Two Buttes
Natural Neighbor, r-variable
Kriging, g-variable
II. Interpolating Airborne Lidar Data
Trend, x-variable
IDW, z-variable
Question1: Now that you have interpolated terrestrial and airborne lidar data using GIS, how do different interpolation measures differ visually? What differences, if any, do you detect?
Some interpolation came out very linear in columns or rows. Other interpolation appears to follow contours or groups. It depends on the variable (i.e elevation, longitude, latitude) and what you are interpolating. There probably is no trend to contour data whereas kriging and natural neighbor would visualize better, thus the trend data showed very little.
III. Analyzing DEM's
Hillshade View of the Mount Lincoln, Bross, and Cameron Region
(500 foot contour lines labeled)
Question Two: What is the vertical elevation loss between Mt. Cameron and Mt. Lincoln?
Inserting contours down to 25', the saddle between Lincoln and Cameron is approximately 14,100 feet. Thus, there is an approximately 138 foot vertical elevation loss from Cameron to the saddle.
Question Three: According to 14er "rules," is Mt. Cameron an "official" 14er?
No! There must be at least a descent of 300 feet to the saddle. Thus, it is unranked.
