5.6. Vector layer styles

Styles describe a way of rendering for geodata and are one of the resources of NGW. Style is added to a map to display geodata.

5.6.1. Formats

By now NextGIS Web supports two rendering libraries: “Mapserver” and “QGIS”. You can write Mapserver style yourself as a text. QGIS style you can only download from related qml file, it has much more settings.

5.6.2. QGIS Style

Style is related to a single layer so there is no item “Style” in the main resources list. To create a style you need to open layer properties of the layer you want create style for.

In actions pane “Create resource” click “QGIS style” (see Pic. 5.63.).

Pic. 5.63. Selecting QGIS style resourse

After the selection of “QGIS style” create resource dialog will open and will look like :numref:` name_qgis_style`. On the “Resource” tab enter the display name.

Pic. 5.64. Name of QGIS style resource

Field “Keyname” is optional. You can also add resource description and metadata on the corresponding tabs. Tile cache settings are described in details in this section.

Switch to “QGIS style” tab and click “Select a file” button in the “QML file” field or drag a file to this field (see in Pic. 5.65.). Here, if necessary, you can select the SVG marker library resource, which contains the icon to be displayed on the web map.

../../_images/upload_svg_qgis_style_en.png

Pic. 5.65. Upload QML file

Warning

QML file to upload should be created in NextGIS QGIS and saved on the PC (Pic. 5.66.). To create a style using SVG markers, you need to specify the SVG marker type in the layer properties and write the full path to the file on the local machine (Pic. 5.67.). The file name and format must match the one loaded in the SVG Marker Library resource that the user selects when loading the QML file.

5.6.3. Mapserver style

To create MapServer style open layer properties of the layer you want create style for. In actions pane “Create resource” click “MapServer style” (see in Pic. 5.69.). On the “Resource” tab enter the display name.

../../_images/ngweb_window_create_resource_mapserver_pic_eng.png

Pic. 5.69. Create resource dialog for MapServer style

Field “Keyname” is optional. You can also add resource description and metadata on the corresponding tabs. Tile cache settings are described in details in this section.

Switch to “MapServer style” tab and write a style manually (see in Pic. 5.70.).

5.6.4. Tile cache

Caching provides faster rendering of web map layers. The tile cache settings tab while creating styles consists of the following settings (см. Pic. 5.72.):

  • Enabled checkbox;

  • Allow using tiles in non-tile requests checkbox - the requested image (not a tile) will be prepared from previously cached tiles (if available);

  • Input field Maximum zoom level - a threshold value, above which the cache is not accessed and the image is formed “on the fly”;

  • Input field TTL, sec (Time to live) - a time of storage of tiles on the server in seconds, after which the image will be formed again on the next request. TTL = 0 means that the storage time is unlimited.

5.6.5. Adding a style on the map

To edit a web-map click pencil icon near it or click the web-map and in actions pane “Action” select “Update”. In “Update resource” layer select Layers tab (see in Pic. 5.73.).

Here you can do the following actions:

  1. Add layer

  2. Add group

  3. Remove

../../_images/select_svg_style_en.png

Pic. 5.73. Adding QGIS style on the map

Click “Add layer” and in opened window select a layer with QGIS style, then click “OK”. After that click “Save” (see in Pic. 5.74.).

../../_images/ngweb_select_file_upload_web_map_eng.png

Pic. 5.74. Selection of a layer with QGIS style to add on a web-map.

In actions pane “Web map” of web-map properties window select “Display”. The map will open, layers tree will be on the left of it. To hide/display a layer place a tick near the layer (see in Pic. 5.75.).

5.6.6. Map style tags

To change a style or to create a new one it is recommended you take a code of some existing style and then modify it, so there is no need to start creating a style from scratch.

5.6.6.1. Common tags

  • <color red=”255” green=”170” blue=”127”/> - the color of a fill or a line

  • <outlinecolor red=”106” green=”106” blue=”106”/> - outline color

  • <width>0.5</width> - a width of a line or an outline of the polygon.

  • <outlinewidth>3</outlinewidth> - outline width

  • <minscaledenom>1</minscaledenom> - do not display a feature if the map scale is larger than value

  • <maxscaledenom>100000</maxscaledenom> - do not display a feature is the map scale is less than value

5.6.6.2. Markers

../../_images/mapstyle_hatch_demo.png

Pic. 5.76. A demo for different hatches.

  • <symbol>std:circle</symbol> - marker type

  • std:rectangle - rectangle

  • std:circle - circle

  • std:diamond - diamong

  • std:triangle - triangle with peak at the top

  • std:triangle-equilateral - triangle with peak at the bottom

  • std:star - five-pointed star

  • std:pentagon - pentagon

  • std:arrow - arrow (by default is top oriented. Rotation could be set using a tag <angle>45</angle>)

  • std:cross - +

  • std:xcross - x

  • std:line - short line

  • std:hatch - long line texture

These markers could be used to draw a line, to fill a polygon or to display points. Also they may be combined to a complex symbol:

       <class>
           <expression>"industrial"</expression>
           <!-- Industrial areas -->
           <style> <!-- hatch with a right slope -->
               <color red="255" green="50" blue="50"/>
               <width>1.4</width>
               <symbol>std:hatch</symbol>
               <gap>10</gap>
               <size>5</size>
               <angle>45</angle>
           </style>
           <style> <!-- hatch with a left slope-->
               <color red="255" green="50" blue="50"/>
               <width>1.4</width>
               <symbol>std:hatch</symbol>
               <gap>10</gap>
               <size>5</size>
               <angle>-45</angle>
           </style>
           <style> <!-- Outline -->
               <outlinecolor red="255" green="50" blue="50"/>
               <width>0.5</width>
           </style>
</class>
  • <size>2</size> - marker size in pixels

5.6.6.3. Line features

  • <gap>10</gap> - a step size for dashed line (used with <symbol>std:circle</symbol>)

  • <width>8</width> - width of line in pixels

  • <classitem>PLACE</classitem> - filter by attribute PLACE. Also see example in #Filtering. The following operators are supported:

    • attribute name

    • !=

    • >=

    • <=

    • <

    • >

    • =* - case insensitive string comparison.

    • =

    • lt - less than

    • gt - greater than

    • ge - greater or equal

    • le - less or equal

    • eq - equal

    • ne - not equal

    • and - AND

    • && - AND

    • or - OR

    • || - OR

  • <linejoin>round</linejoin> - line draw at corners

  • <linecap>round</linecap> - line draw at the beginning and at the end

../../_images/admin_mapstyles_linecap.png

Pic. 5.77. <linecap>butt</linecap> / <linecap>round</linecap> / <linecap>square</linecap>

  • <pattern>2.5 4.5</pattern> - dash template

  • <angle> - marker rotation angle. Hatch could also be rotated.

5.6.6.4. Labels

  • <labelitem>a_hsnmbr</labelitem> - attribute name for labelling.

  • <minscaledenom>100</minscaledenom> - do not show a label if a scale is larger than 1:1000

  • <maxscaledenom>100000</maxscaledenom> - do not show a label if a scale is smaller than1:100000

  • LABELCACHE [on|off] - specifies whether labels should be drawn as the features for this layer are drawn, or whether they should be cached and drawn after all layers have been drawn. Default is on. Label overlap removal, auto placement etc… are only available when the label cache is active.

  • <position>ur</position> - label offset direction.

    • ur - ↗ up and right (recommended).

    • ul - ↖

    • uc - ↑

    • cl - ←

    • cc - centered

    • cr - →

    • ll - ↙

    • lc - ↓

    • lr - ↘

    • auto

  • <Maxoverlapangle> - ?

5.6.6.5. Some other useful tags

  • MAXGEOWIDTH - Maximum width, in the map’s geographic units, at which this LAYER is drawn. If MAXSCALEDENOM is also specified then MAXSCALEDENOM will be used instead.

  • MINGEOWIDTH - Minimum width, in the map’s geographic units, at which this LAYER is drawn. If MINSCALEDENOM is also specified then MINSCALEDENOM will be used instead.

  • OFFSITE - Sets the color index to treat as transparent for raster layers.

  • OPACITY [integer|alpha] - opacity of the layer

  • SIZEUNITS [feet|inches|kilometers|meters|miles|nauticalmiles|pixels] - Sets the unit of CLASS object SIZE values (default is pixels). Useful for simulating buffering.

  • SYMBOLSCALEDENOM [double] - The scale at which symbols and/or text appear full size. This allows for dynamic scaling of objects based on the scale of the map. If not set then this layer will always appear at the same size. Scaling only takes place within the limits of MINSIZE and MAXSIZE as described above. Scale is given as the denominator of the actual scale fraction, for example for a map at a scale of 1:24,000 use 24000.

  • TYPE [chart|circle|line|point|polygon|raster|query] - Specifies how the data should be drawn. Need not be the same as the feature geometry type. For example polygons or polylines may be drawn as a point layer.
