type: item
description: To all, I am a physical oceanographer who needs to use your idl program in my model output post-processing. While utilizing your utm conversion program (ll_to_utm.pro) in my research work, I have a problem due to zone change so that I encounter a discontinuity problems as follows; test_lon=[125.999,126.000] ; define test lon & lat test_lat=[36.000,36.000] ; test output for i=0,1 do print,i,test_lon(i),test_lat(i),ll_to_utm(test_lon(i),test_l at(i)) 0 125.999 36.0000 770330.54 3988106.3 1 126.000 36.0000 229579.34 3988109.1 I undrestand this is due to zone change from 51 to 52. I wonder how I can avoid this trouble in map drawing where my coastline data points lie over 125 to 127 E longitude. I appreciate your helps.
