This article is an update of the article Making a topographic map with QGis<\/a> which dates from version 2.18 .<\/p>\n\n\n\n

The SRTM project now provides worldwide coverage of terrain elevation data. It’s now very easy to make your own topographic maps with QGis.<\/p>\n\n\n\n

Here we look at:<\/p>\n\n\n\n

-how to download elevation data for the area we’re interested in<\/p>\n\n\n\n

-how to format the display style to match topographic map standards<\/p>\n\n\n\n

-how to enhance visualization with a \u00ab\u00a0shading\u00a0\u00bb layer<\/p>\n\n\n\n

-and finally, how to generate contours.<\/p>\n\n\n\n\n\n\n\n
