map scale The ratio between one unit of distance on the map and the real-world distance it represents. For example, if a map is displayed at a scale of 1:200,000, then one centimeter on the map would represent 200,000 centimeters (2,000 meters) in the real world. The larger the second number in the ratio, the larger the area of the world that is displayed (zoomed out), and the smaller the scale; the smaller the second number in the ratio, the smaller the area of the world that is displayed (zoomed in), and the larger the scale. For example, 1:1 is life size and is therefore large scale, whereas 1:200,000,000 is zoomed out to display the whole earth and is therefore small scale. The fact that a larger second number creates a smaller scale and vice versa can be very confusing. A good phrase to remember is "as large as life" to help you remember that the closer you get to a scale of 1:1 (life size), the larger the scale is. MapTip An online help feature that displays a brief description of a map feature when you hold the mouse pointer over the feature for more than a second. See also ToolTip. Map Window File (MWF) Created with Autodesk MapGuide Author, Map Window Files (MWFs) contain the specifications of the map window. These specifications include the boundary of the map, the background color, data source information (SQL databases, spatial data files, and raster image files), layers of cartographic data (such as roads and countries), layer display information (such as styles and display ranges), and map display configuration specifications (such as menus and legends). MIF/MID file format MapInfo Interchange File, a data format that includes files created in MapInfo. You can convert these files to latitude/longitude SDF files using the Autodesk MapGuide SDF Loader. NSAPI Netscape Server Application Programming Interface, an interface that allows server applications to work with Netscape Internet servers, either Netscape FastTrack Server or Netscape Enterprise Server. If you are using one of these Netscape Internet Server as your web server, you can use either the NSAPI or CGI version of the Autodesk MapGuide Server Agent. object See map feature. ODBC Open Database Connectivity, a standard API (Application Programming Interface) used to communicate with database management systems, developed by Microsoft. OLE DB OLE DB (Object Linking and Embedding Database) provides communication between client applications and a variety of databases. pan To move the active view up, down, or sideways to display areas in the map that, at the current viewing scale, lie outside the window. paper boundary A rectangle with a drop shadow that represents the printable area. It is also called the Printable Page. pattern A property of a fill entity that consists of an artistic or mechanical design. A pattern typically incorporates lines or symbols that are equidistant from each other in the form of a matrix. For example, you could fill a polygon with a hatch pattern. point A zero-dimensional abstraction of a feature represented by a single coordinate. A point normally represents a map feature too small to be displayed as a line or area; for example, the location of a building on a small scale map, or the location of a service cover on a medium scale map.
