Defining the County Area

A county area in WSV3 is a designated region within a workspace that represents a specific geographic region. It provides a convenient way to visualize and analyze data associated with that particular county.

To define a county area, follow these steps:

Select the “Counties” layer from the Workspace Explorer.
In the Properties panel, click on the “County Area” tab.
Use the search bar to find the desired county.
Once the county is found, click on the “Add” button to add it to the selected counties list.

Multiple counties can be added to create a multi-county area. The resulting highlighted area will encompass all the counties included in the list.

Here are some additional options available when defining a county area:

Highlight Border: This option adds a border around the county area.
Highlight Color: This option allows you to customize the color of the county area highlight.
Highlight Opacity: This option controls the transparency of the county area highlight.

Creating a New Map Layer

To create a new map layer, follow these steps:

Open the Layer Manager. Click the "Layer Manager" button in the toolbar.
Click the "New Layer" button. This will open the "New Layer" dialog box.
Select the layer type. Choose the type of layer you want to create from the drop-down menu.
Configure the layer settings. The settings you need to configure will vary depending on the layer type you selected. For example, for a feature layer, you will need to specify the data source and the fields that should be displayed on the map.
Click the "Create" button. This will create the new layer and add it to the Layer Manager.

Specifying the Data Source for a Feature Layer

When you create a feature layer, you need to specify the data source that the layer will use. You can choose from the following data sources:

Data Source	Description
Web Feature Service (WFS)	A web service that provides access to geographic data.
Web Map Service (WMS)	A web service that provides access to raster data.
Shapefile	A file-based format for storing geographic data.
Geodatabase	A file-based format for storing geographic data that can be used by ArcGIS products.

Once you have selected a data source, you will need to provide the URL or path to the data. You can also specify the layer name and the fields that should be displayed on the map.

Importing the County Boundary Data

Once you have created a new WSV3 map, you will need to import the county boundary data. This data can be downloaded from the U.S. Census Bureau’s website.

To import the data, follow these steps:

Click on the “Import” tab in the WSV3 toolbar.
Select the “County Boundaries” option from the drop-down menu.

The county boundary data is available in a variety of formats, including shapefiles, KML files, and GeoJSON files.
If you are importing a shapefile, you will need to make sure that the shapefile has a projection that is compatible with WSV3.
You can also import county boundary data from a web service. To do this, click on the “Web Services” tab in the WSV3 toolbar and select the “Add County Boundaries” option.

Troubleshooting:

If you are having trouble importing the county boundary data, make sure that the file is in a compatible format and that the projection is correct.
You can also try restarting WSV3 and importing the data again.

Styling the County Area

The `highlightedCountyAreas` object in the `v3` API allows you to color and outline the area of a county or counties. Many different styling options are available, including customization of the color, line width, opacity, line dash pattern and more. For a reference of all available styling options, see the `highlightedCountyAreas` section of the MapOptions class reference.

Fill Color

The `fillColor` option sets the fill color of the highlighted county area. The color can be specified as a hex string, RGB value, or rgba value (with alpha transparency).

Stroke Color

The `strokeColor` option sets the outline color of the highlighted county area. The color can be specified as a hex string, RGB value, or rgba value (with alpha transparency).

Stroke Opacity

The `strokeOpacity` option sets the opacity of the county area outline. The value ranges from 0 to 1, where 0 is fully transparent and 1 is fully opaque.

Stroke Weight

The `strokeWeight` option sets the width of the county area outline in pixels. A larger value will result in a thicker outline.

Stroke Dash Array

The `strokeDashArray` option sets the dash pattern of the county area outline. The array contains a series of numbers, where the first number is the length of the dash and the second number is the length of the space between dashes. For example, an array of `[5, 5]` would create a dashed line pattern. To create a dotted line pattern, use an array of `[1, 1]`. Dash patterns can be combined to create more complex patterns.

Dash Pattern	Example
`[5, 5]`	————
`[1, 1]`	· · · · ·
`[5, 5, 5, 5]`	——— ————
`[1, 5, 1, 5]`	· — · — ·
