Seasonal Forest Basal Area Estimates from Smartphone and Professional LiDAR in Romania

Jenny Magaly Morocho Toaza published data evaluating seasonal performance of basal area estimation using a smartphone LiDAR app and a professional scanner. The study collected data from 50 circular plots in heterogeneous mountain forests near Brașov, Romania, across four phenological stages: winter, spring, summer, and autumn. Results include bias, mean absolute error, root mean square error, and acquisition time comparisons between the two systems.

Use Cases

• Compare smartphone-based and professional LiDAR system accuracy for forest inventory based on seasonal performance metrics.
• Analyze the impact of phenological stages on remote sensing measurement agreement based on data collected in winter, spring, summer, and autumn.
• Evaluate operational efficiency of forest data acquisition based on the comparison of acquisition times between systems.
• Model stand-level basal area in complex terrain based on data from plots on slopes of 8°–42° in mixed species stands.

Strengths

• Data collected from 50 circular plots (300 m² each) providing a basis for statistical analysis.
• Longitudinal repeated-measures design across four distinct phenological stages (WI, SP, SU, AU).
• Includes specific error metrics (e.g., RMSE = 0.093 m² in winter) and statistical test results (p-values).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is limited to a specific geographic region (mountain forests near Brașov, Romania).
