What are the characteristics of the sampling network and the distance between the network points and the number of samples for preparing training samples (areas) and the points needed for the accuracy assessment in the classification of remote sensing images in evaluating a study area for the following three cases?
1- land use mapping
2- forest and non-forest mapping
3- forest canopy density
Dear Naser ahmadi sani , it is associated with the experimental design itself. That is to say, before talking about sensor networks, you should analyze the measurement process and the experimental design underlying. It is essential to ensure the repeatability, consistency, and extensibility of the measurement process. Also, a good measurement process should ensure comparable measures for performing different evolution analyses.
I suppose that in this case, you could carry forward a stratified sampling, considering each kind of particularity into the heterogeneity of the sensed region. From the statistics, there are different formulas to estimate the sample size for each region.
I mean, in each case, the measurement techniques, sensors, and requirements could vary sensibly according to the experimental design. I suggest taking a look to the measurement frameworks, ISO 25012 (Data Quality), and how to automatize the experimental design through the measurement process.
For your reference, here you have a review about how the particulate matter is measured today through IoT sensors:

I hope that it is useful for you!
