Didger 4.0
Introduction
Didger is a highly accurate digitising program that 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.
There are three ways you can digitise information from your source documents or files. You can digitise hard copy documents using any WinTab32 compatible digitising tablet. You can digitise digital information, such as vector or raster files, onscreen. You can also use your GPS unit to digitise your position or trace your route directly onto a map imported into a vector project.
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 utilising 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 allow the user to convert the current project to the new destination coordinate system.
