permits the relatively easy insertion of a raster image behind a vector
image (as in, for example, an aerial photo behind a GIS map). Sample

Notes about thematic maps

When you have a range of data, use a
range of color
to match the data: an increase in numerical value in the database
should correspond to an evident color increasefrom pink to rose to
magenta
to red to burgundynot from pink to orange to burgundy to yellow to
chartreuse.

When you are partitioning a range of
data, explain
how you treat gaps.

When comparing one thematic map to
another, standardize
the data partitioning procedure; if you also have another series in
which
standarization is not evident, explain.

Think about how you choose to
partition data and
explain why one choice is better than another, for your purposes.
Map your data using more than one data partitioning schemeit can give
insight into how others might choose to view your data.

You might want to save your legend as
a .avl file
(and remember to move it with the map).
