Hola Erwan :-)<br>
<br>
Thanks for your help, I'll take a look and keep an eye on it. I can
wait 2 weeks, no problem. Even 3 ;-).<br>
<br>
Best regards.<br>
<br>

<br>
About a binary open GIS format (see below):<br>
I think the point is to obtain a format with quick random access (shp
file is ok) and with the possibility to edit features (add, modify,
delete) without writing the whole file.<br>
What I like from DXF is that you can use also Curves, and texts. That's
why I mentioned it.<br>
<br>
Another way could be to use SQLite or H2 as local geodatabases.</blockquote>

You can use the H2 spatial extension available here : <a

About TIN, I read about this format because I need an algorithm to
obtain contours from a TIN. ¿Do you know any java code?.</blockquote>

We are developing a TIN generator with hydrological functionalities
(watershed, slope, aspect, contour). Some pieces of code are available
here : <a moz-do-not-send="true"

It's GPL 3.<br>
<br>
Be careful, it's under development. It will be finished in some weeks
maybe 2.<br>

<br>
I had started work on a draft schema for such a format, which you can<br>
learn about here:<br>

BOFF defined a binary format that was meant to serve as an alternate<br>
to Shapefiles. I never followed up on the spec, unfortunately. This is<br>
something I should consider completing...<br>
<br>

<br>
I'm curious what you had in mind when you talk about "enhanced DXF".<br>
I'm a big user of DXF and DWG, so this is a topic I'm interested in. I<br>
will note that the DXF format already supports a lot of entities that<br>
we can't work with in OpenJUMP. Things like text, annotations, basic<br>
blocks, external references, and viewports come to mind.<br>

or some raster<br>

<br>
We're working on an open source library for the creation and<br>
manipulation of TINs right now as part of OpenJUMP's involvement in<br>
Google Summer of Code. Right now were just working on the creation of<br>
TINs from point files (CSV I think), but I know we would be interested<br>
in supporting an "official" TIN format in the future.<br>

Hi all.<br>
<br>
Maybe this is a good place to start some discussions that may continue
in<br>
meetings and hacking events like this:<br>
<a moz-do-not-send="true"
href="http://wiki.osgeo.org/wiki/OSGeo_Hacking_event" target="_blank">http://wiki.osgeo.org/wiki/OSGeo_Hacking_event</a><br>
It could be interesting to define some areas to develop in common, and
see<br>
how they can be useful for every Open Source project.<br>
<br>
For example, some time ago, I read a mail from Frank Warmerdam about the<br>
necessity to define a good geo-format for files. Maybe something
simillar to<br>
.shp, but without its limitations (problems to edit, lack of text
support,<br>
etc). (bxml may be THE solution??)<br>
Or starting with a enhanced DXF, etc. Not only vectorial: to push TIN<br>
formats like this: <a moz-do-not-send="true"
href="http://www.vterrain.org/Implementation/Formats/ITF.html"
target="_blank">http://www.vterrain.org/Implementation/Formats/ITF.html</a><br>
or some raster formats.<br>
<br>
More ideas?<br>
<br>
Cheers.<br>

PS: I think SLD discussion is good and also useful.<br>

PS2: I tryed "reply" to e-mail from Thunderbird and the reply goes to
the<br>
sender, not to the list. Maybe the administrator of the list can change
this<br>
behaviour, to reply to the list by default. (Thanks in advance)<br>

Hi Miguel, all,<br>
<br>
<br>
I've just joined this list, and as a member of gvSIG team, I want to
show<br>
interest for this kind of collaborations.<br>
What other projects are participating in this list?<br>
<br>
<br>
I also subscribed the list as soon as I heard of it. Not exactly sure<br>
what it will be for, but following all the inter-list discussions<br>
between openjump-geotools-andsomeother, I have a good feeling about<br>
it.<br>
I'm member of the JGrass / Udig community.<br>
Cheers,<br>
Andrea<br>
