Abstract The Metropolitan Area Integrated Land Use/Cover file serves as a navigation and reference tool for the LMIC Environmental Atlas and AtlasGDS desktop GIS products. It combines the 1997 Generalized Land Use data set produced by the Metropolitan Council with additional land cover classifications. The 1997 Generalized Land Use data set areas defined as 'vacant/agricutural' or 'parks and recreation areas' were integrated with natural resource features such as wetlands and forest cover from other data sets. Some ownership information was also added. The data set is in EPPL7 raster format, with a 30-meter grid cell size.

The original 1997 Generalized Land Use data set encompasses the seven county Twin Cities (Minneapolis and St. Paul) Metropolitan Area in Minnesota. The data set was developed by the Metropolitan Council, a regional governmental organization that deals, in part, with regional issues and long range planning for the Twin Cities area. The data were interpreted from 1997 air photos and include the generalized land use classes of: single family residential, multi-family residential, commercial, industrial, public and semi-public, airports, parks and recreation, vacant and agricultural, major four lane highways, open water bodies, farmsteads, extractive, public industrial, industrial parks not developed, and public and semi-public not developed.

Title Integrated Land Use/Land Cover 1997 - Metro Area
Abstract The Metropolitan Area Integrated Land Use/Cover file serves as a navigation and reference tool for the LMIC Environmental Atlas and AtlasGDS desktop GIS products. It combines the 1997 Generalized Land Use data set produced by the Metropolitan Council with additional land cover classifications. The 1997 Generalized Land Use data set areas defined as 'vacant/agricutural' or 'parks and recreation areas' were integrated with natural resource features such as wetlands and forest cover from other data sets. Some ownership information was also added. The data set is in EPPL7 raster format, with a 30-meter grid cell size.

The original 1997 Generalized Land Use data set encompasses the seven county Twin Cities (Minneapolis and St. Paul) Metropolitan Area in Minnesota. The data set was developed by the Metropolitan Council, a regional governmental organization that deals, in part, with regional issues and long range planning for the Twin Cities area. The data were interpreted from 1997 air photos and include the generalized land use classes of: single family residential, multi-family residential, commercial, industrial, public and semi-public, airports, parks and recreation, vacant and agricultural, major four lane highways, open water bodies, farmsteads, extractive, public industrial, industrial parks not developed, and public and semi-public not developed.
Purpose Originally created as a reference tool to be used with the EPPLViewer 2001 software, to expand the Metropolitan Council land use map for use in portraying natural systems, and as an exploration/navigation/reference tool for EPPLViewer 2001. It has since been incorporated into the LMIC Environmental Atlas and AtlasGDS desktop GIS products.

Section 2 Data Quality Information Top of full metadata Top of page
Attribute Accuracy Attribute Accuracy information is provided from the metadata for the parent Metropolitan Council 1997 Land Use Data Set:

During the land use interpretation, digital orthophotos and county parcel data with assessor's land use/type attributes were used. Reverse directories and field checks were used to augment this interpretation. Also, comments and corrections for the 1997 data from the cities and townships (each of which was given a map with the preliminary 1997 data) were used to update the 1997 layer.

Known deficiencies in the data set include:

- The only delineated roads are those with at lease 4 lanes, controlled access and a 200 ft. right-of-way, and all 4-lane roads with a Metropolitan Council functional class designation of 'Principal Arterial.' All other roads are incorporated into the adjacent land use category.
- The only delineated railroads are those with at least 2 tracks side-by-side and they are classified as 'Industrial'. All single track railroads are incorporated into the adjacent land use category. However, in some instances, a single track railroad may have been classified as vacant.
- The interpretation of the 'Public & Semi-Public' and 'Parks & Recreation' classes can be fuzzy. For example, ball fields adjacent to a school are classed as Public in this data set, while ball fields in other areas are classified as 'Recreation' if they are not owned by a school district.
- Horticultural specialty land uses (the growing of nursery stock, flowers, seeds, sod, and food crops gown indoors) are included in the 'Industrial' category where they could be delineated (e.g. large greenhouses). However, most of these facilities that are out of doors are included in the 'Agricultural and Vacant Lands' class.
Logical Consistency
Completeness Entire seven county geographic area is covered. Incompleteness in attribute information is discussed under 'Attribute Accuracy' above.
Horizontal Positional Accuracy Horizontal Positional Accuracy information is taken from the metadata for the parent Metropolitan Council 1997 land use data set:

Estimating the horizontal positional accuracy of this layer is somewhat complicated, because a number of factors must be considered. For this reason, a description of some of these factors seems instructive.

Many of the boundaries defining land uses in urban areas were drawn along parcel lines based on parcel data from the metro counties. Metro county parcel data sets vary greatly in positional accuracy as well as in the documentation of that accuracy. Furthermore, positional accuracy may vary for different features within the same parcel data set. An additional factor is the degree to which Metropolitan Council staff matched the parcel boundaries in heads up digitizing within ArcView. The scale at which lines were digitized varied as staff zoomed in and out while heads-up digitizing within ArcView, however most lines were digitized at an on-screed scale of no higher than 1:3000. In highly urbanized areas, 1:1500 was more common.

In rural areas, parcel boundaries were often not used. Rural residential land use boundaries were defined by the mowed lawns or used areas around the dwellings as viewed on the Metropolitan Council 1997 digital orthophotos. For this reason a positional accuracy estimate would have to describe the accuracy with which the interpreted boundary of this area was defined as well as whether the interpretation of the boundary was correct or inaccurate (causing a positional error).

Boundaries of water features were based on the digital orthophotos taken in April of 1997 at the height of a major flood on the three major metro rivers. Therefore the water boundaries for the rivers were taken from the 1990 land use in many cases. Lake boundaries were taken from the orthophotos. We do not have an estimate as to what degree the wet spring influenced any of the lake levels in the metro area.


A variety of other factors play a role in the positional accuracy of this layer. The information in the Entity and Attribute Detailed Citation (Section 5 of the metadata) may shed light on some positional issues with respect to this data set.

As a general rule when developing this data set it was the Metropolitan Council's intention to meet the National Mapping Accuracy Standards at 1:24,000 (within approximately 40 feet of actual location). No testing has been conducted to verify this.

Additional information from LMIC: vector data was generalized by gridding at a 30-meter cell size level.
Lineage 1. PARENT DATA SET: Creation of original Metropolitan Council 1997 Land use Data Set -

DATA SOURCES:
- 1997 digital orthophoto quarter quads (0.6 meter resolution)
- 1990 land use delineations (1:24,000).
- The Lawrence Group's road centerline layer (1:24,000).
- parcel data from all seven counties
- reverse directories and field checks
- community feedback from preliminary maps sent out to them

HISTORY OF THE LAND USE DATA:
The Metropolitan Council has conducted analyses of land use for the years 1966, '70, '74/'75, '78, '80, '84, '90 and '97. Each project included analysis of aerial photography as well as field checks and the use of other sources to delineate land use and land use change.

Land use maps were developed from these data for the years 1966, '75, '84, '90 and '97. In addition, reports on land use change were prepared for the periods of 1960-1975, 1970-1978, 1970-1980, 1980-1990, and 1990-1997.

PROCESSING STEPS FOR THE 1997 LAND USE LAYER:
The 1997 land use layer was developed on the base of the 1990 land use data set. The primary tools used for the 1997 land use interpretation were the 1997 digital orthophotos and county parcel data with assessors attributes indicating various land use type information.

It is important to note that the assessors attributes varied greatly from county to county. In many cases the land type or use categories used by the county for assessment purposes did not match the categories used in this data set. The assessors attributes were matched as closely as possible to Council land use categories. Additionally the property owner name from the parcel data and entries in reverse directories were also used as aides in the land use interpretation. Where these sources were insufficient to determine the land use category, field checks were performed.

Once the preliminary 1997 land use data set was completed, each of the approximately 200 cities and townships within the metro area was sent a map of the preliminary data and asked to provide comments and corrections. 85% of the those cities and townships responded and their comments were used to enhance the accuracy of the 1997 land use data.

The original categories used for land use breakdowns were established in 1962 and have been modified only slightly over the years of generating the Twin Cities generalized land use maps (1966, 1975, 1984, 1990, and 1997).

The interpretation was conducted on 3.25 minute quadrangles (USGS quarter quads). The editing was done using ArcView 3.1 software. Once completed, the shape files were converted to polygon ArcInfo coverages and then the tiles were combined into one metro wide layer, where small sliver polygons were removed and other miscellaneous editing was done. The 1997 land use layer was then dissolved out of the 1984-90-97 combined layer.

2. DERIVED DATA SET (LMIC Data Conversion): conversion to a raster data set and addition of natural resource feature information to the data set:

a. Metropolitan Council 1997 land use data shapefile was converted to an EPPL .dgt file, then gridded with a 30-meter cell size to create an EPPL7 raster data set.

b. Where the Metropolitan Council land use category was 'agricultural/vacant' or 'parks and recreation', several changes were made to the file. The EPPL7 EVAL and 2-WAY RECLASS commands were used to make the following changes:

b1. National Wetlands Inventory wetlands (except for deepwater habitat classification) 30-meter data was extracted from Minnesota.Data Volume 2.

b2. Lakes and shallow wetland water habitats were pulled from the DNR-enhanced 24K lakes layer. This data had been obtained from the DNR data deli by USGS 7.5-minute quadrangle tile, appended together into a metro-wide file using the Arc/Info APPEND command, converted to a metro-wide shapefile, then converted into an EPPL7 .dgt file and gridded with a 30-meter cell size to produce and EPPL7 data set.

b3. Forest cover information was added from the 1991 DNR Phase II forest inventory for the metro area. This information was already available in 30-meter EPPL7 format from the EPIC Metro30 database.

The EPPL7 EVAL amd 2-WAY RECLASS commands were used such that, if the original metro land use 1997 category for a cell was 'vacant/agricultural' or 'parks and recreation', the cell value would be replaced by values from one of the above data sets, if there was a relevant value.

Entity and Attribute Detailed Citation The original categories used for the Metropolitan Council land use breakdowns were established in 1962 and have been modified only slightly over the years of generating the Twin Cities generalized land use maps (1966, 1975, 1984, 1990, and 1997). Categories 16, 19, and 20 were added by LMIC to create the Integrated 1997 Land Use Layer. Detailed category descriptions for this layer are as follows:

1 - Single Family Residential
Includes all individual, free standing single family housing (including manufactured housing). Within the MUSA (metropolitan urban service area) and in residential developments outside the MUSA, the lot lines visible on the photos were used for determining residential land use boundaries. Where residential developments were visibly not complete, the undeveloped area was classified as vacant. For the scattered, rural residential areas outside the MUSA, only the portion of lots used for residences was assigned to the residential category.

2 - Multi-Family Residential
Includes all multiple dwelling units such as duplexes, bungalows, twin homes, townhouses, quad homes and apartment complexes. Also, buildings that are primarily apartments that have some group dining facilities are included (however, not those buildings that fit the census definition of 'Group Quarters', such as, dormitories, nursing homes or medical care facilities).

3 - Commercial
Includes all retail sales, services, hotels and motels, health care facilities (e.g. medical and dental clinics and offices and medical laboratories, but not hospitals and nursing homes) and recreational services that are predominantly privately owned and operated for profit (e.g. theaters, bowling alleys, equestrian ranches) except golf courses. Hospitals and nursing homes are included in the 'Public & Semi-Public' category and golf courses are in the 'Parks & Recreation Areas' class. For large shopping centers, only actual developed areas are shown. This is done so that over the years new development can be shown (e.g. restaurants or gas stations on perimeter roads).

4 - Industrial
Includes the Federal Standard Industrial Classification (SIC) codes 14 through 50. This includes manufacturing, transportation, construction, communications, utilities, and wholesale trade. Also included in the 'Industrial' category are some horticultural specialty land uses (e.g. large greenhouses that do not sell to the public). As of 1997, gravel pits and quarrying have been placed in a new category called 'Extractive' and all publicly owned areas that are predominantly of industrial nature have been placed in a new category called 'Public Industrial.'

5 - Public Semi-Public
Includes the land under and adjacent to schools (public and private), hospitals, churches, cemeteries, ice arenas and all facilities of local, state and federal governments, including convalescent homes, mental institutions and penal facilities maintained by any level of government. All lands within the boundaries of these institutions and facilities are included in this category. However, in certain instances unused lands were included in the 'Public & Semi-Public Vacant' category (e.g. the University of Minnesota's property in Rosemount, or part of the land adjacent to the Minnesota Veterans Home in Hastings).

6 - Transportation
This category combines the Metropolitan Council land use categories of 'airports' and 'major four-lane highways'. The 'airports' category includes airports of all types. The 'major four-lane highways' category includes only the major interstate freeways and 4 lane divided highways with rights-of-way of 200 feet or greater.

7 - Parks & Recreation Areas
Includes all parks (city, regional and state), wildlife refuges, playgrounds, zoos, gun clubs, golf courses and similar areas (this includes DNR wildlife management areas and scientific and natural areas). Parks are delineated using their actual boundaries taken directly off comprehensive plans, park maps or county parcel data. Wetlands, forest cover and open water overwrote this data category.

8 - Vacant/Agricultural
In the Metropolitan Council 1997 land use data set, this includes land identifiable from aerial photos as open and in agriculture uses, other uses where no buildings are present or unused land. Please note that indoor horticultural specialty land uses (the growing of nursery stock, flowers, seeds, sod and food crops in large greenhouses that do not sell to the public; and large concentrations of agricultural buildings (e.g., barns, sheds and silos)) are included in the 'Industrial' category where they can be delineated. Where residential uses are on larger lots, the residential land use category my include only the house and mowed portion of the parcel, with the rest being placed in this Vacant and Agricultural category. In the updated data set, areas that were originally defined in this category but which were indicated by other datasets to be wetland, lake, or forested, were replaced by those natural resource categories. Wetlands, forest cover and DNR open water overwrote this data category.

10 - Open Water Bodies
In the original Metropolitan Council 1997 land use data set, this included lakes larger than 5 acres and rivers wider than 200 feet. Additional lake features from the DNR-enhanced 1:24,000 lakes data set were added into this category in the updated version. The following Metropolitan 1997 land use data categories were overwritten by DNR open water data: parks; vacant/agriculture; industrial parks, not developed; Met Council Open Water, 1997; public and semi-public lands.

11 - Farmsteads
Includes only that portion of land that encompasses the buildings on the farmstead.

12 - Extractive
Includes all gravel pits and quarries.

13 - Industrial Parks not Developed
Parcels of land in a designated (named) industrial park but not developed. NWI wetlands, forest cover and DNR open water classifications overwrote this data category.

14 - Public & Semi-Public Vacant
A government or university owned parcel of land that is undeveloped (e.g. part of arsenal site in Arden Hills or the University property in Rosemount). NWI wetlands, forest cover, and DNR open water classifications overwrote this data category.

15 - Public Industrial
Includes all publicly owned areas that are predominantly of an industrial nature (e.g. waste water treatment plants, city bus garages, and Dept. of Transportation sand and salt stockpiling areas). In the past, some of these have been coded as industrial and others as public.

16 - Wetlands (Emergent-Forested Habitats)
Includes wetlands classified as Emergent-Forested Habitats in the National Wetlands Inventory. The following Metropolitan 1997 land use data categories were overwritten by NWI wetland data: parks; vacant/agriculture; industrial parks, not developed; public and semi-public lands.

19 - Wetlands (Shallow Water Habitats)
Includes wetlands classified as 'shallow water habitats' in the DNR-enhanced 1:24,000 lakes data set. The following Metropolitan 1997 land use data categories were overwritten by DNR shallow water habitat data: parks; vacant/agriculture; industrial parks, not developed.

20 - Forested
Includes areas categorized as 'forested' in the DNR Phase II Forest Inventory (1991). The following Metropolitan 1997 land use data categories were overwritten by DNR forested data:: parks; vacant/agriculture; industrial parks, not developed; public and semi-public lands.
