Bugs and improvements

o Vastly improved sketch initial placement and morphing.

o Calulated magnetic declination shown for survey in editor
  when overall cave is "auto" calculated for information.

o Addition of reference points to sketches in editor not
  recognized as modified corrected.

****           WINKARST VERSION 12.2                      ****
**************************************************************
o Reading in SDTS, DEM, or TIF files on a different datum
  are now correctly placed relative to each other.

o Cave survey retains datum specified and not changed by
  reading in a SDTS, DEM or TIF file.

o SDTS or DEM files on lat/lon grids are resampled to UTM
  grid and properly displayed.

****           WINKARST VERSION 12.1                      ****
**************************************************************
o New geomagnetic epoch parameters for 2005 through 2010.

o DXF export in meters if survey in meters.

o Open geotiff image dialog, cancel no longer causes error.

o Open geotiff extensions with .tiff.

o Saving an survey with a geographic file (SDTS/DEM/GEOTIF)
  from the editor caused and error on second attempt.

****           WINKARST VERSION 12.0                      ****
**************************************************************
WinKarst 12.0 is available now. The two most important
improvements are support for GeoTiff files and improved
handling of Compass DAT and MAK files. WinKarst is by far the
most useful software for cave survey and mapping.

WinKarst is "shareware" with a 30-day trial period. WinKarst 
runs on Windows '95 through XP operating systems. It is 
recommended the Pentium class computer have at 256MB of RAM and
a display resolution of at least 800x600 and set to display 
24 or 32 bit color. 

A fee of $25 registers a license, previous and subsequent 
registered users can upgrade for. The update includes an 
updated help file and online pdf manual suitable for printing.

The major enhancements in Version 12.0 are

o GeoTiff
  - Read TIF images that contain geographic information.
  - Automatically place cave survey with GeoTiff map image.
  - Remove collars and place adjacent maps into composite.
  - Display GeoTiff map in Locator window.
  - Combine SDTS/DEM data with GeoTiff for shaded relief maps.
  - Write images of survey and sketches as GeoTiff files.

o Improved Compass support
  - Extract UTM coordinates from PLT files as control points.
  - Read and write Compass project files (MAK).

o Miscellaneous improvements
  - Sketches can either be PNG or TIF image types.
  - Better detection of when data is modified, not over sensitive.
  - Compass points to true north, not UTM north.
  - Prevent mixing cave survey file types.

For previous users of WinKarst, the user can install version 12.0
directly over an earlier version and it should assume your 
existing registration code. However, as a precaution, please write 
down your registration code by running the older version 
first and accessing the Registration dialog from the Help 
pull down menu. Then install the new version.

Detailed descriptions
**************************************************************
o GeoTiff
  - GeoTiff images are TIF images geographic information
    embedded in tags that specify the parameters that make
    the image a map. GeoTiff images are widely available and
    typically are USGS topographical maps or aerial photos.
  - Once the GeoTiff image is read into memory, WinKarst can
    accurately place the cave survey within the image with
    the click of a single tool bar button. The view of the
    survey can be zoomed and panned and the correct placement
    is always maintained.
  - WinKarst can optionally remove the white collar of USGS
    topographical maps, enabling several maps to be placed
    together in a composite view.
  - The entire GeoTiff image can be placed in the child
    Locator window, with the entrances of the caves marked.
    The Locator window allows the user to select smaller areas
    to view from a larger region, such as a 7.5 minute topo.
  - The GeoTiff image, topographical map or aerial photo, can
    be combined with SDTS/DEM data to create shaded relief maps.
    The resultant images can be exported.
  - The view in the main window of the cave survey on a GeoTiff
    image can be exported as a new GeoTiff image. This allows
    the user to create smaller scale images or create images
    for import into other GIS applications such as ArcView.

o Improved Compass support
  - Previously, WinKarst could only read Compass DAT and PLT
    files. When reading PLT files, if the file contained
    separate caves, WinKarst would only show the first cave.
    WinKarst can now process all parts of PLT files and
    extract control points as UTM coordinates.
  - WinKarst can now read and write Compass MAK files. This
    includes link or control points and UTM zone number. Note
    that WinKarst treats included surveys differently than
    DAT files within a MAK file. Compass assumes stations
    with the same name within different DAT files are the
    same station, whether or not they are in a different
    cave or not. Stations in different caves can have the
    same names in WinKarst.
