How to use the new support for ground overlay maps?

[argus]

Hello,

in the latest update (vers. 1.14.5) kmz ground overlay maps are supported. But how can I use these maps?

Any hint is appreciated.

Cheers!

hi,
this feature is really in beta but it works in simple way
1. import KMZ file like in normal import
2. if will contain GroundOverlay layer, it will be displayed on map
3. to work with this layer (currently only hide/ show / delete), go to functions > map item manager
4. locus do not remember loaded overlays, so after you start locus again, you need to load it once more as in step 1.

..., go to functions > map item manager

currently that crash locus

What format uses locus for overlay maps? I tried export sample map with global mapper to jpg and png but locus crash just after import.

Hi Menion,

thanks for your quick reply. I will test this function and come back to this forum later, maybe...

This weekend I received a map for an upcoming hiking trip.
It's in KMZ format and I thought I should be able to open it in Locus as a GroundOverlay

Unfortunately I receive following error message errors:

errors-1327904297728.err

(789 Bytes) Downloaded 20 times

and also a crash:

crash-1327904375819.err

(3.46 KiB) Downloaded 27 times

KMZ can be downloaded from:

Could somebody please help me getting this map imported into Locus?

Thanks in advance

hmm when I start google earth, it show around 150MB in memory

when I load your map, it shows around 370MB ...

your map is really nice but is also really huge (KMZ file have 90MB). Don't know how other programs handle KMZ files, but as Google Earth, also a Locus loads all data at once. Unfortunately for this file it's not possible. I suggest to convert this file to some usable map format. Mapc2mapc support converting KMZ to some SQLite map format so you may try (I didn't test it, just hear somewhere)

[gynta]

Yes this 90MB kmz crashed here too.
Maybe menion can intercept this overflow error.

[dibrial]

I can't get the map to be opened in MAPC2mapc. It's importing it, but when I want to view or exported it, the message ‘No map loaded’ appears.
Any ideas?

[menion]

Hi Dibrial,
good news. Locus now handle your file ... slow, but works ...

[dibrial]

Great:grin:....I really hope to test it soon. I'm already back from Madeira and used the vector. It worked, but having some altitude lines would really have been helpful.....Pffff....I'll use it next time we visit the island.

[menion]

ok, fine ... seems to late but as you say - next time

Hi Menion!

As a GIS guy, overlays are just perfect for me. you are on a good way to make your app even more pr0! Good job.

But...
1. I loaded some kmz overlay with bitmap in It , this bitmap pixelated and lost resolution. So when I was zooming in, there were no details in my overlay, just big ugly pixels. Is it for purpose or could it be an error/bug? The whole kmz is ~7MB. Maybe I'm doing something wrong?

2: I loaded kmz with only vectors lines. The connected lines are just a part of one big canal system. its bad idea to show them as tracks. I don't want to see them as the separate parts. For me it would be great to just make them one object, one overlay. And don't divide them in separate parts. And their icons are very annoying. I know I can turn the icons off, but I don't want to turn the icon off also for real tracks. Think if I would have thousends of lines in one overlay. In this scenario, this list of tracks in Tracks menu would be very long and hard to manage. And the map itself would be unreadable with the icons.

[menion]

may you provide me some sample files? Without it, it's hard to improve current system, thanks ...

1. import KMZ file like in normal import
2. if will contain GroundOverlay layer, it will be displayed on map
3. to work with this layer (currently only hide/ show / delete), go to functions > map item manager

Is map item manager available in stable release or it is devel-only? I have Locus Pro 2.3.1 and cannot find the manager in functions
I have few topo maps in kmz format, they contain nothing but GroundOverlay tiles. After importing one of them, I can find unzipped jpg tiles in /Locus/data/import but can't see any way to display them.

[menion]

fully working. Map item manager have just moved from separate function in list of function into new tab in Map manager. So tap on map icon in top right corner and tap on tab "Items"

best is to place all your KMZ files into Locus/mapItems directory. Then all these files will be available in this "Items" screen

[mdmystko]

I needed more time to correct my phone type in seetings than you to notice and reply to my post, unbelievable
Indeed, there is a new tab "Items" in Map manager. It was trivial to figure out how to use it, I can see first of my maps already. Good design, thank you!

[menion]

hehe, you're welcome

I have already tested support for huge Ground overlays (around 90MB and it works nice) just be careful with tiles size. It should be in some useful size. Ideal around 256x256px. More then 1000x1000 may cause OutOfMemory errors so count with it ...
