New Versatile Image Calibration!

There are more ways than ever to import and calibrate your images. Calibrate an image either by entering coordinates manually or by simply clicking on points in your existing project! Alternatively, you can import the image un-referenced so you can move it around your project with your mouse! Your images have never looked so good!


 

We have streamlined the image calibration procedure so that it is more intuitive and faster than ever to calibrate your images.
You can choose to calibrate an image based off three or more points that you can enter, or you can simply tie points in
your image to locations in your current project!






Large Image Handling and MrSID Compatibility!

Didger 4 contains the most sophisticated and advanced image handling routines so you do not run out of memory when working with large image files! Importing multiple images and creating large mosaics and coverages is a snap. You even have the option to directly import MrSID files, making it even easier to work with large images!?


 
Create and export large image coverages easily with Didger 4!?
Improved memory handling gives you the most control when using many large images at once.
In this example, seventeen USGS Digital Ortho Quarter Quads (DOQQs) were overlaid.





Wrapped Polylines for Digitzing Well Logs!

Digitize your entire well log in one step, including the wrapped portions! Didger gives you the power to digitize logs that have curves off scale!?


 
Easily digitize wrapped polylines from well logs! With a press of a button,
you can toggle between two different scales.





More Attributes for Your Data!?

Import and export all of your data! Didger now supports up to 256 data attributes per object to give you even more control of your data.


 
Create up to 256 attribute fields and name them anything you wish and for your Didger project!
Specify any of the attribute fields to be the Z-level field for exporting to Surfer or to a 3D DXF or SHP file.
You can even save the attribute definitions to a file for use in other projects!




Surfer Compatibility!?

Now it is easy to see your maps the way you want them! Automatically digitize contour or other 3D data in Didger and send them directly into Surfer with a click of a button to change contour properties, overlay with 3D terrain surfaces, DEM files, or other 3D imagery. Didger also makes it easy to directly convert the projection Surfer GRD or DEM files, so you can have all your maps in the same coordinate system in Surfer!


 
Digitize your information, recording the Z value and automatically create colorful contour?
image, or shaded relief maps in Surfer!




Easily and Consistently Format All Objects On A Layer!?

Set the drawing properties in any layer to be based on a keyword or numeric range found in one of your ID fields! Now you do not have to go through the time consuming process of repeatedly selecting or creating certain objects and assigning the same properties to them. It has never been this easy to create consistent looking projects!


Choose to format all objects on any selected layer the same way! In the example above,
all objects will be formatted based on their Primary ID value.
All objects with a Primary ID of 밼orested areas?
will be formatted using the fill, line, and symbol properties shown to the right.
Just select the Primary ID in the list on the left and choose properties for that group of items on the right.
You can add or remove items from the list on the left, or you can have Didger automatically create the list!
Save the formatting specifications to a file for use with other projects!

What major new features are included in Didger 3?

We have compiled a list of the top new features in Didger 3. This list is only a small sampling of the new features added to Didger 3.



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 your current elevation, see the current position of the satellites that are being used for a lock,
display the raw data being sent from the GPS, and set the GPS input datum in the GPS Commander dialog box.



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.

Add a graticule or grid to your vector project.


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.

Edit the coordinates of selected objects in a vector project using the Coordinate Manager.


Convert the Projection of Your Bitmaps

Didger 3 allows you to convert the projection of a bitmap in a raster project.

Import a bitmap into a raster project, calibrate it, and then convert the projection into any of the 23 supported projections.
The map above was calibrated in Unprojected Lat/Long and then converted to the Albers Equal Area Conic projection.

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 and reducing the file size of the Didger project.

Define a polygon on any bitmap and use it to clip the bitmap.


New Import/Export Formats

Didger 3 has added some new import/export formats to the already extensive selection of import/export formats available:

Vector File Import formats: Golden Software Interchange (*.gsi), and Windows Metafile (Enhanced) (*.emf)

Raster File Import format: Portable Network Graphics Bitmap (*.png)

Data File Import formats: Excel Spreadsheet (*.xls), Microsoft SYLK (*.slk), Lotus 1-2-3 and Symphony (*.w??), Atlas Boundary (*.bna), and Golden Software Blanking (*.bln)

Export format: LAS format, Golden Software Interchange (*.gsi)


Additional New Features

  • Export bitmaps from vector projects when using the Create Surfer Base Map command.
  • Export a project in any of fourteen coordinate units!
  • Use the "And/Or" functionality with Criteria Select.
  • Use the new Create Post Map option when importing a data file.
  • Select up to 256 colors to specify as transparent for a bitmap.
  • Use the new Pan tool to move the plot around in the plot window.

Beta Tester's Comments

  • "I do aerial photography and I am enthralled by the warping/rectification abilities of Didger. That is a very useful tool that I will make good use of. To me, that alone is worth the price of the package."
  • "Digitizing directly from real-time GPS data is a great new feature among an impressive list of Didger 3 capabilities."
  • "The Coordinate Manager will be extremely useful for correcting tablet-based features for which real world coordinates are actually known. I will use it often!!
  • "I really like the ability to convert the projection or a raster project and the ability to choose a UTM datum when projecting a file."
  • "The Layer Manager is the great tool in Didger, and now it is even easier to work with."
  • "I will definitely use the Graticule and Grid feature. I usually use State Plane coordinates and this allows me to identify the 10,000 ft grid lines I normally use."
  • "Didger has to be one of the most user-friendly programs I've ever dealt with. It's ease of use for digitizing over ArcView or AutoCAD is phenomenal!"
