This was a multipart, lab which included an overview, analysis, and evaluation of data using triangulated irregular network (TIN) and digital elevation model (DEM). As one would expect the lab with adding and symbolizing data using local scene in ArcGIS Pro.
Empowered some basic ArcGIS Pro Local Scene buttonology, the lab walk through preforming a ski run suitability analysis derived from a DEM which is converted to a TIN. This analysis not only provide the skills needed to analyze 3-dimensional data in a local scene but reinforced past skills learn in previous classes by reclassifying and performing a weighted overlay analysis to obtain the final suitability raster.

The final exercise in the lab leveraged the Contour tool to create isolines from a DEM and compare the results to the isolines symbolized from a TIN of the same area. As you may see from the image below the isolines created from the DEM are dependent upon the resolution (cell size) which in this case produced lines where appear smoother then the more jagged TIN isoline symbols.
