Didger Suite   圖形數位化軟體

A contour map was scanned, saved as a grayscale image, and imported into Didger 4 (left).
The image was automatically vectorized to red polylines (right).

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!

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!

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!

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!

New Fill Patterns and Line Styles!
Create your project exactly the way you want! Fill areas with one of the new picture or USGS fill patterns, use one of the many new line styles.

Convert a Polyline to a Polygon with a Shared Border!
Easily create a polygon with a shared border! Simply draw the first polygon, then use a polyline to define the next polygon. Use the Polyline to a Polygon with Shared Border command to convert the polyline to a second polygon! The shared border will be automatically created.
