Spatial Analysis of Accessibility of Wells using Map Algebra

4. Condition 2: No Industry, Mine, or Landfill within 300 Meters from Wells

For the second condition we first need to reclassify the buildg layer in such a way that the result is a Boolean map with True (1) for industry, mine, and landfill and False (0) for the other classes. Then we need to calculate the distance to the True pixels and finally calculate the pixels that are further than 300 m from industry, mine, and landfill.
