gmn status v2

Release Note V2

In this major new release:
  1. The country selector is moved to the top left of the right hand panel
  2. A new multi-country view is enabled by selecting "ALL Countries". In mutli country mode the camera panels which are displayed on the right hand side is determined by the boundaries of the map currently displayed. As the map is moved and zoomed the cameras panels will update.
  3. Effective caching of all data to improve performance and minimize the need to refresh the page.
  4. Automatic 60 min background display refresh which makes the page suitable for a static display panel.
  5. A new feature to analyze the field of view coverage at a selected altitude over the geography of the displayed map. Cameras outside the boundaries of the displayed map are included. This will help identify those geographies not well covered and holes in existing coverage.
  6. A new ability to identify those cameras which have a view of an arbitrary point of interest (identified by a marker - double click to add) at a selected altitude. Once the location of an event is known this function will help identify further cameras that may have captured the event.
  7. An ability to display FOV's associated with all camera panels currently displayed.
The detailed notes below have been updated to reflect these changes and other minor enhancements.

Please report any issues.

Overview

The primary purpose of this facility is to provide an overview of the Global Meteor Network's status by country and fast access to individual cameras and sites.

The design expects a large screen (typically a PC monitor). It does not work well on small screens.

All displayed data is extracted from active weblogs as the page loads. There is no delay. Data will refresh automatically hourly.

When first opened on a new device your external IP address is resolved to determine what country to display. A dropdown list box located at the top left of the right panel can be used to select an alternate country if required. The most recently viewed country should be sticky between browser sessions on the same device.

If the page is envoked with a country parameter this will always take precedence and become the new default.
i.e. https://globalmeteornetwork.org/status/?country=AU

The left hand side of the screen provides a map which identifies the public location (blurred for privacy) and colour coded state of each camera. The leg on the camera icon provides an indication of the direction the camera is pointing.

The selected country determines what camera panels are initially displayed on the right side. On start the map automatically pans and zooms to cover all the known locations of cameras associated with the selected country.

Most active elements provide help when "hovered" over with a mouse.

Once the initial country is loaded the country selection may be changed to "ALL Countries". In this mode the selection of camera panels displayed on the right is determined by the bounds of the map. The camera panels displayed will dynamically update as the map is panned and zoomed.

Multiple cameras on a site are stacked and will reveal on zoom-in. Clicking a camera icon provides a menu with options to open the camera's weblog, archive, latest capture image, latest timelapse, and display 25/70/100km field of views.

Double click on the map to drop a marker which on hover displays the latitude and longtitude of that point. Zoom map in (using mouse roller or +/- controls) before double clicking to ensure accurate placement. Double click a marker to remove.

The right hand side initially displays each camera's latest captured image as a thumbnail, except UK, together with options similar to the map camera marker. Cameras are initially grouped by region, and then ordered by camera ID - except in the UK where there are no groups. Regions are sorted by name except some countries sort North/South. Regions are allocated automatically using an on-line service.

The top line Sort option allows the camera panel order to be changed. The North/South and West/East Region sort options find the most westerly or northerly camera in each region to determine the order.

The top line Mode option controls what is displayed in each camera panel. The Captured image can be enlarged and UK users can enable thumbnails and more here.

The status color bar on the top line is dual purpose. On hover it explains the meaning each status color. The check boxes allow the displayed camera panels to be subsetted. For example, unchecking the blue checkbox will cause camera panels in "waiting for data" status to be removed from the display. Alternatively, clear all the check except orange and only sites with camera connection issues will be displayed.

Entering text in the Text Filter input box and pressing the return key causes cameras that don't include the entered text in their ID's or descriptions (.config details) to be excluded from the display.

Once a marker is in place on the map (double click to add) the "Marker Filter" (top line of camera pannels) will enable. Selecting a filter option will subset the cameras panels displayed to those which have a field of view that extends over the marker. If an event point of intrest is known this facility will help identiify those cameras that might have "seen" the event. Return the option selection to "None" to enable the display of all camera panels.

Three field of view buttons (25km, 70km, 100km) on the top line of the right hand panel add the respective FOV's to the map for ALL camera panels currently selected. The "X" button will clear all Fov's from the map.

The "FOV Analysis" button runs an analysis of the geography displayed in the map to determine the coverage provided by known cameras. Points that meet coverage requirements are marked. The adjacent "X" button clears the markers from the map. In determining coverage the process considers the coverage provided by ALL cameras within in the maximum distance (default 400km) - not just those visible on the map.
Warning - this process can require significant bandwidth (to retrieve a large number of FOV polygons) and may run for minutes.

A "+" following a camera code on the bottom line of the camera panel indicates a multi-camera site.

Clicking the 3 angle symbols under each region name adds 25, 70 & 100km FOV for all cameras in that region to the map.

The divider between the left and right hand sides can be dragged to change the allocation of the screen between map and site thumbnails. This functionality works well on a pc with a mouse but not consistently in a touch environment (such as a phone or tablet).

The drop down list box in the heading above the map determines the observation date of the images displayed. The default is Latest. If the appropropriate indexes exist previous night oberservation datasets drawn from the archive can be selected. When archive datasets are selected only cameras that succesfully uploaded capured images will be displayed.
Note - Archival datasets are not currently supported in All Country mode.

I hope this proves useful. Please provide any feedback you have in the discussion group. I'll look at all suggestions.
