Layers
Features are managed using a series of ordered layers within a style (see Styles).
A layer can be used to display a vector geometry, a raster file, a Web Map Tile Service (WMTS), or text based on a vector geometry.
You can have multiple layers that reference the same class.
Simple vs Thematic Layers
Some layers can be Simple or Thematic types:
-
Simple - Display all features of a class with the same style
-
Thematic - Apply different styles to features based on attribute values. For example if a "landParcel" feature has an attribute that indicates the land type as a numeric code then a Thematic layer can be created to show each land type as a different colour.
-
Rules: You define rules that map attribute values to specific styles. These rules typically match exact values, but can also use operators such as greater than > and it is possible to check if values are null (empty) or not. A Default Rule style can be applied when no rules match the attribute value.
-
Editing Features
Click on a feature layer to display the attributes that can be edited.
You can specify the colours and text that are displayed with features on the map, use background raster or map service layers, and specify which feature types are displayed on the map.
You can use the colour wheel to choose a colour, directly enter RGB values or set opacity.
Vector items
For vector items, you can customise:
-
Fill: The pattern and colour of a feature's Fill. Using a fill pattern on large polygons may have a small impact on performance.
-
Stroke: The pattern and colour of a Stroke. When using a stroke pattern with spaces, the spaces will increase as the line width is increased. You can change the width of a stroke (in pixels) using the Width slider, or by entering a value.
-
Point: The colour and opacity of points.
Text items
For text items, you can change the colour of the text, font family, weight, and size.
Style and Font: Use the colour picker to adjust the text colour, select a font style from the Font Family list, and enter a font weight and size.
Content: Select the text to be displayed for this feature using the Text Property list.
-
Select a value from the string, integer, or enumeration properties,
-
or select
<Fixed Text>to enter the exact text to display.
Re-order or Remove Features
Layers are displayed from the bottom-most layer upwards.
To remove a feature layer from the Style list, select it and click Remove. The feature will no longer be displayed on the map, but can be added back again by selecting Add from the Style page.
Drag and drop feature layers in the Style list to determine in what order specific layers appear on the map.
Copy and Paste Layers
You can copy and paste a Layer from one Style to another. Copy and paste works for all Layer types, including Thematic Layers.
