What is
Biotas:Biotas is a software
program for Windowsฎ 95/98/NT that was written as a statistical and
GIS tool for ecologists and resource professionals. This program has
been designed to assist in the analysis and understanding of spatial
and temporal data from biogeographical and ecological studies
including, but not limited to, those dealing with wildlife,
fisheries, plant or animal ecology. Components of Biotas have been
written to enhance the analysis and interpretation of data across a
wide range of landscape and temporal scales.

GIS and
Statistics:As a GIS program Biotas
can import coverages for visual display or incorporation into
analysis. Biotas goes beyond simple GIS by integrating spatial and
temporal statistical analyses and simulation capabilities.

File
Formats:Biotas accepts
locational data (also known as point pattern data) as either query
files or database tables in either *.dbf (DBase), *db (Paradox),
*.xls (Excel) or ASCII file formats. Full SQL (Structured Query
Language) use is supported as are full date and time variable
formats. Biotas exports locational data variables in ASCII, *.dbf,
and *db formats, as well as Windowsฎ clipboard copy and paste
functions. Data matrices for preprocessed quadrate data will also be
supported. Importation support for coverages currently is limited to
ArcViewฎ shape files and *.dxf files. Biotas currently exports
coverages (such as generated home range contours) as ArcView Shape
files, ArcInfoฎ compatible text files or as *.dxf files. Biotas
import and export functions will also eventually include other map
file formats.
