Layer Settings

This sets the layer options for the various layers in the Map Windows. Not all layer options are currently exposed yet. However, settings for many layers are minimal. These properties are inherited as a block. Once a property is changed for the map or session, the map or session maintains its own copy of all these properties from that point forward. The table below provides definitions for the features available in the layer settings tab.

Group	Layer Setting	Definition
Internet Map Settings	Transparency (0-100)	Used to set the transparency level of the maps in the event that this layer is not the first layer drawn.
	Data Source	This sets the data source to use for the maps.

Annotation Settings	Automatic Annotation Saving	When checked, this will assure annotations are automatically saved as the edits are occurring. When not checked, saving annotation edits requires right-clicking on the correct file in the active annotations node via the Project Explorer pane and selecting 'Save File' from the context menu for the node.

Contour Settings	Smooth Contours	Sets whether the contours should be smoothed or not. Smoothed contours look nicer but draw much slower.
	Fillet Size (0-100)	Sets the size of the fillet to smooth the contour with. Normal set to 100 for the best look.
	Fillet Smoothness	The number of points to draw a fillet with. Using more points will result in smoother fillet appearance and increased draw times.

Polygon/Basin Averages Settings	Ignore Palette Transparency	If set, the basin averages use the palette color but draw them opaque.
	Ignore Palette Fill Pattern	If set, the basin averages ignore any palette fill patterns and just use the shade color.
	Use solid color under text	If set, uses the palette color as an opaque color under the text.
	Display Polygon Names	If set, the name of the polygon is displayed in the center of the polygon. The name is from the shapefile .dbf file LOCATION column.
	Display Polygon Averages	If set, the polygon average is displayed in the appropriate units in the center of the polygon.
	Display Polygon Volume Equivalents	If set, the volume equivalents are computed for the basin. This is only done if the program can convert the measurements units and average to a known resultant unit type.
	Labeling font	Shows the current font in use. Button instantiates a standard font selection dialog.
	Use Specified Font Color	Select this to override using the palette to set the font colors for the labels. Normally the labeling font color is computed from the palette/scale in use.
	Polygon Average Font Color	This is the color to use for the labeling font if the font color is specified.
	Polygon Draw Order	This can be set to either 'Sequentially as Encountered' or 'By Defined Attribute Type'.
	Use Line Types as Polygons	If set, then in addition to giving a list of polygon types that can be used for computations, it also allows the use of line types for polygon type computations. Normally this is set off because the shapefile has the necessary objects identified as polygons.
	Draw simplified polygons	If set, polygon average layer will draw the simplified polygons (used in computations), based on the simplification thresholds in the global settings.
	Show Averages for <Attribute>	There will be on one of these for each polygon attribute type defined in the schema being used plus one named 'Polygons' for unknown type polygons. In the event that the option to use line types for polygons is selected, the enumeration will also include all the line types for the schema.

Tin Measurement Settings	Ignore Background Label Color	When checked, the label background color is not used. When un-checked the label background color is used. When many labels are present and overlap, leaving this unchecked will assure that the topmost TIN measurement settings can be read at the expense of obscuring earlier rendered data in the Map Window.
	Show Gage Names	Check this to show the names of the gages at their locations.
	Show Gage Amount	Check this to show the gage measurements
	Label Color Follows Scale	If this is checked the color of the label text matches the corresponding color from the specified color palette for the measurement value. This is similar to computing a contour color to use for the contour layer. If unchecked, the label is colored using the applicable background and foreground colors.
	Labeling Font	The font to use to label point.
	Gage Label Foreground Color	The text color to use when not basing the colors on the measurement value.
	Gage Label Background Color	The text background color to use when not basing the colors on the measurement value and the 'Ignore background label color' is not checked. It results in a small box under the text label to improve readability although it may obscure earlier rendered data in the Map Window.

Tin Grid Settings	Show Sparse Search Grids	Primarily used for debugging, this option shows the layered sparse search TINs which are used to improve program performance. There are no options for setting the color attributes of the sparse search grids.
	Missing Value Color	The color to use for TIN grids triangles that are undefined or out of bounds.
	Line Color	The color to use for TIN grid triangles that have valid measurement data defined.

Map Layer settings	Ignore the Visibility Threshold	Some map attributes have visibility thresholds defined which limit the amount of data displayed at various zoom levels within the program. For example, if viewing a map showing the continental U.S., an active map that shows city streets would likely create map clutter and convey very little. As the image is zoomed, perhaps to the city limits, the city streets become visible. Selecting this option disables the threshold parameters and draws everything within the view.
