Geoar 0.2.0 - More GIS & Laszlo !

[macco]

Hi !
People, there is a new version of Geoar.
Now there are some improvements specially on RIAs aspect (for instance tooltips, new validators and i18e). I use some codes and ideas from thread in forums and make a mixture (for instance, tooltips are internationalized, better...all the application is internationalized and the mechanism to do it is really really easy to use and learn).
I have done a version on "latin" languages (10 languages from where you can choose) and a particular version for arabian/spanish (since i dont want to include too much fonts on the application).
- i tried to create a japanese and chinese version too, but it's a little more complex since fonts (ttf) are special, but i'll continue that task !- maybe next release-

Take a look at

http://geoar.sourceforge.net

on demo section you will see some examples working (consider that geoar is using an external map server, and sometimes it's really busy - and frustrating to get the map download).

well...that's all folks
See you soon

José

Special thanks to:
- Togawa (i use part of his excelent code for validators and tooltips, improving them and adding new features as i18e, you are a genius !).
- Antun (from who i learnt and take ideas to improve code)

Hello, macco!

Congratulations for your work!

As far as I could understand geoar is only for raster (bitmap) format. How about integrating a vectorial format (svg or something else) in openlaszlo? Were you successful on that? I've been searching in the forums and found svgview, but no way to interact (user clicks on a map polygon and a lzx function is activated).

Any insights or tips are welcome.

Thanks.

lchaves..how are you ?
Thanks for being interested on this development. :-)

Geoar implements WMS access, so you will get "Images" from request to the Map Server you use.
Now we are working on WFS implementation (that means not to get an image from Servers response, instead of that we will receive an XML file that we would map to a vector layer).

Laszlo offers a nice and easy to use view where to draw lines and points, so i guess that this type of features is what you are expecting to be implemented. dont you ?

I'll look for that SVGview you mentioned, cause i'm sure that it would be useful (some map servers - like Geoserver - implements outputs on SVG format, so it would be a nice feature to include on our project).

I dont know if you have checked our site: http://www.geoar.com.ar, there i have uploaded new demos from version 0.5.

Example: http://www.tsavogroup.com.ar/sites/geoar/demos/demo3/

We have integrated GoogleMaps, add new tools and behaviour, we redesign all the structure (cause the first version was nice to solve our "work" needs, but in terms of OO design it was terrible. Too much to do: learning Laszlo, learning about Maps, WMS, WFS, etc and also implementing something that works !!!.....it was a nice experience. In that moment i have other interests...- make it working -).

Now we have more chances to make it better, so ....we have a really improved design (to add "points" as googlemap does it's really simple - just to declare an xml).

Well....be patience, we are working on that vectorized layers. Please if you have some info that could be useful, let me know about that.

Best wishes
Jose

Hello, Macco,

Drawing lines and points for a specific map is ok, although it's a painful work to do. What I wanted is something more general, like an SVG renderer, but one that would allow the user interaction with each polygon/path.

Thanks for sharing your experience. I'm working on an academic work where I'm comparing severla RIA technologies (Flex, Openlaszlo and GWT) for GIS. Whenever I have this work done I'll post here in these forums.

Best for you.

Hi Macco,

Very impressive, especially the image tiling, which I presume is done in the classes wmsmapvisor.lzx and hashtable.lzx. Is it possible to make those sources available?

We have a mapping application which has a wms base map and overlays from web service in plain xml format (we tried wfs but found it very slow to parse because of the deep loops in the structure). Please have a look: http://magma.geonet.org.nz/maps/summary.html

Thanks

Is there a timeframe when you expect to release 0.5 of Geoar? I'm currently using a static image and calculations to plot points from a tuturial found here (http://staff.osuosl.org/~peter/) and was looking to upgrade to WMS solution.

Thanks,
Tony

There is a new version of Geoar available on sourceforge. Please visit www.geoar.com.ar and you will be redirected to downloads, news and demos.

(i have changed server so i'm working on making everything working...:-)...specially demos, that use the proxy.php file, but you can access source code at sourceforge. good programming !)

Best wishes
