## Files

*   **train.csv** - the training set
*   **test.csv** - the test set

## Columns

*   `id` - The `id` of this city, for example, `id` 1 corresponds to the image in `1.jpg`.
*   `sqft` - square feet of the city in millions of square feet.

## Other notes

* Remember your target is an area, not a volume.  The square feet, in millions, is equal to the sum of each building's `width * height * floors`.
* The height of each floor is regulated by the nation to an undisclosed (yet uniform) number of feet.
