In the raster calculator, what is the result of the expression Con("Area Solar Rad" > (75000 + 3*4900.093), 1)?

The expression in the raster calculator utilizes the Con function, which stands for "Conditional." This function evaluates a condition and returns specified values based on whether the condition is true or false. In this case, the condition being evaluated is whether the values in the "Area Solar Rad" dataset are greater than the result of the expression (75000 + 3*4900.093).

When the condition is true—that is, if the values in "Area Solar Rad" exceed the calculated threshold—the Con function returns 1. This means that for all pixels (or grid cells) where the solar radiation values surpass this threshold, the result will be 1, indicating that they meet the specified solar radiation condition.

If the condition is false (the solar radiation values do not exceed the threshold), the Con function would not return a specified value for those cells, leading to a default output, but that is outside the context of the chosen answer.

The choice correctly identifies that the result of the expression outputs 1 for values exceeding the condition, spotlighting how conditional logic in raster calculations operates in GIS applications. This understanding is essential for interpreting results from raster analyses, specifically in how specific criteria can be applied to spatial datasets.
