* at home:
 +
** fetch an overview tile set of intended sailing area zoomlevels ~1-14 (/w mobac, preconfigured downloads, etc.) and preload cache
 +
* on board while connected to internet:
 +
** grab detailed tiles zoom 15-18 of intended approaches/anchorages via web app through proxy and cache
 +
* under way /wo internet connection:
 +
** sail using cached tiles
 +
* aim:
 +
** keep stress on tile servers low (do NOT download all possible tiles of zoom levels 15-18 at home)
 +
* drawback:
 +
** a 'raw' tile store /w deep /{z}/{x}/{y} directory structure might cause trouble on (sd-card driven) rasPIs ...

tile server /w cache+proxy

draft

  • at home:
    • fetch an overview tile set of intended sailing area zoomlevels ~1-14 (/w mobac, preconfigured downloads, etc.) and preload cache
  • on board while connected to internet:
    • grab detailed tiles zoom 15-18 of intended approaches/anchorages via web app through proxy and cache
  • under way /wo internet connection:
    • sail using cached tiles
  • aim:
    • keep stress on tile servers low (do NOT download all possible tiles of zoom levels 15-18 at home)
  • drawback:
    • a 'raw' tile store /w deep /{z}/{x}/{y} directory structure might cause trouble on (sd-card driven) rasPIs ...
