Troubles & Questions / GEOCACHING
« on: June 30, 2011, 11:34:29 »
Hello,

I am re-discovering the power of Locus, and all the new functions and modifications .... following an update of the version on my Dell Streak.

Until now, I was using Locus as a companion software of c:geo, but now that c:geo will not be maintained, I was looking to back to Locus as some friends told me that Geocaching functions was also available in Locus ! I am premium member, so no trouble to use Locus with my favourite pocket queries ! and I support your will to increase such functions !

But this is not exactly the object of this post .... I have also discovered that, like Mobac, restrictions have been put on Map types .... some disappointments at the moment  :|  .... that rapidly disappeared when I discovered the ArcGis maps ....

My question is then : are ArcGis maps free of license problems ? no risk to have the same problem as for Google maps ?

To do the second step, you have to build a sqlite database that will contain the 3 files presented before and integrate the data and the map tiles. This operation should be done with a little pcsw containing a sqlite driver for the database creation and edition.
For me, i will use windev framework to do that.

I forgot to tell you that I found the solution ....

Using MapTiler (www.maptiler.org) you can create tiles corresponding to Google projection (x/y/z) from an .ECW file !

As output, you get a structured folder  :  <zoom>/<x>/<y>.jpg (with y numbering that you have to shift to get the Google Maps ...the Maptiler is compliant TMS "y" numbering,  but it not so difficult to convert using 2^zoom-y)

Then the second step is to build the SQLite database for Locus by integrating all these images taking into account the "z" translation  (17-z), using a small PC SW.

I think it's "17 - z", so zoom 0 on Gmaps == 17 in database

I confirm z in Locus is equal to  z-17  from Gmaps

hmm create TAR map and look. How to? On screen where are you selecting zooms to download, change type by middle bottom button

I will try ........ but not today.

OK ....

Structure of sqlite locus file :

- the database comprises 3 files : tiles, android_metadata, info
- "tiles" file structure :
ROWID
x INTEGER PRIMARY KEY
y INTEGER PRIMARY KEY
z INTEGER PRIMARY KEY
s INTEGER PRIMARY KEY
image BYTE (PNG IMAGE)
SQL : CREATE TABLE tiles (x INTEGER, Y INTEGER, z INTEGER, s INTEGER, image BYTE, PRIMARY KEY (x,y,z,s))
- "info" file structure :
ROWID
minzoom INTEGER
maxzoom INTEGER
SQL : CREATE TABLE info (minzoom INTEGER, maxzoom INTEGER)
- "android_metadata" file structure
ROWID
locale TEXT
SQL : CREATE TABLE "android_metadata" (locale TEXT)

so .... the structure of the database is OK now, but I have QUESTIONS :
- are x/y/z corresponding to MERCARTOR Google-like projection ?????? (as depicted here: http://www.maptiler.org/google-maps-coo ... rojection/)
- what is the meaning of "s" in "tiles" ?
- in "android_metada" : locale = "fr_FR"  (only one record)
- "info" is empty ????
- I have not found tared files on my sdcard ... is the description similar ?

Reverse engineering of LOCUS database and folders may be a good solution .... however, as little document describing the structure would be better for me  ....

Please, do you do have any written description of your file formats and database format ? I have made some googling about this, but did not find so much clear information ....

"GPSBabel converts waypoints, tracks, and routes" ..... :-(

.ecw file are raster maps compressed using wavelet technology (as JPEG2000) and with headers comprising calibration and projection data (see http://www.gdal.org/ or http://www.erdas.com/Homepage.aspx)

so what I need is a tool to convert my .ecw files into "rmap SQLite" or "trekbuddy tared" as indicated in the LOCUS tutorial ....

where can I find clear description of  "rmap SQLite" or "trekbuddy tared" file description ?
