 in Open Source

 Review of the state of two
     opensource mapping
      clients available
        on fc13


qgis:  sigsef when I run it from intall 
from fedora yum repository.  Try to compile it
and I don't get anywhere.

qlandkarte
this will run, but it loads no data.
hints at websites say you usually need
to 'buy' the data.  And there are no
samples.  Is this yet another opensource
project hyjacked by marketting and
sales to be useless unless bundled
onto a cell phone?

Here are the three types of data that
can be loaded (from the menus):
GPS-Exchange
Geochachng.com Easy GPS
MapSource

Here are two map options (from the menus):
load map
import map

As often in opensource, there is nothing
 that explains anything. No help, nothing.


And, as is typical in the case of many things
 that were once 'free to use' the project 
is 'dead', as stated on the following URL:
http://qlandkarte.sourceforge.net/

.  And the 'future' is listed as a fork of this:  
qlandkartegt

qlandkartegt

  The forked project is also available in the fc13
 yum repository.  However, it, as well as qgis
 does not work.  It sigsefs.  Probably for the 
same reason.

More on this in a future column.

You can, of course, use mapperelli for maps
of parts of New England and California.
This is still free to use from my website at
the following links:


The glorious Upper Valley (of VT and NH)

Mapperelli Demo Centered on Lake Tahoe

The one and only Mt. Ascutney

The very famous Mascoma Lake

Clairmont, NH

Morgan Pond, NH
