When I am looking at the pure data in a certain area (like in the data layer or in any editor), where can I see the length of one way element in meters? asked 24 Jul '10, 11:26 stephan75 Jochen Topf |
Pure OSM data only indirectly contains length information: The lengths themselves aren't stored anywhere but can be calculated from the nodes' coordinates. Therefore, you need a tool that calculates and displays this information. OSM editing applications typically offer this feature:

Maperitive can show you lengths of ways:

Found one more on my own: Maybe the most simple way to see the length of an OSM way element in a kind of data layer is to load the area (or just the way) in the editor Merkaartor http://wiki.openstreetmap.org/wiki/Merkaartor. You only need to hover over the way with the mouse, or select it. The length is displayed in the information panel on the right of the screen. answered 27 Jul '10, 15:51 stephan75 |
OSM data contains only the geometries stored as nodes, ways and relations. If you want to obtain the some statistics on an element, you will need to work with tools like Postgis or specialized program. Postgis 1.5 has a new geography type which can be used to return numbers like length, area in meters. You would need to use osm2pgsql to import your data and then create a geography column based on the geometry column created by osm2psql. This method is quite complicated and should mostly be used for more advanced users. answered 26 Jul '10, 12:51 Melaskia |
