  • MapGuide Drawing Tools

    Overview

    Most of our MapGuide maps include drawing options and other map tools in the "Map Tools & Map Info" drop-down menu at the top of the map. These tool options are only available using Internet Explorer on Windows. They are not shown on other platforms.

    The drawing tools are:

    • Draw Point
    • Draw Line
    • Draw Circle
    • Draw Polygon
    • Draw Text

    Using the Drawing Tools

    You can use the drawing tools to draw on the MapGuide map for whatever special needs you have. You can then print the customized map or copy it into another document. You might want to do this for presentation, display, or to illustrate a particular point. You can also buffer these drawn map objects or select map features within them as explained later.

    While MapGuide can be very useful for printing maps, it's primary purpose is interactive viewing, not making printed maps. Likewise, these point, line, circle, polygon and text drawing tools on our maps are not a substitute for more powerful graphic programs such as Adobe Illustrator. Even so, you may find the drawing tools handy as you can draw directly in the map itself.

    These drawing tools within the MapGuide map not only change the appearance of the map, they actually create map objects (map features) that display and act like any other map objects on the map. These map objects appear at the top of the legend in layers called "Points", "Lines", "Circles", "Polygons" and "Text". Symbol and text sizes are specified as distances in map units "on the ground". Specified sizes are not screen measures or sizes on map printouts.

    You can create any number of points on the map, but they will all be in the one "Points" legend layer. The same is true for lines, circles, polygons and text you draw. All lines are in the legend "Lines" layer, all polygons are in the "Polygons" layer and so on.

    Whatever you draw on the map stays on the map only for the duration of your map session. If you close the map, everything you added is lost. There is no way to save your drawings in the map. If you want to save your work or if you want to use more sophisticated drawing tools, then print the map or copy it to the clipboard (right-click Copy, Copy Map) and paste it into another application to save the map. For instance, you could use Microsoft Paint, Microsoft Word, or Adobe Illustrator, etc.

    Since your drawing is added to the Points, Lines, Circles, Polygons and Text layers in the legend, you can turn those layers on and off just like any other legend layer to remove them from the map view or put them back in the same map session. If you want to delete all the drawn map features, you can exit the map and restart or simply use Internet Explorer's Refresh button to refresh the map.

    You can remove the Points, Lines, Circles, Polygons or Text map features by opening the corresponding map tool and using one of the two "Remove..." buttons. First, there's a "Remove Selected..." button that allows you to remove one or more drawn drawn map objects that you've selected on the map. Second, there's a "Remove All..." buttion that removes all draw map objects of that type. Or, to remove everything you've drawn, you can refresh the map and start over, removing all drawn points, lines, circles, polygons and text. Don't forget that you everything you draw is lost when you exit the map or log off.

    Map Objects and Buffers

    Since you draw actual map objects, they act like any other map objects. This enables the powerful ability to create buffers around one or more selected objects you have drawn. You can even select both regular map features and one or more map features you have drawn and buffer them all at the same time, creating one buffer from the mix of map objects. From there you could select the buffer area and then map objects within the buffer area like any other buffer and create mailing lists from parcels, etc. For general help on selecting map features, see See Selecting Map Features in the MapGuide Viewer Help but be sure to scroll down on the page to see the most commonly used methods.
