In this article you will learn how to create test areas for landscape classification.
- Generating sample points
- Load the raster map 188_pca_indices, which should be available in the course data.
- Open Vector --> Research tools --> regular points. If not selected by default, set the Input Boundary Layer to 188_pca_indices.
- Select the radio button Use this number of points and set the number to 50.
- Set Initial set from corner (LH side)
