Then, right-click on the location and select Drop Marker Here. A geographic marker is placed at the location and the latitude and longitude for the location are saved. Pick Next to display the Geographic Location-Set Coordinate System dialog box, which allows you to select the coordinate system and time zone. Select the appropriate coordinate system and then pick Next. This switches you back to the drawing, where you can specify a point for the geographic location in the drawing. After picking a point, you are prompted to specify the north direction. Pick a point that should be in the north direction, enter an angle, or use the First point option to pick two points that defi ne an angle. Once this is set, a geographic marker is added at the selected point and the online map is displayed in the background. The geographic marker looks like a red and white thumbtack. See Figure 18-8A. The Geolocation contextual ribbon tab appears once you specify a geographic location. See Figure 18-8B. The options in the Location panel allow you to edit the location and orientation of the marker or remove the location from the drawing. The Locate Me button is available in the Tools panel if your operating system is confi gured with location sensing features. Picking the Locate Me button places a marker in the drawing to indicate your current location. The Mark Position drop-down list contains options to mark other positions on the map. You can mark a position by specifying the latitude and longitude, picking a point, or specifying your current location. Once you specify a point, you have the option to enter multiline text to label the point location. Type the text and exit the multiline text editor. If a visual style other than 2D Wireframe is current, a yellow position marker is displayed. The position marker includes a point object with a leader attached to the label text. The map image drop-down list in the Online Map panel provides options for controlling the appearance of the map in the background. A map can be displayed as an aerial image, a road map, or a road map overlaid with an aerial image. The options in the map capture drop-down list in the Online Map panel allow you to select a portion of the map and embed it into the drawing. Once you capture a map image, you can display and plot it even if you are no longer connected to the Internet. The Capture Area option prompts you to defi ne a rectangular area to capture. The Capture Viewport option captures whatever is displayed in the viewport. Selecting one of these options from the ribbon initiates the GEOMAPIMAGE command. To use this command, you must fi rst change to a plan view of the WCS.
