| Title | Metro Stormwater Geodata Project Sample Pilot Dataset | |||
| Abstract | This dataset is a compilation of geospatial data representing stormwater system infrastructure is a defined pilot area encompassing two stormwater drainage areas ('storm-sheds') within in the cities of Bloomington (Hennepin County) and Eagan (Dakota County). The dataset contains information sourced from numerous agencies and interests including the Cities of Bloomington and Eagan, the Counties of Dakota and Hennepin, the Metropolitan Council, the Minnesota Department of Natural Resources and the Minnesota Department of Transportation.
The point features include representations of basin centroids, best management practice site centroids, hydraulic control structures, inlets, outlets, lift stations and artificial points. The linear features include representation of stormwater pipes, natural and man-made channels and artificial paths. The polygon features include representation of the extends of basins and best management practices sites (swales, rain gardens, etc.) Additional information is made available in the accompanying documentation provided by the Metro Stormwater Geodata Project Steering Team. Links to these documents are found below or can be acquired by contacting the contact person listed in this metadata record. Any questions or comments about suspected anomalies, errors or omissions in this dataset can be addressed to the contact person listed in this metadata record. | |||
| Purpose | To primary purpose of this dataset is to serve as a reference tool for the statewide stakeholder community in Minnesota to enhance their ability to provide comment, suggestions, feedback and recommended improvements | |||

| Section 2 | Data Quality | |||
| Attribute Accuracy | A standard set of attribute fields is included for both the cities of Eagan and Bloomington in the sample pilot dataset, however, not all attributes may be fully available from the original data sources. No attempt has been made by the Metro Stormwater Geodata Project Steering Team to verify the accuracy of the data provided or collected to create the sample pilot dataset. Any questions or comments about suspected errors or omissions in this dataset can be addressed to the contact person listed in this metadata record. Links to that metadata can be found in the Horizontal Positional Accuracy element below. | |||
| Logical Consistency | No attempt was made to ensure topological relationships between the various contributed datasets, nor to edge-match or to rubber-sheet the data together, thus overlaps and gaps may potentially exist between data provided from the different sources. | |||
| Completeness | The dataset is presented 'as is' for the express purpose of facilitating the review of its structure and content and is not offered to meet any specific end-user purpose for flow routing, determination of ownership of fixtures or features or survey-grade accurate measurement or position accuracy of fixtures. Any questions or comments about suspected errors or omissions in this dataset can be addressed to the contact person listed in the individual county metadata. | |||
| Horizontal Positional Accuracy | ||||
| Lineage | The participating cities in the study area assumed the role of converting their data from its native format to the draft Metro Stormwater Geodata Project's Stormwater Geodata Transfer Standard format with UTM coordinates or from paper maps (with the requisite plan drawing references provided for digitizing). These data were then federated by Ramsey County GIS Staff into the final aggregated dataset. | |||
