Didger 4.0

Features of Didger

  • Digitise any map, graph, aerial photo, site map, or printed image regardless of size using any Wintab32 compatible tablet.
  • Digitise a vector or raster project onscreen.
  • Digitise directly into a vector project using a GPS unit.
  • Display all the raw data being sent form the GPS unit or save it to a data or text file.
  • Average the data from the GPS over x number of sample points.
  • See the current position of the satellites that are being used for a lock for the GPS.
  • Display all GPS displays and settings.
  • View the current elevation with the GPS unit.
  • Thin and smooth objects by selecting point selection removal, deviation distance, vertex averaging, or spline smoothing options.
  • Reshape objects by adjusting individual nodes.
  • Combine, split, and/or reverse islands and lakes.
  • Merge two polygons together, or create a polygon from the intersection of two polygons.
  • Import any vector file and retain or apply up to 23 map projections. Projections supported are: Universal Transverse Mercator (UTM), State Plane 1927, State Plane 1983, Albers Equal Area Conic, Azimuthal Equidistant, Eckert IV and VI, Equidistant Conic, Equidistant Cylindrical, Gauss-Kruger/Gauss-Conformal, Lambert Azimuthal Equal Area, Lambert Conformal Conic, Mercator, Miller Cylindrical, Molleweide, Orthographic, Polyconic, Robinson, Robinson-Sterling, Sinusoidal, Stereographic, Transverse Mercator, and Unprojected Lat./Long.
  • Specify one of over 200 datums for your project.
  • Convert the projection of a bitmap in a raster project.
  • Warp, or rubber sheet, your calibrated raster image to fit any calibration units.
  • Import a georeferenced bitmap into a vector project and overlay it with other data or vector files, or tile it with other georeferenced bitmaps.
  • Add a graticule or a grid automatically to your project.
  • Display the coordinates of selected objects in the Coordinate Manager.
  • Define a polygon and use it to clip a bitmap
  • Specify up to 256 colors to be transparent for a bitmap.
  • Export directly to Surfer using the Create Surfer Base Map command.
  • Use the Create Post Map option when importing a data file.
  • Organise your data into different layers with the easy-to-use Layer Manager.
  • Select objects with And/Or criteria.
  • Resample polylines at a specified interval along either the X or Y axis.
  • Use the built-in scanning features to import a bitmap using any TWAIN compatible scanning device.
  • Import vector or raster files using any of the 27 formats that Didger supports.
  • Import data points from 9 different data formats.
  • Export vector or raster files using any of the 23 formats that Didger supports.
  • Import and export spatially referenced images including GeoTIFF, TFW, and RSF.
  • Calibrate your project using Cartesian or Projected coordinate space types.
  • Specify map datum parameters and perform datum transformations using the following methods: Molodensky, Bursa-Wolfe, DMA Multiple Regression Equations (RME), and user defined.
  • Specify projection parameters when importing data or vector files.
  • Combine vector maps from different projections into a single map projection.
  • Digitise different cultures on separate layers and export only selected layers.
  • Use Didger data with Surfer®, Grapher™, MapViewer™, or any other mapping, graphing, or database application.
  • Associate and display up to four data values or identifiers for each object.
  • Use any units (feet, angstroms, miles, meters, kilometers, etc.) with any combination of linear or logarithmic axes.
  • Determine allowable error for your project and work within acceptable standards based on statistical calibration analyses.
  • Obtain length information from polylines.
  • Obtain polygon area and perimeter length.
  • Zoom in or out to display any portion of the project.
  • Set project limits for the extent of your project, or let Didger define default limits.
  • Automatically assign IDs or assign data as you digitise.
  • Edit polylines and polygons with the numerous editing tools.
  • Define tolerance settings controlling the chaining and sensitivity of polyline and polygon creation.
  • Get immediate help for all aspects of Didger, including useful digitising examples, from the extensive online help system.
  • Use the highly accurate and simple-to-use Tablet Calibration Wizard using between 3 and 256 calibration points.
  • Receive unlimited technical support for as long as you own Didger.
  • Create and print a report of all or selected objects in your Didger project.
  • Print the entire map in full color.
  • Use the mouse, the digitising tablet pointer, or both while completing project work.
  • Enjoy over 440 Megabytes of Digital Line Graphs and Digital Raster Graphs for the Grand Canyon, Rocky Mountain, and Yellowstone National Parks included on the CD.
  • Enjoy over 80 Megabytes of boundary files, including boundaries for US 3- and 5-digit ZIP codes, US states, US counties, US State Plane delineations, US city point locations, and world countries.
