Hello Dave,
am I wrong or is your map connected to two distinct tables with the same
key (cat) ? then the behavior you describe may be related to a confusion
on the type of features holding 'cat' values. For exemple in the case of
a polygon map, you need to define which type of object handles
otherwise "srid" is
set to 0:
rasterlite_load -d test.sqlite -T my_raster -e 2154 -i png -f

argument) ;
