This looks fantastic, I'll try and merge it as soon as I sort out the 2.3 support |

There was a problem hiding this comment.
Is this file needed? If so it should go to vendor

@florianm I had a look at this and it looks really good, see some comments below:
Also if you can give me permissions to create a dataset on your sandbox site that would be great (user amercader) |
|
@amercader - apologies for the delay and thanks for your feedback! I agree with all your points and will try and implement them, with the only exception being that I need leaflet-draw for the drawing functionality, which in turn requires Leaflet-0.8. I'll probably need some advice around refactoring the code into a snippet later! |
|
This is amazing. Works well on 2.3 as is (merge conflicts notwithstanding). I'm using it with ckanext-scheming, with the relevant display and form snippets @florianm @amercader would love to see this merged (as well as see a PR to ckanext-scheming), let me know if there is any way I can help. |
|
One small issue:
EDIT: Except the umm.. clear button. But I don't know if this was a desired effect? It seems the extent should be cleared between searches. |
|
Denis, Adria, thanks for your feedback, very appreciated! There are some issues with my PR:
I suggest to not merge this PR, but for me to try and re-implement it I would value your input on functional specs - which additional use cases Cheers, On Sat, Jun 13, 2015 at 3:45 AM, Denis Zgonjanin [email protected]

Is there a status update for this. It looks very promising and exactly what we're chasing. Thanks. |
|
@Stephen-Gates we've been using this version in production internally in my Department without problems (setup docs here), but unfortunately I haven't had resources to follow up on this PR. One improvement apart from the suggestions in this thread is to look up geometries by name from an API endpoint, like data.gov.au does (but with polygons) - similar to CKAN's tag autocomplete. |
|
If someone is willing to take this one on and address the issues mentioned on the thread I'd be more than happy to review again and merge if ok. |

Here's an attempt at providing a spatial widget, addressing #91 . There are implications and I'm not sure whether my percussive implementation approach (hitting it with a wrench until it works) was the most graceful way, so I'd be grateful for feedback and suggestions.
Main motivation: My end users love geo-referencing their datasets, and being able to search by map. But many (especially non-GIS-trained staff) struggle with GeoJSON, let alone a GeoJSON geometry. At the same time, my end users have expert knowledge about the true extent of their dataset. This means, letting them draw rather than paste or derive the extent would both make their lives easier (actually, enable them to provide geo-reference at all), and capture the most accurate study extent. Having accurate enough dataset extents would enable an agency to use the search tool to identify possible conflicts of planned field work with existing field sites. E.g., some of my end users manage controlled burns, while others monitor vegetation through 40+ years of non-burning.
So all we need is a map on which we can draw and edit polygons and rectangles, and the map needs to be data-bound to the "spatial" input. Bonus if one could pick spatial extents from a dropdown menu of favourite areas. Even better (haven't solved that one yet) if that list could be maintained through an API and would auto-complete like the tags do.
and, over at ckanext-scheming, there's a new spatial input widget which will be a separate pull request for ckanext-scheming.
Currently, the dropdown comes out of ckanext-scheming, while the map comes from ckanext-spatial. To keep things simple, I've only data-bound map->text, dropdown->text, but neither dropdown->map nor text->map.
Screenshots of working examples are at ckanext-scheming issue 11, but feel free to take my sandbox for a whirl (request a login from me) or, if you need your hands free (depending on how much you enjoy spatial stuff, I'm not judging), watch the thing in action at https://vimeo.com/116324887
