The web mapping interface has been designed to provide you with a simple and intuitive web mapping experience that is modeled after popular consumer based web mapping applications. This includes a buttonless interface, seamless panning, scroll-wheel zooming and intuitive search and mark-up tools.
The Web Mapping Application page has four main parts:
To switch between the Map Layers and Results, click on the tab with the name of the function you want to access. You can resize the console area by the divider between the Console and the Map. You can also click on the arrow button on the far right of the console, which will collapse the entire console. This allows more room to view either area as you work.
You can use a mouse to perform nearly all navigation functions on the map:
The web mapping interface allows you to easily access commonly used background data. This includes roads, aerial photos flown at various times, and topography data. Click on the available Background Data layers to quickly toggle between a background dataset. When you choose a background dataset, it will always be available and the map layers you turn off or on in the map layer list will be displayed on top of the background. You can also toggle between two background datasets using the swipe tool, which can be useful to detect changes between two aerial photo flights.
Each map available in the application has a number of map layers available with it. These map layers have names, legends and may be grouped together. You can turn off and on the map layer by clicking on the checkbox beside the map layer. Due to the size or content of the data, some data layers may not be available at all scales. If a map layer is grayed out, then the layer is not available for display at the current zoom level – if you zoom in on the map, the map layer will become available.
The transparency of the map layers can also be toggled with the transparency slider bar at the bottom on the map layer list.
Some tools, such as the Measure window and the Identify window, may be moved around the page. You can arrange these elements to suit your own work. To reposition tools, click on the arrow pointing to the right and the tool will undock. After undocking the tool, click and hold the left mouse button on the title bar of the element and move to the desired location. To dock the tool back to the console, click the arrow that will now be pointing to the left. To minimize the tool on the interface without closing it, click on the dash symbol in the title bar of the element. Close a tool by clicking the close button it its upper right corner. All windows can be re-opened by clicking on the tool name in the toolbar menu.
You can continue to navigate on the map – zoom, pan, and change the extent of the map – while using any of the tools. This means that you can measure, markup, print, and user other tools and still change your current extent on the map. You can also right-click on the map at any time to bring up the option to Export the map or to insert a pushpin on the map. Choosing the Export option will open the export menu. Choosing the Pushpin option will insert a pushpin on the map and will send the pushpin to the Markup tool.
Identify: The Identify tool can be used to view attributes about map features by clicking on the map or clicking the Buffer, Polygon or Point buttons in the Identify tool window and drawing a sketch on the map. When using the Polygon tool, each click on the map will place a vertex (corner) and allow users to define the shape of the area. The following functionality is available in the Identify tool:
Using Results: Once features have been identified on the map, you can investigate the results using the results tab on the Console. The layer name and number of returned records will be provided.
Measure: The measure tool can be used to measure user defined distances and areas in the map panel by clicking on the measure tool. The following functionality is available in the Measure tool. To measure linear distances, click on the map to start sketching a line. To measure an area, click on the Draw Shape button in the Measure tool window and start sketching.
Markup: The Markup tool is used to create geographically referenced and/or feature-linked graphics and text which can be displayed on the map at varying scales. Markup items are a permanent part of the current map session and will be visible when you print or export a map. To use the tool, select from custom polygon, line, circle, rectangle, text, and arrow markup types and then draw the markup on the map.
You can control markup outline / fill color and transparency, line width as well as modify graphics and text after it is created. By default, the application provides a name using the shape type chosen by the end user but you can rename the mark up and click on the Save button to save it in your current map session. You can also enter a description for the mark-up which will be available whenever you click on the mark-up item on the map in a new bubble window:
Once you have created mark-up on the map, you can click on a markup item to see its name, description and to edit its attributes. You can also turn off and on individual markup items using the checkboxes in the markup items list. The pencil beside each item allows you to edit the item and the trashcan beside each item allows you to delete markup.
ZoomTo XY: The Zoom to XY tool is used to jump to a specific map location based on a known set of map coordinates. Users will click on the Zoom to XY tool and enter the coordinate values as Decimal Degrees, Degrees/Minutes/Seconds, UTM coordinates, or native map units in the appropriate boxes. Clicking the Go To button will re-center the map on that location, place a pushpin on the map, and save the pushpin into the map markup.
Swipe: The Swipe tool allows you to quickly toggle between two background layers. Choose the background datasets you want to “swipe” from the list on the menu and, using your mouse, drag from left to right to toggle the background layers. This tool is useful to determining changes that may be visible on two background datasets. If you press the ctrl key while the Swipe tool is open, the normal navigation tools will be available. This allows you to pan and zoom on the map and quickly switch back to the swipe tool.
Google and Microsoft Tools: The “View In” menu gives you the choice to view the currently displayed mapping area in either Google Maps or Microsoft Bing Maps. For Google Maps, you can choose to view in Street, Aerial Hybrid, or Aerials Only mode. For Microsoft Bing Maps, you can choose to view in Street, Aerial Hybrid, Aerials Only, or Bird’s Eye mode. The Google and Microsoft Bing Maps views will be launched in a new browser window, and you can change to any viewing mode once the new window has opened.
|MapViewer Aerial||Google Maps – Aerial Hybrid|
|Bing (Local Live) - Streets||Bing (Local Live) – Bird’s Eye|
The Google Maps Controller tool will bring up a new panel that will allow you to view your current mapping area in Google Maps StreetView. After the tool is launched, you will also see an approximate field of view representation on the map which corresponds to the current orientation in Google Maps StreetView. As you change the orientation in StreetView, the field of view representation on the map will automatically update.
Print: The Export / Print tool generates a printable export of the current map. Click on the Export/Print button on the toolbar, choose the map format. Image formats will be provided as a simple image in a new browser pop-up window, that can then be exported by right-clicking on the Image and choosing the Save As… option. If you choose not to scale the image to fit to the current map window, the software will show an “Export Area” on the map.
Bookmarks: The Bookmark tool allows you to quickly zoom to specific locations on the map. Click on the named bookmark that you want to use and the map will zoom to that bookmark extent.
Available Maps: Depending on your security access on the application, more than one map may be available to use. To access other maps on the application, choose a map service from the list of available maps. This will reset your map session so that any active tools will be reset as well, including map markups. The layers, bookmarks, and other content of the map may change significantly from one map to another.
System Requirements: The web mapping application is designed to work with all modern web browsers but is optimized for Internet Explorer 6+ and Firefox 1.5+.
