Whiskbroom scanning uses a scanning mirror that quickly sweeps back and forth over an area while taking an image. These are whiskbroom and pushbroom scanning. There are two main types of scanning systems that obtain the various types of imagery used in GIS today (Verbyla, 1995). Images gathered via satellite are some of the most commonly used images in GIS. Multispectral imagery is imagery that is made up of two or more images that are taken at the same type but in different portions of the electromagnetic spectrum.

It is mostly used for agriculture, forestry management and other projects that examine the Earth’s physical landscape. Hyperspectral imagery is imagery that is used for classifying different land types on the Earth (Dempsey, 2011). Hyperspectral, multispectral and panchromatic are general terms that describe imagery types. Imagery that is used in GIS can include aerial photos, satellite images, thermal images, digital elevation models (DEMs), scanned maps, land classification maps and surfaces created from a previous analysis that are saved as an image ( Managing Imagery with ArcGIS 10). This makes it versatile for a wide variety of different GIS projects and as such it is a common type of data for GIS projects. It comes in many different types and it is able to show both large and small areas in varying levels of detail. Imagery is a data type that is extremely useful for GIS. When all of the pixels are combined an image is formed. The different values assigned to the pixels typically represent quantities that identify things like elevation, slope gradient, or spectral brightness of an area (Verbyla, 1995).

Each grid is called a pixel and the pixels are assigned different numeric values. As such, all GIS images are made up of a grid of numbers that are arranged into rows and columns. In terms of the specific GIS data type, imagery is considered raster data. In addition, printed topographic maps that are scanned as digital images also constitute imagery. These can be photos that are printed on film or they can be taken with a digital camera and stored as digital images (NCSU Libraries). Normally photographs used for GIS projects consist of images gathered from a satellite or an aircraft.

The use of this protocol can provide results relevant to both classroom learning and cognitive science principles.Imagery is a type of data that is useful for many GIS applications and is defined as any type of photograph. The protocol also offers options to modify the procedure to a more traditional DRM paradigm without imagery and/or list type manipulations. The automated nature of the list presentation provides the ability to systematically vary variables of interest, and the paper and pencil method of data collection affords an easily accessible method for collecting data in classroom settings. The protocol detailed here describes a four-step procedure - list presentation, immediate recall, distractor phase, and final recognition - that can assess the effects of list type and imagery instruction within the DRM paradigm on memory.

Often, participants immediately recalled and later recognized words that were related to the list items but were not actually presented these are known as critical lures and indicate a false memory. Participants used paper-pencil recall packets to immediately recall list items, complete a distractor activity, and take a subsequent final recognition test. The automated presentation presented word lists to participants, one word at a time, alternating between phonologically and semantically related lists. We then recruited undergraduate classes and instructed some of the classes to create mental images of the list words as they were being presented, while instructing the other classes to simply remember the words. We adapted word lists from previous DRM studies to suit imagery procedures and created an automated presentation to present the word lists in classroom settings. To do this, we used a modified version of the Deese Roediger McDermott (DRM) paradigm. The purpose of the method presented here was to induce false memories using lists of either semantically or phonologically related words and to assess the effects of imagery instructions on the recall and recognition of those false memories. Associated word list procedures can elicit false memories in predictable ways by inducing associative processing, thus making it harder to monitor the accuracy of memories.
