Supported gpx namespace are:
1. http://www.topografix.com/GPX/1/0
1. http://www.topografix.com/GPX/1/1
1. http://www.garmin.com/xmlschemas/GpxExtensions/v3
== Installation ==
1. Use the classic wordpress plugin installer or copy the plugins folder to the `/wp-content/plugins/` directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Add the shortcode [sgpx gpx="&gt;relative path to your gpx&lt;"]
== Frequently Asked Questions ==
= what are all available shortcode attributes? =
The attributes are:
1. gpx: relative path to gpx
1. width: width in pixels
1. mheight: map height
1. gheight: graph height
1. mtype: map aviable types are: HYBRID, ROADMAP, SATELLITE, TERRAIN
shortcode with all the attributes : [sgpx gpx="&gt;relative path to your gpx&lt;" width=100% mheight=300px gheight=200px mtype=SATELLITE]
= What happening if I've a very large gpx? =
This plugin will print a small amout of points to to speedup javascript and pageload.
= Is it free? =
Yes!
