elevation profile using QT/QML

[TASL_Virendra]

Hi

I want to create elevation profile using QT/QML SDK , as available in java or arcgis pro. Can any one suggest how I can do that. 

Even suggestion how to plot a graph would be nice.

Thanks

Hi @TASL_Virendra, we are looking into the best solution to achieve this and will get back to you soon.

Hi @TASL_Virendra.

You can calculate the elevation at a single point using the Surface::locationToElevation method. An example of this method being used can be found in the Get Elevation At Point sample. The Surface::locationToElevation method can be called repeatedly for all locations along a line to calculate an elevation profile.

A suggested workflow to create an elevation profile would be as follows:

• Draw/create a profile line in the scene view.
• Densify the line to add additional points along the profile (see GeometryEngine::Densify).
• For each point along the line, query the elevation using the Surface::locationToElevation method.
• Once all elevation queries have completed, display the collection of heights using a 3rd party graphing library (e.g. QCharts).

Let us know if you have any further questions.

Hi Andrew,

Thanks for such details work flow, we are able to draw a elevation profile as required.
