kartograph未知形狀類型（25）

我試圖用kartograph PY如下生成一個SVG地圖：kartograph未知形狀類型（25）

from kartograph import Kartograph 
K = Kartograph() 
config ={"layers": {"mylayer": {"src": "42MEE250GC_SIR.shp"}} } 
K.generate(config, outfile='mymap.svg')

而且我得到這個錯誤：

Traceback (most recent call last): 
    File "<stdin>", line 1, in <module> 
    File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\k

    _map = Map(opts, self.layerCache, format=format) 
    File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\m

    me.proj = me._init_projection() 
    File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\m

    File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\m

    geom = shape2geometry(shp, ignore_holes=ignore_holes, min_area=min_area, bbo 
x=bbox, proj=self.proj) 
    File "c:\python27\lib\site-packages\kartograph.py-0.6.8-py2.7.egg\kartograph\l

    raise KartographError('unknown shape type (%d)' % shp.shapeType) 
kartograph.errors.KartographError: ←[0;31;40mKartograph-Error:←[0m unknown shape 
type (25)

查看源Kartograph的代碼我們有這個：

if shp.shapeType in (5, 15): # multi-polygon 
     geom = shape2polygon(shp, ignore_holes=ignore_holes, min_area=min_area) 
    elif shp.shapeType == 3: # line 
     geom = points2line(shp) 
    else: 
     raise KartographError('unknown shape type (%d) in shapefile %s' % (shp.shapeType, self.shpSrc)) 
    return geom

有人可以幫助我嗎？

我在下面嘗試了這個，我得到了另一個錯誤。

if shp.shapeType == 25: 
    return None

錯誤：

未生成mymap.svg – luckasx

我的錯誤，我的意思是什麼輸入文件？ –

輸入文件是從這裏獲得的巴西國家地圖：ftp://geoftp.ibge.gov.br/malhas_digitais/municipio_2010/sc.zip – luckasx

我找到了解決辦法是改變的源代碼添加此：

if shp.shapeType == 25: 
    geom = points2line(shp)

我敢肯定，這是不是最好的解決方案，但它解決了我問題
