Cheaper, Faster, and More Than Good Enough : Is GPS the New Gold Standard in Land Area Measurement?

In rural societies of low- and middle-income countries, land is a major measure of wealth, a critical input in agricultural production, and a key variable for assessing agricultural performance and productivity. In the absence of cadastral informat...
