1984; Boudouresque et al., 1985b; Meinesz et al., 1988; Fredj et al., 1990; Pergent-
Martini and Pergent, 1990; Paillard et al., 1993).
The scale <strong>of</strong> maps ranges from 1/460 000 to 1/320 (Table I). Data processing may include
kriging (Francour and Marchadour, 1989; Pergent, 1990) and image processing (Pasqualini
and Pergent-Martini, 1996). A set <strong>of</strong> standardized symbols for large scale maps <strong>of</strong>
<strong>Mediterranean</strong> benthic communities has been proposed by Meinesz et al., (1983).
Table 1. Some examples <strong>of</strong> maps <strong>of</strong> <strong>Mediterranean</strong> marine vegetation (species or communities)
arranged according to scale. The scale was directly measured on authors' figures,
so that it may differ from <strong>the</strong> scale <strong>the</strong>y mentioned.
