comment Determining Natural Origin for a GeoTIFF file (Lambert Conic)
Well, it came off that way to me, at least. My response also comes from my experience having only used False Origin in SP2. That was confirmed by the ESPG Guidance doc in Table 2 on p 15: it suggests only SP1 uses Natural Origin. Check p. 18 -- visually compares false and natural origin calculations. Search for False Origin and Natural Origin -- there are a couple good examples I read there.

comment Determining Natural Origin for a GeoTIFF file (Lambert Conic)
@BradHards Frustrated or not, please be a little bit more respectful of my attempt to help. If the answer is wrong, don't accept it. I did not realize my link was also EPSG Guidance Note 7 Part 2 -- but that document does show calculations with Natural Origin and False Origin -- why does it matter that they are not called lambda0? If doing the back-calculation gets you the wrong coordinates, either your math is wrong or the header is confusing this FalconView (I just threw out a suggestion that it could be an SP2 vs. SP1 issue -- I do not have a user guide myself!) Cheers,

comment How do I make a heat or Choropleth map that uses polygons in QGis?
Thumbs down to anything manual in qgis -- especially once you starting dealing with //tons// of shapefiles, you could end up in a really frustrating position. You will not regret using your SQL-fu, be it with postGIS plugin or GRASS plugin (see my answer below: gis.stackexchange.com/a/42188/7689).
