KML Altitude Filler (v2.1)

If you have plain tabular data you wish to work with, try this page from gpsvisualizer.com

Please select the KML file you would like to add alitude for, subject to the following restrictions*:

KML File:

WebService to use:
geonames.org SRTM3 (Worldwide: SRTM data, 90m grid spacing)
geonames.org GTOPO30 (Worldwide: GTOPO30 data, 1km grid spacing)
earthtools.org (US & Europe: SRTM data, 90m grid spacing)
gisdata.usgs.net (Worldwide, various spacing)

'Zero' Altitude to replace:
(use if you have a constant alititude to replace)

Takens on average 2 seconds per point (deliberatly slowed down!), so please be patient, and only click the Send button once.

* However with enough interest will consider lifting any of these restrictions, but might add output as KMZ to save bandwidth, but that will be transparent to you, the end user.

*** It works for me but your mileage may vary! Use at your own risk, no guarantee is offered. ***
