Been struggling with this for a couple of days now and could use a fresh set of eyes on the problem. I'm trying to get an elevation spot value for a DEM file. When I inspect any point with the Information Tool I get a pixel value of elevation. However when I try tp pull the value using arcpy.management.GetCellValue() I always get a NoData.
This is pretty generic code that was pulled form Google searches, it reports the X and Y correctly just not the pixel value.
Any help would be appreciated
Thanks

Code:
class ToolClass10(object):
"""Implementation for MapSARElevation_addin.tool_1 (Tool)"""
def __init__(self):
self.enabled = True
self.shape = "NONE" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks.
def onMouseDown(self, x, y, button, shift):
pass
def onMouseDownMap(self, x, y, button, shift):
mxd = arcpy.mapping.MapDocument("CURRENT")
df = arcpy.mapping.ListDataFrames(mxd)[0]
layers = arcpy.mapping.ListLayers(mxd, None, df)
rasterlayer = None
for layer in layers:
if layer.isRasterLayer:
rasterlayer = layer
break
if rasterlayer:
cellvalue = arcpy.management.GetCellValue(rasterlayer, "{} {}".format(x, y)).getOutput(0)
pythonaddins.MessageBox("XY: {}, {}\nCell Value: {}".format(x, y, cellvalue), "Results")
