2. Habitat Analysis Interface Functionality

The habitat analysis interface is composed of three sections: a menu interface on the top, a map section showing data layers and legends, and an info panel on the right.

interface

The menu interface includes a button menu and a tool menu for navigating map, printing map, identifying data layer attribute information, and performing habitat analysis. The button menu contains buttons and is placed on the top row, and the tool menu contains tools and is placed on the second row. 

A button executes its function immediately when it is clicked. Click on a tool only activates it. A tool requires user interaction with the map before it executes its function.  It remains active until another tool is activated. While a tool is active, each click over the map display triggers its function. An active tool appears the icon being pressed in such as the 'zoom in' tool on the image above.

The info panel has two links on the top: Interface Help and Advanced Options. Click on the Interface Help link to display the online help page on the buttons and tools. The Advanced Options link allows adding other land cover and road network data layers to the current map display.

Navigate Map:

Click on the button to return to the previous viewing extent.
If you have returned to a previous extent, click on the button to go forward again.
Click on the button to go back to the initial map extent you saw when you first accessed the map.
Click on the button to refresh the current map from the browser cache. Useful if the current map was not drawn correctly. This button does not retrieve the map from the map server again.
Click on the button to stop retrieving the current map if you change your mind and do not want to wait or if you think something went wrong. The button appears gray when the map retrieving process is stopped.
Click on a location or define a box to enlarge the map features. It will appear that the map is moving closer.
Click on a location or define a box to reduce the map features. It will appear that the map is moving further away.
Drag the map or click on a new location to re-position the map display.

Print Map:

Click on the button to generate a map for printing out or saving to local disk. It pops up a dialog window for entering map title. The the printable map is displayed on a separate window with the current map display and legend.

Identify a Data Layer's Attribute Information:

To find out attribute information of a specific data layer for a specific location: 

  • Click on the tool to activate it if it is not the active tool;
  • Click on a location of your interest on the map display. If more than one data layers are visible on the maps, a data layer list will be displayed. Select a data layer from the list for the identifying operation.

  • The attribute information of the selected data layer on the location of interest will be displayed on the info panel.

Perform Habitat Analysis

  • Activate the tool if it is not the current active tool;
  • Draw an outline on the map display to define the study area. Double click the last point to complete the outline. If the map display is too far away to define your study area, zoom the map closer using the tool (see Navigate Map section for help on the Zoom In tool).
  • Select analysis parameters including land cover layer, grid cell size and modeling season from the Habitat Analysis Parameters dialog window. The dialog window pops up automatically once the study area outline is completed. 
    When the Missouri Statewide Land Cover is used for habitat analysis, the grid cell size options are 150, 100, 50 and 30 meters and only winter habitat can be estimated. Otherwise, the grid cell options are 100, 50, 30 and 10 meters. And the modeling season options include winter, summer and overall.

  • Click the OK button the dialog window to complete the selection of habitat analysis parameters. If the estimated process time exceeds 1-minute, the requested analysis will not be performed. The info panel will display a message. Otherwise, the estimated habitat result will be added to the map display.

Create a New Land Cover Data Layer

If you start the habitat analysis interface by choosing to create a new land cover data layer, the interface will include additional buttons and tools.

The functionality of the buttons and tools for generating new land cover data layer are described below:

Click on the button to create a new land cover data layer for digitizing fields.
Click on the button to select a different land cover layer for editing. It is useful for switching between editable land cover data layers if you have created more than one land cover layers to the map.
Click on the button to select and save user-created land cover data layer(s) to local drive.
Add a rectangle shaped land cover unit to the editing land cover data layer by drawing a rectangle on the map.
Add a circular shaped land cover unit to the editing land cover data layer by drawing a circle on the map.
Add an irregular shaped land cover unit to the editing land cover data layer by drawing a polygon on the map. Double click to complete the polygon drawing.
Split a land cover unit into two units by drawing a line going through the unit.
Append an new land cover unit next to an existing land cover unit polygon by drawing the additional boundary line.
Click on a land cover unit to select it and enter land cover attribute information.
Click on a land cover unit to delete it from the editing land cover data layer.
