[GRASS-user] GRASS GIS v.db.reconnect.all -cd question

GRASS GRASS user
1

Hi,

I am a beginner for GRASS. I have installed GRASS7.0Beta2 in my computer
(Win7). I am now learning that by following a tutorial on Youtube.

I know I have to rebuild the vector file in the new version since the old
vector file does not support.

I followed the
http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7

And try to do that on North Carolina sample project, but found that inputing
"v.db.reconnect.all -cd" returns me some errors "dbmi: db_list_databases()
not implemented, ERROR: Unable to list databases"

Please kindly let me know how to do that so that I could continue that
tutorial.

Thank you very much

Tianyi

Which dataset do you use here?
If the North Carolina Sample Dataset, you can download it for GRASS 7 at

http://grass.osgeo.org/download/sample-data/

I followed the
http://grasswiki.osgeo.org/wiki/Convert_all_GRASS_6_vector_maps_to_GRASS_7

And try to do that on North Carolina sample project, but found that inputing
"v.db.reconnect.all -cd" returns me some errors "dbmi: db_list_databases()
not implemented, ERROR: Unable to list databases"

Besides that it is not needed when using the package
"nc_spm_08_grass7.tar.gz", it should for sure not fail.

Any winGRASS power user here who could make a test?

Tianyi, meanwhile consider to use the updated dataset from above for learning.

Thanks for your reply! I was using North Carolina project, which is for
GRASS6, when I am using "nc_spm_08_grass7.tar.gz", it works!

But I met another question, when I try to copy "bridges" to a user1. It said
the command cannot be parsed?
<http://osgeo-org.1560.x6.nabble.com/file/n5139667/QQ图片20140511132547.jpg&gt;

I have checked the manual, the example is "g.copy
rast='soils@wilson',soils", i tried with and without ' ' , the same error
was shown. I am wondering what is the reason. Thank you again.

It should be
g.copy rast=soils@wilson,soils

Which is the manual in question? It should be corrected.

Hi, Thanks again!

I know what is the problem. I add space in the command, which makes compiler
cannot parse it. Haha. Rookie!

Is there other datasets available for GRASS7.0? It seems only NC dataset has
the GRASS7 version from the link you gave me.
http://grass.osgeo.org/download/sample-data/

How is other sample data? Like Spearfish dataset?

Regards,
TY

Perfect, solved.

Sure. I have converted Spearfish, too. Get it now from here:
http://grass.osgeo.org/download/sample-data/
--> Spearfish data set
     --> GRASS 7 (19MB)

Note that the Spearfish dataset is really old.
