On-screen Digitizing
With Didger you can perform on-screen digitizing using an
imported bitmap or an image you scanned using Didger’s scanning functionality.
Performing "Heads-Up" digitizing has never been easier. Didger has all the
functionality necessary to geo-reference the bitmap image to a real world coordinate
system using one of four geo-referencing methods. Once the image has been geo-referenced,
Didger allows you to digitize points, polylines, and polygons with ease.
Extract regions and points from a
scanned topo map.
Vector Based Maps and Projections
With Didger you can import a variety of vector based maps
in many formats. Create large coverages easily by importing several vector files. The
files will align according to their coordinate systems, or can even be imported from files
with different projection systems and merged into the projection of the first file using a
datum transformation. Digitize new features onto an existing vector plot from your
digitizing tablet and map, or digitize on-screen. Import USGS SDTS Digital Line Graphs
retaining the projection information. Change line styles, object IDs, and add labels to
objects with ease. Even import different files onto separate layers!
Import USGS SDTS DDF files and retain
projection information or change to a new projection.
Geo-referenced Raster Based Maps
Import your GeoTIFF images directly into Didger 2 and
retain all the geo-referencing parameters. Digitize features from your bitmap and export
them with the image in GeoTiff format. Or, simply export the vector features without the
underlying bitmap and still retain the projection information. Use the numerous filtering
options on the bitmap to make identifying and digitizing the objects a breeze. If your
bitmap doesn’t contain projection information, calibrate the image and export it as a
GeoTiff image. Didger also supports creating ESRI World Files [TFW] when exporting
geo-referenced bitmaps. This is a powerful and advanced feature of Didger!
Import GeoTiff or any raster image, then
digitize features to export with geo-referenced parameters.
Map Projections , Coordinate
Conversions, and Image Calibration
Converting data from one coordinate system to another is
one of Didger's advanced features. With a few simple steps, Didger can transform
your Lat/Long point data into Universal Transverse Mercator (UTM) coordinates to be used
by other mapping applications. Converting coordinates by applying a simple math operation
is easily supported in Didger. This function allows the user to specify a value to add,
subtract, multiply, or divide to the current vector project. Advanced geo-referencing
conversion is also available. By specifying the source and destination coordinates of the
vector project, Didger’s advanced geo-referencing methods allow the user to convert
the current project to the new destination coordinate system. The possibilities are
endless and the flexibility is astounding!
Create stunning world maps in a variety
of projections to convey your information easily.
Advanced Editing Features
- Create line intersections from overlapping polylines.
- Snap Undershoot polylines and trim overshoot polylines.
- Create polygons by using a polygon locator in the center of
linked polyline objects.

methods.

Important News about Digitizing
Tablets
Nearly all digitizing tablets work with Didger. If you
already have a tablet, Didger requires 32-bit WinTab compliant digitizing tablet drivers,
available from most tablet manufactures (for no charge) or from third party vendors. If
you don’t currently own a tablet, you shouldn’t be discouraged. The price of
new, high-resolution digitizing tablets is astonishingly low. And with Didger’s
capabilities, large maps are easily digitized in a single project so even smaller tablets
work quite well.

Beta Tester’s Comments
"This may end up being your best product because
of its ability to use scanned images and then scale them for printing."
"I really like the design philosophy used to
create polygons from polyline segments."
"Your mixed mode digitizing is very intuitive and
will be well liked by my students. The change projection feature will be a very useful
addition to my exercises that deal with the fundamentals of projections. I am particularly
happy to see the vast improvement in error detection and correction from Didger 1. It
turned out that the biggest problem I have had with Didger 1 was the very tedious methods
by which one was forced to find small and difficult to detect errors, especially when
building polygons from polylines. It is nice to see the tolerance circles and your new set
of tools including, trimming of overshoots, extension of undershoots and creation of nodes
at intersections are very useful. Imports went smoothly. TIF is sometimes difficult due to
different "flavors" but this import (from an Multispec exported .TIF file)
worked well. I adjusted the contrast and brightness. Next, I registered the image by using
six features (road intersections) that had been located by GPS. The registrations went
smoothly and your available options in the various dialog boxes allowed for great control.
I have used layers in other programs like Mapviewer and AutoCAD. This is extremely useful
and your layer management dialog box works like most others so is not hard to pick
up."
"Nice job, one of the most trouble free
beta-version software packages I have ever tested! Also very substantial new features over
Didger 1. I am impressed!"
"Good stuff here! I'm very impressed with the
capabilities of this release of Didger. I think that with the great depth of functionality
of Didger 2, a large number of new users will find good stuff that that they can put to
good use."
"I am very impressed with the design and
functionality of this product and I know that I’m going to find it very valuable in
my work. I would also like to commend you on the high standard of the documentation. Any
procedural question that I had was clearly explained."
