[Therion] Topparser

[Bruce]

Discovered Andrew's Topparser
(https://bitbucket.org/AndrewA/topparser/overview) yesterday.

A very nice concept - almost one click conversion from Pocket Topo to
Therion.  Great for saving time and ensuring consistency of file structure.

 

It creates a survey file with map definitions and drawing files with xvi,
backgrounds and empty scraps for each projection and section that was drawn
using PocketTopo.

 

It also creates a thconfig and runs it, and looks like it will open the
output and send it to a svn, mercurial or git repository.

 

I could not get it to run therion automatically (crashes apparently due to
the empty scraps - which btw I thought was fixed in 5.3.11) but if I
commented out the maps (ie hide the empty scraps from Therion) the files
Topparser created compiled perfectly.

 

A number of features don't seem to have been finished yet, but seems quite
usable as it is.

 

The first data I ran through it came up with this anomaly.

 

data normal from to tape compass clino ignoreall

#401.4  401.5    3.15      0.38      12.72    

#401.4  401.5    3.16      358.96  13.71    

#401.4  401.5    3.16      0.04      12.68    

401.4    401.5    3.157    119.79  13.04    Calculated leg from 3 above

 

Ie does not average bearings correctly either side of north.  I was using
the 1.2.0 download, but I infer from the last commit message that Andrew
might have fixed this.

 

The instructions all make sense to a Therion user, except that I still have
not really figured out the so called input and output folders.  The
instructions are not particularly explicit and the screenshot of folder
structure does not appear to match the screenshot of the data entry on page
1.

 

Minor quibbles.  I think this is worth developing further.
