I use both vector and raster spatial for my field data. I have my GPS on tracking mode to take a point of my swim pattern every 10 second. My GPS tracks are vector data. While I am swimming in the reef flats I conduct surveys to determine the type of macroalgae present every 30 second of my swim, the density of the macroalgae and the percent cover for hard live coral. The data collected from these surveys I would say are raster data.
