Re: java heap error message on rasp pi 3 when trying to download maps
|
I sent a snip of my set screen, and although not wide ( and it wont go wider) I see 83.... west? and 42....north
the four folders are labelled n37 n38 n40 and n41.? yes there are files inside those folders..
i am not worrying yet about unchecking all the trees (lol)? ?and Buoys yet.? ?I would like to see a map first and have the local aprs hams show up in the correct position on my screen..
oh, and yes I have activity on my screen, just no map to follow where they are.

Pan or zoom the map a bit. It doesn't reliably recalculate the map when download is complete.
Also, did you download in the correct area? There have been bug reports when people downloaded using East longitude instead of West longitude, so they had no map data for Missouri but lots of data for Afghanistan (for example) cluttering up their disk drive. If you go to File->OpenStreetMap->Download Pre-Imported Tiles again, the black rectangle should now have a clump of blue and/or white dots on it indicating 1x1-degree tiles for which you have downloaded map data. The upper-left quadrant of the rectangle covers North America and the Caribbean, the lower-left quadrant is South America, and the right half is the corresponding Eastern hemisphere of the globe. So, is that clump of dots in the correct place relative to where your station location would appear on a world map? Note that those 4 directories you pointed out should be named with the latitudes of the 1-degree chunks you downloaded. Since you have an Ontario Canada callsign prefix, I'm assuming you should have N43 and N44 directories (assuming you're around Toronto, although you might have N48 and N49 if you were in Thunder Bay).

No, that's the one that's probably going to melt your Pi, assuming you have enough non-SD-card storage to handle the import (an SD card can't handle the number of write cycles involved in an import), and are willing to wait a few days.
You should use File->OpenStreetMap->Download Pre-Imported Tiles, which allows you to bypass the painful and resource-intensive process of importing the PBF file into YAAC-format map data.
For performing the full-planet import, I use an 8-core 3.0 GHz gaming server with 36GB of RAM and a solid-state disk just for the DB index files (which has been replaced twice over the development lifetime of YAAC due to wearing it out from imports), and it still takes over 20 hours.
