Hi Dane, Thank you very much for your help on this! As you suggested, we ran shapeindex with single thread script (generate_tiles.py) but we got the following error messages:
proj_init_error:failed to initialize projection with:+init=epsg:4326 World : 16 58199 25813 Empty Tile propjr_oijnit_e_rirnoirt:_fearirolre:df atio iled to initniitailaliizze e projec The above error might occurred since proj epsg file cannot be found so we downloaded win32 binary from proj.4 and set the PATH and PROJ_LIB. However, we are still getting same error message. The version of proj.4 is 4.4.6. At this point, we are not sure how to resolve this. If you have previous experience, please kindly let us know.
