Changeset 512 in josm for trunk

Timestamp:

2008-01-04T01:25:43+01:00 (16 years ago)

Author:

Message:

Add support for two non-standard GPX variants:

• <link>URL</link> (gets silently translated to <link href="URL"/>)
• <... lat="nan" lon="nan"> (we parse "nan" as Double.NaN and skip these points when rendering)

Location:

Files:

• gui/layer/GpxLayer.java (modified) (1 diff)
• io/GpxReader.java (modified) (5 diffs)
