If you have a raster data layer that is set up on a grid of 30m x 30m, what is its resolution?Group of answer choices30m10 feet3m10m

Break Down the Problem

1. Identify what raster data resolution means.
2. Determine the dimensions of the grid cells.

Relevant Concepts

• The resolution of a raster data layer is defined by the size of each cell in the grid.
• In this case, we have a grid of 30m x 30m.

Analysis and Detail

1. The cell size of 30m means that each cell in the raster covers an area of 30 meters by 30 meters.
2. To understand the significance of the size in other units, we note:
   • 30 meters is approximately equal to 98.43 feet.
   • Since 1 meter is approximately 3.281 feet, $30 \, \text{m} \times 3.281 \, \text{ft/m} \approx 98.43 \, \text{ft}$.

Verify and Summarize

• The resolution is directly stated from the grid size, which confirms that the raster resolution is 30m.
• While 30m can be converted to feet, it is unnecessary for determining the resolution value.

Final Answer

The resolution of the raster data layer is 30m.
