[JPP-Devel] Request informations about OpenJUMP Google Summer of Code 2008
Hi all, I would like to have some informations about the status of the OpenJUMP projects connected to Google Summer of Code 2008. As far as I remember there were: 1) JTIN, 2) Port of SEXTANTE to OpenJUMP. Is it correct? Thanks in advance. Peppe __ Do You Yahoo!? Poco spazio e tanto spam? Yahoo!

Re: [JPP-Devel] Request informations about OpenJUMP Google Summer of Code 2008
very short answer from Germany (i am traveling): JTIN (i.e. Christopher) has all code checked it at the SVN... but I have not found the time to test it. There is no separate Extensions.. so it right now only accessible for programmers (and one needs Java3d classes, which I haven't installed yet) I am not sure if Leandro send the code... I think he hasn't check it in neither.

Re: [JPP-Devel] Request informations about OpenJUMP Google Summer of Code 2008
The code for Christopher's JTin project is in the SVN. Christopher and I have talked, and I believe he will stay involved with OpenJUMP even though his summer project is completed. I hope he will do more work with JTin, or at least hang out to answer some of my questions. :] I also hope to do some work with JTin. Christopher and I talked about constructing a TIN that utilizes boundaries, holes, and breaklines. This makes the construction of the TIN a little more tricky than one built from just points. I'm still attempting to chew on an alogrithm or series of algorithms that can do the trick. This will be the first task I tackle when I have time to start working with JTin. I'm not sure if Leandro's stuff ended up in the SVN, but I seem to remember him stating in an e-mail that he would continue his work on the project. I copied him on this e-mail so he can tell us where he left things. I've been meaning to do a summary of this Summer-of-Code, and to request feedback from those involved, but I haven't had time yet. I'll try to do it tonight right after work. The Sunburned Surveyor On Thu, Sep 18, 2008 at 1:19 PM, Nacho Uve <[EMAIL PROTECTED]> wrote: > >> 2) Port of SEXTANTE to OpenJUMP.

[JPP-Devel] Questions about GML 2
I'm doing some work converting GPX files into "waypoint observations" stored in GML 2. I want to be able to read the GML 2 files into OpenJUMP. I had a couple of questions that I thought you guys could help with: [1] I'm trying to figure out what the "header" of a GML 2 file should look like. I'll be buggered if I can't find a good GML 2 sample file on the web. Is this what a GM you2 file should look like?: Some Attribute Value Some Other Attribute Value [2] I know that OpenJUMP currently requires the use of an input template to read GML. I was wondering if it might be possible to automatically determine the attribute data type (String/Date/Integer/Double) automatically based on the first attribute values encountered in the file. This would eliminate the need for an input template and would make it easier to import GML 2 files. Any thoughts on this?

Re: [JPP-Devel] Questions about GML 2
Ideally GML documents should include a schema definition using xsi:schemaLocation but they rarely do. If they did you could use the XML parser to find that location and then parse the schema (not an easy task) and then map it automatically to a FeatureSchema. Again not an easy task as GML is hierarchical and JUMP is not. Have a look at the spec there are some examples in there. http://www.opengeospatial.org/standards/gml A GML document contains a single feature, which typically will be a feature collection (feature collections are features). http://www.opengis.net/examples"; xmlns:gml="http://www.opengis.net/gml"; xmlns:xlink="http://www.w3.org/1999/xlink"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://www.opengis.net/examples city.xsd"> Cambridge http://www.opengis.net/gml/srs/epsg.xml#4326";> 0.00.0 100.0100.0 The river that runs through Cambridge.

Re: [JPP-Devel] Questions about GML 2
I second Paul's idea about looking at the spec for examples. You need more gunk than is in your example - welcome to the wonderful world of XML... As for auto-determining input data types, there's two reasons we choose to provide a template containing this and other information - if the input file is empty you still need to know the datatype in order to create a layer - the template made it easier to specify exactly which elements contained attribute values. You could certainly write code that "guessed" the information contained in the template. In the end internally you'd end up creating a data structure which contains exactly the information in the template. We just didn't take the coding this one step further, due to lack of time and use cases. I agree that the template is a bit complicated - but at least it lets you parse a GML file. You can probably find other tools which does this for you a bit more automatically (OGR maybe?). At the time we wrote this code none of these were available.

If they did you could use the XML parser to find that location and then parse the schema (not an easy task) and then map it automatically to a FeatureSchema. Again not an easy task as GML is hierarchical and JUMP is not." The standard XML schema is a real pain-in-the-rear, and I have no plans on using them or parsing them. I'd using an alternative schema language first. At any rate, I don't think I'll need schema at this point. Paul wrote: "Have a look at the spec there are some examples in there." I've been reading the standard for GML 2.0. They have plenty of examples on how to code features with geometry, features without geometry, and just geometry. I've got a handle on this part. I was more interested in determining if a root element existed. It doesn't appear from the example that you provided that one does. I'll poke around in my GML 3.0 book and on the OsGeo mailing list to see if I can confirm this. Paul wrote: "You'll also need to learn about namespaces." I think my needs are more simple than this, so I will try to avoid namespaces if I can. Paul wrote: "I found the JUMP templating code for GML confusing and never really had much luck with it." I agree. Jon Aquino walked me trough the process of creating an input template once, but it was a long time ago. Paul wrote: "Your best bet is to find some tool to convert from GML into a simpler format." Perhaps. I've always thought GML 2 was an unappreciated gem. It is a simple, human-readable, and computer-parsable format for the transfer of simple feature data. I always thought it could have been more successful with the correct (FOSS) tools and some better documentation. Thanks for your quick response Paul.

Understood. I actually thought about an "empty" GML file. I think I can throw the user a warning message and abort the file import if I encounter this situation. Martin wrote: "You could certainly write code that "guessed" the information contained in the template.

I'm actually writing my own tool. It looks like I have two (2) options to proceed with. I can think about a much simpler input template. Something like this: Attribute Name Attribute DataType numberOfLanesinteger surfaceType String dateConstructed Date Or, I can automatically determine the attribute data type for non-empty files. I'm actually dealing with a GML 2 file whose content I already know, so I could write a special parser that already knows what attributes to expect. However, I thought it might benefit others if I could improve a more generic GML 2 parser. Thanks for your comments Martin.
