Metadata Summary

Originator Mid-Minnesota Development Commission
Abstract The Drainage Ditch Inventory layer contains line features that display the surface drainage ditch system and the subsurface drainage ditch system (tile) of Kandiyohi County. The layer was created using the 2003 Farm Service Agency (FSA) Aerial Photography and the most accurate information from scanned georeferenced ditch maps provided by the county.

Title Drainage Ditch Inventory - Kandiyohi County, Minnesota 2004
Abstract The Drainage Ditch Inventory layer contains line features that display the surface drainage ditch system and the subsurface drainage ditch system (tile) of Kandiyohi County. The layer was created using the 2003 Farm Service Agency (FSA) Aerial Photography and the most accurate information from scanned georeferenced ditch maps provided by the county.
Purpose The data set was developed to have a digital inventory of the drainage ditch system in Kandiyohi County. Size of ditch and tile are included when data was available.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Visual comparison of ditch location and size were verified against the originial ditch maps produced by the engineers for the project.
Logical Consistency All lines are connected where intended. Data is topologically correct where intended.
Completeness All ditch information shown on ditch maps was added
Horizontal Positional Accuracy Surface data is as accurate as the 2003 FSA Aerial Photography. Lines were digitzed based on determining location from paper ditch maps and digitizing the features on the aerial photo. Subsurface ditch lines are as accurate as the georeferenced ditch maps. RMSerror is between 1 and 25 but on average about 10 for rectifying.
Lineage The Drainage Ditch Inventory layer contains line features that display the surface drainage ditch system and the subsurface drainage ditch system (tile) of Kandiyohi County. The source information comes from aerial photos, original ditch maps, and a larger ditch map showing all ditches located in Kandiyohi County. The layer was created using the 2003 Farm Service Agency (FSA) Aerial Photography and the most accurate information from scanned georeferenced ditch maps provided by the county. The scanned ditch maps, after scanned in, were georeferenced to their location. Visual location of the surface ditches was digitized off the aerial photo and verified off the scanned ditch maps. Tiles or subsurface ditches were digitized off the scanned ditch maps and visually checked to aerial photos where possible.

Entity and Attribute Overview The Kandiyohi Drainage Ditch Inventory features described in this database are represented as attributed lines and label points. The following information is included for each line:

Ditch Number [DITCH_NO]
Ditch Code [DITCH_CODE]
Account Number [ACCT_NO]
Ditch Jurisdiction [DITCH_JURI]
Ditch Type [DITCH_TYPE]
Branch Name [BRANCH]
Lateral Name [LATERAL]
Fork [FORK]
County [COUNTY]
Township [TOWNSHIP]
Range [RANGE]
Section [SECTION}
Quarter Section [QUARTER_QT]
Length [LENGTH]
Ditch or Tile Size [SIZE]
Source of Digitizing [DGTZ_SRCE]
labeling [LABELED]

The Ditch Number, Ditch Code, and Account Numbers are based on Kandiyohi County's codes for their tax system. Ditch Jurisdiction is whether it is a County or Judicial Ditch. The length is calculated based on feet and calculated within the GIS system. The size of the ditch or tile is based on what is reported on the original ditch maps by the engineering firms. The two variables for Digitized Source are Aerial_Photo and Official. Certain ditches were digitized off the aerial photo and where that was not possible, the ditch maps were scanned and georeferenced so that tiles and certain surface ditches could be scanned. A Y in Official means that there was a ditch map that supported the location of the ditches. A N stated that a map was digitized based on a larger ditch map of the County and the visual location of the ditch. A Y in labeled means that the line has a corresponding label and a N means that the line was digitized but is not necessarily a part of Kandiyohi County's Drainage Ditch System.
