B. MAPPING -GST MAPPER <br />I. Map Data <br />ESRI Compatibility: GST Mapper® is ESRI compatible. All GIS data in ESRI <br />shapefile format can be incorporated into the system without conversion. <br />However, since shapefile does not contain network topology, the street centerline <br />shapefile does not support routing functions unless the shapefile is processed to <br />generate additional files for network topology. If routing is desired, street <br />centerline is the only shapefile that needs to be processed into a proper format. <br />Multiple Data Layers: GST Mapper® supports any number of data layers as long as <br />enough disk space is available on the hard drive. <br />Multiple Data Types: GST Mapper® supports multiple types of GIS and image <br />data, including standard street centerline, point features, line features, polygon <br />features, aerial photography in ECW format, images in commonly used format <br />such as JPG, and documents in pdf format (Acrobat reader required to read pdf). <br />Coordinate System: For GPS real-time tracking, GST Mapper® supports standard <br />GPS native coordinates in Lat/Long NAD83 format. <br />2. Mapping Functions <br />Standard Mapping Features: GST Mapper® provides standard mapping tools <br />including zoom-in, zoom-out, pan, center map by clicking on any position of the <br />map, and center map by entering Lat/Long coordinates. The zoom-in tool allows <br />the user to click and draw a rectangle to zoom in to the defined box. The user may <br />pan the map by pressing direction keys or dragging the mouse in any direction. <br />Scale Control by Layer: GST Mapper® allows each map layer to be set at a <br />different scale for display and labeling. At any user-set scale, each layer can be <br />automatically turned on/off. The user may change the setting at any time. <br />Scale Indicator: The map scale is displayed at the bottom of the map window. <br />Cursor CooMinates: At any time, the Lat/Long coordinates of the cursor position <br />are displayed at the bottom of the map window. As the cursor moves, the <br />Lat/Long coordinates change automatically. <br />Attribute Display: A button allows the user to click on a selected feature to display <br />its attribute information. <br />Map Annotation: GST Mapper® provides a set of annotation tools to allow the <br />user to draw points, lines, polygons, and add text to the map. The annotations can <br />be saved in a file for future use or be shazed with other users. The user may open <br />Copyright GeoSpolia! Technologies, rne. 2 <br />
