Re: [JPP-Devel] ESRI file geodatabases

2011-08-08 Thread Sunburned Surveyor

It looks like there is some interest and opportunity for collaboration
with the GeoTools team on FGDB support. You can see the thread I
started on their development mailing list here:

http://osgeo-org.1803224.n2.nabble.com/FGDB-Support-in-GeoTools-td6662165.html

I'm already way over committed, so I can't take the lead on this
effort, but I hope we can work together with the GeoTools people if
there is a desire and resources for work on a FGDB library.

completely tailored to support ESRI's needs, rather than a more general set
of needs.

It would be GREAT to have a truly open geospatial format, which was

It would be great to have a solution for accessing FGDBs from Java
(OpenJUMP of course, but I'd also like to be able to read them from JEQL).
If OJ could read them that should make it quite appealing for working with
newer ESRI data.

One possiblity is this work on a Java interface to the FGDB API. If this
project has taken care of all the JNI nastiness, then it could be worth
using.

I know that the GDAL project is working on adding a driver for the FGDB

Obviously there is interest in geotools to add a gt2 datastore for it. Also
cite:

Justin Deoliveira: Just a note that fgdb support was recently added to ogr as
a format... so using the existing ogr datastore (and its java bindings for
ogr) could be an easier route to go. However it requires ogr = 1.9.0.

In any way we should (re)implement a geotools reader/writer extension or pimp
my old GT2 reader/writer to work with the latest oj.

Hey folks,

  Does anyone know how to find the shortest path between 2 nodes on

Re: [JPP-Devel] ESRI file geodatabases

2011-08-08 Thread Larry Becker

It looks like there could be cooperation between the two groups on the
development of the Java interface at least.

The following thread is a bit discouraging toward that effort:
http://forums.arcgis.com/threads/35051-Problem-loading-libraries-to-Java

The sourceforge project at
http://sourceforge.net/projects/jfilegdbexplore/looks very thin, but
seems to imply it can be done.

The post at
http://forums.arcgis.com/threads/2696-How-To-File-Geodatabase-using-Java is
listed under the ArcObjects forum, and not the forum dedicated to the new
API.

The ogr support approach would not seem to provide any advantage beyond
translating FGDB to shapefiles as SkyJUMP uses that library for mdb
translation now.  There may be Java bindings for the low level API in OGR
that I'm not aware of, but this would be a level removed from the actual API
we want to use.

The only way this would be any use in JUMP (IMHO) is if we could open and
edit FGDBs like ArcMap does.  We discussed the idea of supporting the Access
personal geodatabase years ago, but abandoned the idea because it was too
risky because it was proprietary and had no published API.

As far as the ESRI license, it would put us in the same position as having
the end user download the MRSID executable.  Not good, but doable.

On the minus side, by supporting the proprietary FGDB format, we might be
using effort that could be better applied to open source solutions.

What are the viable open source alternatives?  Spatial Lite seems to have a
C API as well.

just a few thoughts,

Larry

 Hei Guys,
 
 here two things with request for your opinions:
 a - I noticed that Sourceforge offers now Wordpress for blog writing. I 
 requested activation of this feature. Hence we can start writing blog entries 
 on OpenJUMP such as  small tutorial, tips  tricks, and maybe new version 
 releases... but I am not sure about the latter. I have been waiting for this

while it's not very beautiful i am satisfied with the wiki. we are already 
pretty much spread over several platforms namely website, wiki, mailing list 
and not to name the forums and trackers on sf.net.
a new cms would only contribute to this scattering. the wiki is already 
outdated in some areas and i'd rather see it updated than to start a fresh with 
a new cms.

btw. don't expect to much from sf.net wordpress. last time i checked you were 
not even able to change the theme. what are your reasons to fancy wordpress? 
i'd see a possibility to convert the website over to wordpress, adopting the 
style and such. but therefor we'd have to install ourselves a wordpress. i 
could lend some webspace for that, as i think th sf.net webspace would not 
suffice, but i could be wrong.

so as a website replacement i think it is a good idea.

 
 b - I also noticed that via Sourceforge and creation of PayPal account we can 
 activate a donate-Button on SourceForge. All Admins (Landon, Ede, Michael  
 I need to approve the feature on SF before it can be activated.) I guess we 
 should all read more about it first:
 http://sourceforge.net/project/admin/donations.php?group_id=118054
 But I like to have know how you think about donations via SF or more 
 precisely: should we look into it or keep things as is. I am actually asking 
 here all on the email list who have an opinion about that.

is there a possibility to share paypal accounts, so several people would have 
access and could control each other? generally i am in favor, we should at ave 
the possibility for people to donate. if nobody donates, then at least it's not 
because there is no possibility.

 
 PS: we still have these incredible download rates (2000 a month for OJ 
 itself) - see the attached pdf. But I am not sure why people would download a 
 lot on Monday... doesn't make sense to me. Btw. one can also see that for 4th 
 of July (national US holiday) the download rate was a bit lower.
 
 

maybe we should setup a hello there, please tell us what you think of 
openjump in oj that pops up after the first start or first 30 days. we could 
route users from there to a page where they could input a message or even hints 
what could be better. currently we have no f*** clue who is using us, except 
that we are used, i guess ;)

Hi ede,

why would it be removed?

I was referring to the OGR API adding a level of abstraction above the
actual FGDB C++ API, but still being not a Java API.

i still like the idea of having an interface that uses geotools mechanisms
to load data. that would automatically enable oj users to use all gt2
datastores. opinions?

I like using geotools too.  If they implement a FGDB datastore that has read
and write access, it should be the preferred method.

Cooperation with GeoTools seems like a reasonable way to go.


The ogr support approach would not seem to provide any advantage 
beyond translating FGDB to shapefiles as SkyJUMP uses that library for 
mdb translation now.  There may be Java bindings for the low level API 
in OGR that I'm not aware of, but this would be a level removed from 
the actual API we want to use.
Agreed.  It's bad enough having to include the C libs needed for access 
to non-Java APIs, but including a bunch of OGR libs as well just 
compounds the problem.


Also, from a development point-of-view if there are issues that makes 
two places which need to be looked at and updated - and if the problem 
is in OGR then OJ is hostage to OGR's schedule.


The only way this would be any use in JUMP (IMHO) is if we could open 
and edit FGDBs like ArcMap does.  We discussed the idea of supporting 
the Access personal geodatabase years ago, but abandoned the idea 
because it was too risky because it was proprietary and had no 
published API.


Disagreed.  Providing Read-Only access to FGDB is still very useful, 
since it provides a gateway into OJ for ESRI users.  And there is lots 
of functionality which is difficult to accomplish in ESRI tools which is 
easy in OJ (and other Java solutions like JEQL). I'm now in the 
unenviable position of working with ESRI tools on a daily basis, and by 
the biggest stumbling block to trying to introduce OJ into my 
environment is the inability to read the (sometimes huge) FGDBs that we use.


Another way to think of this - what better way to to suck the life out 
of a proprietary format than to make a one-way gateway into an open 
solution?  (This is a tried-and-true ploy of proprietary platforms...)


I'm not even sure that the ESRI FGDB API supports writing.. or at least, 
not without a lot of caveats.


As far as the ESRI license, it would put us in the same position as 
having the end user download the MRSID executable.  Not good, but doable.


On the minus side, by supporting the proprietary FGDB format, we might 
be using effort that could be better applied to open source solutions.

See comment above about providing a gateway...


What are the viable open source alternatives?  Spatial Lite seems to 
have a C API as well.
SpatialLite support would be useful too, but I don't think it's going to 
replace FGDB in the wider world anytime soon (unfortunately).


just a few thoughts,

Larry
