| − | The selected site should avoid steep slope. This is because construction at steep slope tends to involve a lot of cut-and-fill and will lend to relatively higher development cost.
| + | </table> |
| − | According to Legal Eagle Contractors, Co. [1], "Less than 10% incline is considered slight and is the easiest to build on, while 11-20% is considered moderate. Anything above 20% is deemed steep.". Hence, I used that as the measure to deem if an area is too steep for building the site.

| − | === Accessibility Factor === | + | === Maps === |
| − | The selected site should be close to existing local roads, namely: service roads and tracks. This is to ensure easy transportation of building materials during the construction stage.
| |
| − | I assume that for the site to be accessible, the site must be at least 200m away from local roads.
| |
| − | I used a binary model, where I gave a score of 1 for the areas that were within 200m from a local road, and a score of 0 for the areas that were more than 200m away from a local road.

| − | === Health Risk Factor ===
| + | [[File:4maps1.png|1000px|thumb|center]] |
| − | The selected site should be away from population i.e. housing areas and offices in order to avoid disease spreading to the nearby population.
| |
| − | I assume that for the site to be sufficiently far away from buildings, it needs to be minimally 250m away from buildings.
| |
| − | I used a binary model, where I gave a score of 1 for the areas that were at least 250m away from buildings, and a score of 0 for the areas that within 250m away from a building.
| |
| − | | |
| − | === Natural Conservation Factor ===
| |
| − | The selected site should be away from forested land, park and water.
| |
| − | I assume that for the site to be sufficiently far away from natural conservation sites, the site must be at least 200m away from natural sites.
| |
| − | I used a binary model, where I gave a score of 1 for the areas that were at least 200m away from natural sites, and a score of 0 for the areas that within 200m away from a natural site.

| − | === Final Output ===

| − | | |
| − | I used the Raster Calculator to calculate the final scores to deduce where would be the best area to build the site, with the formula "Accessibility@1" + "Economic_Rank@1" + "HealthRisk@1" + "Natural_Binary@1".
