das sieht doch gut aus. Zwei Dinge:
1) Die OSM-Daten stehen jetzt unter Odbl-Lizenz, ich habe nicht überprüft, ob sie von vor dem Lizenzwechsel sind.
2) Wie oft wird eine Position mittels GPS aufgenommen?

Webmaster | Archaeopteryx: 1) Ja, das mit der Lizenz weiß ich, muss mich erst umsehen, wie ich die Copyright-Mitteilung am besten daran anpasse, ohne dass sie zu lang wird, denn die Daten sind ODbL, aber die Tiles nach wie vor CC-BY-SA. 2) Es wird Geolocation.watchPosition() verwendet, und das ist dem Browser überlassen, wie oft ein Callback gesendet wird. Laut DougT sendet der Mozilla-Code das "wenn sich die Position signifikant ändert", so weit ich sehe, ist das maximal jede Sekunde. 2012-09-21 14:30 |
Harry from London UK | I'm an open street map editor with a firefoxOS phone, so Lantea was an obvious choice. I find it works well. I had the original ZTE open which just about worked, but now upgraded to an Open C which is a lot better -- more memory and CPU power, but especially the GPS seems much more accurate. Downside -- they've dropped the compass, which was useful, so now I know more exactly where I am, but cannot tell which was I should go until I have been moving for a while. Minor issue with Lantea -- the configuration buttons pop up every time you touch the screen, hide rather a lot of the map and take a while to disappear. I would prefer to have a small config icon brings up the buttons. Possible features -- when in centre mode, I'd like to be able to drag the map to see more in the direction I am going, but at the moment it immediately puts me back to centre unless I manually disable the centre mode. It would be good if dragging could temporarily disable the centre mode and have an icon to click when I want to go back to centre. Its good to see the OSM map notes -- I wonder if you could do the same with GPX points retrieved from either local files or static URLs which the user could configure and display in the same way. They could be preplanned route markers, conventional POI lists, OSM keepright errors or anything the user chooses. Conversely, it would be good to be able to save some geo-notes relating to a position. Identify a position (perhaps the current GPS location, but possibly instead that of a nearby landmark) and make a text note or maybe a photo). 2014-07-23 15:54 |
