|ENVI User's Guide: Interactive Display Functions|
Use the QuickMap feature to simplify the process of creating a map product in ENVI. You can quickly add grid lines, scale bars, titles, north arrows, declination diagrams, and logos to your image to make a quick output map. When you have set all of your parameters, you can save the settings as a QuickMap template that you can use on other images. After the output map is created, you can make additional changes with the interactive overlay capabilities (e.g., annotation) found in the Image window menu bar and you can output the map to Postscript or to a standard printer.
The following figure show an example QuickMap display.
Extremely small images may result in QuickMap displays too small to accommodate multiple annotation objects.
To use the QuickMap feature, you must have a georeferenced image displayed.
To change the map scale, enter a new value in the Scale text box, or use the arrow increment buttons.
You cannot enlarge the red box to a size that causes the output image size to be larger than what fits on the selected page size at the selected map scale.
The QuickMap Parameters dialog appears.
If you added a logo, it appears as a red box with an RGB label on the map, but appears correctly when printed.
To edit the borders, add more annotation or overlay elements, or edit the existing map elements, use standard ENVI interactive display functions as described in this chapter.
To print QuickMaps, in the QuickMap Image window, select File Print, choose Output QuickMap to Printer or Standard Printing, and click OK.
The Output QuickMap printing scales the output correctly for the parameters that you entered at the start of QuickMap. Standard printing does not take into consideration the page size and map scale you entered when you created the QuickMap.
If you selected a large page size during QuickMap setup, you might first test the output on a small scale by using the standard printing option, then use the QuickMap printing option to print to a larger page.
To output the map directly to an image or Postscript file, select the corresponding command from the File menu in the map Image window as described later in this chapter.
After creating a QuickMap, you can save the parameters in a template file to use on other georeferenced images of the same dimension and pixel size.
In the QuickMap Parameters dialog, click Save Template, enter a filename (ENVI adds a
.qm extension), and click OK.
Use QuickMap templates only on images of the same dimension and pixel size of the image from which the template was created.
To open and apply an existing map template, from the georeferenced image, select File QuickMap from Previous Template or click Restore Template in the QuickMap Parameters dialog, then click Apply to apply the QuickMap to the image.
To edit template parameters, see Setting QuickMap Parameters.
