Title: Atlanta Regional Commission MARTA Rail Lines
- Line data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polyline datalayer depicts MARTA rail routes with associated attribute data for the Atlanta Regional Commission's (ARC) 10-county region. ARC documentation states that: This Theme was created in ArcView through 'heads up' digitizing, using MARTA's digital road network as a basemap. For the purpose of this CD, ARC's GIS Division converted the original ArcView shapefile to ARC/INFO format for re-work in ArcEdit. Some of the arcs were adjusted to improve the positional accuracy against the 1993 Digital Orthophoto Quarter Quad (DOQQ) imagery and to coincide with other Themes, primarily MARTA bus routes and rail stations. ARC also used 1999 digital imagery for improved positional accuracy of the new expansion of the North Line to Sandy Springs and North Springs.

Title: Atlanta Regional Commission 1990 Census Tracts
- Polygon data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polygon datalayer depicts 1990 census tract level boundaries with associated census attribute data for the Atlanta Regional Commission's (ARC) 10-county region. Data displayed here was derived from the US Census Bureau 1990 TIGER files. ARC documentation states that: 'Please note, a limited number of 'sliver' tracts were merged with other tracts resulting in a total of 417 census tracts for the Atlanta Region. The Census Bureau published data for 424 tracts including tracts 239.98, 316.97, 316.98, 508.98, 807.97, 807.98 and 912.98. These additional seven tracts resulted from the correction of pre-census mapping errors and fall below the Census Bureau's minimum size standards. Consequently, ARC has incorporated these non-standard tracts into adjacent tracts: 239.98 into 234.05; 316.97 into 313.04; 316.98 into 301.98; 508.98 into 504.06; 807.97 into 801.98; 807.98 into 803.00; and 912.98 into 911.03. Also, due to the fact that the Census Bureau reused the 1980 census tract 303.02 erroneously, ARC instead uses the number 303.08 to correctly refer to this tract and to emphasize that it is a new census tract with no geography in common with 1980 census tract 303.02. In terms of attributes for ARC's 417 census tracts, a number of variables have been extracted from the Census Bureau's Summary Tape Files (STF) for this Theme. In addition, selected demographic data has been included by ARC's Research Division through their annual work on employment and population estimates and forecasts. ARC is the source for all the employment data associated with this theme. The source for population, households, and housing unit data is either the Census Bureau or ARC; source by variable is noted in the variable definitions below. It should be clearly noted that the 2000 population and housing unit estimates appearing in this database file are the result of ARC estimates; they are not 2000 Census counts.

Title: Atlanta Regional Commission Shopping Malls
- Point data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This point datalayer depicts regional shopping malls with associated attribute data for the Atlanta Regional Commission's (ARC) 10-county region. Attributes include: Names of largest (anchors) stores; mall square footage and location by city and street address. ARC documentation states that: This Theme was created from a list of malls in the Atlanta Region originally prepared for the 1997 Regional Development Plan (RDP) to identify major activity centers. The point locations of these malls were digitized in ArcEdit using a variety of data sources, primarily ARC's street centerline database (ARCmap). The locations are approximate centroids of the land area and include some proposed, as well as existing malls.

Title: Atlanta Regional Commission Cobb County Bus Routes
- Line data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polyline datalayer represents the Cobb Community Transit (CCT) Bus Routes. According to the ARC's documentation: 'Shown together in this Theme are the 13 local routes and 2 express routes which make up the CCT system, though none of the route numbers are linked to the geography with this release of the data. Since the last release, Route 30 has been modified and changes to Route 50 and Route 60 take effect April 1, 2002. Route numbers and route beginning and ending points can be obtained from both the system and individual route maps on Cobb DOT's Web site at http://www.cobbdot.org. More detailed route attribute information such as route number, bus stop locations, and bus stop amenities may be added to this CCT Theme in the future.'

Title: Atlanta Regional Commission Bicycle/Pedestrian Trails
- Line data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polyline datalayer depicts bicycle and pedestrian projects, with associated attribute data, for the Atlanta Regional Commission's (ARC) 10-county region. ARC documentation states that: This Theme represents the bicycle/pedestrian component of the 2025 Regional Transportation Plan (RTP) as well as existing bike/ped trails. This dataset was recently revised by Wilbur Smith Associates, working with various staff within the Transportation Planning Division (TPD) and the GIS Division at ARC. This Theme was created in ArcInfo using a variety of hardcopy sources from ARC's local governments for 'heads up' digitizing against the 1999 digital orthophoto quarter quad (DOQQ) imagery. Various features (arcs), representing on-street bike/ped trails and projects, were selected from GDOT's DLGF street centerline file, the primary contributing source to the new Atlanta Region Streets Theme (STREETS). Off-road bike/ped paths were approximated for both existing and proposed (future) trails using this same imagery and street base. To identify the RTP (proposed) trails, use the STATUS field to classify and symbolize, or to query records with a value equal to 'future.' To identify existing trails, use the STATUS field for a value equal to 'existing.' Please note, not all RTP Bike/Ped projects are necessarily represented in this Theme.

Title: Atlanta Regional Commission County Boundaries
- Polygon data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polygon datalayer represents the boundaries of the Atlanta Regional Commission's 10 counties, or those Georgia counties which comprise the greater Atlanta urban and suburban areas. This Theme was derived from the ARC Census Tracts-1990 Layer. Counties included here are Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry and Rockdale. Please note that some Georgia county boundaries have changed from the 1990 to the 2000 Census. As these changes are insignificant in the Atlanta Region, ARC continues to use the 1990 Census geography for our current county boundaries.

Title: Atlanta Regional Commission Area Zip Codes
- Polygon data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polygon datalayer depicts zip code postal zones, with associated attribute data, for the Atlanta Regional Commission's (ARC) 10-county region. ARC documentation states that: This Theme was originally created from the national ZIP Code coverage provided by ESRI and GDT. The boundaries have been significantly changed by ARC's GIS Division using a variety of sources to improve their positional accuracy. Please note, there are some inherent problems with ZIP codes which affect the use of this Theme. Since there are overlapping areas with some of the U.S. Postal Service ZIP code data, this Theme can only show the estimated general area for many ZIP codes. Also note that some ZIP codes refer to post office boxes which only represent point locations, thus are not part of this polygon Theme.

Title: Atlanta Regional Commission 2000 Census Tracts
- Polygon data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polygon datalayer depicts census tract level boundaries with associated census attribute data for the Atlanta Regional Commission's (ARC) 10-county region. Data displayed here was derived from the US Census Bureau SF-1 release of July, 2001. ARC documentation states that: 'This Theme was derived from the 2000 TIGER files provided by the U.S. Census Bureau. All attribute data for the 564 census tracts associated with this 10-county Atlanta Region theme is drawn from the Census Bureau's SF1 release (July, 2001). Please be advised that for the first time, the Census Bureau allowed persons to classify themselves as a member of one or more races in the 2000 census. Users need to note the lack of comparability between race data in the 1990 ARC Census Tracts Theme and race data in this 2000 ARC Census Tracts Theme. Many more data variables are included in the SF1 release than are present here, and please note that the focus is generally on personal and household social characteristics, rather than on economic information (e.g. income and poverty) or housing unit characteristics. These latter variables are what are called 'sample variables' and will be available only in summer 2002 with the release of the SF3 sample. Please note that this Theme currently contains Census demographic data only and does not incooporate details on employment, population estimates and forecasts, or household and housing unit statistics.'

Title: Atlanta Regional Commission MARTA Bus Routes
- Line data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This polyline datalayer depicts MARTA bus routes with associated attribute data for the Atlanta Regional Commission's (ARC) 10-county region. ARC documentation states that: This Theme was created in ArcView using MARTA's digital road network as a base map for 'heads up' digitizing, where bus routes were 'traced' over existing arcs representing the various streets used by MARTA. The street base was originally developed by Navigation Technologies (NavTech) and converted for use within GDS, MARTA's GIS system. For the purpose of this CD, ARC's GIS Division adjusted many of the arcs to coincide with the MARTA rail lines and rail stations, and to improve the positional accuracy against the 1993 Digital Orthophoto Quarter Quad (DOQQ) imagery. This Theme represents the initial release of MARTA's bus route system and does not reflect changes to routes effective March 23, 2002. Although this Theme graphically depicts all of the different routes in MARTA's bus system, there is currently no 'link' to tabular data that would describe these routes maintained by MARTA.

Title: Atlanta Regional Commission TIP Intersections Projects
- Point data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This point datalayer depicts transportation improvement interchanges and intersections with associated attribute data for the Atlanta Regional Commission's (ARC) 10 country region. ARC documentation states that: This Theme currently represents the intersection/interchange component of the FY2002-2004 TIP which is a subset of the 2025 Regional Transportation Plan (RTP). This dataset was originally produced in 1997 by Day Wilburn Associates working with various staff within the Transportation Planning Division (TPD) and the GIS Division at ARC. This Theme was created in ArcView using a variety of hardcopy sources where both existing and proposed intersection and interchange projects were approximated during 'heads up' digitizing, using ARCmap, ARC's street centerline database and other datasets for spatial reference. Please note, not all TIP intersection and interchange projects are necessarily represented in this Theme.

Title: Atlanta Regional Commission Region Boundary
- Polygon data
- 2002
- Not owned by MIT (Owned by Harvard)
Summary: This datalayer consists of a single polygon which depicts the outer boundaries of the Atlanta Regional Commission's 10 counties, or those Georgia counties which comprise the greater Atlanta urban and suburban areas. This layer was developed from a related layer (ARC County layer). Counties included here are Cherokee, Clayton, Cobb, DeKalb, Douglas, Fayette, Fulton, Gwinnett, Henry and Rockdale. The boundary shown here also serves as the ARC Regional Development Center (RDC) boundary under the Georgia Department of Community Affairs (DCA). Please note that some Georgia county boundaries have changed from the 1990 to the 2000 Census. As these changes are relatively insignificant in the Atlanta Region, ARC continues to use the 1990 Census geography for our current county boundaries.
