Show the local time for the position under the cross hairs.

• Add a 'Show local time' setting
• Apply time zone offset extracted from Time Zones layer

The Day/Night image is no longer being displayed

Improve the layer list UI in the layer manager.

• Display the count next to the category so user can have insight into the contents without having to expand the layer manager.
• Use "badges" instead of buttons for show/hide, configuration, and zoom.
• Add feedback to show the currently selected layer.

• The [R] key should reset the view
• The reset button associated with the Location Widget should reset the view

It appears the USGS has renamed/renumbered their layer names (again).

The header tab buttons (Layers, Markers, etc.) should toggle their respective views. Currently the behavior is only to show the view. The suggested behavior would toggle between show and hide.

Add the Map Icons Collection into the marker palette.

Add the ability to easily toggle the Day/Night & Atmosphere on/off. In nighttime regions the Day/Night layer occludes the underlying data--this must be made easy to defeat this issue.

• This feature must be easy to use
• The utility of this feature should be easy to discover

Allow time series layers to be controlled by the date/time widget.

Centering the globe on a pole causes the browser to freeze. The browser tab must be closed to recover.

At startup, the following error repeats 256 times in the before being suppressed by Chrome:

[.CommandBufferContext.Offscreen-MainThread-04553D80]RENDER WARNING: there is no texture bound to the unit 0 (13:39:26:381 | warning, rendering)
  at root/index.html
WebGL: too many errors, no more errors will be reported to the console for this context. (13:39:26:648 | warning, rendering)
  at root/index.html

In FireFox, screen image are clipped when you zoom in on the globe. In the following screenshot, note the View Controls and the Location and Time widgets have been clipped by a circular region. The circular region grows as you zoom in.

Note: This issue occurs also in the WebWorldWind SDK's Explorer app/demo.

Add an "About" tab to the Info panel that displays open-source credits, links and other useful information about the Explorer.

Add an option to show the user's location. This could be a optional, persistent marker in the Marker view or a setting.

It appears that marker altitudes are absolute. I.e., a 0 altitude is at 0 MSL and may be below the terrain.

Allow the user to select the background/effects.

Candidates:

• Slate
• Black
• Starfield
• Atmosphere

Add a Location tab that displays relevant information about the current reticule (crosshairs) location and the last queried (right-click) location.

Candidates:

• Lat/Lon and other coordinate systems
• Elevation (ft and meters)
• Administrative places
• Sunrise/Sunset

Tilting past 66 degrees on a large canvas causes severe performance lags when attempt to pan the view. The problem disappears when I move towards nadir or shrink the size of the canvas.

Add vis.js, a dynamic, browser based visualization library.

The library is designed to be easy to use, to handle large amounts of dynamic data, and to enable manipulation of and interaction with the data. The library consists of the components DataSet, Timeline, Network, Graph2d and Graph3d.

The button next to the time zone layer does not seem to do anything, and the one next to it displays an opacity slider that also does not do anything. I also believe that adding the current time in each time zone as the user hovers over it would be a useful enhancement.

Add a help page that can be displayed in separate browser window. The help system should be accessible from a "?" help button on the main menu as well as from "i" info buttons elsewhere in the Explorer.

• Establish documentation website linked to branding
• Tooltips

Dragging the globe with a mouse stopped working after switching to worldwind.js compiled from WebWorldWind develop branch 06-Feb-2017. I don't know if this is a due to a change in the library or a change in the environment, e.g., new browser versions.

It is not possible to scroll the layer lists on a mobile device while the dragger is active.

Expand the functionality of the Layer settings dialog to show the layer's legend.

(As alternative, consider adding a Layer tab to the Info panel that shows the selected layer's legend and all the available metadata.)

Markers that are farther away should be smaller than markers that are closer.

Add an Output panel below the Globe panel to display ancillary information.

• Output panel should be resizeable
• Output panel should be collapsible

Use the Split.js library to create a splitter between the Globe and Output panels.

Change the behavior from sin / exponential value to a simple +/- 24 hours. The new repeat behavior on the fast foward/backward buttons now provides the ability to advance the days.

The camera remains at nadir when a bookmark URL is loaded from a tilted view.

Use the Split.js library to make the size of the left side panel adjustable.

• Include a button for collapsing the side panel.
• Include behavior to expand a collapsed side panel when it corresponding navbar button is clicked.

Clicking the layer category headers should toggle the collapse/expand the layer list.

Since the panels and can be opened by the navbar header buttons, the splitter bar (with grabber) no longer needs to be displayed.

Time controls should be moved to the bottom of the screen.

Provide the capability to add ad hoc layers to the globe
Include in the design, planned support for:

• WMS Layers
• WMTS Layers
• Shapefiles
• KML
• GeoTiffs
• Collada

Ensure the URL and the copy functions are compatible on all browsers.

The green tick mark is hard to see on many backgrounds.

Recommend changing to red.

It is not very clear to a new user what the circular widgets on the bottom left and right are for, so I would recommend adding tool tips or something similar that can explain what everything is when the user hovers over them (for example, that the times on the bottom left are sunset and sunrise, what the little sun icon represents, and even that the forward and backward buttons change the time of day and the date).

The initial sort order is not intuitive, low resolutions layers on top of higher resolution layers.

Navigating around the north and south poles yields "invalid date" on the bottom left widget instead of the sunrise and sunset times. Also, navigating all the way to the very north or the very south will cause the webpage to crash and become unresponsive.

Implement an XML parser for point weather forecasts from the National Weather Service (NWS) National Digital Forecast Database (NDFD). This parser should replace the dependency on the WMT REST server and communicate directly with the NDFD service.

Add a single/multi layer mode option to base maps. When in single layer mode, clicking a new layer will automatically disable the existing layer. This saves bandwidth.

Suggest adding a checkbox for multi-layer mode in the category header.

In Chrome, the page size is larger than the screen size, and is truncated at the bottom, as can be seen in the following screenshot.

Bottom of page is truncated

When loading an application in Chrome I get this error 256 times:
[.Offscreen-For-WebGL-000001A2056308A0]RENDER WARNING: there is no texture bound to the unit 0
WebGL: too many errors, no more errors will be reported to the console for this context.

I've seen similar issues, but none with the same error code (000001A2056308A0) as mine.

Add the D3.js Data Driven Documents library for use in the Output panel.

From the D3 website:

D3 allows you to bind arbitrary data to a Document Object Model (DOM), and then apply data-driven transformations to the document. For example, you can use D3 to generate an HTML table from an array of numbers. Or, use the same data to create an interactive SVG bar chart with smooth transitions and interaction.

I am unable to drop markers on the globe using a touchscreen interface.

Update to WebWW v0.9.0

Add support for point weather forecasts from the National Weather Service (NWS)

• Add ability to place Weather Scouts on Globe. Weather scouts are placemarks with weather forecast data.
• Add a Weather tab to manage Weather Scouts
• Display weather data from selected Weather Scout in Output panel

The name "World Wind Explorer" can be misconstrued as an app for exploring the world's winds. It's not readily apparent in this context that "World Wind" is a NASA organization. The application/project should be rebranded such that the organization and name are distinguishable. Ideas:

• WorldWind Explorer : concatenate "World Wind"
• NASA WorldWind Explorer : add NASA to concatenated WorldWind
• NASA WorldWind Explorer : leverage typography / colors / logos

Also, include credits to third party open-source projects in the README.
