I would like to download all USGS SRTM 3 tiles for Ontario, Canada from the USGS site: http://dds.cr.usgs.gov/srtm/version2_1/SRTM3/North_America/
Where can I obtain the index that will assist me in querying the tiles I need to download. Alternatively, is there another easier way to identify the tiles?
When I was downloading the tiles for Manitoba, Canada I found a range of files then just downloaded the individual files from the site. Is there a similar range of files for Ontario?
