Physical measurements, like reflectance from Landsat or water turbidity, are typically continuous. Discrete raster data are things like counts and representation of categorical values (like classification). The only type of direct, discrete measurement I can think of is if you're only measuring occurence of something (which is basically binary classification if you count occurences it's no longer just classification).

Chapter 7 Raster Geospatial Data - Discrete | Geographic Data Science with R: Visualizing and Analyzing Environmental Change
The previous chapter covered raster datasets with continuous variables, which potentially have an infinite number of values. This chapter introduces raster datasets with discrete variables, which are classified into a limited number of values. We still use numbers to work with discrete data.

After downloading and uncompressing the GeoTiff data, warp each image to the proper projection as we did to the Natural Earth GeoTiff. Warp all the images and move the reprojected ones to a directory called target (using Terminal): ls *.tif > abc mkdir target while read line do file=$(echo $line |awk -F. '{ print $1 }') gdalwarp -t_srs EPSG:3857 $line target/$file.tif done < abc · Since TileMill natively supports GDAL’s Virtual Raster (VRT) format, we can take advantage of a VRT rather than creating a new GeoTIFF mosaic.

March 10, 2024 - In a discrete raster land cover/use map, you can distinguish each thematic class. Each class can be discretely defined where it begins and ends. In other words, each land cover cell is definable and it fills the entire area of the cell. Discrete data usually consists of integers to represent ...

r/gis on Reddit: Is my data discrete or continuous?
October 25, 2023 -
Hi! I am doing a project for a GIS class and one of the requirements is to include modeling or analysis using a continuous field. My project proposal was using LandSAT bands to determine turbidity in a water body. I am following the methodology of a paper that uses an equation to convert two LandSat bands into turbidity values (FNU). Are these values continuous or discrete? I got brief feedback from my professor that I need to include some sort of continuous data and I am unsure how the turbidity values are not considered continuous? Any ideas how I can include some continuous data into my project if turbidity is discrete? Thanks for the help, I am not the best at GIS and this class is way harder than I expected.

June 1, 2025 - While the nearest neighbor resampling takes the cell center from the input raster data, the majority algorithm uses the most common values within the filter window. Similar to the nearest neighbor algorithm, this technique is commonly used for discrete data like land cover classification and other types of raster grids with distinct boundaries.
