Mobile Devices

The screen size of a mobile device is limited. To work with this limited space the app resizes the widgets and toolbar to fit the screen. Sometimes rotating the device 90 degrees will make the app easier to use. There is no preferred device orientation.

The two differences in the app with mobile devices and smaller screens are widget size button and a more button on the toolbar. The widget size button either maximizes the widget to the full screen or makes is smaller. When smaller, both the map and widget can be seen at the same time. See also Map Widgets for more info on how to use the map widgets.

The more button opens a window that is used to select other widgets that are hidden.

Depending on the application there may be different widgets shown. Select a widget from the panel to use it.


Pop-ups show information from each layer in the map, such as land owner, zoning, commission district, or water line. They dispaly charts, images, and links to other resources.

The top right corner of the popup has a maximize and close buttons. The maximize button opens the popup to the full view of the map. This is helpful when there is lots of information in the popup. The close button will close the popup window. When the popup widget is maximized, the restore and close buttons are displayed in the top left corner of the popup. The restore button shrinks the popup window back to its normal size. When the map is searching for popup information, the spinner will display in the top left corner

When there are multple items returned by the popup, scroll arrows are shown at the top of the widget. The first item shows the total number of items found and an arrow pointing right.

After the first item, the current item page and two arrows will be shown.

Links to other data is shown as a regular hyperlink or or a link icon in the bottom of the widget.
