Digital elevation models are digital representations of the Earth's surface. Digital elevation models can be represented through raster models or TIN (triangulated irregular network). The maps we created in this lab included shaded-relief, aspect, slope and 3-Dimensional maps. DEM's are widely used for multiple map applications. Creating a DEM was extremely easy and I think that is an important aspect to DEM. The fact that digital elevation models are relatively easy to create is helpful when creating physical models of the Earth's terrain. Moreover, DEM's can exhibit morphology of land elevation and this is significant in terrain analysis. However, a DEM map is not 100% accurate as a cell value can hold only so much detail. Overall, this lab was an enjoyable experience.
