History of changes

Reference manual





  • Software tool for quick and assisted in-cave input of survey data (length, azimuth, slope, dimensions and note) with optional smart custom numeric keypad for stylus-free finger data input
  • Tool to draw cave walls and passage details on a metric grid displaying the line plot
  • Assisted Sketch to scale by displaying station coordinates according to the grid of the paper notebook
  • Bluetooth link to
  • Serial link to
  • Display of cave networks based on georeferences or common survey stations
  • Display and/or input of reverse azimuths and slopes (with optional averaging)
  • Line plot export in GPX or KML (Google Earth)
  • Line plot and/or sketch export in DXF (AutoCAD) or SVG (Illustrator) format
  • Altitude, lat/lon, UTM or XYZ positions may be used in location computations
  • Connected GPS tracking of current position over cave map
  • Geodesic converter
  • Flexibility to mix, within a single cave, instruments choice (including Topofil and depthmeter), measurement units, shots arrangement and direct/reverse shots
  • Optional use of survey shot series (passages) and multiple survey sessions features
  • 2 sets of current instrument calibrations (shift, precision and magnetic declination) per session
  • Cave survey data stored exactly as input into compact individual Palm OS databases
  • Caver-friendly interface (easy review of survey data, toggable use of hardware, buttons for navigation, smart auto-incrementation of new stations, backlight management, survey shot gofer, toggable warnings, folding keyboard extended support, online help, reference manual and Global Find)
  • Optimized trigonometric computations with optional persistence of resulting XYZC coordinates
  • Loop detection, display of relative closure error and expected error and actual loop closure
  • Blunder detection
  • Unlinked shots detection
  • Zoomable and pannable display of the line plot in top view and W-E, S-N, extended or projected profile views, with station XYZ or UTM locations with clipping mask and color by depth
  • On-map graphical determination of angles (azimuths or slopes) or lengths
  • Cave statistics (development, surveyed length, vertical extent, etc.)
  • IR or Bluetooth beaming of individual shots, series, sessions with/without shots and whole cave for multiple Palm OS devices cave system mapping
  • Serial, IR and Bluetooth printing of input data, computed coordinates and cave map via the XPrint System Library, courtesy of Markus Dresch/PalmSide
  • Color and high resolution (Palm or Sony) used when available
  • Menu items to toggle backlight and turn unit off (the power on button is usually unreachable while the device is in a protective case)
  • Support of Lefty, a freeware indicating the user prefers a left-handed interface (scrollbars positioned on the left side of lists)
  • Data export in tabbed CSV format or in Compass, Survex, Therion, GH Topo/Toporobot, VisualTopo or Walls format
  • Data import in Compass, Survex, Therion, GH Topo/Toporobot, VisualTopo or Walls or VisualTopo format
  • Bidirectional HotSync conduit for data exchange with Compass, VisualTopo and GH Topo/Toporobot

In the works

  • Export of line types and fills to SVG and DXF
  • Improve tolerance around sketch elements used to determine whether to display them
  • Allow zoom in Section view
  • Merge sketches after beam receive
  • Allow selecting the category after a bulk restore of caves from the memory card

Future additions

  • Inventory tool with dynamic grammar and XML export
