  7. How does the data set describe geographic features?

    2km_coast_ribbon_sli_2003_over35
    The polygons represent the counties within the United States. The primary legal divisions of most states are termed counties. In Louisiana, these divisions are known as parishes. In Alaska, which has no counties, the equivalent entities are the organized boroughs, city and boroughs, municipalities, and census areas. In the states Maryland, Missouri, Nevada, and Virginia, there are one or more incorporated places that are independent of any county organization and thus constitute primary divisions of their states. These incorporated places are known as independent cities and are treated as equivalent entities for purposes of data presentation. The District of Columbia has no primary divisions, and is considered an equivalent entity for purposes of data presentation. All of the counties in Connecticut and Rhode Island and nine counties in Massachusetts were dissolved as functioning governmental entities; however, the Census Bureau continues to present data for these historical entities in order to provide comparable geographic units at the county level of the geographic hierarchy for these states and represents them as nonfunctioning legal entities in data products. The Census Bureau treats municipios in Puerto Rico as equivalents of counties for purposes of data presentation. (Source: Department of Commerce, Census Bureau)

Why was the data set created?

Annual hydrology product covering band 2km of the coastline for 2003 was exported out of the ENVI software (V.5, 2012) as raster images with all areas dichotomized into water detected (1) and solid ground detected (2) at 250 meter spatial resolution. The raster file was then converted into a vector-based format (ArcGIS shapefile) that permits computations of water and ground areas for each year and to visualize possible change detected between the two spatial means of 2 years of observations (2003 and 2012).


How was the data set created?

  1. From what previous works were the data drawn?

  2. How were the data generated, processed, and modified?

  3. What similar or related data should the user be aware of?


How reliable are the data; what problems remain in the data set?


How can someone get a copy of the data set?

Are there legal restrictions on access or use of the data?
