Is this a bug of pycoast 0.5.2?

[張伯誠]

Hello,

See the attached images, the area definition of lon_0_lat_0.png is:

REGION:equirectangular{

NAME:eqc

PCS_ID:eqc

PCS_DEF: proj=eqc, lat_0=0.0, lon_0=0.0 

XSIZE:2048

YSIZE:1024

AREA_EXTENT:(-20037508.342789244,-10018754.171394622,20037508.342789244,10018754.171394622)

};

the other is lat_0=0.0, lon_0=180.0, the remaining is the same.

lon_0_lat_0.png is nice but lon_180_lat_0.png has many useless horizontal lines. 

If you take a closer look at it, you would find that the lines come from the border of South Africa.

Is it a bug of pycoast 0.5.2? 

I think pycoast does not handle such situation, 

e.g., half continent is in the right side while the other part is in the left side.

You are right.
Coastlines need a consistency check
that drawn line-segments do not exceed some sort
of threshold. We had considered that, but now
I think I should add that improvement.

Cheers,
Hrob.
