[Qgis-user] qgis vs grass

[Lee]

Jake,

I have used QGIS extensively for inventory, management planning, timber
sales, and similar forestry work. I think you will find it can do
everything you need it to. While ArcMap is traditionally used in our
business, the low (free) cost of QGIS presses it far past that of the
commercial products.

In regards to Forestry, I have yet to find an application where GRASS would
be more productive than QGIS. There are, however, times I have had to use
another free program called uDIG to handle various Coordinate Reference
System conversions that QGIS seems to have trouble with. That said, I think
these oddities are isolated to a small number of specific geographic areas.

In regards to Acres. There are options where you can turn your default
units to "feet". While this will not show information in  "acres", it will
give it to you in sq ft or sq miles, either of which can easily be
converted for those of us familiar with the standard parcel/property land
measurements.

I also encourage you to use the "open-layers" plugin. This will give you
several options for automatically incorporating aerial photography.
However, I have found that sometimes the "positioning" is a little off. So
use it with caution if you're attempting to outline stands or forest
property. I find myself using the regularly available 1998 ortho photos
when precision is critical.

The forestry tool-kit, is being developed more for certification and
tropical applications than traditional forest management in the sense you
and I practice. If there is the interest, I would be willing to work with
other individuals to develop a plugin more tailored to on-the-ground
resource managers. I think this is something currently lacking from the
open-source community that would more greatly enhance QGIS' adoption within
our field.

all the best,
