tileNames = gtopo30s(latlim,lonlim) returns a cell array of the tile names covering the geographic region for GTOPO30 digital elevation maps (also referred to as "30-arc second" DEMs). latlim and lonlim specify the region as two-element vectors of latitude and longitude limits in units of degrees.

tileNames = gtopo30s(lat,lon) returns a cell array of the tile names covering the geographic region for GTOPO30 digital elevation maps. lat and lon specify the region as scalar latitude and longitude points.
