[Talk-ca] StatsCan Address Ranges in OpenJUMP -- how to interpret them?

[Dan Putler]

Hi Tyler,

OpenJUMP probably isn't the tool to do this with. Three tools come to
mind: (1) using ogrinfo from the GDAL/OGR library (which if you are
Windows user is most easily obtained via FWTools); (2) a spatially
enabled DBMS such as PostgreSQL with PostGIS, which would enable you to
get at the nodes of the polyline ("way" is an OSM coined term, and not
used in traditional GIS, but in open source GIS, most folks will know
what you mean when you use the term "way") since you can access the
geometry column (the_geom in PostGIS) in these systems; and (3) through
the sp package in R, but unless you are an R user for other reasons (it
is a statistical computing environment), it won't be your first choice.

Its do-able, but probably not as easy as you had hoped.
