Geographic Context and Outside Links

To take full advantage of the Contaminated Sediments database, the information provided needs to be looked at in its geographic context. There are many external parameters which affect the concentrations of contaminants such as population in a given coastal area, land use, pollution point sources, and others. Viewing data in geographic context involves using a Geographic Information System (GIS), a system of computer hardware, software, and geographic data designed to support the manipulation, analysis, modeling, and display of spatially referenced data which can, in turn, be used for solving complex planning and management problems. Geographic analysis and mapping allows one to see, explore, and analyze these data by location to reveal hidden patterns, relationships, and trends that canít be seen in spreadsheets or statistical packages.

Spatial and attribute information about features can be stored in two basic data "structures." The vast majority of the data sets use a vector (line) data structure, while other data sets, notably satellite imagery and elevation data, use raster (grid-based) data structures, like a picture on a TV screen. Raster data often represent phenomena that exhibit a gradual transition in character (e.g., rainfall or temperature).

Many collections of geographic data have already been made available on the web, some of which are listed below. Displays (indicated by image of eye) of some of these data are also included. (Disclaimer)
