Tiger 2007 Data Release (ESRI Shapefile)

Tiger 2007 Data Release (ESRI Shapefile)



Finally in a much more 'user friendly' format....
A very quick example of Tiger 2007 in ArcMap - No editing, labels direct from the downloaded files.
Very useable.

"The TIGER/Line Shapefiles are extracts containing selected geographic and cartographic information from the Census Bureau's MAF/TIGER® (Master Address File / Topologically Integrated Geographic Encoding and Referencing) database. The MAF/TIGER database was developed at the Census Bureau to support a variety of geographic programs and operations including functions such as mapping, geocoding, and geographic reference files that are used in decennial and economic censuses and sample survey programs. Spatial data for geographic features such as roads, railroads, rivers, and lakes, as well as legal and statistical geographic areas are included in the product. Other information about these features, such as the name, the type of feature, address ranges, and the geographic relationship to other features, also are inlcuded. The TIGER/Line Shapefiles are made available to the public and are typically used to provide the digital map base for a Geographic Information System or for mapping software.

The 2007 TIGER/Line Shapefiles contain current geographic areas (boundaries of governmental units as of January 1, 2007) and Census 2000 vintage geography. The shapefiles also contain some additional post January 1, 2007 feature updates reported in the Boundary and Annexation Survey (BAS). The 2007 TIGER/Line Shapefiles contain realigned street feature coordinates as a result of the MAF/TIGER Accuracy Improvement Project. The Census Bureau is providing a list of counties that have not been realigned via the MTAIP process."

Metadata Notes
The 2007 TIGER/Line metadata in Extensible Markup Language (XML) format is included with each compressed TIGER/Line Shapefile.

The Spatial Metadata Identifier (SMID) in the All Lines shapefile identifies the source of the coordinates for each line segment and provides the link between the TIGER/Line Shapefile and the source and horizontal spatial accuracy information. Please note that the horizontal spatial accuracy, where reported in the metadata, refers to the realigned street features identified as matched to a positionally accurate source file with that accuracy. Individual feature-based horizontal spatial accuracy does not apply to the entirety of the TIGER/Line Shapefile.

The North American Datum of 1983 was used in the 48 contiguous states, the District of Columbia, Alaska, Hawaii, (only Oahu Island within Honolulu County, HI (15003)), Puerto Rico, the Virgin Islands of the United States, and the Pacific Island Areas. Even though a NAD83 PRJ file will accompany every TIGER/Line Shapefile, there are a few island areas in TIGER that have not gone through the NAD83 transformation process and are still in local astronomic datums. For detailed information regarding these exceptions please refer to the metadata that is included with each TIGER/Line Shapefile.

The Maps API allows you to embed geographical information into your site using JavaScript, you can add overlays to your map including markers, polylines and shadowed information windows. It is a great way to enhance your current site content and best of all, using the Google Maps API is free. To learn more and to find out whether your site meets the terms of use, visit the Maps API FAQ.

Teaser for all that could not make it....
More on the API's and Announcements later today.

Google Maps 2007....

A post for all to post requests on what users would like to see in Google Maps 2007.

continuation from http://googlemapsbook.com/

(Possible) New Features include:

UK Geocoding (even if that means buying Ordnance Survey and Royal Mail!)
Directions but including with Air and Sea (distance/time).
Power Find - not only finds nearest but suggests based on search.
Load from local machine or Google Spreadsheets (fields with lon/lat in)
Gmail Mapping contacts addresses - with quickest route plus via.

Possible New Layers
4 D Time (Temporal) Mapping (example, London over time 4th Century to Present 2007)
Underground mapping?
Sea Bed (bathymetry) mapping layer.
Population density/migration

post a suggestion - your chance to speak to google maps!
(they have been known to read this blog now and then.)
