Northeastern Illinois Planning Commission's 1:24,000 Land Use Inventory for Northeast Illinois. Version 4.0.

Data format: Shapefile

File or table name: LandUse_NIPC_1990v4

Coordinate system: Transverse Mercator

Theme keywords: BULAs (Busted Up Land Areas), land use, wetlands

Abstract: This file is a digital geospatial coverage of the land use, aggregated to 48 categories, for the six counties of northeastern Illinois (Cook, DuPage, Kane, Lake, McHenry and Will). It was created using traditional aerial photo interpretation from non-rectified 1990 aerial photos (flown in 4/90). It is organized in a hierarchic structure, similar to James Anderson's classification system (A Land Use and Land Cover Classification System for Use with Remote Sensor Data, 1976, Geological Survey Professional Paper 964, US GPO, Washington, D.C.). Land use boundaries define homogeneous areas and represent features as they appear on the earth's surface. They are not generalized to any other geography. The minimum resolution of areas outside the City of Chicago is generally 2.5 acres; if a feature is linear, minimum width is generally 200 feet. The minimum resolution of areas within the City of Chicago is generally .25 acres; if a feature is linear, minimum width is generally 100 feet. Exceptions exist where land use polygons broken into two smaller polygons of less than 2.5 acres in area by intersecting roads were preserved. Also tollways, major highways and select rivers were collected uniformly as polygons, regardless of individual width, and all farm houses were depicted as one acre in size, regardless of actual size. Version 2.0 changes: Lake and river names are present on some water bodies in the coverage. Version 3.0 changes: A more rigorous quality control procedure was applied to version 2.0 to check for correct land use categorization. Version 4.0 changes: Errors identified in the course of production of the 2001 Land Use Inventory.

Description:
Abstract:
This file is a digital geospatial coverage of the land use, aggregated to 48 categories, for the six counties of northeastern Illinois (Cook, DuPage, Kane, Lake, McHenry and Will).
It was created using traditional aerial photo interpretation from non-rectified 1990 aerial
photos (flown in 4/90).  It is organized in a hierarchic structure, similar to James
Anderson's classification system (A Land Use and Land Cover Classification System for
Use with Remote Sensor Data, 1976, Geological Survey Professional Paper 964, US GPO, Washington, D.C.).

Land use boundaries define homogeneous areas and represent features as they appear
on the earth's surface.  They are not generalized to any other geography.  The minimum
resolution of areas outside the City of Chicago is generally 2.5 acres; if a feature is linear, minimum width is generally 200 feet.  The minimum resolution of areas within the City of Chicago is generally .25 acres; if a feature is linear, minimum width is generally 100 feet. Exceptions exist where land use polygons broken into two smaller polygons of less than
2.5 acres in area by intersecting roads were preserved.  Also tollways, major highways
and select rivers were collected uniformly as polygons, regardless of individual width, and
all farm houses were depicted as one acre in size, regardless of actual size.

Version 2.0 changes: Lake and river names are present on some water bodies in the coverage.

Version 3.0 changes: A more rigorous quality control procedure was applied to version 2.0 to check for correct land use categorization.

Version 4.0 changes: Errors identified in the course of production of the 2001 Land Use Inventory.

Purpose:
The main objectives for constructing this file were to a) create a land use base consistently developed from a perspective and scale appropriately supportive of NIPC's long range forecast program, and b) create a "seamless" region-wide data layer, giving substance to the evolution of NIPC's geographic information system called ReGIS (Regional Geographic Information System). The file was intended to facilitate general planning at a regional scale; particular emphasis was placed on collecting urban land uses, and some thought was given to additional land uses characterized by drainage perviousness and imperviousness.

Supplemental information:
An extensive list of additional sources were used to determine the location of some land uses and to supplement visual evidence from aerial photos.  The land use polygons were digitized, and are stored in double precision. BULAs (Busted-up Land Areas) represent an attempt by NIPC to establish a network of regional roads and rail features that would allow the fragmentation of aerial photos for land use interpretation.  As a result, most primary and secondary roads from the 1:24,000-scale USGS quadrangle series were captured, in addition to Metra commuter rail and Chicago Transit Authority (CTA) heavy rail lines and stations.  These major roads, Metra commuter rail lines, and CTA heavy rail lines were later extracted from the land use file (therefore they no longer exist in the land use file)and were the basis of three additional files: major roads, Metra commuter rail lines, and CTA heavy rail lines.  These files and their metadata are described elsewhere.

Data Quality Information:


Attribute accuracy:
Attribute accuracy report:
Most landuse code IDs are ascertained to be near 100% complete after repeated visual and electronic inspection and repeated usage.  Since a minimum of field testing was performed, accuracy of codes identifying wetlands, industrial and warehousing and wholesale trade, commercial service trade, and inner city commercial categories will be less than 100%.

Lake and river names were visually checked by NIPC staff several times.  The names have not undergone review by the user community.  In cases where water bodies needed to be split to accommodate two names and there were no resources to delineate the name change, the water body was split at the most logical place.

Logical consistency report:
The landuse polygons, lines and points associated with other features are stored in double precision, using ESRI's ARC/INFO GIS software, as a polygon coverage.  The software provided verification of polygon topology and existence of label points.

As mylars containing landuse codes were completed, they were checked against those adjacent to them to ensure correct edgematching and completeness and correct coding of polygons and lines which crossed onto adjoining mylar sheets.

Completeness report:
All categories of landuse at least 2.5 acres in size outside Chicago and 1/4 acre in Chicago for urban areas that are distinguishable in Spring 1990 aerial photos for Northeastern Illinois, the extent of NIPC's service area, are represented.  Areas beyond NIPC's boundaries were included in some cases.   (Most primary and secondary roads from the paper 1:24,000-scale USGS quadrangle series were captured, in addition to METRA commuter rail and CTA heavy rails and stations.  These geodata are contained in other extracted files.) Completeness is judged to be excellent, based on repeated examination and usage.

Lake and river names are present on select water bodies only.  Not all water bodies have names, including but not limited to detention ponds, farm ponds, and small unnamed ponds and sloughs.

Positional accuracy:
Horizontal positional accuracy:
Horizontal positional accuracy report:
The positional accuracy for landuse categories is based on the use of NIPC's 1990 aerial
photos and 7.5 minute USGS source quadrangles, which are compiled to meet National Map Accuracy Standards (NMAS) for 1:24,000-scale data.  Therefore, accuracy is no better than that of the source material.  Cartographic offsets may be present on the graphic source, due to scale and legibility constraints.  Horizontal positional accuracy for the digital data was tested extensively using paper check plots that were compared to the original aerials, mylar quadrangles, and other source materials.

Process step:
Process description:
NIPC_aerials_1990 were individually overlaid by 12"x12" sheets of mylar, on each of which 4 survey sections were identified.  Section corners and the locations of CTA and METRA rail lines and stations and other BULAs were drafted onto these mylar sheets from a variety of sources, using different colors to differentiate between entity types.  The CTA_maps_1993 and METRA_maps_1993 served as the primary resource for identifying rail alignments and station locations, and the NIPC_aerials_1990, streetfinder_1992 and chicagoland_atlas_1993 were used for verification of those locations.  The BULA_streets_1993, overlaid on the mylar_quads_1990, provided the reference for the marking of BULA lines and selected rivers and major roadways (drawn as polygons) onto the 12x12_mylars_1993.  Areas of land use were identified in several ways, following the classification_plan_1992.  The wetlands_maps_1980 and wet_classification_1979 were used to identify wetland areas, whose current existence was then verified with the NIPC_aerials_1990.  Also used to identify particular land use areas (e.g., schools, forest preserves) were the mylar_quads_1990, streetfinder_1992, chicagoland_atlas_1993, parkland_analysis_1993, Chicago_schools_map_1992, Chicago_schools_docs_1992, cbd_maps_1993, bikeways_map_1979, boulevards_atlas_1989, Cook_atlas_1984, dupage_plat_1983, kane_plat_1992, lake_plat_1992, mchenry_plat_1993, and will_plat_1992.  Each landuse entity was consistently checked against the NIPC_aerials_1990 for verification of its presence.  Finally, staff trained in the interpretation of aerial photographs for the identification of the pertinent land use categories, marked land use area boundaries as a mosaic of polygons on the 12x12_mylars_1993. An additional sheet of mylar was overlaid on and registered to the 12x12_mylars_1993 and marked with the land use identification codes corresponding to the land use polygons.  For the purpose of quality control, as 12x12_mylars_1993 were completed, they were checked against those adjacent to them to ensure correct edgematching and completeness and correct coding of polygons and lines which crossed onto adjoining 12x12_mylars_1993.  This procedure was performed by NIPC staff for Cook, DuPage, Lake and McHenry counties, and by Northern Illinois University (NIU) staff for Kane and Will counties.

Process step:
Process description:
Each of the 12x12_mylars_1993, drafted to represent section corners, rail lines and stations, BULAs, selected rivers and major roadways, and interpreted land use categories, was photocopied and slightly reduced or enlarged to create a copy corresponding in scale to that of the 1:24,000-scale mylar_quads_1990. These photocopies were used to guide the manuscripting of those same entities onto mylar_overlays_1990 at the USGS 7.5 minute base size, a quadrangle at a time. Therefore, several photocopied 12x12_mylars_1993 were used to redraw section corners, rail lines and stations, BULAs, selected rivers and major roadways, and interpreted land use categories on each mylar_overlays_1990, reducing the number of mylar views to be digitized, as well as reducing the amount of edgematching inevitable when working with 973 non-rectified aerial photos.  An additional sheet of mylar was overlaid on and registered to the mylar_overlays_1990 and marked with the land use identification codes corresponding to the land use polygons.  The mylar_overlays_1990 were again checked against aerial resources, mylar_quads_1990 and BULA_streets_1993 before they were considered ready to be registered to an earlier version of tic_file_1994 and digitized.  Additionally, each mylar_overlays_1993 was checked against those adjacent to it to ascertain correct alignment, edgematching, coding and completeness of polygons and lines which crossed onto adjoining mylar_overlays_1990.  This procedure was performed by NIPC staff for Cook, DuPage, Lake and McHenry counties, and by NIPC's contractor, Northern Illinois University (NIU) staff, for Kane and Will counties.  The resulting product was a set of 80 mylar_overlays_1990 registered to their respective USGS 7.5 minute quadrangles.

Process description:
Each of the 80 mylar_overlays_1990 was registered to an earlier version of tic_file_1994.
In the course of registering the mylar_overlays_1990, RMS errors greater than 0.003 were considered unacceptable and re-registered.  The various types of landuse information then were digitized from each of the mylar_overlays_1990 in board inches into individual ARC/INFO coverages.  In order to check their accuracy, check-plots were generated for the resulting digitized_quads_1993, and were compared to the mylar_overlays_1990 from which they were digitized.  Missing or badly placed lines and points were redigitized.  Land use codes were assigned and entered into the file, and the 80 digitized_quads_1993 then were transformed into the Illinois State Plane Coordinate System, feet, NAD 1927.  This work was done by NIPC's contractor, Northern Illinois University staff, from mid-1993 through the first half of 1994.

Process step:
Process description:
Each of the 80 digitized_quads_1993 was digitally edgematched to its adjacent digitized_quads_1993.  Following a regional checkerboard matrix, a consistent set of positionally alternating quads was assigned 'anchor quad' status, and the remaining quads were adjusted to align to the anchor quads.  Each digital line in an adjusted quad which crossed the quad boundary was manually edgematched to the adjacent anchor quad.  Because edgematching had been done during the manuscripting and interpretation steps of the process, the digital edgematching generally resulted in small adjustments. This work was done by NIPC's contractor, Northern Illinois University (NIU) staff, from the end of 1993 through third quarter 1994.  Although edgematched, NIPC's 1990 Landuse Inventory File exists as a set of 80 ARC/INFO coverages, each corresponding to the geographic extent of a USGS 7.5 minute quadrangle.

Process description:
The edgematched_quads_1993  were subjected to an intensive quality control procedure, whereby polygons were checked for mistakes in land use code entry; polygon boundaries were checked for closure; missing polygons were added; discrepancies were eliminated between the lakeshore, as identified on the mylar_quads_1990, versus the NIPC_aerials_1990; and for accurate definition of the City of Chicago boundary. Quality control work was done both at NIPC and by NIPC's contractor, Northern Illinois University (NIU) staff.  Intensive work was done primarily throughout 1994.  This file is considered to be version 1.0 (Oct-Nov 1994).

Process description:
From May 1995 to early 1999, small changes were made to lui_file_1994 resulting in lui_file_1995.  These changes fixed incorrect land use codes where they were brought to NIPC staffs' attention.  Generally, these code changes were accompanied by notations in
corresponding flag fields in the land use data base. No changes to polygon shapes were
made to this file. This file is considered to be version 1.1 (May 1995).

Process description:
In preparation for publishing NIPC's Digital Map of the Region CD-ROM (May 1999), lui_file_1995 was altered to include names of some lakes and rivers.  Names of these water bodies come from a variety of sources including, VLMP_reports, water_quality_reports, DuPage_county_fishing_guide, Cook_county_fishing_guide_1991, Lake_county_lake_guide, NIPC_basemap_1982, CLDMS_199902, and the working knowledge of the region by NIPC staff.  In addition, it was discovered that there were some slight edgematching problems resulting in sliver polygons among several of the 80 quadrangle coverages that comprise lui_file_1995.  These slivers were fixed in lui_file_1999.

This file, lui_file_1999,  is considered to be version 2.0 (May 1999).

Creation of Version 3:  In a separate project, Version 2 of the 1990 land use inventory (lui_file_1999) was used as input to creating the 1995 land use inventory update. As a result of this new project, many miscoded land uses in the 1990 inventory were corrected. Thus, the process of creating the 1995 inventory acted as a quality control step for the 1990 inventory. Quality control was started in November 1999 and was done piecemeal through January 2001.

This file, lui_file3_2001, is considered to be version 3.0 (January 2001).

Continued Quality Control of Version 3: 80 individual land use quad coverages (lui_file3_2001) were mapjoined and saved into  a GIS shapefile (shapefile_lu90qc_2001). This shape file was used to note the following types of errors: 1. Check for illegal land use codes (land_use_categories_1990) 2. Check for land use mis-matches along quad edges. 3. Verification of "non-open space" polygons greater than 480 acres with the land_use_categories values in the 1000 range (urban & built-up) and 4000 range (private, vacant & wetlands). 4. Analysis of variations to spot inconsistencies between 1990 and 1995 land use categorization, e.g. polygons that reverted to open space or polygons still classed as "under construction".

All corrections were posted to a new set of land use quad coverages (lui_file_200104). NO corrections were made to shapefile_lu90qc_2001.

Quality Control for Version 4:  During production of the 2001 Land Use Inventory, all persons involved in interpretation were instructed to compare 2001 land use to what was shown in the 1990 Inventory.  If any inconsistencies appeared that suggested mis-coding in 1990, that polygon was flagged as a potential "1990 Error."  All errors were then checked by reviewing the 1990 aerial photography as well as other resources to determine whether or not the 1990 use was indeed an error.
