Document Summary

Gis in water resources midterm exam fall 2016. Question 1. (20%) (a) three key functions of gis are visualization, data storage, and analysis. For arcgis pro, briefly describe the components that achieve these functions: Analysis (b) two key datasets that we have used in this class are nhdplus and the national elevation. Briefly outline what each of these datasets describes and what data type (vector or raster) is used to represent it. National elevation dataset (c) we can show location on earth using geographic and projected coordinate systems. Briefly describe these coordinate systems and specify the map units that would be used in each case. The map below shows the continental united states in geographic coordinates overlaid by a grid which has 10 x 10 cells. The parameters are given below of a map projection you have used in this class. Draw on the map above the central meridian, reference latitude, and standard parallels used in this projection.
