P502 satellite image and schematic

We tried to find a vacant space by human visual system in parking lot 502.

Even though this satellite image is the best quality we can get now, some of the spaces are very difficult to distinguish because of the shadows in some spaces.

To handles these uncertainties created by shadows,

we labled each space with 5 different categories.

1 - occupied

0 - vacant

v - most likely vacant (the spaces that are partially covered by the shadow)

m - most likely occupied(the spaces are covered by the shadow, but the car is still visible)

n - not sure(the spaces that are too dark to identify)

The purpose of this labeling is to handle uncertainties before sending information to the users.
