The following eMaps help describes how to use ADEQ's public interactive web mapping application.
The eMaps tutorials describe uses of eMaps that better demonstrate what can be done with it and why you would want to do it.


Map Navigation

At the upper-left corner of the map are two pairs of map navigation buttons.

Plus (+) button: Click to zoom the map in (or scroll the mouse wheel forward). You can draw a zoom in rectangle by pressing the Shift key while dragging the mouse (except when the map tool is Select Features).

Minus (-) button: Click to zoom the map out (or scroll the mouse wheel back).

Home button: Click to view the entire state of Arizona.

Question mark (?) button: Click to view this help.

To pan the map, click and drag it in your direction of interest (except when the map tool is Zoom In, Zoom Out, or Select Features). Or click one of the eight arrow buttons in the corners and along the edges of the map.


Navigation Keys

Some of the keyboard keys can be used to pan and zoom the map while the mouse is over the map and the current map tool is Pan Map.

Hold down the key until the desired pan distance or zoom level is achieved. The keys work independently of the current map tool.

Menu
tool menu


The application menu is organized into four top-level menus; Map Tool, Navigation, Features, and Information. The menu items come in three types; map tool, entry form, and immediate action (the colors are for illustrative purposes, the menu item text is not actually colored). A map tool sets the map behavior that occurs when clicking or dragging the map. An entry form performs an action after entering the desired criteria and clicking the form's command button. An immediate action occurs at the time the menu item is clicked.

The icon and drop-down menu on the left of the top-level menus indicates the current map tool. This is the action that will occur when the map is clicked or dragged. The map tool can be selected in the Map Tool drop-down menu or in one of the other three top-level menus. The current map tool stays in effect until another map tool is clicked, that is, entry form and action menu items can be clicked without affecting the map tool.

The following feature menu items act upon the active layer set in the Table of Contents by clicking on the layer name (which then becomes bold): The top-level menu item's background changes to blue while hovering over the item but requires one of the top-level menu items to be clicked to actually show its drop-down menu. After clicking one of the top-level menu items, hovering over other top-level menu items will automatically show their respective drop-down menus. This behavior continues until either a drop-down menu item is clicked or a top-level menu item is clicked returning the menu to its original behavior.


Map Tool The Map Tool top-level menu provides the ability to set the current map tool.

The Map Tool top-level menu sets the current map tool as described above. The name of the menu, and the icon to the left of it, changes to indicate the current map tool.

The following menu items in the Map Tool menu are described below in the Navigation, Features, and Information menus since they are duplicates of the map tools spread among the other top-level menus: Up

Zoom Out Map Tool Show greater map area, less detail.
Draw a rectangle by clicking and holding the left mouse button down on the map at one corner of the rectangle and dragging the mouse to the other corner of the rectangle, and releasing the mouse button.
