      'RangeMapper 2.0', to be released by Tundra Vole Software
(Fairbanks, Alaska) this spring, is a Macintosh mapping and data
plotting program de-signed  specifically for making species
distribution maps from your own files of latitude/longitude data
for collection sites. Digitized mapping data files for the world
(low resolution) and North America (higher resolution) are
included. Northern Alaska, and California, are available with even
higher levels of hydrologic detail in add-on files.


      The resolution in the world files is suitable for mapping
areas down to a few hundred miles in extent. The resolution in the
North America files (which include Greenland, eastern Russia,
Central America and the Caribbean islands) can handle areas down to
40 miles or so in extent. Similar files for Europe are in
progress--other continents will follow.
      The mapping files contain: coastlines, islands, lakes, rivers,
international borders, and US state and Canadian province borders.
Additional files contain US county borders, and approximate files
for Mexican and Central American state/province/district borders.
The world files show only a few major rivers and the largest
lakes--the North American files have more hydrologic detail (and
are derived from the CIA World Data Bank files). The high-detail
files for California and northern Alaska are derived from the USGS
Digital Line Graph files--more states will be available later.
      Mapping can be done in any of seven map projections: N and S
polar azimuthal, cylindrical, Mercator, orthographic,
stereographic, and Lambert azimuthal equal-area. On a Mac II it
takes about 40 seconds to plot a map.
      Hydrologic features in the North America file (rivers, lakes,
islands) can be highlighted on maps by name. Nearly 6000 named
features are in the gazetteer.
      Plotting data files for 123,500 U.S. populated places are
included, as well as approximate county centers (which latter may
be used to automatically fill counties by name--another way to
present county records).
      RangeMapper can read ASCII textfiles of latitudes and
longitudes in a number of formats, and plot these to its maps as
various sizes of open or filled squares or circles--or as 3-D bars
whose heights are controlled by a third variable, letting you
display the geographic variation of quantitative information.
Fourteen indendendent layers of data may be plotted to a map. The
allowable formats include tab-delimited decimal degree files, which
means RangeMapper can read files exported from spreadsheets or
      A user-designed lat/long grid can be overlaid on any map.The
maps can be saved, printed directly from RangeMapper, or exported
as PICT files to be opened in Canvas or SuperPaint and enhanced,
labeled, etc. The resulting maps can be imported into your own word
processor documents.
      Lat/long coordinates may be read off the screen in any
projection. Questionable plotted points can be queried, and the
plotting data file can be interactively edited from within the
program. RangeMapper can be used to 'grab' lat/long coordinates
from published distribution maps for incorporation in your own
maps, provided the published map has a lat/long grid shown.
