OpenSeaMap-dev Diskussion:Downloadable Raster Charts: Unterschied zwischen den Versionen

Version vom 6. Februar 2015, 09:52 Uhr

Lets talk a bit about amounts here and not low stress or high stress. Using the charts offline on a mobile device. Lets say the display is about 1024x1024 Pixel, then we will need at least 16 tiles per map. If we start on zoom level 8 with the bounding box and continue to zoom level 16 for the harbours, we need around 2 Mio tiles. This 16 tiles on zoom level 8 is about the northern Adria. If we want the Channel just skipping Lands End up to the belgian coast, this would be 6 by 5 on zoom level 8.

 * Hi Alexej, do not understand this paragraph!? 2 test datasets of mine:
 ** INT-1463 bei zoom-level 13 (s="53.7" n="54.25" w="7.4" e="9.05"):<br>x: 37<br>y: 21<br>total: 777<br>[http://kap.grade.de/Europe/Germany/]
 ** river Ruhr<br>zoomlevel=16<br>~ 370 tiles<br>[http://wiki.openstreetmap.org/wiki/KAP-Dateien_aus_OSeaMap_erstellen#Python-Tool]
