  1. G’day ‘GIS Area’ I’ve got a bit of a tricky conceptual problem and was looking to see if anyone had any thoughts. I have a vast area of low lying saltbush and grassy pastoral land (approximately 80km2) in which have been randomly placed several thousand lengths of white PVC piping protruding approximately a foot or so out of the ground more or less vertically (with no caps) above the majority of the grass and stubble. I’m attempting to use drones to scan the surface and get precise coordinates of every one of these lengths of pipe; however I haven’t been able to land on a method of doing this as yet. I’ve considered scanning the area with hyperspectral sensors and then performing a supervised classification of the data using the reflectance signature of the white PVC piping however the thin topographical cross-section of the pipes means too little of the PVC would be observable from a drone scanning the ground from directly above. The only thing I can think of to resolve this issue would be to tilt the sensor so that the resultant images capture the sides of the PVC rather than the tops and then adjusting the coordinates somehow. If anyone has any thoughts on this, or any other potential solution to my piping problem, I’d greatly appreciate the input. P.S. I'm quite a novice at remote sensing and airborne research so as jargon free a response as is practical would be appreciated also... Regards MattRNR
