GIS Analysis Capabilities Much of the initial time and expense in operating a GIS are in developing the various data layers. Once these data layers are in the system, much time is often spent producing maps of the various data layers.

GIS analysis Analysis of GIS datasets based upon common values contained in a database or common location on the earth. This often results in the creation of new GIS datasets containing the results of analyses.

GIS analysis software takes GIS data and overlays or otherwise combines it so that the data can be visually analysed. It can output a detailed map, image or movie used to communicate an idea or concept with respect to a region of interest.

Cluster Analysis- Techniques that group objects (e.g., pixels) into clusters according to user-defined rules. Continuous Data- Quantitative data that varies continuously throughout a raster layer.

Overlay Analysis The integration of different data layers involves a process called overlay. At its simplest, this could be a visual operation, but analytical operations require one or more data layers to be joined physically.

spatial analysis The process of modeling, examining, and interpreting model results. Spatial analysis is the process of extracting or creating new information about a set of geographic features.

International Analysis The IGS currently has seven contributing international analysis centres. From 1994 until 1999, the Geodetic Survey Division was the central processing site for all the data collected at these seven international centres.

To prepare the analysis, cartographers stored digital maps of the water service areas in the GIS. They used the proximity function in the GIS to draw a half-mile buffer zone around the water company service area (fig. 6).

Coastal Change Analysis. For decades, the National Marine Fisheries Service (NMFS) of the National Oceanic and Atmospheric Administration (NOAA) has been concerned about declining fish populations in U.S. coastal waters.
