Edit Mapsforge MAPS

[charles galvez]

I'm Creating an Offline Map for Android.But i only need a certain part of the Map.At the moment I can View my whole country using Mapsforge.
The map is provided by Mapsforge.What I want is to get some continent of my country.I Don't want to use MOBAC.(too large file) Thank you!

You can recreate the map with the map-writer Osmosis plugin, using a bounding box and limiting the map file at the desired area.
We have examples in the Wiki guides.

Is there any software that can just cut certain part of the map?

[Emux]

Raster maps or vector maps?

For raster maps there can be many (as MOBAC).

For vector maps you need to use Osmosis with map-writer plugin.
Input osm files can be found at Geofabrik.

I cant understand the installation for osmosis. is there any video tutorial for that?

Osmosis is a 'generic' Java OSM tool, so many guides can be found online.

For map building it can be used simply by unzipping it and putting the map-writer plugin jar in its osmosis/lib/default/ subfolder.

Then proceeding with the proper command line.

If i use OSMOSIS can i use it to copy certain part of the map and use it with mapsforge? thanks

Create a new map file yes (not modify/copy an existing one).

Thank you for your help. I still cant find Step by step tutorial. 

I Followed this tutorial on how to install OSMOSIS but I didn't get the result shown on this link. Osmosis Installation Link-

I Extracted the osmosis-latest.zip C then followed the instruction.

This is always what i got when following the instruction.

Try putting Osmosis in a dir path without spaces.

I Hope I did what you are saying in this Image. 

I extracted the osmosis in my downloads and does the Instruction for installing osmosis.

Osmosis is not a Window UI application, but a command line tool.

So you must run it in a shell (command prompt).
Also either put its bin folder in the environment path (to run it from everywhere) or be in its 'bin' subfolder and then run it.

Apparently there is some version error in osmosis.bat file.

Check for a solution here:

Thank you so much!

That solved my problem. 

Now i'll study how to use Osmosis! thanks.

is this necessary,

putting this line of code in osmosis.bat?

"IF "%JAVACMD%"=="" set JAVACMD="C:\Program Files (x86)\Java\jre7\bin\java" 

thanks.

It's usually recommended to have set JAVA_HOME and have java exe in the path.

But Osmosis should work without changes.

Thank you. just to be sure am I getting the result correct? I write some code base on the tutorial but gave me some error.

BTW. I downloaded the mapsforge-map-writer-dev-SNAPSHOT.jar and Paste it to osmosis\lib\default.

(try posting text command examples via copy/paste, not images)

A simplest map creation command with bounding box is:

osmosis --rb file=country.pbf --mw file=country.map bbox=minLat,minLon,maxLat,maxLon map-start-position=lat,lon map-start-zoom=14

[charles galvez]

Sorry. It says 'Osmosis' is not recognized as an internal or external command.

Put osmosis.bat in windows and run it with the proper paths.

I put it in windows and change the path and run the command like what you have given. but nothing happens.

C:\Windows>osmosis --rb file=philippines.osm.pbf --mw file=country.map bbox=13.0

00,122.00,13.000,122.0000 map-start-position=13.0000,122.0000 map-start-zoom=14

I do not know what else is wrong, but if you just extract a single point from a map, I would not expect too much.

What do you mean sir?  Yes thats what i want. I want to extract some place in the map then use it in mapsforge.

[Emux]

(You seem playing inside Windows folder?)

Make a clean folder, copy inside the osmosis and pbf and run from there.
It's better setting absolute paths as parameters, just to be sure.

Also post (copy/paste) the result for us to understand the problem.

[Emux]

Ludwig is right, you cannot extract an area where min limits are equal with max limits.

That's a bounding box expressed as a point, the bounding box must have a surface size.

Try something like that:
bbox=12.5,121.5,13.5,122.5

Should I just start from the beginning of the tutorial,

   or should i make a folder inside windows and run the osmosis.bat using the shortcut i created? 

  This is what i get when i put osmosis.bat and the shortcut that runs the osmosis.bat(based on the tutorial i should make a shortcut)

C:\Windows>"C:\Windows\osmosis.bat"

Usage: java [-options] class [args...]

           (to execute a class)

   or  java [-options] -jar jarfile [args...]

I get this when i changed the bbox values.

Im running osmosis.bat (using shortcut.bat).

C:\Windows>osmosis --rb file=philippines.osm.pbf --mw file=country.map bbox=13.0

00,122.00,13.000,122.0000 map-start-position=13.0000,122.0000 map-start-zoom=14

[charles galvez]

Someone pls. I still need Help.
Or you can run Team Viewer for me. :'(

[Emux]

I recommend to take it step by step and run the commands in a shell.
When you run it successfully you can create a batch file of them.

So again, place in a clean folder the osmosis directory with the map-writer plugin in osmosis/lib/default/ subfolder, and the country pbf. Then run:

osmosis\bin\osmosis.bat --rb file=country.pbf --mw file=country.map bbox=minLat,minLon,maxLat,maxLon map-start-position=lat,lon map-start-zoom=14

Note: put proper bounding box coordinates (i.e. not equal min/max).

In case of error, provide the full command line you use and the command prompt log (right click copy/paste).
