  1. < 100, title: Jolly Jellyfish
  2. 100+, title: Staggering Seahorse
  3. 250+, title: Tailspin Turtle
  4. 500+, title: Dorky Dolphin
  5. 1000+, title: Wandering Whale
  6. 2500+, title: Mesmerizing Mermaid

The map of observations

EOW Map showing data points in water bodies with information about users and a date reverse sorted list of measurements

EOW Map showing data points in water bodies with information about users and a date reverse sorted list of measurements

The normal Eye On Water map view shows the data points in the location they were taken. In the sidebar on the right, the initial view shows recent measurements and the list of active users.

  • Clicking on a data point (which may include multiple other data points that sit at the same location) pulls up information in the sidebar about that / those point(s).

    Details for one or more data point.

  • Clicking on a pie chart shows a pie chart for all data points within the water body and a graph of the FU values over time.
  • Clicking on the close cross (x) next to the measurement details and timeline returns to the initial view
  • Clicking on a recent measurement zooms in / out the map to show the measurement
  • Clicking on an active user will zoom in / out to show the measurements taken by the selected user
  • On the top-right of the map is the layer-switcher menu. There is an option to show error margins. The error margin is 4 points around each EOW data point to allow for errors in the location of the data point, such as from GPS on the device. This option shows these.
  • Underneath that is to show Lines for Waterbody Features – this shows lines that link the data points to the waterbody pie chart. This is here more for debug purposes, but is again quite interesting.
  • And underneath that is EOW Points Box to show the bounding boxes around clusters of data points. This is debug and somewhat interesting though it doesn’t help understand the map. The clusters are arbitrary bases on some algorithm and they are used to limit the number of waterbodies searched to find data points in
  • In the middle and the bottom are all the layers that make up the map. All but the very ‘bottom’ one can be turned on and off.
