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.

[spatial analysis] The process of examining the locations, attributes, and relationships of features in spatial data through overlay and other analytical techniques in order to address a question or gain useful knowledge.

In statistics, spatial analysis or spatial statistics includes any of the formal techniques which study entities using their topological, geometric, or geographic properties.
This second course usually serves as a pre-requisite for more in depth study of spatial analysis techniques. However "Introduction to Geographical Skills, Techniques, and Applications" is a combination of these two courses. To my knowledge no one in the United States has offered a course like this.

It is difficult to relate wetlands maps to rainfall amounts recorded at different points such as airports, television stations, and high schools.
GIS Spatial Analysis
The primary advantage of GIS modeling is the ability to combine layers of data and investigate interrelationships between them. To provide a simple example, a table containing U.S. Interstate Highways was imported into MapInfo.

With the ArcGIS Spatial Analyst extension in ArcGIS, you can perform ~ on your data. You can provide answers to simple spatial questions such as How steep is it at this location? and What direction is this location facing?
A GIS consists of software, hardware, and personnel for performing ~. Many of the things that wildlife managers do with maps, such as calculate areas, measure distances, and calculate amount of edge, now can be automated with GIS technology.

The idea is that data has to be structured in a certain way to carry out certain types of ~.
The thematic map
By bringing together data from a wide range of different sources, you can visualise trends in the data by creating thematic maps. How does this work?
Viewshed analysis - A method of ~ that aims to determine locations visible from a particular point of observation called the vista point. The end product is a viewshed map depicting all areas that can be seen from one or more vista points.
Land Information Systems (LIS)
Specialized GIS systems most commonly found among municipal agencies geared toward legal, administrative and economic ~. Also known as Land Records Information System (LRIS).
The focus of such systems is the creation of maps: the map is the database. Most desktop mapping systems have more limited data management, ~, and customization capabilities. Desktop mapping systems operate on desktop computers such as PCs, Macintoshes, and smaller UNIX workstations.
Attribute labeling is another issue here. GIS and mapping data requires extensive attribute labeling to link graphical items to database, while CAD drawing are mostly shape and geometry oriented and ~ is hardly done.
This extension will convert USGS DRGs to grids and "clip" away the area outside the map (the collar). The resulting grids can be added to a view as an image and will display in the same colors as the original DRG. This extension requires ~.
