Failing to create a map when using filters

[dunamos]

Hi,

First of all, sorry for the surely non-accurate informations, I am not used to Python.

I followed the doc in order to create the .svg map in need ( a map with only France, Italy, Spain and Portugal), but, whenever I want to use filters ( in order to keep only the countries I need), the map creation fail.

Here is my .json file :

{
    "layers": [{
        "id": "FTC",
        "src": "ne_50m_admin_0_countries.shp",
        "filter": { "ISO": ["FRA", "ITA", "ESP", "PRT"] }
     }]
}

And here is what the terminal is giving :

cli.py, in render_map()
  71: K.generate(cfg, args.output, preview=args.preview, format=format, stylesheet=css)  kartograph.py, in generate()
  46: _map = Map(opts, self.layerCache, format=format)  map.py, in __init__()
  48: me.proj = me._init_projection()  map.py, in _init_projection()
  88: map_center = self.__get_map_center()  map.py, in __get_map_center()
  140: features = self._get_bounding_geometry()  map.py, in _get_bounding_geometry()
  257: charset=layer.options['charset']  layersource/shplayer.py, in get_features()
  96: if filter is None or filter(drec):  map.py, in <lambda>()
  252: filter = lambda rec: layerFilter(rec) and boundsFilter(rec)  map.py, in <lambda>()
  239: layerFilter = lambda rec: filter_record(layer.options['filter'], rec)  filter.py, in filter_record()
  23: res = res and filter_record([key, 'in', filt[key]], record)  filter.py, in filter_record()
  27: res = filter_single(filt, record)  filter.py, in filter_single()
  35: prop = record[key]

I can create a map when I am not using filters, but it gives me a full map of the world...

I'm using Ubuntu, and I followed the installing to the letter.

Thanks in advance for you help,
Regards.

A temporary solution, waiting for developers to fix this bug, is to use the filters inside the Python script, as I already described here: http://stackoverflow.com/a/22793960/320369

Cheers,

Ric.

I am really sorry to add an other question to this thread, specially because it is not really in the subject, but, I can't remove the little islands, even using the "bounds" thing... It is the last time I ask for help.

Thanks in advance !

Sorry, but I did not try that option yet.
Try to ask on Stackoverflow, maybe somebody could answer that question.

Best regards

I followed your advice rmnianchi, for those who might be interested, the stackoverflow thread is here : http://stackoverflow.com/questions/23659073/cant-remove-the-little-island-when-creating-a-svg-map-with-kartograph-py

Regards.

[rmbianchi]

Thanks for the link!

I also saw your post on gis.stackexange. Very useful! I hope you'll get an answer. It could also be useful to me for one of my project where I use France and where I would like to separate French Guyana from European France territory.

Best regards,

Ric.

If anyone else is having this issue with the "ne_50m_admin_0_countries.shp" shape-file from Natural Earth, a quick fix that worked for me is using "iso_a3" as the key for the filter (as opposed to "ISO").

(Also, it appears the keys are not standard across NE files, that works in the 50m file but not the 10m one).
