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.

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!

Geo-referenced Raster Based Maps

Import your GeoTIFF images directly into Didger 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!

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!

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.
