Metropolitan Council and The Lawrence Group (TLG)The Lawrence Group, under contract with Metropolitan Council, created a 1990 Census Bureau block polygon dataset for the Twin Cities Metropolitan Area (Anoka, Carver, Dakota, Hennepin, Ramsey, Scott and Washington Counties). This dataset is coincident with and developed using the TLG Street Centerline and Landmarks databases where 1990 block boundaries fall on those features. For those block boundaries that are defined by features not included in TLG databases, TLG used other digital resources to generate these boundaries, such as orthophotography or additional features from city and county GIS databases. TLG used it's best judgement to digitize block boundaries when the block boundaries followed nonvisible features or street extensions. This is a MetroGIS Regionally Endorsed dataset.The dataset was developed to have a 1990 census block database that is aligned to the TLG street centerlines and landmarks files, for use in analysis which utilizes both the census data and TLG street centerlines/landmarks. Blockgroup and tract datasets have been desolved from the block dataset. Additionally, since TLG's street centerline dataset is aligned within county rights-of-way for these counties, this dataset allows for parcel based analysis as it may pertain to census blocks, block groups and tracts. This dataset is a precursor to creating a 2000 census block dataset when the 2000 TIGER/Line files are released by the Census Bureau.1990 Census.
