Description:
Abstract:
The Smart Location Database is a consistent nationwide geographic data resource for measuring location efficiency. It includes more than 90 attributes summarizing characteristics such as housing density, diversity of land use, neighborhood design, destination accessibility, distance to transit, employment, and demographics. Most attributes are available for every census block group in the State of Florida. A census block group is a geographical unit used by the US Census that is smaller than a census tract but larger than a census block. Each block groups is a cluster of census blocks having the same first digit of their four-digit identifying numbers within a census tract. Version 2.0 of this data was first released in July 2013. See the user guide for a full description of data sources, data currency, and known limitations: https://edg.epa.gov/data/Public/OP/SLD/SLD_userguide.pdf
Purpose:
The Smart Location Database (SLD) enables the consistent comparison of different locations across the U.S. in terms of their land use characteristics, infrastructure, and accessibility to nearby destinations. SLD attributes were selected for their utility in travel demand modeling studies. However they may also be relevant to land use scenario planning, community development, and public health studies – particularly when obtaining local data is not possible or practical. Planned updates to the SLD will summarize these environment and accessibility characteristics in the form of a Smart Location Index that represents a block group’s relative location efficiency when compared to other block groups within the same metropolitan region.

Sample Variables Included in the Smart Location Database For full descriptions of the variables, see the Smart Location Database User Guide (PDF) (35 pp, 1.22MB, About PDF).

Uses of the Smart Location Database
Accessing and comparing neighborhood conditions Users can browse a simple interactive map Link to EPA's External Link Disclaimer to assess and compare conditions across different neighborhoods in their communities.
Developing indicators of location efficiency EPA is using the Smart Location Database to develop simple indicators of location efficiency. For instance, EPA is working with the U.S. General Services Administration to develop a Smart Location Index that scores census block groups based on their built environment and accessibility characteristics. Block groups that are associated with reduced vehicle miles traveled receive higher scores compared to other block groups within the same metropolitan region. Advanced users could create similar composite indicators to compare walk ability, compact design, or other built environment characteristics. EPA hopes to include additional indicators of location efficiency in forthcoming updates to the Smart Location Database.
Scenario planning and travel demand modeling Planners can use the Smart Location Database as baseline data in scenario planning, sketch planning, and travel demand studies when more detailed or consistent local data are unavailable. Analysts can also use elasticities found in the research literature6 to adjust outputs of travel or activity models that are otherwise insensitive to variation in the built environment.
Conducting nationwide research studies and developing tools Building on previous research, EPA is conducting a nationwide modeling study to predict employee commute travel (e.g., average trip distances, mode share, vehicle miles traveled, etc.) based on workplace neighborhood characteristics. If successful, this study will produce equations for refining travel demand models. This study and others like it also make it possible to create simple online tools to help more communities analyze the potential outcomes of proposed land use development.
Comparing urban form among metropolitan regions Researchers can use the Smart Location Database in nationwide studies that compare metropolitan regions based on urban form characteristics. For instance, analysts could determine the percentage of residents that live in walkable or transit-rich neighborhoods. EPA’s 2012 study Residential Construction Trends in America’s Metropolitan Regions used the Smart Location Database in conjunction with data from the National Land Cover Database and the American Community Survey to measure and compare infill housing development.
Modeling impervious surface growth EPA analyzed variables in a previous version of the Smart Location Database and the National Land Cover Database to create a model and simple spreadsheet tool for estimating new impervious surface growth associated with land use development scenarios. This model is sensitive not only to density of development but also to its relative centrality within the surrounding metropolitan region. For details, see EPA’s Impervious Surface Growth Model.

Resource_Description: DOWNLOADABLE DATA
Distribution_Liability:
The Florida Geographic Data Library is a collection of Geospatial Data compiled by the University of Florida GeoPlan Center with support from the Florida Department of Transportation. GIS data available in FGDL is collected from various state, federal, and other agencies (data sources) who are data stewards, producers, or publishers. The data available in FGDL may not be the most current version of the data offered by the data source. University of Florida GeoPlan Center makes no guarantees about the currentness of the data and suggests that data users check with the data source to see if more recent versions of the data exist.
Furthermore, the GIS data available in the FGDL are provided 'as is'. The University of Florida GeoPlan Center makes no warranties, guaranties or representations as to the truth, accuracy or completeness of the data provided by the data sources. The University of Florida GeoPlan Center makes no representations or warranties about the quality or suitability of the materials, either expressly or implied, including but not limited to any implied warranties of merchantability, fitness for a particular purpose, or non-infringement. The University of Florida GeoPlan Center shall not be liable for any damages suffered as a result of using, modifying, contributing or distributing the materials.
A note about data scale:
Scale is an important factor in data usage. Certain scale datasets are not suitable for some project, analysis, or modeling purposes. Please be sure you are using the best available data.
1:24000 scale datasets are recommended for projects that are at the county level. 1:24000 data should NOT be used for high accuracy base mapping such as property parcel boundaries. 1:100000 scale datasets are recommended for projects that are at the multi-county or regional level. 1:125000 scale datasets are recommended for projects that are at the regional or state level or larger.
Vector datasets with no defined scale or accuracy should be considered suspect. Make sure you are familiar with your data before using it for projects or analysis. Every effort has been made to supply the user with data documentation. For additional information, see the References section and the Data Source Contact section of this documentation. For more information regarding scale and accuracy, see our webpage at: <http://geoplan.ufl.edu/education.html>
