Is a highly accurate digitizing program that will be an invaluable addition to your software library.
In seconds, Didger precisely transforms points, lines, or areas from your paper maps, graphs, aerial photos, scanned raster images, imported vector files, or GeoTIFF images to a versatile digital format you can use with your other software. You name it and Didger can handle it quickly, accurately, and usefully.
With Didger’s multitude of features and ease-of-use, this is an unbelievable value, considering the time and effort you will save!! You will soon wonder how you have done your job without this indispensable tool.

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 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 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.
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.
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.
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.
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!
