I have created a composite image of Landsat 8 using bands 2 to 7 (blue, green, red, NIR and SWIR) using ArcGIS 10.1. For bands 2-4, I've pansharpened them to 15m spatial resolutions using the panchromatic band, while bands 5-7 are in 30m spatial resolutions.
Will the different spatial resolutions pose a problem when I perform image classification later on?
