Title: DNR Hydrography Dataset

Abstract: The DNR Hydrography Dataset is the centralized SDE data storage for master versions of DNR hydrographic spatial features (effective 2012). It includes the authoritative versions of the following statewide feature classes:

The DNR Hydrography Dataset is a collection of the "best available" DNR spatial features representing MN surficial hydrology. These features originate from multiple sources representing a range of scales and accuracies. All feature classes are (will eventually be) topologically related and will function as an integrated set of statewide features. Most DNR hydro-related layers are (will eventually be) derived from this central data storage so that master features may be edited once and then remain synchronized among all derived layers.

NOTE: This dataset will be replaced by the new National Wetlands Inventory update (2009-2014) upon it's completion in 2020. The NWI is the newest source of statewide hydrographic features based on modern imagery. DNR Hydrography attributes will be conflated over to the new NWI dataset to accommodate DNR business needs.

NOTE: The DNR Hydrography dataset replaces the older DNR 24K and DNR 100K data layers, including those derived layers listed below. Users should discontinue use of these older layers.

100K: dnr_100k_hydro_area_features, dnr_100k_hydro_stream_centerlines, lake_dnrpy2, wetl_dnrpy2, strm_usgsln2
24K: dnr_24k_lakes_and_open_water, dnr_24k_rivers_and_streams, dnr_24k_perennial_stream, lake_openwpy3, strm_baseln3, strm_pwiln3



Purpose: To provide a comprehensive, statewide hydrography layer which serves as the base GIS layer for all DNR business needs, including mapping, analysis, reporting, statuatory responsibilities, etc. Examples of uses are regional hydrographic modeling/analysis, basemapping, limnological studies, and linkage to Fisheries data.

Section 2: Data Quality

Attribute Accuracy:

Logical Consistency:

Completeness: Data exist statewide.

Horizontal Positional Accuracy: Horizontal positional accuracy is based on accuracy of the native datasets. Some features have been re-delineated by on-screen digitizing using DOQs and FSA imagery at scales of ~ 1:2000 - 1:5000.

Vertical Positional Accuracy: N/A

Lineage: See LINEAGE of individual feature classes.

Source Scale: Source layer wetl_dnrpy2: 100000
