{ "currentVersion": 11.1, "cimVersion": "3.1.0", "id": 7, "name": "State Senate", "type": "Feature Layer", "description": "This file is a digital geospatial Environmental Systems Research Institute (ESRI) ArcGIS feature dataset that contains polygon feature classes of State Legislative District GIS datasets for Cook County, Illinois. Data is stored as polygon feature classes, and each is saved to an ESRI ArcGIS Version 9.2 geodatabase. The feature dataset contains two feature classes which describe the following features: State Representative District - Lower/House and State Senate District - Upper/Senate. 1) State Representative District (Lower/House) feature class The State Representative District (Lower/House) feature class interprets the location and describes the boundaries of all Representative Districts within Cook County, Illinois. The 59 Representative Districts of Cook County are the areas from which members are elected to state legislatures. The Representative Districts embody the lower (house) chambers of the state legislature. Attribution for this feature class includes a Representative District identifier. This feature class is current as of 2010. 2) State Senate District (Upper/Senate) feature class The State Senate District (Upper/Senate) feature class interprets the location and describes the boundaries of all Senate Districts within Cook County, Illinois. The 31 Senate Districts of Cook County are the areas from which members are elected to state legislatures. The Senate Districts embody the upper (senate) chambers of the state legislature. Attribution for this feature class includes a Senate District identifier. This feature class is current as of 2010. This feature dataset is projected using the Transverse Mercator map projection.
