Well,
after a few days testing, I narrowed it down to 3 possibilities:
1. Make a separate map sheet, import the GIS shapefile containing the mosaics.
Assign this polygon to new locations then import the NVC species & habitat .dbfs onto that.
2. New Survey: NVC. Import scant species records into it with only one column representing each NVC main community. There is no way I can see to import sub-communities without some major tweaking of the .dbfs.
Run a snapshot based on this survey & extrapolate it within GIS
3. Load everything into GIS and be left with less species records.
Option 1 has been dismissed as too much like hard work: 100 NVC surveys, 51 Reserves, around 20k records.
Option 3 will reduce the amount of biodiversity data within our R6 Database & thus ultimately onto the NBN.
So am going with option 2. Did a trial upload of 800 species records last night & everything appears to be working well.
Will still like to hear how other folk approach this issue together with any ideas for importing biotypes without species records.
