Lab 5

Part 1

This map shows the annual precipitation in Idaho, based on values from weather stations scattered throughout the state. The Inverse Distance Weighting Method was used to create the values that cover the state and the contour option in the spatial analyst toolbar was used to create the contour lines. For the interpolation, the optimal power value was calculated and 15 neighbors were used. Using this color scheme made the most sense to me for representing precipitation. To make the contour line numbers stand out a bit better, a small halo was added to them and they were then shifted to make them easier to read. To explain more about the contour lines, text was added to the map for clarification.

Part 2

This map shows the annual precipitation in Idaho, based on values from weather stations scattered throughout the state. The Ordinary Kriging Method was used to create the values that cover the state and the contour option in the spatial analyst toolbar was used to create the contour lines. For this interpolation, the best RMS value was found be of the Exponential model using 10 neighbors and a calculated lag with 12 lags. Using this color scheme made the most sense to me for representing precipitation. To make the contour line numbers stand out a bit better, a small halo was added to them and they were then shifted to make them easier to read. To explain more about the contour lines, text was added to the map for clarification.
