Check Topology: Correct overlapping polygon topology errors
*note: slightly overlapping polygons and gaps may still exist, typically along pivot edges and/or roads
1) No Overlaps
2) No Gaps (*of significant size)

"Irrigated Lands" data was created from the best available data for each year.
"Irrigated Lands" data as provided by IDWR does not represent an on-the-ground survey nor is it based on a thorough water right review.
Irrigation status in the "Irrigated Lands" data is not determined using spectral signatures but is based on a GIS analyst's manual interpretation of remotely sensed imagery.
Field boundaries depicted within this dataset are not to be used for legal purposes.
The constantly expanding scope, completeness, and complexity of GIS technologies, including image processing and interpretation, allows IDWR to constantly improve upon the methodology used to create "Irrigated Lands" data. If you are interested in the evolution of the “Irrigated Lands” project, please contact IDWR’s GISInfo to obtain the Editing Methodology and Guidelines documentation.
This dataset is generated in support of determining the status and trends of aquifer levels in the Malad Valley Groundwater Management area (GWMA) located primarily in Oneida County, Idaho.
This layer depicts polygons representing land within the Malad Valley classified as either "irrigated", "non-irrigated" or "semi-irrigated", where the semi-irrigated classification typically depicts residential land or areas where irrigated and non-irrigated areas co-mingle.
The original line work used to create this dataset is the vector geometry used for the 2019 Bear River Compact Depletion study. Field boundaries are refined using primarily 2017 National Agriculture Imagery Program (NAIP) imagery, but Digital Ortho Photo Quadrangle (DOQQ) imagery, or other high resolution imagery are used as needed.
Attribute assignments for irrigation status (irrigated, non-irrigated, and semi-irrigated) are determined using available 2017 Sentinel imagery as background reference as well as 2017 NAIP imagery. The interpretation and classification process for delineating irrigated land is described in detail in the report "2006 Irrigated Land Classification for the Eastern Snake Plain Aquifer" archived on the IDWR website: Legal Actions > Delivery Call Actions > SWC > Archived Matters > Technical Working Group Documents (https://idwr.idaho.gov/legal-actions/delivery-call-actions/SWC/archived-matters.html#twg-documents)

Positional Accuracy requirements are determined by its use in formulating a water budget which accepts "less-than-perfectly accurate" horizontal accuracy. However, given any time constraints, efforts are made to refine positional accuracy based on NAIP and DOQQ imagery.
Visual inspection against imagery and IDWR's water rights database.
Attribute assignments for irrigation status (irrigated, non-irrigated, and semi-irrigated) are determined using available Sentinel2 satellite imagery as background reference. Sentinel2 imagery is 10-meter resolution. National Agriculture Inventory Program (NAIP) imagery, Digital Ortho Photo Quadrangle (DOQQ) imagery, and other in-house, scanned aerial imagery is used for determining irrigation status and refining linework geometry. Hence, attribute accuracy is determined by the scale of those sources.
Visual inspection against imagery and IDWR's water rights database. A topology check was performed to repair overlapping polygons and data gaps of consequential size. Overlapping polygons and data gaps of consequential size were minimized to the best of the analyst’s ability under existing time constraints.
The data layer consists of polygon features attributed by GIS analysts based on visual interpretation of remote sensing and aerial imagery as well as supplemental information provided in the water rights database.

Concentrated animal feeding operations are classified as semi-irrigated in the 2011 and later Irrigated Lands Data layers.
