Use Constraints: The development of the coverages in the NRGIS Library represents a major investment of staff time and effort. As a professional responsibility, the the Iowa DNR expects to receive proper credit when these GIS coverages are utilized. The Department also expects that the original documentation will remain with any redistribution of these coverages.

Data Quality Information:
Positional Accuracy:
Horizontal Positional Accuracy:
Horizontal Positional Accuracy Report: Precision of data points varies from five quarter sections to section centers. Locations of older wells were generated by in house routines in the past, whereas newer points have been assigned utm (Nad83) and Latitude/Longitude values via GPS or in house programming routines and Esri ArcMap.

Process Step:
Process Description: This dataset has been filtered to only sites that have xy coordinates and elevation within the GEOSAM dataset (SQL), from which an Event theme is generated and then exported to a point shapefile (Nad83 utm coordinate projection; Zone 15). Information contained within this dataset includes x & y coordinates (both in Nad83 utm and Latitude/Longitude), owner name at time of data entry, total depth of well or height of measured section, elevation of site where it can be determined from a variety of sources (e.g. 7.5' quadrangle), or utilizing the Surface Spot tool in ArcGis and interception of the 10 meter gridded elevation surface from the Dnr NrGisLib coverages; and numerous other site specific information. The Geologic_Sampling_Points dataset is in a constant state of update as sites are being field located/re-evaulated and then corrected in the Geosam database.
