The vector mappackage XML (.m6mmappackage.xml) is used to setup and describe a collection of vector map datasets and thus enable the creation of a complete, complex map.


Note that scalebase and/or nominalscalefactor specified in the mappackage-xml will override settings for scalebase and/or nominalscalefactor in the multidatasetfiles.
Maria GDK 4.0 has added support for MBTiles-datasets with MapBox-styling using the <tileset>-parameter instead of <multidataset>. Note that only a subset of the Mapbox-style specification is supported so far.

The vector mappackage XML (.m6mmappackage.xml) is used to setup and describe a collection of vector map datasets and thus enable the creation of a complete, complex map.

Maria GDK 4.0 has added support for MBTiles-datasets with MapBox-styling using the <tileset>-parameter instead of <multidataset>. Note that only a subset of the Mapbox-style specification is supported so far.

Example: 

<mappackage visibility="Visible" name="Mappackage example">
  <mapversion value="1.0.0"/>
  <vectormapdataset id="Norge 0-25M">
    <multidataset name="OpenStreet" file="OpenStreetDataset/OpenStreetMap.m6mmultidataset.xml" minscale="500" maxscale="15000"/> 
    <multidataset name="Norge N50" file="Datasets N50/NorgeN50.m6mmultidataset.xml" maxscale="50000"/> 
    <multidataset name="Norge N250" file="n250-5mShape\NorgeN250.m6mmultidataset.xml" maxscale="250000"/> 
    <multidataset name="Norge N500" file="n250-5mShape\NorgeN500.m6mmultidataset.xml" maxscale="500000"/> 
    <multidataset name="Norge N1000" file="n250-5mShape\NorgeN1000.m6mmultidataset.xml" maxscale="1000000"/> 
    <multidataset name="Norge N2000" file="n250-5mShape\NorgeN2000.m6mmultidataset.xml" maxscale="2000000"/> 
    <multidataset name="Norge N5000" file="n250-5mShape\NorgeN5000.m6mmultidataset.xml" maxscale="25000000"/>
  </vectormapdataset>

Multidataset
Attribute Description Properties
name Key that identifies the multidataset.

maxscale Maximum valid zoomlevel (use postfix 'L') or map scale for this tileset. Use of mapscale factors (k/K/m/M) are allowed. O
Tileset

Use the tileset-parameter if you have a MBTiles-vectordataset with Mapbox-styling. Note that only a subset of the Mapbox styling specification is supported. 

<vectormapdataset id="OSM Bright">
  <tileset name="Bright" file="osm-bright.mbtiles" stylefile="\osm-bright-gl-style-master\style.json" minscale="20L" maxscale="1L" overzoom="6" resources="osm-bright-gl-style-master\icons"/>
</vectormapdataset>

Overzoom is used for drawing maps on levels where no data exists. The number of levels specified by the overzoom parameter controls the number of levels the mapservice can search upwards in the maplevel tree for data to draw. The first level encountered to contain data will be used.

Remember to specify relative path to additional resourcefiles (f.x. symbolfiles) using the "resources"-attribute if necessary.

Attribute Description Properties
name Key that identifies the tileset.
file Relative path to the MBTiles-file (vector tiles). Ignored if [[#Source][source]] is specified.
stylefile Relative path to the Mapbox-stylefile (json).
resources Relative path to folder containing additional resourcefiles (symbols, patterns etc). O
minscale Minimum valid zoomlevel (use postfix 'L') or map scale for this tileset. Use of mapscale factors (k/K/m/M) are allowed. O
maxscale Maximum valid zoomlevel (use postfix 'L') or map scale for this tileset. Use of mapscale factors (k/K/m/M) are allowed. O
overzoom Number of zoomlevels. Default value is 0. O
Child element Description Properties
source Setup for multiple sources referenced in Mapbox style. Supported since Maria GDK 4.3+. O A R

Source

Maria GDK 4.3+ supports Mapbox styling referencing multiple datasources. 

<vectormapdataset>
  <tileset name="norway" stylefile="norway_style.json" minscale="20L" maxscale="1L" overzoom="2" resources="\norway\icons">
      <source name="norway_simple" file="norway_simple.mbtiles" />
      <source name="contours" file="norway_contours.mbtiles" />
  </tileset>
</vectormapdataset>
Attribute Description Properties
name Key that identifies the source. Must match source-definition in corresponding Mapbox style.
file Relative path to the MBTiles-file (vector tiles).

Group

Mappackage groups enable serverside merging of datasets. This functionality is largely replaced by vectormapdataset.

Example: 

<mappackage>
  <group maskcoverage="MaskSemiTransparent">        
    <multidataset file="mgcp\FMGTMGCPTestdata.m6mmultidataset.xml" minscale="5000" maxscale="25000000"/>

multidataset Adds map multidataset information. O R A
Attribute Description Properties
maskcoverage Mask mode. Valid values are "NoMasking" (no pixels included in mask), "MaskSemiTransparent" (all not fully transparent pixels included in mask), "MaskOpaque" (only fully opaque (a=255) pixels included in mask). Default value is "MaskSemiTransparent". O

Vectordataref

Using <vectordataref> makes it possible for a mappackage to reference datasets located in other mappackages. The dataset(s) to reference must be wrapped inside a <vectormapdataset>-block and the <vectormapdataset> must have an defined id (f.ex. id="Norge2013 0-25M").

The maskcoverage-attribute on a vectordataref will override the maskcoverage-attribute on the referenced vectormapdataset.

Example: 

This mappackage...
<mappackage>    
  <vectordataref id="Norge2013 0-25M" maskcoverage="MaskSemiTransparent"/>
</mappackage>

...references dataset in this mappackage:
<mappackage>
  <vectormapdataset id="Norge2013 0-25M" maskcoverage="MaskOpaque">
    <multidataset name="N50" file="Norge\N50\N50.m6mmultidataset.xml" maxscale="40000"/>
    <multidataset name="N250" file="Norge\N250\N250.m6mmultidataset.xml" maxscale="200000"/>
  </vectormapdataset>
</mappackage>
