| Import Georeferenced Bitmaps into Vector Projects |
Didger 3 makes it even easier to display all your data. Import a georeferenced bitmap into a vector project, and overlay it with vector and data files, or tile it with other georeferenced bitmaps!

 |
This map shows two georeferenced bitmaps overlaid with a vector file showing state outlines and a data file showing some of the major cities.

| GPS Digitizing |
Use your GPS directly with Didger 3! Enable the GPS to plot data directly on a map in Didger or save the GPS data to a text file. View the GPS settings in the GPS Commander dialog box.
|
|
 |
View current elevation, see current position of satellites being used for a lock, display the raw data being sent from GPS, and set GPS input datum in GPS Commander.

| Image Warping |
|
Warp or rectify a bitmap in a raster project! Calibrate the image in a raster project, then use the Warp Image command to rectify the image to match the calibration points. |
|
 |
Warp your image to fit any calibration. Image warping (also called rubber sheeting) is an important feature in Didger 3. Image warping can correct map or image distortion.

| Add a Graticule or Grid |
|
Make the locations of your maps easy to determine by adding a graticule or grid to your vector project. The map below shows North America in the Mercator projection. |

| Enhanced Layer Manager |
Increase the organizational potential for creating and maintaining different layers with the enhanced Layer Manager. The Layer Manager is "always on" to make accessing the layers simple.
|
|
 |
Having the Layer Manager on the side of the Didger window makes accessing the layers simple and easy.

| Coordinate Manager |
Display all the coordinates of a selected object in a raster project in the Coordinate Manager. If you are in a vector project, you can also edit the coordinates within the Coordinate Manager.

| New Bitmap Clipping Options |
Bitmap clipping greatly enhances the ease-of-use when working with bitmaps. Two new bitmap clipping options are introduced in Didger 3.
USGS DRG files often have map collars, which contain information about the bitmap. When two or more of these bitmaps are imported into a vector project, it may be undesirable to see this information. Simply select the bitmap and clip the map collar.

 |
Clip the area outside of the main map on a bitmap in a vector project.

You can also define any polygon on a bitmap and then use that polygon to clip the bitmap. This is helpful in showing specific areas of interest.
