What steps will reproduce the problem?

1. Add to Map | Areas | Gazetteer polygon

2. Enter "open alpine" and select the DLC class

3. Compare Lake Eyre DLC (attached) which is "brine" with mapped "open alpine 
class" (attached).

This is an URGENT (not "Medium") problem as some may not detect an error more 
subtle than this! It could be very embarassing.

Hi Lee,

This problem is caused due to a problem with the special ingestion process that 
Adam developed to generate a contextual layer from a large gridded dataset. The 
only two layers that have been ingested using this process are Dynamic Land 
Cover and the new Land Cover Type layer that I got from AusCover.

For layers loaded via this process, a lot of data is read straight off files on 
disk where for other contextual layers it would be read from the layers 
database.

Because of this disk vs database difference, it is not possible to render 
gazetter areas for these layers in the ordinary way. So what Adam has done is 
display the entire layer that the layer belongs to, and then render it with a 
custom style to (in theory) only highlight the relevant area from the gazetter 
search. 

A problem with the generation of the custom style means that an incorrect area 
is highlighted.

I can fix the problem with the custom style, however there are a few other 
problems here:

1. The legend for the corresponding layer is displayed. e.g. the DLC legend is 
displayed when a gazetter search is done for "open alpine". This does not 
happen when a gazetteer area from other layers is displayed.

2. The hover tool displays values for the corresponding layer, even in 
non-highlighted areas. This does not happen when a gazeteer area from other 
layers is displayed.

3. The gazetteer area cannot be exported, used in an add to map/species etc. 
E.g. display "open alpine" and then try add to map/species.

I can fix the aforementioned style problem to get areas to display correctly, 
but as you can see this is only part of the problem.

Thoughts Lee and Dave?
