The document analyzes different geodata resolutions (1m, 5m, 10m) for coverage prediction accuracy in urban, suburban, and rural morphologies. For urban and suburban areas, 5m resolution is recommended as the delta between 1m and 5m predictions is marginal. For rural areas, 10m resolution can be considered as the deltas between 1m and 10m are smaller than in urban/suburban areas. The key factors analyzed are coverage prediction, histograms, statistics, and percentage deltas between resolutions.

Clutter Classes vs Morphology Definition Methodology
 Steps Followed for Geodata validation & Recommendation:
i. Identified different morphology on basis of above-mentioned clutter vs morphology definition.
ii. Identify a nominal site location in different morphology.
iii. Create a polygon/ filtering zone surrounding to nominal sites.
iv. Define set of parameters & propagation model according to 1m/5m/10m geodata resolution.
v. Run Prediction of the site
vi. Generate Histogram & stats of the prediction
vii. Repeat step 1 to 6 for different geodata resolution (1m/5m/10m)
viii. Compare analysis & stats of 5m & 10 m resolutions with 1m resolution as reference
• Antenna Height: 6m
• Azimuth: 0/120/240
• Antenna: 90 Deg. HBW with 14.5dBi gain
• Propagation model: Default Aster
