Troubles & Questions / sqliteDB autoload
September 17, 2013, 17:29:46
Can someone list the requirements for the autoload feature ? There are 2 options (same type only & otherwise).

My scenario: I have divided my country into 2 areas (north & south).

I have the following sqlite files

top.sqlitedb: This an over all map containing tile zoom levels 8-11 (9-6 in sqlite)
North.sqlitedb: This contains the northern region in zoom levels 12-16 (5-1)
South.sqlitedb: contains the southern region in zoom levels 12-16 (5-1)
North17.sqlitedb: This contains the northern region in zoom levels 17 (0 in sqlite)
South17.sqlitedb: contains the southern region in zoom levels 17 (0 in sqlite)

All the DBs have the provider in the info table as "0". (so they are same type: I assume).

Now, what I expected Locus to do is to load the necessary tiles for the current zoom level from the sqlitedb files. meaning tile for zoom level 10 from top.sqlitedb and tile for zoom level 17 from North17/South17.sqlitedb.

However, that is not happening. what does work is if I'm in North.sqlitedb, it will load tiles from both North.sqlitedb & south.sqlitedb as required. but if I zoom out of the range of the current sqlitedb file, it will not load from the other files.

What have I done wrong?

So I spent the whole day trying to figure out how to get maps into Locus.

sqlite: I have a large map (4GB) which becomes impractical in the long run. so I discarded after i processed level 16 (zoom level 1).
gmef: Locus seems to have a problem with intermediate tiles not loading. I haven't seen the missing tile at 100% zooms, but say I have level 12 & 16. at level 14, I think locus has problem with loading & then resizing so it skips tiles.
.bni: It kind of reads the zoom levels, but no tiles are shown. (shows: not exists)
.png.tile: reads the zoom level but no tiles are shown. (shows: not exists)


I read somewhere that .bni & .png.tile are not supported, but that post was a while back. I got frustrated and figured I look at the assembly to see if I can find the extensions. The extensions are there, so are these supported? Am I doing something wrong?

Hi,

I've spent a few days and made some offline gemf maps. The problem I'm facing is that in locus, I must scroll very very slowly inorder for the map to load.

I've tried single and multiple zoom levels. files from 2MB to 700MB. the problem is always there. Initially, the map will not show, if I zoom in and out, it starts loading the tiles and if I pan too quickly, it will skip tiles. I will have to move the white area off screen and then pan it back onscreen again very very slowly.

the gemf files are generated with 1 range per zoom level with a lot of empty tiles. however, locus is showing empty areas within regions where tiles exist. Its not the gemf file as it eventually does load the tiles, if i pan around slowly.

A white map icon with a red thunderbolt shows up on the left, when its not able to load tiles. haven't been able to figure out what it means. tapping on it goes to quick map switch.

sometimes, it loads only 1 title. I have to zoom into the tile till its covering the screen and then zoom out. after that, locus starts loading the rest of the tiles.

The images format is jpg.

has anyone else experienced this ?

Does locus support just loading images from z/x/y.jpg folders ?
