[postgis-users] ST_AsBinary

[Paragon Corporation]

Mike,
 
Thanks for the tip.  Is there any way to render the Z coordinates aside from
the info panel.  We don't have too many 3 D examples in the book (and much
of the book is already finalized), but in the PostGIS Raster chapter we are
in the middle of rewriting we do have an example that converts a 2-D
linestring into a 3 D linestring by intersecting with Raster elevation data.
Would be nice to have a 3D representation of it.
 
Thanks,
Leo and Regina

Hi,

Thanks for the link. Very interesting faq indeed.
If you think it can be useful for the faq or for your book, I suggest to add
examples using As_EWKB instead of As_Binary to get data from PostGIS with
OpenJUMP as it seems to be the way to go not to loose z ordinates.

Correct.  In fact we even has this as our #1 FAQ for 1.5

Hi Ravi,

Did you try to update your jdbc driver ?

Again, there is a link here to download it :
http://jdbc.postgresql.org/download.html

You should download
http://jdbc.postgresql.org/download/postgresql-9.0-801.jdbc3.jar
<http://jdbc.postgresql.org/download/postgresql-9.0-801.jdbc4.jar> 
Then, you have to go in your OpenJUMP intallation directory and replace 
postgresql-8.3-603.jdbc3.jar
by
postgresql-9.0-801.jdbc3.jar

If you're using java6, you should be able to use 9.0-801 JDBC 4
<http://jdbc.postgresql.org/download/postgresql-9.0-801.jdbc4.jar>  instead
of 9.0-801 JDBC 3
<http://jdbc.postgresql.org/download/postgresql-9.0-801.jdbc4.jar> 

Note that I haven't yet install postgresql 9.0 to check everything is fine,
but it comes from a discussion I had with postgis developpers that something
changed in the postgresql 9.0 byte array format, which is the reason why a
new driver is required.

Hope that helps

Michaël

Other that OpenJUMP, suggest which FOSS4G tool can be used.
