Multidataset

The multidataset XML (.m6mmultidataset.xml) is used to setup and describe similar type datasets. A dataset is typically produced from the same source data/format.

All entries in this file are treated as hints and may be overridden by the map renderer.

All limits can be given as zoomlevels since Maria GDK 2.0. Use postfix "L" to parse limits as zoomlevel instead ofmapscale(f.ex. minvisible="15L" maxvisible="6L"). Mapscales will be converted to corresponding zoomlevels.

Example:

<multidataset>
  <globalsettings>
    <multidatasetlimits minvisible="1K" maxvisible="1000000K" 
                        simplestyle="10000K" label="10M"/>

<multidataset> is the root node of the multidataset-xml.

Child element	Description	Properties
	Global settings for multidataset.	C
	Templates for group settings.	O R C
	Filters used to add data files.	O R A

Globalsettings

Child element	Description	Properties
multidatasetlimits	Collection of scale limits that apply globally to this multidataset.	O A
groupsetting	Default groupsettings.	O C A
resourcereferences	Collection of style information hints to be used by the map renderer.	A
datasetclipborder	Dataset clip border setting. Used to prevent clipping of large point symbols at dataset borders.	O A

Multidatasetlimits

Scale/level limits that apply gobally to this multidataset. See for further information. Also used for setting overzoom parameter.

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.

Note: overzoom is implemented post version 2.0.1.

Attribute	Description	Properties
overzoom	Number of levels. Default value is 0.

Example:

<multidatasetlimits minvisible="0" maxvisible="256M" simplestyle="256M" label="10M" overzoom="4"/>

Groupsetting

Groupsettings under globalsettings act as a default template for the groupsettings listed in the groupsettingtemplate section of the xml.

Child element	Description	Properties
limits	Collection of scale limits that apply globally to this multidataset.	O A
clipborder	Layer clip border setting. Used to prevent clipping of large point symbols at tile borders.	O A

Attribute	Description	Properties
drawpri	Layer draw priority. Lower number equals higher priority. Default value is 100.

Limits

Attribute	Description	Properties
minvisible	Minimum scale for rendering layer. Use of scale factors (k/K/m/M) are allowed.
maxvisible	Maximum scale for rendering layer. Use of scale factors (k/K/m/M) are allowed.
simplestyle	Scale threshold (minimum scale) for showing simple style.
label	Scale threshold (maximum scale) for showing label.

Clipborder

Clipborder is only used when drawing points.

Attribute	Description	Properties
value	Clip border value in pixels.
