Figura 77: Load OSM data dialog<br />

12.14 OpenStreetMap Plugin<br />

Click Ok to load your data. If this is the first time OSM file is loaded, the plugin must first parse the<br />

database. This may take few seconds or minutes - it depends on the amount of loaded data.<br />

12.14.4. Viewing OSM data<br />

After OSM data are loaded, you can identify map features using the appropriate tool. Use the<br />

Identify feature button on the top-left of OSM Feature widget. Using this tool you can easily explore<br />

all map objects. When the mouse cursor is placed over an object, you can see all information on it<br />

directly in the OSM Feature widget. There is also a dynamic rubberband displayed on the map so<br />

that the user is able to determine which feature is currently identified.<br />

The Properties tab of the widget contains of all feature tags. Clicking on the Relation tab shows<br />

you a list of all relations connected with identified feature.<br />

If you want to hold a feature for a while to be able to read its properties and relations, move the mouse<br />

cursor at the same time, try left-clicking while you are over the feature. Identification process will stop<br />

until next left-clicking.<br />

Sometimes there are more than one feature at a point where left-clicking was performed. This happens<br />

especially when clicking on cross-roads or if you didn’t zoom enough into the map. In this<br />

situation only one of such features is identified (and marked with the rubberband) but the plugin remembers<br />

all of them. Then (still in the pause mode) you can change identified features cyclical with<br />

right-clicking.<br />
