Description:
Abstract: 1:24000 hydrography of the State of Kansas developed from 1:12000 USGS DOQ's, based on 7.5 quadrangles and updated with DOQ's. The data set was developed based on the extent and horizontal placement of USGS 7.5 minute quadrangles and then revised water bodies and horizontal placement from 1:12000 USGS DOQ's.
Purpose: This data was complied to develop a hydrography dataset that would be entered into the National Hydrographic Database (NHD) and then become part of the National Spatial Dataset Infrastructure's (NSDI) framework dataset. The data would then be used and maintained through cooperative efforts with the Kansas GIS Policy Board.

Attribute_Accuracy:
Attribute_Accuracy_Report: Attribute Accuracy is tested by manual comparison of the source with hard copy plots and Digital Ortho Quads (DOQ) and/or symbolized display of the digital line graph on an interactive computer graphic system; selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen. All attribute data conform to the attribute codes current as of the date of digitizing as described in Part 3: Attribute Codes in "Standards for Digital Line Graphs", National Mapping Program Technical Instructions, USGS.
Logical_Consistency_Report: Data set was checked and corrected for overshoots and undershoots, polygons under 250m sq, double lines, intersection errors, multiple labels, pseudo nodes, stream direction, edgematched to 7.5 quad format. The neatline is generated by connecting the four corners of the digital file, as established during initialization of the digital file. All data outside the enclosed region are ignored and all data crossing these geographically straight lines are clipped at the neatline. Neatlines were straightened to a .6m threshold between 7.5 quad tics. The following tolerances were used: snap tolerance: 1m fuzzy tolerance: 1m dangle tolerance: 3m weed tolerance: 1.5m line, node and polygon topology was created.
Completeness_Report: All Data was digitized at a 1:4800 scale. Placement and extent of hydrology was determined from USGS 7.5 quadrangle sheets. Extent was not edited, only horizontal placement. Water bodies were added and deleted as shown on 1:12000 DOQ's. Only hydrologic features that were readily identifiable at 1:12000 scale on USGS 1:12000 DOQ's were digitized Generalization tolerance's: Weed = 1 meter, Fuzzy = 1 meter, Dangle = 3 meter, and Snap Distance = 5 meters.

Process_Step:
Process_Description: Using either Kansas Geological Survey's (KGS) digital line graph (DLG)--for UTM or standard USGS 7.5 minute quadrangle's as backdrop for extent, streams were digitized off of 1:12000 DOQ's. Only stream placement was digitized. Care was taken to ensure that stream direction was taken into account when digitizing. The only extent that was updated from the backdrop was disappearing streams. All disappearing streams that are contained in the backdrop, but contained a definite drainage channel on the DOQ, were connected to the major stream. If there was any question as to stream placement, the backdrop was strictly adhered to. Double line streams were digitized off of the backdrop even if streams were covered with trees. Double line streams were attributed according to stream direction either as the left bank or the right bank. Double line streams next to the state line were digitized as one bank (according to direction) with a digitized center line (attributed as perennial), in order to close the polygon. Sandbar islands were not digitized, but shallow sandbars were included as part of the stream channel. All islands that could be seen at a 1:4800 scale on the DOQ's were digitized and attributed as perennial. All ponds, that could be seen at a 1:4800 scale on the DOQ's and were greater that 0.5 acres, were digitized. Ponds that were on the backdrop, but could not be seen on the DOQ's were not digitized. Ponds were digitized, off of DOQ's, at their perennial water level. Sewage lagoons were digitized off of DOQ's at a scale of 1:4800. The lagoons were labeled as man-made and were coded as lagoon. Agricultural waste systems were digitized if there was a distinct, confined livestock area with a defined lagoon structure. Agricultural waste ponds were coded as man-made and labeled as lagoon. Quarry's were digitized if there was either: a distinct environment conclusive to quarry's, as seen on the DOQ's, or after referring to USGS 7.5 minute quadrangles and the area in questions had at one time contained a quarry. Quarry's were coded as man-made and were labeled as water. Industrial ponds were digitized, if they are contained in an urban, industrial environment. Industrial ponds were coded as man-made and labeled as water. Road ditches were digitized if backdrop included the ditches in their layer. Canals were digitized if backdrop was conclusive to a stream. Wetlands were not digitized unless specifically displayed on USGS 7.5 quadrangles as a large, contiguous wetland with a size greater than 0.5 acres. Wetlands were coded as natural and labeled as water. The stream digitizing was documented in the following ways: backcover quadrangle date and photo revision data, digitized completion date, and estimated time of completion. All hydrography was check plotted at the 7.5 quad format and was overlaid on USGS 7.5 quadrangle sheets to ensure: hydrography placement, hydrography direction, and hydrography type. Through on screen checks the following were checked: edge match problems, dangles, pseudo nodes, sliver polygons, multiple labels, and built topology. All quads were spot checked by an inner office review. Automated procedures checked for the following errors: polygon, and line topology, multiple label points within a polygon, unlabeled polygons, pseudo nodes, dangling nodes, sliver polygons, and edge matching.

Entity_and_Attribute_Information:
Overview_Description:
Entity_and_Attribute_Overview: DLG3 attribute codes are used to describe the physical and cultural characteristics of DLG node, line, and area elements. Attribute codes are used to reduce redundant information, provide enough reference information to support integration with larger databases, and describe the relationships between cartographic elements. Each DLG element has one or more attribute codes composed of a three digit major code and a four-digit minor code. For example, with the 1: 24,000-scale DLG data, the line attribute code 050 0412 has a major code (050), meaning hydrography, with a minor code (0412) meaning stream. Area Attributes: 050 0109 Sewage Lagoons, 050 0421 Lake or Pond. Arc Attributes: 050 0200 Natural shoreline, 050 0201 Manmade shoreline, 050 0412 Stream, 050 0414 Ditch or Canal, 050 0610 Intermittent streams, 050 0605 Right bank of double line stream, 050 0606 Left bank of double line stream.
