gHowl Elevation Service

Demonstration of the upcoming Elevation Service component. The input to this component will be a set of WSG84 coordinates. The component queries the Google Elevation API and returns the coordinate's Elevation. Note, this is quite low resolution (like what you find in Google Earth) and often times does not serve as an accurate representation of the actual Elevation. There are holes in the data, and thus at times the data is interpolated. Nonetheless, for a quick understanding of the site terrain, it can be a helpful tool.

Comment by Jay Stevens on November 20, 2012 at 7:33am: Hi Luis,

I'm having the same issue as Lei-jie ZHOU, but I am already using the correct order, inputting {-111.502387,40.609654,0} for the EAP_Geo coordinates and I am connected to the internet. The XYZ to GEO component is passing on data to the Get Elevation component, but this is where it gets hung up...Get Elevation is outputting "empty number parameter"...please let me know if you have any ideas. Thanks Luis!

Comment by Luis Fraguada on February 26, 2012 at 3:39am: No prob! I should prob change that around. It seems people are used to thinking in 'Latitude' then 'Longitude' but somehow it was nicer to have it the other way around for the code and mapping to xyz...

Comment by Lei-jie ZHOU on February 26, 2012 at 3:37am: fatastic! Thank you Luis!

Comment by Luis Fraguada on February 26, 2012 at 3:20am: Ok, switch the latitude and longitude...

try {120.444432,28.214854,0}

Comment by Lei-jie ZHOU on February 26, 2012 at 3:09am: yes, I am sure I connect the internet. my location is {28.214854,120.444432,0}. I try it

several times, but it can don't work.

Comment by Luis Fraguada on February 26, 2012 at 2:33am: Are you connected to the internet while running the definition?

Comment by Lei-jie ZHOU on February 26, 2012 at 2:30am: It has a problem trying to use different location.

Comment by Nay Soe on October 7, 2011 at 2:01am: Having a problem trying to use different Longitude, Latitude, Altitude for this script. such as this {40.809262,-96.616173,0} one. Is there anything else i need to change other than inputting these points in the XYZ to Geo component?

Comment by Luis Fraguada on September 17, 2011 at 4:03am: This was released with gHowl_r50. You can download it by visiting the gHowl group. Try it out and let me know if you have any issues.
