Digitizing
Options
There are three ways you can digitize
information from your source documents or files. You can digitize hard copy
documents using any Wintab32 compatible digitizing tablet. You can digitize
digital information, such as vector or raster files, onscreen. You can also use
your GPS unit to digitize your position or trace your route directly onto a map
imported into a vector project!
Raster
Based Maps
With Didger you can perform onscreen
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 import or scan in a
bitmap and calibrate the image in real world coordinates using one of ten
georeferencing methods.
Once the image has been calibrated, Didger
allows you to digitize points, polylines, and polygons with ease. You can export
the digitized objects with the image in GeoTIFF format. Or, simply export the
digitized objects without the underlying bitmap and still retain the
georeferencing information. Use the numerous bitmap filtering options on the
bitmap to make identifying and digitizing the objects a breeze.
The graphic above shows the
boundary of the Modoc Plateau in Northern California being digitized in blue
from a calibrated raster image of the geology of California.
Georeferenced
Raster Based Maps
A georeferenced raster image retains all
georeferencing parameters. When you import a georeferenced raster image, you can
skip the calibration process and start digitizing immediately. You can import a
georeferenced raster image into a vector or a raster project.
If you import a georeferenced bitmap into a
vector project, you can overlay it with other data or vector files or tile it
with other georeferenced bitmaps.
Import georeferenced
bitmaps into a vector project and then overlay it with data and vector
files.
If you import a georeferenced bitmap into a
raster project, you can convert the projection of the bitmap (if it contains a
projection) or you can warp (rubber sheet) the image to fit your calibration
points.
Import a bitmap into a
raster project, calibrate it, and warp it to fit the calibration points.
Didger also supports importing and/or
exporting ESRI World Files [TFW] and Blue Marble [RSF] files when exporting
georeferenced bitmaps. This is a powerful and advanced feature of Didger!
Vector
Based Maps and Data Files
With Didger you can import a variety of vector
based maps and data files in many formats. Create large coverages easily by
importing several vector or data files into one project. The files will align
according to their coordinate systems. Digitize new features onto an existing
vector plot from your digitizing tablet and map, or digitize onscreen. Change
line styles, object IDs, and add labels to objects with ease. Even import
different files onto separate layers!
If the files are projected and contain
different projection information, they will be converted to the projection of
the first imported file using a datum transformation. You can also convert
vector or data files from one projection to another.
This graphic shows three
vector files and a data file imported into a vector project in the Lambert
Azimuthal Equal Area projection.
Map
Projections and Coordinate Conversions
Converting data from one coordinate system to
another is one of Didger's advanced features. Didger supports over 20
projections and over 200 datums. Easily calibrate or import your files using one
of these projections and convert your coordinates between them. For example,
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. All supported projections include:
Albers Equal
Area Conic |
Orthographic |
Azimuthal

In addition to projection and datum
transformations, Didger can also convert coordinates of vector projects by
utilizing either a math or georeference operation. Converting coordinates by
applying a simple math operation allows the user to specify a value to add,
subtract, multiply, or divide to the current vector project. Advanced
georeferencing conversion is also available. By specifying the source and
destination coordinates of the vector project, Didger’s georeferencing methods
allows 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. The graphic above
uses the Equidistant Conic projection.

Important
News about Digitizing Tablets
Nearly all digitizing tablets work with Didger.
If you already have a tablet, Didger requires a 32-bit WinTab compliant
digitizing tablet driver, 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.
