I have a voxel layer (from netCDF file) in local scene. I want to query the data value of the voxel layer by a give coordinate (x,y,z). I check the arcgis pro SDK and found that I access the voxellayer and voxelvome and the statistics of the data value such as maxvalue and minvalue:
//Get the first voxel layer in the TOC
voxelLayer = MapView.Active.Map.GetLayersAsFlattenedList().OfType<VoxelLayer>().FirstOrDefault();
if (voxelLayer == null)
return;
QueuedTask.Run(() => {
//access the volume
var volume = voxelLayer.SelectedVariableProfile;
var vol_size = volume.GetVolumeSize(); //(double X, double Y, double Z)
//TODO - use the dimensions
//vol_size.X, vol_size.Y, vol_size.Z
...
and also can get the statistics of the data value by:/var voxelLayer = ... ;
//Must be on the QueuedTask.Run()
//get the selected variable profile
var variable = voxelLayer.SelectedVariableProfile;
//Must be continuous to have a stretch renderer
if (variable.DataType != VoxelVariableDataType.Continuous)
return;
var renderer = variable.Renderer as CIMVoxelStretchRenderer;
var color_min = renderer.ColorRangeMin;
var color_max = renderer.ColorRangeMax;
//increase color range by 10% of the current difference
var dif = (color_max - color_min) * 0.05;
color_min -= dif;
color_max += dif;
//make sure we our color range does not exceed the current
//renderer data range
if (color_min < variable.GetVariableStatistics().MinimumValue)
color_min = variable.GetVariableStatistics().MinimumValue;
if (color_max > variable.GetVariableStatistics().MaximumValue)
color_max = variable.GetVariableStatistics().MaximumValue;
but I can not find a way to get the exact data value for a given coordinats (x,y,z)?
Anybody can kind help me?
Thanks!
