In general, the rationale behind standardizing/normalizing the proximities for each factor is to ensure that the comparison are done on the same scale (i.e comparing apple to apple). The darker regions (black) represents, "better" - closer to the value of 1, and the lighter regions (towards red) represents "worse" - closer to the value of 0.

Criterion Score of Roads

Shown in the top left picture. As it is important that the quarantine centre is located nearer to roads, I inverted normalized roads, "1-Normalized_Roads", so that the darker regions (black) will show a more suitable representation of where to place the quarantine center.

Criterion Score of Buildings

There is no need to invert for Normalized_Buildings as land that is away from buildings are ideal. The red part represents the unsuitable area and the black part represents the more suitable area for the quarantine centre.

Criterion Score of Natural Conversation

There is no need to invert for Normalized_NaturalConversation as land that is away from natural features, namely - forested land, parks and water, are ideal. The red part represents the unsuitable area and the black part represents the more suitable area for the quarantine centre.

Criterion Score of Slope

As it is important that the quarantine centre is located on less steep slopes, I inverted normalized slope "1-Normalized_slope", so that the darker regions (black) will show a more suitable representation, less steep, of where to place the quarantine center.
