Map algebra expression used in the Mal-area calculator (MAC) within the web application MosquitoMap. Input values for different vectors (V1, V2 etc), disease (D) and Human (H) is 0 or 1, and weightings for vectors (WV1 to WVn) or disease (WD) are integer values of 1 to 10. Note if humans, vector or disease is absent for a pixel the result for that pixel is zero (example 1). Example 2 shows how the pixel value increases if one of the vectors is given a higher weight due to its vectorial importance. Input values for vector, disease and Human is 0 or 1, and weights are integer values of 1 to 10.
