Remote sensing and Landsat data imagery provide many provide substantial benefits when analyzing a space.
Landsat imagery allows you to differentiate the space between it’s different land uses and land covers. remote sensing does this by recording the wavelength of light reflected off the surface back to the camera and creates raster data based off the dominant material in the grid cell.
This can be especially useful in scenarios where you’re trying to isolate surfaces within a large range. For example if you were looking for invasive species cover within Vancouver parks you would just need to determine the wavelength signature of the species then use Landsat imagery data to determine all cells reflecting the wavelength signature specific to that species.
