| Originator | MetroGIS and counties of Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington; positional modifications by LMIC |
| Abstract | This data set is derived from a compilation of parcel layers from the seven Twin Cities metropolitan area counties of Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington. To create the parent data set, parcel data from the seven counties were assembled by Dakota County GIS staff into a common coordinate system and combined into one shapefile; no attempt was made to edgematch or rubbersheet between counties. To create this derived data set for use in EPPLViewer 2001, the data was converted from shapefile format to EPPL .dgt (line) format by LMIC. NO ATTRIBUTE INFORMATION IS INCLUDED IN THIS DERIVED DATA SET. See metadata for each county's parcel data set for more information. |

| Associated Data Sets | Metro wide parcel dataset, in shapefile format, with attributes, is available under the licensing requirements imposed by the counties that supplied the source data. For more information, see http://www.datafinder.org/metadata/metrogis_regional_parcels.htm Parcel data for each of the seven counties is also available individually from each county. Metadata is in the process of being posted at http://www.datafinder.org/catalog.asp |

| Section 2 | Data Quality Information | Top of full metadata | Top of page | |
| Attribute Accuracy | ||||
| Logical Consistency | In the parent dataset, no attempt was made to edgematch or rubbersheet the seven county files; thus overlaps and gaps existed between counties. In creating the EPPL line version, some attempt was made to better match the county data sets together. This process is described under 'Lineage'. However, the file is still not fully edgematched, and some overlaps and gaps occur. | |||

| Lineage | 1. PARENT DATA SET: Creation of metro wide parcel data set from individual counties' parcel data sets. (This pilot MetroGIS parcel data set was assembled by staff at Dakota County Survey and Land Information Department ) Data Transfer and Receipt: - Parcel polygon shapefiles were received from all counties. - Related attributes were received in the form of dBase files or ASCII text files. ArcView Processing: - Shapefiles were projected to UTM Zone 15, NAD 83, meters. - Parcel polygons that did not contain a valid PIN or defined water, rights of way, or common ownership were eliminated. - Parcel polygons were summarized by PIN to combine multiple polygons into single, multi-part polygons. - All attributes except PIN were eliminated at this point and PINs were prefixed with the three digit county FIPS code. - All parcel shapefiles were combined into a single shapefile. - No attempt was made to resolve any mismatches in common lines between county parcel data. Shapefiles store each polygon independently, which allows the original parcel geometry, supplied by the counties, to be preserved. MS Access Processing: - Parcel shapefile dBase component was imported into Access database. - Normalized fields were defined in parcel table. - Individual county attributes were imported into Access database tables. - PIN field was modified to include FIPS code. - Update queries were defined and executed to normalize county data and populate combined parcel table. - Combined table was exported to dBase to replace original dBase component of combined shapefile. 2. DERIVED OR MODIFIED DATA SET: Creation of EPPL7 .dgt version of dataset (linework only - no attribute information) (Land Management Information Center, Minnesota Planning, March, 2001) Metro region wide parcel shapefile was obtained under license from MetroGIS and the producing counties. The metrowide file was split back into individual county datasets. Two county data sets were adjusted to make them align better with adjacent county parcel linework and with the year 2000 1-meter DOQs. This does not constitute a full edgematching or rubber-sheeting of the data sets, but did improve the metch between adjacent counties. After this step the indivdual county parcels were re-appended, then converted to EPPL7 .dgt line files. No attribute information accompanies the file. Processing for these steps was as follows: a. Split metro wide parcel shapefile into individual county shapefiles, using ArcView Query command (query by county code) and saving the results as separate shapefiles. b. Anoka and Hennepin County shapefiles were converted into Arc/Info coverages. These two coverages were then run through Arc/Info TRANSFORM process with a registration tic adjustment. Resultant files were compared with adjacent county parcel data sets and overlayed on orthophoto data. The TRANSFORM process was re-done with different registration tic values until the data sets made a better match with adjacent areas and aerial photos. The Hennepin County mis-registration appeared to result from a misunderstanding of the projection of the original source material. Mis-registration was consistent throughout the file. The Anoka county mis-registration appeared to vary across the file, and the original file was based on coarser source data, so it was not possible to achieve good adjustment. As a result, Anoka County parcel outlines should only be used at coarser scales in the EPPLViewer 2001 program. c. Transformed coverages for Anoka and Hennepin counties were converted back to shapefiles. d. The county shapefiles were then converted to EPPL7 .dgt format. The .dgt is a linework format only and does not carry any attribute data. |
