Hi,
<div><br>
<div>I’am not quite sure what processes you want automated but
if the step previously described suit your needs, then all the
steps could be incorporated into a model and this model, like
any algorithm found in « processing » can be batched.<br>

appreciate you taking the time for writing such a
detailed set of instructions.<br>
However, it is quicker for me to do it manually.<br>
<br>
If the process could be automated then of course it
would be a different matter.<br>
I am working only with the ferns - less than a hundred
records.<br>
The flower plants are over 2500.<br>

Thanks,<br>

<font face="Georgia"> As first step towards building a
model as Nicolas has suggested:<br>
I assume you have a layer with the county boundaries.
Export this layer as a CSV file, keeping only the name
of each county in the export step, and don't export
the geometry.<br>
Now open this file in your spreadsheet app of choice.<br>
Add a new column for each plant species.<br>
Put a one in that column for each county where the
species is present.<br>
Save the file (still as CSV).<br>
</font> <font face="Georgia"><br>
Open the county layer and the new CSV files in Ggis.<br>
Open the properties window for the county layer and
click on the Joins tab.<br>
Click on the "+" to add a new join. Join to the CSV
layer, and select the county names field as the join
field for each.<br>
</font> <font face="Georgia"><br>
Now your county layer has the plant species column.<br>
To display a single species, open the properties
window for the county layer, select symbology. Set the
symbology as rule based. To color just those counties
with species 1, your rule would say something like
Species1 = 1, where Species1 is the field name you
used. Pick a color/transparency of your choice, then
set the "all others" rules to be the background color
you want.<br>
</font> <font face="Georgia"><br>
That does it for one species. You can then export to
tiff or whatever. Getting it to cycle through all the
different species is for someone else to explain.<br>
