In the days before weather forecasts,
people would predict the weather
based on the color of the sky,
the direction of the wind, the behavior of animals,
and other natural phenomena.

In the modern-day world,
thanks to advancements in technology,
weather forecasts have become remarkably accurate,
and the information they provide
has become a key part of our daily lives.

But in exchange, we are slowly losing
our ability to notice changes
in the natural world and becoming increasingly
reliant on information.

Now, as typhoons, torrential rain,
and global warming become harder to ignore,
we need to take time to reflect on the weather,
and confront environmental issues.
SKYPEDIA is an app that has been developed
to help us face these issues.

SKYPEDIA generates illustrations of creatures
from the shapes of clouds.
It draws from a vast collection of data related
to the sky and clouds
to update you on a variety of weather conditions.

We’re using technology to reclaim
what technology took - our fascination with nature.
The movement to build a brighter tomorrow begins
by looking up.


  1. Scan
    Hold your smartphone up to the sky and use the camera to scan a cloud you want to know more about.
  2. Generate
    The app will convert the clouds into a creature, generating various animals and fun for both children and adults.
  3. Learn
    Meteorological information, weather forecasts and various facts about clouds and the sky will pique your interest in nature and the environment.


  • Cirrus

  • Cirrocumulus (mackerel sky)

  • Cirrostratus

  • Cumulonimbus (thunderclouds)

  • Altostratus

  • Altocumulus (sheep-back clouds)

  • Stratocumulus

  • Cumulus (cotton-like clouds)

  • Nimbostratus (rain clouds and snow clouds)

  • Stratus (fog-like clouds)

  • Cirrus
    Cirrus clouds are made up of clusters of wispy, white streaks. They appear frequently in spring and fall and look like they have been made by sweeping the sky with a broom.

    They are not a sign of immediate rainfall. The streaks generally stretch in the direction of an approaching low pressure area or a cyclone. This is usually taken as a sign that the weather will deteriorate the following day or within the next few days.

  • Cirrocumulus
    (mackerel sky)
    Cirrocumulus clouds consist of clumps of small clouds that resemble fish scales. They are widely known to indicate a change in weather conditions.

    The weather will deteriorate if they turn into cirrostratus clouds. There’s a chance that the weather will deteriorate the following day or within the next few days.

  • Cirrostratus
    Cirrostratus clouds are thin enough to let the sunlight through and can be identified by their veil-like appearance. They form beautiful rings of light, or “halos”, around the sun and the moon.

    The weather will go downhill as these clouds are considered precursors to bad weather.

  • Cumulonimbus
    Cumulonimbi are giant clouds that develop from cumulus clouds and occur frequently in the summer. They can reach heights of over 10km and thunder can occur within the cloud.

    Be wary of these clouds as they can produce torrential rain or hail.

  • Altostratus
    Altostratus clouds often form thick gray layers like a veil that cover the sky and block out the sun. While cirrostratus clouds form veils that cast shadows, altostratus clouds do not.

    These clouds are an indication that the weather will soon start to deteriorate. They produce light rain and drizzle, and can easily turn into nimbostrati.

  • Altocumulus
    (sheep-back clouds)
    Altocumulus clouds can be distinguished by rows and rows of round clouds that resemble sheep. The sheep-like clouds are gray at the bottom, and the individual lumps are bigger than those of cirrocumulus clouds.

    If blue skies can be seen from breaks in the clouds, it’s safe to assume that there’s only a low chance of rain.

  • Stratocumulus
    Stratocumulus clouds are large clouds rounded at the bottom that hang low in the sky.

    They generally do not produce rain, but when they do, it is only brief. These clouds are a sign of strong winds if their shape keeps changing.

  • Cumulus
    (cotton-like clouds)
    Cumulus clouds are fluffy clouds that float in the sky in clusters on a clear day. They can be seen all year round and form more easily over areas of land.

    Sunny weather will continue if the clouds stay the same shape, but they can also turn into cumulonimbus clouds.

  • Nimbostratus
    (rain clouds and snow clouds)
    Nimbostrati occur when altostratus clouds develop and thicken into dark, gray clouds that form thick layers which cover the sky.

    They are one of the most common types of clouds that produce rain and snow. Rain will soon start to fall if stray, scattered clouds appear underneath the cloud.

  • Stratus
    (fog-like clouds)
    Stratus clouds are white or gray clouds that look like fog. They are the lowest lying out of the all the clouds and can often be spotted in mountainous areas on cold mornings.

    These clouds can cause drizzle.
