Add a gpx track with altitude graph
Draws a gpx track with altitude graph
== Description ==
This plugin has, as input, the GPX file with the track you've made. As output it shows the map of the track, fixed with an altitude graph.
- Also working on iphone/ipad/ipod
- iphone/ipad/ipod Compatible
Try this plugin on <a href="http://www.pedemontanadelgrappa.it/category/mappe/">http://www.pedemontanadelgrappa.it/category/mappe/</a>
Thanks to: <a href="http://www.securcube.net/">www.securcube.net</a>, <a href="http://www.darwinner.it/">www.darwinner.it</a>, <a href="http://www.pedemontanadelgrappa.it/">www.pedemontanadelgrappa.it</a>,
<a href="http://www.darwinner.it/featured/wp-gpx-maps/">Bugs, problems, thanks and anything else here!</a>
== 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!
== Screenshots ==
1. Screenshot Sample
2. Screenshot Admin area
== Changelog ==
= 1.0.3 =
* Added Settings link on plugins list
* Added attributes width, mheight, gheight, mtype on shortcode.
= 1.0.2 =
* You can manage your gpx files in the admin area.
