<pre wrap="">Use Spatialite instead of using PostGIS for a start. You can move your
Spatialite database to PostGIS later on. Most of the features of
PostGIS is also available in Spatialite. Spatialite is 10x easier than
PostGIS, no server to administer.

Furthermore, the most recent version of Spatialite includes the
option to import spreadsheet tables (*.xls format). So the migration
from Calc tables to spatialite won't be so hard.<br>

<pre wrap="">I am trying to manage operations on my farm in a more scientific way, using
QGIS as a tool for making more informed decisions.
This involves mapping of points (e.g. fencepost) lines (e.g. irrigation
tube) and polygons (e.g. grazing paddock) and all related data across time,
to show in a graphic way how present configuration of resources compares to
a snapshot at any point in time past (i.e. historical facts) or future (i.e.
planning scenarios).
I am using a spreadsheet (OpenOffice Calc) to record actual data values,
build history,, and project what-if scenarios. Presuming that QGIS is the
best tool for managing vectorial data about how these facts map onto the
ground, then what is the best way of integrating data from these two
applications, i wonder?
Being not so technically inclined, i am quite apprehensive about introducing
a RDBMS into the mix (i see the PostGIS layer option available, and gather
that this enables connection to a Postgres db, which i know can host our
spreadsheet data, but…) Well: if this means there will be less hassle about
keeping data integrated between our GIS and our spreadsheets, then i might
bite the bullet and do it. What do you think?
If anyone here has anything to recommend, or any relevant experience to
share, i would be very grateful to hear about it. Thanks for listening!
Yours, Walt
