Below is the uncorrected machine-read text of this chapter, intended to provide our own search engines and external engines with highly rich, chapter-representative searchable text of each book. Because it is UNCORRECTED material, please consider the following text as a useful but insufficient proxy for the authoritative book pages.

A-1 One of the most useful sources of contemporary aerial pho- tography and topographic maps is the Microsoft TerraServer Web site (http://terraserver.homeadvisor.msn.com/). Figure A.1 shows the homepage of the TerraServer Web site. Infor- mation about navigating the Web site is available under the “About” tab, but the basic steps to downloading imagery from this site are provided here. There are several ways of locating imagery at the Terra- Server Web site. The primary method is to type the name of a town or geographic feature near the area of interest in the box labeled “Search TerraServer” shown in Figure A.1. One can also left-click the mouse pointer on a spot on one of the green areas of the world map. If the geographic coordi- nates of a specific site are known, the user can left-click on the “Advanced Find” tab, which will send the user to the “Advanced Find” page shown in Figure A.2a. The user can search for a specific address, place, or stream gauge, or the user can search using geographic coordinates, as shown in Figure A.2b. When the user types in the name of the place of interest, a page may appear that has multiple listings with the same name from which the user can choose (see Figure A.3). This “Find Results” page lists available aerial photography and topographic maps for the various sites with the same place name. Once the user has chosen a particular location, left- clicking the mouse button on the image of choice brings up the image page. Figure A.4 shows the image page with a portion of a topographic map for an area near Judson, Min- nesota, and Figure A.5 shows the page with an aerial photo- graph for the same area. The toolbar at the top of the map or photo image page contains several tabs that allow the user to adjust the size of the image viewed, to zoom the image, to view the scale and coordinate details of the image, and to download the image. A zoom bar allows the user to zoom the image, and the arrows around the image are used to move the image laterally. The types of topographic map images shown are depen- dent on the resolution chosen. For example, map images with resolutions of 4 m or greater are from 7.5-minute series topo- graphic quadrangle maps (scale 1:24,000). Map images with resolutions between 16 m and 4 m are 15-minute topographic quadrangle maps (scale 1:62,500), and images with map res- olutions less than 16 m are 1 degree × 2 degree topographic maps (scale 1:250,000). TerraServer images of aerial pho- tographs are also based on the image resolution chosen. Each image of a map or aerial photograph has a resolution based on the number of pixels that make up the image. For example, the images shown in Figures A.4 and A.5 have res- olutions of 16 m, meaning that each image pixel covers 16 m. To determine the number of pixels in each image, as well as the coordinates of the image, the user selects the “Info” tab at the top of screen as shown in Figures A.4 and A.5. The “Image Info” page (see Figure A.6) provides the image size in pixels, the size of each pixel, the coordinates of the image, the date the image was photographed, and the Universal Transverse Mercator Zone on which the image is projected. The images can be downloaded and saved in JPEG format. In addition, World Files containing the image coordinates and other information in ASCII format can be downloaded or printed out for use with GIS applications. The “Down- load” tab at the top of the screen (as shown in Figures A.4 and A.5) is selected for downloading the image shown. The image can be downloaded free of charge (see Figure A.7). The number of images that will need to be downloaded is dependent on the resolution required and the area of cover- age. The more the image is zoomed in, the greater the reso- lution and the greater the amount of visible detail. However, the user will need to download and splice together a greater number of the high-resolution images to cover a specified area. This is easily done using the World Files in GIS and CAD software, but it can also be done easily using most graphics-editing software.

TRB's National Cooperative Highway Research Program (NCHRP) Report 533: Handbook for Predicting Stream Meander Migration describes the application of a stream prediction methodology and provides illustrated examples for applying the methodology. The handbook includes NCHRP CD-ROM 48 that contains an ArcView-based data logger and channel migration predictor.

TRB’s National Cooperative Highway Research Program (NCHRP) Web Document 67: Methodology for Predicting Channel Migration documents and presents the results of a study to develop NCHRP Report 533: Handbook for Predicting Stream Meander Migration, a stand-alone handbook for predicting stream meander migration using aerial photographs and maps. A companion product to NCHRP Web Document 67 is NCHRP CD 49: Archived River Meander Bend Database, a four-CD-ROM set that contains a database of 141 meander sites containing 1,503 meander bends on 89 rivers in the United States.

A summary of NCHRP Report 533 that was published in a November-December 2004 issue of the TR News is available.
