Visualizing Meteorites

Visualizing Meteorites

This visualization is made to bring new insights to the fields of meteoritics. It brings data of little more than 500 years. It is most of all a learning tool, that can be used to see geographical patterns on meteorite finds and falls that may not be obvious in first sight.

Its functionalities are:

- the window on the map, that can be resized by the corners and replaced by dragging. This window will define which meteorites will be shown in the graphs below the map. This way we can see density by area.

- the sliders: Year sliders, to set time frames, Mass slider to see only small or larger meteorites and density sliders, that increases transparency on meteorites so we can know their concentrations by area.

- the toggle buttons, that turn on and off fell meteorites, found meteorites and the need or not to see their mass.

- the graphs, that show how many meteorites are in the area defined by the window and which percentages they represent from the total as well as the ratio of fell/found meteorites.

Using the density tool, it's possible to perceive that most meteorite finds are in desert areas (Sahara, Chile, Oman etc). Dragging the window through these areas, one may find out that most meteorite finds were made in deserts in Antarctica.

One may also notice, using the toggle buttons, that meteorite falls are seen in densely populated areas, such as Europe and India.

Using the time slider and observing the graph, it's possible to see the rise of meteoritics in the 20th century, when finds quickly surpassed falls, which had not been true for hundreds of years.
