A list of georeferenced points is:
coord = {{3.54231*10^6, 5.43395*10^6}, {3.54235*10^6,
5.43395*10^6}, {3.54239*10^6, 5.43396*10^6}, {3.54231*10^6,
5.43398*10^6}, {3.54235*10^6, 5.43399*10^6}, {3.54239*10^6,
5.434*10^6}, {3.5423*10^6, 5.43402*10^6}, {3.54234*10^6,
5.43403*10^6}, {3.54238*10^6, 5.43404*10^6}, {3.54229*10^6,
5.43406*10^6}, {3.54233*10^6, 5.43407*10^6}, {3.54237*10^6,
5.43408*10^6}, {3.54228*10^6, 5.4341*10^6}, {3.54232*10^6,
5.43411*10^6}, {3.54236*10^6, 5.43412*10^6}}
I would like to label each point of this list with the number of the position of the point in this list. How can I do this?
