Question:

Select the method(s) that can be used for landuse classification based on satellite images.

Show Hint

For landuse classification, focus on algorithms used in remote sensing and image processing (e.g., Maximum Likelihood, K-Means, ANN). Avoid mixing them with unrelated optimization or OR techniques.

The Correct Option is A, C, D

Solution and Explanation

Step 1: Understand the problem.
Landuse classification using satellite imagery involves categorizing different land cover types (forest, water, urban, agriculture, etc.) based on spectral signatures. This is a problem of image classification, and several algorithms can be applied.

Step 2: Examine each option. \begin{itemize} \item Option (A): Maximum Likelihood
This is a supervised classification method widely used in remote sensing. It assumes the data follow a normal distribution and classifies pixels based on probability. Hence, this method is valid. \item Option (B): Northwest Corner Method
This method belongs to Operations Research (used for solving transportation problems). It is unrelated to satellite image classification. Therefore, this option is invalid. \item Option (C): K Means
K-Means clustering is an unsupervised classification method, commonly applied in remote sensing to partition pixels into clusters without prior training data. Hence, valid. \item Option (D): ANN (Artificial Neural Networks)
ANNs are advanced machine learning models that can classify satellite images with high accuracy, especially with large datasets. Hence, valid. \end{itemize}

Step 3: Final Selection.
Valid methods are: Maximum Likelihood, K Means, and ANN.

Final Answer: \[ \boxed{(A), (C), (D)} \]
