Vector GIS Layers

Basic Options with GIS Files in waterRIDE

The basic tab (shown below), allows a variety of options to be modified and customised, specifically colours, symbols, line styles, and region shades.

Symbols and Lines

The user can change the colour of the symbol and lines for a layer by clicking in the coloured panel beside ‘Symbol:’ or ‘Line:’ and selecting the desired colour from the palette.  Clicking the up and down arrows in the ‘Size’ control box changes the size of the symbol or line thickness in the main viewing window. The symbol style options can be changed using the drop down ‘Style’ box. This allows the user to select what type of symbol is to be used in the current view for that specific layer. By selecting ‘none’ in this box will prevent the symbols or lines from being displayed in the viewing window.

The line style option can be changed using the drop down 'Style' box. This allows the user to select what type of line is to be used. Selecting ‘none’ in this box will prevent the lines from being displayed in the viewing window.

Region Settings

The ‘Region’ settings allow the user to control the outline, ‘fill’ or ‘hatching’ of regions (polygons) in the layer.  The region outline colour is controlled by clicking in the coloured panel beside ‘Line:’ and selecting the desired colour from the palette. The large drop down box allows the user to choose what fill style will be displayed inside the regions of a layer, such as solid colour or hatched in various ways.  Selecting ‘<clear>’ will remove any fill from regions present in the layer.

The colour panels beside ‘Region:’ and ‘BG:’ are used to control the colour of the solid fill or hatching in the region. The upper colour panel found next to ‘Region:’ controls the colour of solid fill or hatching (if present).  When hatching is used, the ‘BG:’ (background) option can be used by ticking the box and using the colour panel to change the colour used for the background fill.

Colours

In order to change the colour of either regions, lines or symbols the colour tab needs to be clicked beside the respective tool. This brings up a colour selection dialog, which allows the user to select from typical colours or to customise a colour for use in the project.

Default Options

The default options are set when you modify a GIS component and leave the 'Set for' default values. When you want to use the default values click on the 'Use Default Values' button which will set the Symbol, Line and Region styles as well as their respective colours to the defaults setting previously set. Alternatively, the layer properties can be applied to the current view only. This allows a layer to be displayed differently in different views.

Layer Display Limits

The ‘layer display limits’ specify the limits of visibility of the layer in terms of view scale. These allow the developer to specify a range of scales at which a layer is visible to the user. This can be useful if a view contains many layers that are not necessary in a zoomed-out view, but become important as the user zooms into the view (such as an image of a suburb on a map of a country). The current scale is shown which can be used as a guide to set the visibility scales for the layer. The ‘zoom in’ limit is the limit at which any further zooming in will render the layer invisible. The ‘zoom out’ layer is limit at which any further zooming out will render the layer invisible. The Reset buttons will reset the limits so the layer can be seen at all zoom levels.
