National and international organizations are developing spatial databases to assess the
distribution of Biodiversity using geographic information systems (GIS). Currently, there
are no guidelines or standards for building GIS databases for biodiversity assessment
because database design is discipline-dependent and most biodiversity disciplines lack
spatial traditions. The present research analyzes the conceptualization of biodiversity
information at the spatial level and discusses its relationship to the modeling and
structuring of data in GIS databases. The relevant findings of this research are: 1) the
degree of data processing in the original sources has to be acknowledged in the design of
the spatial model and data structure of the biodiversity database theme, and 2) the spatial
uncertainty of biodiversity data is related to the georeferencing method, the classification
label (taxonomic, physiognomic,etc) and the ecological context
