN></SPAN></P></TD><TD><P><SPAN>Nevada Hydrographic Basin ID</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>BasinName</SPAN></SPAN></P></TD><TD><P><SPAN>Nevada Hydrographic Basin Name</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>Notes</SPAN></SPAN></P></TD><TD><P><SPAN>Notes</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>Acres</SPAN></SPAN></P></TD><TD><P><SPAN>Field boundary acreage</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>CROP_[YEAR]_NDWR </SPAN></SPAN></P></TD><TD><P><SPAN>Cropland data layer (CDL) classification for the given year</SPAN></P></TD></TR><TR><TD><P><SPAN><SPAN>irr_[YEAR]</SPAN></SPAN></P></TD><TD><P STYLE="margin:1 1 1 0;"><SPAN>Irrigation status produced by IrrMapper (0-1)</SPAN></P></TD></TR></TBODY></TABLE><P><SPAN /></P></DIV></DIV></DIV> |
