Pixel Value Mm2 -

Calculating this metric requires two pieces of information:

Without this conversion, data is unrepeatable.

At its core, the pixel value mm² refers to the physical area on an object or scene that is represented by a single pixel in a digital image. It is a measure of spatial resolution. pixel value mm2

Let’s break down the terminology:

Therefore, if a system has a pixel value of 0.5 mm², it means that each pixel in your image corresponds to a 0.5 mm x 0.5 mm square on the real object (assuming square pixels, which is standard). Calculating this metric requires two pieces of information:

Satellites like Landsat, Sentinel-2, or commercial providers (Maxar, Planet) provide imagery where each pixel corresponds to a massive ground area. For instance:

When a scientist calculates deforestation or the area of a wildfire scar, they count the number of “burned” pixels and multiply by the pixel value in mm² (or m²). A forest fire covering 500,000 pixels in a Landsat image means the actual burned area is 500,000 × 900 m² = 450 km². Therefore, if a system has a pixel value of 0

[ \textArea per pixel = (\textmm per pixel)^2 ] Example: 0.0847 mm/pixel → area = (0.0847^2 \approx 0.00718\ \textmm^2/\textpixel)
