Oh, hey, regular disclaimer, don't go walking off a cliff because you are using my map.

I built these in QGIS, a gis application (which is free btw). I too have been searching for about 3 years for a high quality topos. I thought MapBox was the OSM solution, but they stopped updating regularly and I see stuff getting close to 6 months old in MapBox now. I'm taking a web mapping course next term and will be inquiring about methods to do this, starting small and seeing if I can slowly scale up without breaking the web server bank.Webfoot wrote:How are you producing these contour lines? Could the process be scaled to large areas? I ask because it would be nice to have high resolution contour lines in OSM products, like those available from https://www.openandromaps.org/ which I use for primary navigation.
Code: Select all
gdal_contour -i 10.0 input.tiff output.shp
