Abstract:
This data set contains parcel polygon, tax block polygon, and leasehold polygon features classes, as well as several object classes (tables), for Cook County, Illinois, including a PIN table, a Ref_PIN table, a condo table, and a condo miscellaneous table.

The cadastral data for Cook County have previously not been digital nor automated. This project is the initial automation for this information. This database was designed to represent a continuous, non-overlapping spatial database accounting for all land area in Cook County.

Purpose:
In the cadastral database model, atomic polygons were aggregated to the level of parcel polygons by a unique PIN. This was accomplished by using a master PIN object class (table) that is linked by the key REF_PIN to the parcel feature class. REF_PIN is unique for each parcel polygon shown on the tax map. The PIN table is needed because a single parcel polygon can represent more than one parcel as in the case of condominiums and elevationspecific parcels. The attribute POLYTYPE is a flag that specifies that this condition exists and indicates the need to query additional tables.

In addition to parcels that have only one PIN per polygon, the PIN table accommodates PINs for condominiums, leaseholds, and elevation-specific parcels. The PIN table contains records for each unique 14-digit PIN (the basic 10-digit PIN plus a 4-digit unit number for condominiums and leaseholds). The base 10-digit PIN is included in the table as well as the four components, PINA, PINSA, PINB, and PINP, which comprise the 10-digit PIN.

The Cadastral data set is a depiction of taxable properties in Cook County with selected associated features for enhancement. The purpose of creating this cadastral geodatabase was to update previous data sets and integrate the data with other data sets based on a common geography (digital orthophotoimagery), and serve as a standard cadastral database for virtually all cadastral applications in the County. The creation of this digital cadastral database will allow Cook County to supplant hard-copy tax maps, which are used to illustrate parcel boundaries, with a comprehensive GIS database referenced to an accurate planimetric base map and digital orthoimagery. The County will thus be able to perform maintenance of its land records in the GIS database and automate queries and map output. The Cook County Assessor will not use this database for assessment purposes (such as area of the property). However, the tax map serves the Cook County Clerk to graphically depict legal descriptions of all parcels in Cook County as the tax map represents them.

The primary sources of data for the Cook County cadastral GIS database are the approximately 8,800 tax map "pages" maintained by the Cook County Clerk's Office. All information appearing on existing tax maps as of tax years 2000 or 2001 was incorporated into the cadastral database. The maps are maintained by the Clerk's Office on Mylar and have been published annually.

The County's system of tax maps is based on the Illinois Public Land Survey System (PLSS). In the PLSS, each township is divided into 36 sections, and each section into four quarter-sections. A quarter-section is further divided into two tax map sheets, often called "pages". Each tax map (1/4 mile by 1/2 mile) represents the east or west half of one quarter-section, and typically there are eight tax maps per section. There can be additional pages, known as "flysheets" or "flyleaves", which provide additional information as to subdivisions, condominium/unit, and floor-plans/elevations.

It is not intended that the digital cadastral feature data set should match perfectly with the digital orthoimagery, but rather that it match relatively well so that the digital orthoimagery would provide a visual backdrop to the cadastral information and replicate the tax maps. The tax maps themselves are graphical representations of legal descriptions but cannot be used in place of legal descriptions. As such, this digital cadastral database should not be used in place of legal descriptions, where warranted.

Supplemental_Information:
This cadastral feature data set was originally developed as an ArcInfo coverage. Throughout the metadata, there will be information pertaining to the general data, as well as more specific information referring to the data when obtained and used as an ArcInfo coverage, and an ArcGIS geodatabase. In metadata fields where specific information is required, it will be listed in the same order.

The original data set was created as an ArcInfo coverage and was later converted to an ArcGIS geodatabase. The current data format, as used by the Cook County government, is a geodatabase. The ArcInfo geodatabase model supports topologically integrated feature classes similar to the ArcInfo coverage model but extends the coverage model to support relationship classes, complex networks, and object-oriented features. Geodatabases contain feature classes (which can be organized into feature datasets) and tables. For more information about the use and format of ArcGIS geodatabases, please consult the Environmental Systems Research Institute (ESRI) web page at <http://www.esri.com>.

This data set is one in a series of five cadastral data sets for Cook County, Illinois.

In the cadastral database model, atomic polygons have been aggregated into various layers based on key attributes. Each layer may then be linked to ancillary tables and objects based on its key attribute.

2.0 Georeferencing Tax Maps: SDS georeferenced their project area's Scanned_Tax_Maps to the 1998_Digital_Orthophotos base by aligning common road intersections observed on each. Where Scanned_Tax_Maps did not have a sufficient number of road intersections for georeferencing, SDS technicians visually aligned the Scanned_Tax_Maps to the 1998_Digital_Orthophotos using obvious occupation lines. Thus, real-world coordinates were established as control points for the georeferencing process. This georeferencing step was also performed by Catalyst for the geographical area not covered by SDS. Catalyst then sent their output product to GIS Data (ESRI [Thailand] Co. Ltd.) (GIS Data).

Process_Description:
3.0 Line Work Digitization: SDS and ESRI (Thailand) Co. Ltd. (GIS Data) digitized line work from the Georeferenced_Tax_Maps. GIS Data performed line work digitization using Georeferenced_Tax_Maps from Catalyst. Although SDS and GIS Data used different hardware and software systems to perform these functions, both followed the same procedures with similar methods. Technicians used the Georeferenced_Tax_Maps to "heads-up" digitize and construct line work, creating parcels, blocks, subdivisions, and rights-of-way. All boundary information was placed, such as subdivision, block, and page boundaries.

The "Best Fit" concept was used in the production by SDS. The parcels were digitized using 1998_Digital_Orthophotos and Georeferenced_Tax_Maps as background sources, as the technician used ground evidence to register the property boundaries. Fence lines, hedgerows, building outlines, ditch lines, lakes, and streams, along with the Georeferenced_Tax_Maps were used to determine parcel lines and other boundaries. SDS technicians aligned small blocks of parcels to the ground evidence base (1998_Digital_Orthophotos) and then performed line work digitization. This process thus provided an accurate approach to parcel conversion and isolated parcels requiring rigorous editing. Automatic quality control checks were placed throughout the production flow in order to identify errors or omissions early in the conversion process.

GIS Data performed heads-up digitization of line work directly from the Georeferenced_Tax_Maps. The 1998_Digital_Orthophotos were used for reference to resolve conflicts and make some boundary determinations.

Please refer to the document "GIS Database Development Procedures Manual, Final Version, May 2001", by ESRI, for production rules. This document may be obtained from the Cook County Assessor's Office or from the Cook County Department of Office Technology.

6.0 Quality Assurance/Quality Control: Rigid in-process and postprocess QC measures were implemented throughout the processing to ensure the delivery of quality data. Internal QC processes were performed by the edit staff followed by the contractors' QA/QC management teams. Digital files were required to pass each phase of the QA/QC process with complete accuracy prior to their delivery to Cook County. To supplement on-screen edit processes, hard-copy plots were created to assist editing technicians in reviewing the map data. All plots were checked against the original source documents to ensure accuracy and quality. Automated digital checks were also performed. All parcel line work and annotation were validated by quality audits at several points in the processing.

7.0 Translation into ArcInfo: GIS Data performed their work in the ArcInfo environment; thus, no translation was required. GIS Data created Region Subclasses from the linework polygons for subdivisions, blocks, parcels, lots, and ROW and the associated Regions tables were populated.

For work performed by SDS, the QC_Annotated_Georeferenced_Digitized_Tax_Maps were translated from MicroStation to ArcInfo format. First, SDS used the ArcInfo IGDSARC command to translate the MicroStation file into a Master_Coverage. As objects in the Master_Coverage were coded into distinct ArcInfo objects, they were verified by proprietary macros to be free of dangles and topology errors. Then, those verified objects were removed from the Master_Coverage until all objects were translated. Automated procedures were then utilized to build polygons using the ArcInfo CLEAN command. The resulting polygons were attributed with the original annotation text and the ArcInfo REGIONDISSOLVE command was issued to create regions from the various polygons.

9.0 Final Quality Control of Deliverables: The QC_Tax_Map_Regions was sent from SDS and GIS Data to ESRI Redlands, the primary contractor for this project. ESRI Redlands then sent QC_Tax_Map_Regions to one of two quality control contractors - either Catalyst Consulting, Inc., (Catalyst) or Spatial Data Integrations, Inc., (SDI). ESRI Redlands may have also performed some in-house quality control analysis on QC_Tax_Map_Regions delivered from GIS Data. In any case, the quality control contractors verified the overall quality of the QC_Tax_Map_Regions delivered using ESRI QC View software and ArcView. If the quality was not acceptable, the data set was sent back to the original developing contractor (SDS or GIS Data) for corrections. Any corrected data was then reviewed once again by either Catalyst or SDI or by ESRI Redlands for overall quality until it was acceptable.

 PARCEL
 Description: The feaure class Parcel contains tax parcel polygons,
              which are the basic units used for property tax
              assessment at the County. Each parcel is uniquely
              identified with a Property Index Number (PIN). Where
              multiple parcels occupy the same space on the ground,
              (condominiums), a separate polygon with coincidental
              geometry is represented for each of the parcels so that
              each PIN is represented in the RefPIN table.

 PIN Table
 Description: The object class PIN is a table that stores a variety
              of information about a PIN. It is linked to the PIN
              feature class by the key PIN. The object class PIN is
              used in conjunction with the object classes RefPIN and
              division entry objects to manage the assignment of new
              PINs during the division process. There is one record
              for every active PIN in the PIN table.

 TAX BLOCK POLYGONS (BLOCK)
 Description: The feature class Block is a multipart polygon feature
              class representing the boundaries of tax (parcel)
              blocks. Block polygons are aggregations of parcels that
              share the same block number as part of the PIN. Since
              the blocks do not include any part of a right-of-way
              polygon, block polygons may be discontinuous.
