Hello,

I have a set of landsat 7 layers, that look like this:

files = [ $
"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b1.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b2.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b3.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b4.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b5.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b6.tif" $
,"D:\ArcGIS\Programmieren in IDL\Landsat Daten\landsat_b7.tif" $
]

As well as several exercise points with one value referring to a layer each.
point1 = [10764,9737,8758,7702,20470,11250,7628]
point2 = [11993,11117,10083,9633,11021,11634,10856]
point3 = [11250,10393,9456,8347,8226,6585,6069]

How do I calculate the distance between each point and the layer stack? I tried using the DISTANCE_MEASURE function, but can't seem to figure out how to use it in this case.
