Hey guys,

How can I search by a shape from OLE editor? It is possible to do it?
So I draw a shape with a tool then use this layer in the search function.


Thanks!

Unfortunately not (yet). Searching in a target Vector Layer from
geometries in a Source Vector Layer (SearchByObjectSelection via
Heron.widgets.search.SearchByFeaturePanel) is currently only available
when the Source Vector Layer is a WFS (related to a WMS).

With SearchByDraw which you probably know:
http://lib.heron-mc.org/heron/latest/examples/searchbydraw/ you can draw
several kinds of geometries.

A possible solution would be to add an option to the
Heron.widgets.search.SearchByDrawPanel to use geometries from the
Drawing Vector Layer as the SelectionLayer or via the
SearchByFeaturePanel to use features (all?) from the Drawing Layer.

best,

Just

Hi, belazs. 
I have made a custom widget to perform a search by vector layers (including ole editor, uploaded features and custom layers) that is very useful to me. You can see it working here


1)Draw something
2)Go to searches->"busqueda por buffer"
3)Select editor from vector layers
4)Press "buffer"
5)Select "Descarga_cartas_ign" (a very light shape)
6)Press "busqueda"

If it works for you, i can help you.

Hi Mauro,

These are really impressive (and working) extensions for Heron Vector
Search!
I would love to see these integrated in Heron and Heron-examples:
i.e. Heron.widgets.search.SearchByBuffer and possibly others like
StreetView.

Are you prepared to donate the code to the project, maybe even via a
Pull request in GitHub?

best,

Just

Of course i would donate the code (it would be not much a donation, most of the code is yours). 
Let me see if i can build a working example (maybe based on the search by feature selection) and perhaps i will ask for a little help for the github part.

Ok, i have this to begin with:


it is based on the google example because i needed a projected (in meters) SRS
Also, it uses some libraries with their own licences (jsts->gnu, javascript.util->MIT, and attache.array->copyrighted?). 
These are not available from http://cdnjs.cloudflare.com, so maybe i need to find another source

Any suggestions?

Hi,

Many thanks Mauro: your additions/example for SearchByBuffer via GitHub
have been integrated in Heron.

All: see the working example here:

http://lib.heron-mc.org/heron/latest/examples/searchbybuffer

The licenses should not be a problem, e.g. OpenLayers is BSD, I see that
JSTS is in CDNJS now.

I made two small changes to your example code:
- renamed class SearchByBufferPanel + hr_searchbybufferpanel
- moved SearchByBufferPanel.js to the Heron source dir and integrated in
builds so it is available in Heron.js and thus next 1.0.7 release.

We always welcome these kinds of, or any, contributions. This is one of
the things that makes Open Source work!

best,

Just

Hi Xuan! The code for my project is in github, my user is "el486" and the project is "heron-dipsoh".
My site is based on heron 1.0.5,  if you use v1.0.7 some mods i use are not necessary
Let me know if you need any help with the setup!
