Reports: Maps, Inventories, and Risk Assessments

Skip hours of manual report assembly. Lidarvisor generates professional, client-ready documents directly from your processed data — topographic maps in DXF, tree-by-tree forest inventories with carbon estimates, and vegetation risk reports for utility compliance.

Topographic Map (DXF)

What It Is

A layered CAD drawing that combines multiple elements of your survey into a single, print-ready topographic map. It is delivered as a DXF file — the standard exchange format for CAD applications like AutoCAD, Civil 3D, BricsCAD, and others.

What It Contains

The topographic map includes separate layers for each feature type:

• Major and minor contour lines (with elevation labels)
• Elevation grid points
• Building footprints
• Tree top positions (with height annotations)
• Tree crown outlines
• Power line cables
• Towers and poles
• Roads

Each element is placed on its own layer within the DXF file, so you can toggle them on or off in your CAD software — just like you toggle layers in Lidarvisor's viewer.

Layout Features

The DXF includes:

• A title block with project information, date, coordinate system, and scale
• Proper paper size formatting (ISO A0 or US ARCH D)
• Automatic scale selection (from 1:100 to 1:10,000 depending on the area size)

Who Uses This

• Surveyors delivering topographic survey results to clients
• Civil engineers using the map as a base for design work
• Architects incorporating terrain data into site plans
• Permit applicants submitting site documentation to authorities

How to Access

After processing, the topographic map appears in the Reports section of the project tree. Click the download button to get the DXF file (packaged as a ZIP with supporting data files).

Digital Forest Inventory

What It Is

A comprehensive tree-by-tree analysis of every tree detected in your survey area. It includes both a visual PDF report and a detailed CSV spreadsheet.

What the PDF Contains

1. Introduction page — project overview with summary statistics:

   • Total number of trees detected
   • Average and maximum tree height
   • Average crown area
   • Total canopy cover

2. Full-extent map — a bird's-eye view of the entire survey area showing:

   • The Canopy Height Model (vegetation height map) as background
   • All detected tree crowns as colored outlines
   • Tree top positions as dots
   • Tree ID labels
   • A 250-meter reference grid

3. Detail pages — zoomed-in views of each grid cell, showing individual trees clearly with their IDs and measurements

4. Carbon estimation summary (if enabled) — a section summarizing:

   • Total above-ground biomass (AGB) in tonnes
   • Total below-ground biomass (BGB) in tonnes
   • Total carbon stock in tonnes
   • Total CO2 equivalent in tonnes
   • Breakdown by species (if multiple species are present)

What the CSV Contains

A row for each detected tree with columns including:

• Tree ID
• X and Y coordinates (geographic position)
• Height above ground (meters)
• Crown area (square meters)
• Estimated trunk diameter (DBH — Diameter at Breast Height)
• Above-ground biomass (if carbon estimation enabled)
• Below-ground biomass (if carbon estimation enabled)
• Carbon stock (if carbon estimation enabled)
• CO2 equivalent (if carbon estimation enabled)

Carbon Estimation

When you enable the Carbon Estimation option, Lidarvisor calculates the carbon stored in each tree using scientifically validated formulas called allometric equations. These equations estimate the mass of a tree based on its measurable dimensions (height and crown size).

To get the most accurate results, you need to select:

• Allometric Region — the geographic region closest to your survey area:

  • Europe
  • Canada
  • USA
  • Tropical
  • Australia
  • Boreal / Russia
  • East Asia
  • African Dryland

• Dominant Tree Species — the most common tree species in the area. The list changes based on the selected region. Examples include:

  • Europe: Scots Pine, Norway Spruce, European Beech, Pedunculate Oak, Silver Birch, etc.
  • USA: Douglas Fir, Loblolly Pine, Red Maple, White Oak, etc.
  • Tropical: Generic tropical hardwood, Teak, Mahogany, Eucalyptus, etc.

The carbon estimation follows methodologies referenced by the IPCC (Intergovernmental Panel on Climate Change) and uses region-specific root-to-shoot ratios to estimate below-ground biomass.

Who Uses This

• Forestry professionals managing timber resources
• Environmental consultants assessing ecological value
• Carbon credit projects quantifying sequestered carbon for trading or offsetting
• Government agencies monitoring forest health and growth
• Research institutions studying forest dynamics

How to Access

After processing, the forest inventory appears in the Reports section of the project tree. Click the download button to get a ZIP file containing the PDF report and CSV spreadsheet.

Vegetation Encroachment Report

What It Is

A specialized report for utility companies and vegetation management teams that identifies trees and vegetation posing a risk to power line infrastructure.

What It Contains

The report includes:

1. Buffer zone analysis — maps and lists of vegetation found within each defined buffer zone around the power lines. Each zone corresponds to a different risk level.

2. Clearance violations — specific locations where vegetation is closer to a power line than the minimum safe distance you defined. Each violation includes:

   • GPS coordinates
   • Distance to the nearest wire
   • Type of vegetation
   • Height of the vegetation

3. Fall-risk trees — trees identified as tall enough to potentially reach a power line if they fell. Each at-risk tree includes:

   • GPS coordinates
   • Tree height
   • Distance to nearest wire
   • The wire span affected

4. Overview maps — bird's-eye view maps showing the power line corridor with color-coded risk areas.

Regulatory Context

Many countries and regions require utility companies to maintain minimum clearance distances between vegetation and power lines. In the United States, the NERC FAC-003 standard mandates regular vegetation management around transmission lines. This report provides the documentation needed for compliance.

Who Uses This

• Utility vegetation management teams planning trimming and removal programs
• Power companies documenting compliance with regulations
• Arborists and tree service contractors prioritizing work orders
• Insurance assessors evaluating risk exposure
• Government regulators reviewing compliance reports

How to Access

After processing (with power line extraction and buffer/clearance options enabled), the report appears in the Reports section of the project tree. Click the download button to get the PDF and supporting files.

Tips for Working with Reports

• PDF reports can be opened in any PDF viewer (Adobe Reader, web browser, Preview on Mac).
• CSV files can be opened in any spreadsheet application (Microsoft Excel, Google Sheets, LibreOffice Calc).
• DXF files can be opened in any CAD application. Free options include LibreCAD, FreeCAD, or the free viewer from Autodesk.
• All geographic data in the reports uses the same coordinate system as your original LiDAR file, so positions match your survey control.
