I generated an OSM elevation contours file (using srtm2osm, from SRTM data), and want to use that in JOSM as a guide to mapping rivers, but can't find any way to make JOSM show the contours. Using JOSM, I downloaded the relevant region from OSM, created a new layer, opened the contours file (which took a while to open, because it's a big file) but I can't find any way to make the contours visible. The contours file does appear to be correct, as I successfully used mkgmap to show its contents on my GPS. So, am I missing something? Or does JOSM deliberately not show elevation contours? asked 22 Jan '11, 16:24  tongro closed 22 Jan '11, 18:22  Richard ♦ |

One Answer:
Apologies, it turned out to be a memory issue. The file opening was failing silently. Increasing the Java memory allocation worked. Matter closed. answered 22 Jan '11, 17:29 tongro |
It's really a Java issue, affecting any Java program, not just JOSM. You specify the memory allocation in the Java command. To allow up to 1GB you would do something like: java -Xmx1000M /usr/share/josm/josm.jar
