 Example taken from a workshop material:

 {{{
 from grass.pygrass.vector import VectorTopo
 from grass.pygrass.vector.geometry import Point
 point1 = Point(635818.8, 221342.4)
 point2 = Point(633627.7, 227050.2)
 cols = [(u'cat',   'INTEGER PRIMARY KEY'),
 (u'name',  'TEXT')]

 with VectorTopo('my_points', mode='w', tab_cols=cols, overwrite=True) as
 my_points:
 # save the point and the attribute
 my_points.write(point1, ('pub', ))
 my_points.write(point2, ('restaurant', ))
 # save the changes to the database
 my_points.table.conn.commit()
 }}}

 gives:

 {{{

 Works in 7.0.4.

[GRASS-dev] Seeking advices for image segmentation algorithms and windows compile question

[Yang, Bo (yangb2)]

Hello,

This is Bo Yang from the University of Cincinnati. I am working with Moritz and 
Markus for the GSoC 2016 project-- Additional segmentation algorithms for 
i.segment [0]. Currently, the i.segment module only provides one segmentation 
algorithm: region-growing. The code of i.segment was structured in a way that 
allows addition of other algorithms. I plan to add

More algorithms such as mean-shift and watershed.  To prepare for it, I 
searched some literatures about both algorithms below, I'd like to consult if 
anyone have more recommended references.



Mean-shift:

Comaniciu, D., & Meer, P. (2002). Mean shift: a robust approach toward feature 
space analysis. IEEE Transactions on Pattern Analysis and Machine Intelligence, 
24(5), 1-37.



Watershed:
Shafarenko, Leila, Maria Petrou, and Josef Kittler. "Automatic watershed 
segmentation of randomly textured color images." Image Processing, IEEE 
Transactions on 6.11 (1997): 1530-1544.
Haris, Kostas, et al. "Hybrid image segmentation using watersheds and fast 
region merging." Image Processing, IEEE Transactions on 7.12 (1998): 1684-1699.


In addition, is there anyone who use win10 OS to compile the GRASS? I have 
compiled GRASS in window 10 64bit system followed the tutorial [1]. In last 
step of the tutorial it mentioned:

>Usage:

>To start GRASS use the icon on the desktop or if you want to 
be able to use the command line from within GRASS.

>Type in cmd console (assuming that we compiled GRASS 7.1):

>c:\osgeo4w\bin\grass71svn.bat

However, No matter I use CMD console or the OSGeo4W Shell. I got the same error 
below:

'""' is not recognized as an internal or external command, 
operable program or batch file.
>From the error.log there is no error during the compiling. There is no error 
>reported in former steps either, and I can see the file " grass71svn.bat " is 
>located in the right place. But I still can't start the compiled GRASS. I 
>Googled this error but can't find helpful information. Any suggestion would be 
>greatly appreciate.

P.S. scripts in grass71svn.bat:
@echo off

rem # GRASS initialization bat script (OSGeo4W)

Re: [GRASS-dev] Work around for bug causing profiler and histogram to crash in GRASS 7.1 64bit wxPython 3.x

[Michael Barton]

Sure. 

Here is a recent stack exchange for this problem. Supposedly it is fixed in 
wxPython 3.0.3.

http://stackoverflow.com/questions/30383786/wxpython-wx-lib-plot-plotcanvas-error

And here is the patch to fix plot.py. 

http://trac.wxwidgets.org/attachment/ticket/16767/wxPython-3.0.2.0-plot.patch

It is pretty minimal effort to make the changes, so I patched my local version 
of plot.py, which is deeply buried on my Mac in:

/usr/local/lib/wxPython-3.0.2.0/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/lib/plot.py
 

Then I recompiled GRASS and rebundled the patched wxPython with the 64bit GRASS 
app.

Could you tell us what this workaround is ?
