z-coordinate to given (x,y) coordinate?

[Bernd Welter]

Hello together,

some months ago I've been asked by a customer whether we can offer a function for the following usecase:

• The input data is just a valid x,y-coordinate
• Required output is the z-coordinate aka height above the sea level

Currently we do not provide such a feature within xServers but you can easily access the following API:

http://open.mapquestapi.com/elevation/

Regards from Germany,

By the way: though we do not return the z-Coordinate as requested in the initial post we are able to provide the elevation profile of a route.

Sample track from Bern (CH) to Bolzano (I)

Hi!

Can you tell me how to switch on this height profile?
(To show it on the Map as in your Screenshot)

Thank you!

Hello Julian,

Code: Select all

<ns2:ResultListOptions_4 totalRectangle="false" boundingRectanglesOffset="0" boundingRectanglesC="0"
 tollManoeuvres="false" manoeuvreGroups="false" urbanManoeuvres="false" brunnelManoeuvres="false"
 manoeuvreAttributes="false" segmentAttributes="false" segments="true" dynamicInfo="false" 
 detailLevel="STANDARD" polygon="true" binaryPathDesc="false" nodes="true" texts="true" 
 manoeuvres="true" polygonElevations="true"/>

You have to request both polygon and polygonElevations via the ResultListOptions. This will return the Z-coordinate in the polygon then.

Sample screenshot showing the result list options requesting the z-coordinate in the response.

This also requires the file heights.bin in the maps root folder.

Depending on the framweork you use for the GUI it is then a more or less big challenge to display the diagram.

Best regards,
Bernd
