Where is the GPX Path?

Where is the GPX Path?

(well the answer is on the map now thanks to Bill Chadwick's update of GPX import.)

South West Coastal Path - Lizard Point (Cornwall)
Importing of GPX data is very fast and when in 3D (Earth) Mode it shows you the terrain your likely to encounter. (weather not included!)

"GPX to GeoJson Converter is purely a convenience for those who want to read a random GPX url on a page from a host that lacks server side scripting"

Example - The South Coastal Path

NOTE* The most annoying issue for this site is not the author's fault at all. It's the Ordnance Survey with ridiculously low openspace tile quota (currently 30,000 per 24hrs).
This is a very popular site and 30,000 tile impressions needs to be 75,000 at least.
Why does the Ordnance Survey insist of bottlenecking useful web mapping applications?
And why allow users to have 1:50,00 colour rasters (Landranger Maps) and StreetView 1:10,000 and not the very useful 1:25,000 (Explorer Maps)?

Data for the South West Coastal Path is available from (GPX format for GPS)

Where is the Path? - 3D

A recent update which includes the option of 'Earth' (Google Earth inside the web browser)



Allows the user to create a route of their choice and view it in 3D - attribution of the points is available.
Export to GPX for input into a GPS device.
*Earth plugin must be installed to view the content.
In the drop down list select OS+Earth

There is a limit on the number of Ordnance Survey tiles per a 24 hour period (30,000 tiles) - keep an eye on the percentage bar in the bottom left corner.
OS please raise this limit to 50k or higher.

Full credit goes to Bill Chadwick for producing this nifty side-by-side mapping application.

Yahoo! Internet Location Platform (New Geocoder)

Yahoo! Internet Location Platform (New Geocoder) New!

"The Yahoo! Internet Location Platform provides a resource for managing all geo-permanent named places on Earth. The purpose in creating the Internet Location Platform is to provide the Yahoo! Geographic Developer Community with the vocabulary and grammar to describe the world's geography in an unequivocal, permanent, and language-neutral manner.

The Internet Location Platform is designed to facilitate spatial interoperability and geographic discovery; users can traverse the spatial hierarchy, identify the geography relevant to their users and their business, and in turn, unambiguously geotag, geotarget, and geolocate data across the Web."

Basically this is a Geocoder for Places across the World. The accuracy is fairly precise and the easy to understand.

Here is an example:
http://where.yahooapis.com/v1/places.q('10%20downing%20street%20london%20uk')

and also you can geocode UK Postcodes - full UK Postcodes!

http://where.yahooapis.com/v1/places.q('SW1A2AA')

Yahoo Where Geocoder
Centroid is the postcode centre. So 51.503201, -0.12617

Rate Limits
Currently, users of the Internet Location Platform are limited to 50k queries per day.

Terms of Use (Please check this if you intend using this service with other non Yahoo Applications)

Geeky Stuff

"In simple terms, the Service allows you to look up the unique identifier - called the Where on Earth ID, or WOEID - for almost any named place on the Earth; it also allows you to resolve a WOEID you have received from a third party - such as Fire Eagleā„¢ or Upcoming - to the place it represents.

The API is accessed via HTTP GET; the following examples can be cut-and-paste into a web browser to view the results:"
