	Zoom to Active Extent	Zooms to view the full geographic extent of only the currently active layer. top
	Zoom to Last Extent	Zooms to show the previous extent/map view. Note: this is a toggle between the current extent and the previous extent, it does not continue to step backward. top
	Pan	Moves the geographic area shown within the map view in the direction the cursor is dragged across the screen. To drag, position the cursor over the map view, then hold down the mouse button and "drag" the cursor in the desired direction, releasing the mouse button when through. The map will redraw. top

	Pan Right	Shifts the geographic area shown in the map view to the east. top
	Pan Left	Shifts the geographic area shown in the map view to the west. top
	Identify Feature	Click on a feature (only features within the active layer will respond to identify/search tools). Data/information available for the feature selected is shown in the area of the screen beneath the map view. top
	Query	Queries the active layer based on a search constructed from choices offered including field selection, search operators (=, like, gt, etc.), values to search for and boolean operators. Selected feature(s) are highlighted, and data/information available for the feature(s) selected is shown in the area of the screen beneath the map view. top
	Find	Finds a map feature or features within the active layer whose attributes (underlying data) contain a specified string of text. Selected feature(s) are highlighted, and data/information available for the feature(s) selected is shown in the area of the screen beneath the map view. top
	Select by Rectangle	Select active layer features located within a dragged rectangle. Selected feature(s) are highlighted, and data/information available for the feature(s) selected is shown in the area of the screen beneath the map view. The map view will NOT zoom to the rectangle selected. top
	Select by Buffer	Select active layer features located within a specified buffer(distance) around a point. Note: the "point" must be a feature that has already been selected by another tool. Feature(s) selected by the buffer is highlighted. If you choose the "display attributes" option for the buffer tool, then data/information available for the feature(s) selected is shown in the area of the screen beneath the map view. top
	Select by Line/Poly	Select features along a line or within a polygon. To create the line/polygon, click on a starting point (location turns red), then click on successive points along a line or forming corners of a polygon. When finished, choose the complete/select button for either a line or a polygon from the options offered below the map area. Selected feature(s) is highlighted, and data/information available for the feature(s) selected is shown in the area of the screen beneath the map view. The map view will NOT zoom to the area along a line or within a polygon. top
	Measure Distance	Measure distances on the map view by clicking on a beginning location (point turns red) on the map, then either moving the cursor to a second position and noting the distance displayed at the top of the map area, or by clicking on a series of points to create a series of line segments. In the second case, the distance along the current segment is displayed, as well as the total distance along the line. (see set units below to change the units of measure) top
	Set Units of Distance	Choose feet, miles, meters, or kilometers for distances measured/displayed in the map view. Choices are offered below the map when you choose this tool. top
	Clear Selection	Clears currently selected/highlighted features from the map. top
	Print	Prints the map view and legend of your choice to a preformatted map layout. Type a freeform legend into the entry box, submit the form to view the map that is printed in a new window. Use your browser's print function to print the map, then close the preview window to return to the map. top
	Link/URL	Choose this tool, then click on a feature to bring up detailed information or data about the feature selected in a new window. top
	Extract data	To use this tool, zoom to the area of interest, select the features of interest, then click this tool. This tool lets you download a zipped shape file containing visible layers in your selection (with the exception of raster images like wsiearth.tif). Visible non-active layers (like continents) will be downloaded for the entire area shown on the screen - but for the active data layer, only the portions selected (using query, find, or another selection mechanism) will be included in the shapefile. top
	External viewer off	This is a toggle switch. When this icon is showing, results of a search or identify will be returned in the text area below the map. Click on this icon to enable the external viewer, that is to change to opening results in a new window. When you click on this icon, it will change to the icon below. top
