7.2.3   Map viewing options

The chief map viewing options are present as predetermined values on the tool bar. They are:

•     Zoom 100%: Graduates the zoom so the map returns to its initial resolution.

•     Movement: Allows you to move the map around the viewing screen. To do this, after you have clicked on this button, click and hold down the left hand button of the mouse and move the mouse around as you wish.

•     Zoom window: Allows you to create a zoom in window of the portion you want. Select this tool and holding the left-hand button down, draw a rectangle on the area of the map you want. When you let go of the button on the mouse, the area you marked will be enlarged.

•     Selection tool: Allows you to select different elements or areas on a map by selecting them by drawing a rectangle holding and dragging the left-hand button of the mouse.

•     Zoom out: Allows you to create a negative zoom to view the data loaded on the screen from a greater distance. Using the mouse wheel you can also increase or reduce the zoom.

•     Zoom in: Allows you to zoom in on the data loaded on the screen. Using the mouse wheel you can also increase or reduce the zoom.

•     See all: Click on this button for all the open elements (tracks, waypoints and maps) to be centred on the screen, to place them all in view. If you click on the fold-down you can choose what elements you want to be centred (tracks, waypoints, maps). This function is really useful when you cannot locate the data you know you have loaded.

•     Map scaling: Allows you to choose the percentage of increase or reduction. To do so click on the icon and select the percentage you want for the fold-down or select the option another zoom %. You can also introduce another scale in mts per pixel; this will allow you to introduce a number that will represent the number of meters that each pixel will represent.

•     Miniature view: Activate this tool and a window will open with a general view of all the open elements (maps, tracks, waypoints…). The red frame that appears represents the area in focus on the general window. This tool is very useful when you work with zooms.

•     Zoom window: Select this tool for instant 2X zoom on the area marked you mark with the pointer. This 2X zoom will be given to you in a new window that will open.

•     Projection grid: If you activate this option the projection grid (using the default values you have programmed) will be superposed on the elements you have stored.

•     Degrees grid: This option activates the latitude and longitude lines.

•     Measure distance: This option allows you measure the exact distance between any two points. To do this activate this tool then left click with the mouse on the point of origin and then move the pointer to the next point. While you move the mouse you can view the measurement reading in a small window that will appear beside the pointer. If you want to set the measurement and free the mouse, left click on the point that you are interested in. Apart from the distance between the first and second point, you will also be told the delay reading, de deviation from the North, written in degrees.

•     Turn map: This tool allows you to turn the map around however you want, situating the north in a new place. Click on this button and fill in the number of degrees that you want to turn the map.

•     Transparency: This option allows you to adjust the transparency of any map in comparison with another adjacent map. The more transparent a map is the more you will see the map below it. Moving the bar, the effect is immediate and you can regulate it as you want. Once you have obtained the correct amount of transparency click on the button ‘OK’.
