 Dot Sampling Method
Welcome to the Dot Sampling Research Center. This is a web site which is established to share knowlege and techniques on the Dot Sampling Method. If you use the method, you can directly take a sample for a crop production survey on Google Earth Pro. Therefore it does not require to construct traditional sampling frames such as list frames or physical area frames for area surveys, yield surveys. Furthermore, the area survey based on the method is very simple, because it can be conducted with the attribute judgement method at each sample point without measuring.
We appreciate many people have participated and cooperated in the development and improvement of the method. It would be great pleasure if this small site was helpful.
