Description:
Abstract:
Spatial and informational database of irrigation service areas in Division 1 of the South Platte River Basin during the 2005 growing season in support of the South Platte DSS. The republican basin is excluded.
Purpose:
Input for South Platte DSS. Assist Colorado Water Conservation Board in water management and administration.
Supplemental_Information:
Irrigation service areas created using orthophotography, a DEM, and hydrography layers. Verified through correspondence with water commissioners, ditch company personnel, and field visits.

Data_Set_Credit:
SPDSS funded by CWCB and Colorado Division of Water Resources. Input to dataset from various water users including water commissioners, ditch companies, water management groups, and individual farmers.
Native_Data_Set_Environment:
Microsoft Windows XP Version 5.1 (Build 2600) Service Pack 2; ESRI ArcCatalog 9.2.2.1350

Data_Quality_Information:
Logical_Consistency_Report:
General Tests for Data: A quality assurance and quality control procedure was implemented on the dataset. The dataset was checked for consistency with defined procedures and attribute accuracy. QAQC checks were performed at every step of the dataset's creation. This consisted of RTi Staff evaluating the result of each previous step. Progress from each step was checked by different personnel. Positional accuracy of the vector boundaries was also checked.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Horizontal accuracy is believed to be Good. Service area boundaries were digitized from Digital orthophoto quadrangles and a 1:24,000 scale ditch layer.
Quantitative_Horizontal_Positional_Accuracy_Assessment:
Horizontal_Positional_Accuracy_Value: Good
Horizontal_Positional_Accuracy_Explanation: Boundaries were digitized using DOQQs and a 24K ditch layer
Lineage:
Process_Step:
Process_Description:
SPDSS 2001 Irrigation Service Areas were copied to create 2005 service areas.
Process_Step:
Process_Description:
Service Areas were edited (polygons added or removed) according to the irrigation status of the 2005 irrigated parcels.
Process_Step:
Process_Description:
Irrigation service area status was verified in meetings with district Water Commissioners
