Own offline maps with seamarks

[Glensimar Garcia]

Hi Guys!

I'm trying to create my own offline map but i would like to include seamarks on it,

Can anyone give me a hint to do this?

[Emux]

You mean something like this ?

You can start from our guides here and here regarding map creation.

Hi Emux!

I already have a downloaded map that works well, and overlay one layer with seamarks (buoys, beacon, etc.).Attached image. But sometimes the app gets very slow when loading the layer with the seamarks. So what wewant to do is generate a map with included seamarks, I read several posts but I could not do this.

Thanks for links..

[Emux]

You can overlay items on a map with two ways:

- The first (as you already tried) is with overlays on a ready map
(see our OverlayMapViewer for examples)

If you have many items you better use a separate thread (e.g. AsyncTask) for handling them.


- The second way is building a new map with the items included in it.
For that you need to read our guides (like the two mentioned in previous post)
That way is faster in responsiveness, but you may loose some of the Overlay features, like touch listeners on each item.

Essentially for creating maps, we provide a plugin for Osmosis tool.
And you'll need to use a custom tag-mapping for declaring the extra layers in the map creation process.
And then modify accordingly the render theme to describe how your new layers are to be rendered.

I strongly suggest to start with our documentation.

Thank you Emux.. 

Anything I let you know!!

Hey Emux

If you have many items you better use a separate thread (e.g. AsyncTask) for handling them.

interesting Idea to use a seperate Thread. Can you give me a hint whats the best way to do that?

That depends on how you retrieve the data which you want to overlay on the map.

There can be various sources like from web services, from databases, from structured data (xml, gpx) and many many others.

The data organization - if long running - is recommended to not happen on main thread, in order to not "block" the application.

Specifically for AsyncTask, the data retrieval can be in doInBackground and the actual overlaying in onPostExecute.
See our PoiSearchViewer in Samples dev for an implementation example.

But Android background processing has more members, you can find guides online, e.g.
http://www.vogella.com/tutorials/AndroidBackgroundProcessing/article.html

As always Thanks a lot! I give a try

[Glensimar Garcia]

Hi Emux!

Can you help me to fix this?

Unable to load plugin class (org.mapsforge.map.writer.osmosis.MapFileWriterPluginLoader)



I try this that i found in a previous post:

This has gone for me: 
1) copy 'mapsforge-map-0.3.0-jar-with-dependencies.jar' into 
'osmosis/lib/default' directory 
2) Create file 'osmosis-plugins.conf' into 'osmosis/config' directory 
3) Add this line to the file: 
org.mapsforge.map.writer.osmosis.MapFileWriterPluginLoader 

but i do not know if this works the same with the last mapsforge-map-writer-dev-SNAPSHOT.jar

Thanks..

[Ludwig]

There is no change in this. 

If you follow the instructions closely, it will work.

[Emux]

For using the map-writer plugin, we have detailed instructions in our docs.
(if you find any difficulties please inform us to improve them)

We recommend to download the latest map-writer plugin and use it with the latest Osmosis.

Those instructions you mentioned (I have written them in old times), now we are more flexible with the plugins. :)

About the OOM if you use the type=ram you need (depending on your map size) to give Osmosis more memory via the -Xmx option (based on your actual RAM).
Or you can try the type=hd for more safe but slow map building.

--
Emux

[Ludwig]

It says your JVM is out of memory. We use quite a bit of memory making maps, increase memory with a option to the java command such like -Xmx8524M (depending on how much memory you have, the more the better), or use the -hd option (much slower).

Hi Guys!

i try this:

bin/osmosis --rb file=berlin.osm.pbf --mapfile-writer file=berlin.map --type=hd

and now i get:

Execution aborted.
org.openstreetmap.osmosis.core.OsmosisRuntimeException: Task type type=hd doesn't exist.

[Emux]

The options of the --mapfile-writer don't have "--":  type=hd

[Glensimar Garcia]

Yes.. Thanks!

[Glensimar Garcia]

Hi Emux, Ludwig.

I try with the option hd and takes a long long time to process. But still at the end give me an error of Java heap space.

So i change computer with more memory and after doing the same i get this:

[Emux]

The log shows pbf reading by Osmosis (a prior Mapsforge stage).

So are you using the latest Osmosis with unmodified its libraries (except adding map-writer plugin) ?

Are you using a custom pbf file and are you sure it's constructed correctly?

--
Emux

[Ludwig]

Probably truncated file, check size

A test I would do, is processing the pbf without map-writer to see what actual happens with the input data.

e.g. convert the pbf to osm and see if the process finishes:
osmosis --rb input.pbf --wx output.osm

Thanks!! :)

[Glensimar Garcia]

Good Thank you!

I let you know..

[Kasimir]

Hi Guys,
i upfollow this all and get a Map what only has under 1 MB at least after 7 Hours Waittime ;-(
i add both files here - Protocoll Output of Mapwriter Processing and the final File itself.

Has any of yours a Idea, what was wrong here ?

Final i wish you good Luck for the new Year !

Kasi

[Emux]

- Using a large pbf with hd, long process time is not strange

- Your bounding box seems wrong, it's somewhere east of Africa

Emux

[Kasimir]

Hi Emux,
i use the bbox from Glensi Informations, where do i found correct Parameters for only Germany, then i think bbox was the Problem, right ?
regards Kasi

[Emux]

You can find coordinates for any area in web maps on net, each has its own way.
e.g. if you're looking for cutting a specific area for a country.

Or search for tools like that: https://osm.wno-edv-service.de/boundaries/

Note: In map-creator we use poly files for more precise cutting with live bbox calculation.

Atlas also can give you coordinates info in its status bar or via right click on map.

No, proper bounds can be seen in screenshot.

Look after the proper order of coordinates as seen in docs:

I have now download a Polyfile here, but how to input this into osmosis..

Normal i must input here the input file and the boundary box like this =
C:\osmosis\bin>osmosis --rb file=/osmosis/out.osm --mapfile-writer type=hd file=/osmosis/germany-1.map bbox=55.04061432771673,4.918701171875,47.52863469527167,14.350830078125 -Xmx16384M

i add out.osm, then say what is output file and final i add the Boundary Box, but if i want to use Polyline file - how is this to add ??
regards Sven

[Kasimir]

If i use this, i get the follow Error =

Read our map-writer documentation.

We don't use poly files, just bounding box coordinates.

[Kasimir]

O.K. i change back to bbox
but i have now check with a boundary tool - and get this back
left=5.7331 bottom=47.2949 right=15.0275 top=54.8899 - this are the coordinates for Germany
and nearly this i have input in the command line, but you say this is wrong parameter for south Africa in mapwriter ??

What is here wrong ?
i use yet bbox=5.7331,47.2949,15.0275,54.8899

Or is the input of mapwriter commandline different ??
left=5.7331 bottom=47.2949 right=15.0275 top=54.8899 ??

regards kasi

[Emux]

left = minLon
bottom = minLat
right = maxLon
top = maxLat

And the command line is valid with:
bbox=minLat,minLon,maxLat,maxLon

Please (all of you) invest time to study our docs and their examples!

Emux

[Kasimir]

Ahhhhhhrrrgggghhhhh...this was the Error by me...
O.K. Emux - thanks very much, now i can start the next try and hope in 8 Hours i get now a better result. The old Map was failed, by using wrong parameters..
I let you know if i was successful ;-)
kasi

P.S.
Have a nice Day and wish you all the best for the new Year ;-)

[Kasimir]

Happy new Year to all

i have now successful generate a Map with 200 mb more datas and i can read the Map in a Offline Map reader, but

i see no Seamarks in this Map ??

After i think about this a while the Problem looks like, that the xml File have Coordinates and Positions and Colors, but there is no Graphic inside the Files.
So can it be, that the Map now have all Positions and what it need, but dont know how to generate the Graphics for this Positions ?

And also the next Question is, how to add Graphic into the Files - how does a Map insert the right Graphics from that second File Seamarks, what is to 100 % only a File, what says how to look and where to insert on a Map and also inwhat file it must have the Graphics for that?

I think, here is the Problem for not Viewing any Seamark - The Map itself is finished without big Errors.
If any what can help me here to understand, how a Graphic is inserting in a new Map - and how to modify Files ?

Regards Kasi

[Emux]

- What goes in the map with the map-writer, is defined with the tag-mapping xml (see here).
If you don't define one then the default one is used.
If you have custom data then you need to have one describing your data (e.g. extending the default one).

- After the map creation you need an appropriate render theme xml (see here).
In it you declare rules for how the map will be rendered on the screen.
Apparently your custom data will need additional rules too.

See our aforementioned documentation and the accompanied xmls to understand their meaning and use.

--
Emux

[Glensimar Garcia]

Hi Emux!

So.. We have to modify the tag-mapping xml inside the plugin to add my custom tags? 

And then generate again the map with osmosis?

Because i have the new rules for rendertheme, but not show anything i supposed that is because i did not have a custom xml file. 

(Ahh!  how can i include tag-mapping.xml do it without errors? Because I have read that if I change the contents of a .jar file may be damaged.)

Thanks!

[Emux]

You don't need to modify the default tag-mapping.
Just pass your custom one's path via the 'tag-conf-file' option.

See our documentation for details.

[Emux]

tag-conf-file is an option for map-writer task, not an Osmosis task by itself.

So it does not need the '--' prefix, you can write it like the other options (type, file, etc.):
tag-conf-file=...

Oops, have found self the Problem - the right Syntax is

osmosis --rb file=/osmosis/out.osm --mapfile-writer type=hd file=/osmosis/germany-2.map tag-conf-file=/osmosis/tag-mapping.xml bbox=47.2949,5.7331,54.8899,15.0275 -Xmx16384

thx Gina

Hi Folks
Yepp we got it now..
We are now on the Way to include the right Tags for the Renderfile.
Thanks to EMUX and Ludwig from Team here - this  was very helpful and most of Errors we get by own stupid trys and misunderstandings.

Now we have done the first Map.. Thanks for it

[Glensimar Garcia]

Hi Emux, Ludwig!

Thanks for the help! :)

We are creating our tag-mapping to include the seamarks that we want in our map..

I have this in my seamark file:

<node id="824651056" lat="53.8846189" lon="13.8685188" version="3" timestamp="2014-07-13T23:52:21Z" changeset="24130810" uid="597190" user="Krille von Stralau">

    <tag k="buoy" v="lateral_port"/>

    <tag k="buoy:colour" v="red"/>

    <tag k="name" v="PN 90"/>

    <tag k="seamark" v="buoy"/>

    <tag k="seamark:buoy_lateral:category" v="port"/>

    <tag k="seamark:buoy_lateral:colour" v="red"/>

    <tag k="seamark:buoy_lateral:shape" v="pillar"/>

    <tag k="seamark:buoy_lateral:system" v="iala-a"/>

    <tag k="seamark:name" v="PN 90"/>

    <tag k="seamark:type" v="buoy_lateral"/>

  </node>

And i want to know if i include this:

 <osm-tag key="seamark:type" value="buoy_lateral" zoom-appear="10" />

Do I have to be specific in what buoy:shapes or color we want ? or tag-mapping include all nodes that have the seamark:type = bouy lateral?

because tag-mapping is becoming in a laaarge file..

And the same for all type of nodes? 

I hope explain myself.

Thanks!

[Emux]

I'm afraid there are specific official OSM tags that are included automatically and recognized from render themes:

For nodes are:
name
addr:housenumber
ele

For ways are:
name
addr:housenumber
ref

So in your case you can declare in the tag-mapping the node types and in render theme refer to each type with its own symbol / color.

e.g. see how we declare the amenities in tag-mapping and in render theme.

--
Emux

[Glensimar Garcia]

Oh Ok!.

And, for example, how can i do if my seamarks file is some like this:

<tag k="seamark:type" v="distance_mark"/>

<tag k="seamark:distance_mark:units" v="kilometres"/>

<tag k="seamark:distance_mark:units" v="kilometer"/>

<tag k="seamark:distance_mark:units" v="km"/>

Do I have to declare all three possible values? There is a wildcard for this cases ?

If I understand correctly you want to render a layer based on more than one tags.

Like the road network, which is composed of tags: highway, access, oneway, etc.

I suggest to see how we declare it in tag-mapping:
Here for main tag and here for it's additional tags (access, oneway, etc).

Then in render theme the tags can be combined like around here.

BTW I don't quite understand what you want to do with the units in tag-mapping.
I suggest to first define in its "simplest" form how you want to render the nodes and then proceed with the tag-mapping / render theme writing.
e.g. is it all about nodes with different symbol based on tag's values?

Yes Emux.. I'm doing main tags and additional tags.

My question is if exist any wildcard to those tags that can contain multiples or different values... 

Distance marks is an example.

Thanks.. :)

No, in tag-mapping we have to declare all tag values that are to be included in the map file.

I know it's not convenient..
And actually built marine maps with several thousands of lines for this purpose only :)

It would be good if we could use wildcards and number calculations in tagging (like in CartoCSS).
e.g. to include the elements with depth > 500m

Nevertheless in render theme you can use wildcards (see here).
