Crop Identification

Objective

Identify the crops in each field, based on satellite images collected at different times of the year.

Materials

•	Satellite images of the same location, taken at different dates (overleaf)

Procedure

Satellite images of an agricultural area in central Greece, were acquired on April and November (see the other side of this sheet). The images show the same fields at those two dates.
	
The main crops in this area are corn, cotton and winter wheat. Identify which crop is cultivated in each of the circled fields on the images bearing in mind that:

Corn is planted sometime between April and June and harvested between August and October. Also, corn takes a while to grow to a decent size (hence not seen clearly from a satellite at the early stages).

Cotton is planted in February/March and harvested in July/August.

Winter wheat is planted in September and harvested in June/July.
