Elevation Interpolation

Creation Process:

• The map was created using Inverse Distance Weighting (IDW), a geostatistical interpolation method in ArcGIS Pro. IDW assumes that locations closer together have similar values and uses known data points to estimate values at unknown locations.

• Two surfaces were generated: a smooth IDW surface with default parameters and a more optimized version with adjusted power values, emphasizing the influence of closer data points.

• The IDW method was chosen for its simplicity and exact nature, creating a predicted surface that directly reflects the sampled elevation data.

Visual Details:

• The map displays filled contours representing different elevation ranges across Dog Island, highlighting areas of higher and lower elevations.

• Points on the map represent discrete elevation measurements, which were used to create the interpolated surfaces.

• An inset map provides geographical context, showing the location of Dog Island relative to the United States.
