• Forestry Inventory Report Digimedfor Sample.pdf: A detailed forestry inventory report that includes the methodology, stand-level summaries, and spatial distribution maps (e.g., diameter at breast height, basal area, dominant height, and tree density).
• Individual_stem_inventory_Digimedfor_sample.xlsx: A dataset containing the individual stem inventory. It provides key dasometric variables for every identified tree, such as Diameter at Breast Height (DBH), total height (StemHeight_m), stem volume (StemVol_m3), and total volume.
• individual_stem_inventory_Digimedfor_sample_25830epsg.geojson: A vector geographic data file containing the exact location of each tree along with its associated attributes, projected in the ETRS89 / UTM zone 30N coordinate system (EPSG:25830). This file is ideal for accurate spatial analysis and metric measurements.
• individual_stem_inventory_Digimedfor_sample_4326epsg.geojson: A vector geographic file identical to the previous one, but transformed into the global WGS 84 coordinate system (EPSG:4326).
