Is there a quick way in blender that I can use to delineate all the boundaries of the drawing and make them appear on a uv sphere, making it interactive in blender?
P.S. I'm in cycles

Your question is unclear. What boundaries do you want as a mesh? Guessing you want the boundaries of the drawing as a mesh you can use GIMP.
Open up the image in GIMP and select all lines. This is best done using the 'Select by Colour Tool'. Having everything selected, you have to click on 'To Path' in the Select Tab. Then go to the path window (by default on the right hand side) and right click your path and select 'Export Path'. Name your file *.svg. Then activate the addon 'Import-Export: Scalable Vector Graphics (SVG) 1.1 format' in your Blender user preferences. Save your user settings if you want it to be activated on startup from now on. Then go to 'File' -> 'Import' -> 'Scalable Vector Graphics (.svg)'. Choose your file and press 'Import SVG'. Now you have your path imported as a curve. In order to convert it to a mesh press Alt+C while hovering over the 3D View with your mouse. Then select 'Mesh from Curve/Meta/Surf/Text'.
