Land in the USA is described by 'metes and bounds' measurement. So anyone
doing GIS landwork has to convert this legal description to polygons.
There are some packages out there for ArcView, but none in the Linux
domain.
More on 'metes and bounds' -- "A parcel boundary is commonly defined by
its relationship to some point of beginning (POB) by metes and bounds
(north 23.5 degrees 350 feet thence east...) or by aliquot parts (e.g.,
the northern quarter of the southern quarter of Section 1 Township 1 Range
2)."
I work in a Oil and Gas data warehousing company. No O&G company can use
GRASS to handle their landwork until this issue is solved. Some landmen
use AutoCad's plug in to convert it then export.
My company would be interested in partially or completely funding this
module/plugin depending on how many manhours it would take.
"A simple utility for converting bearing and distance measurements to
coordinates and vice versa."
I suppose a good check for the module would be to run it for a closed loop
and check that the endpoint matches the starting point. Probably have to
do that with fake data as what is printed on a survey sheet might not be
exact which may lead to small circuit errors.
Yes, it looks like m.cogo would be the core of the solution. A complete
GUI friendly solution would be to be to launch the module and the first
thing required would be to set the POB on a layer, then be prompted to
type in the metes and bounds, have it offer what degree notation should be
used (whether 30'45", 30:45, or 30.75).
Then it would create the polygon right there in the layer.
