Data Collection

Data Collection Process

The data collection process involves gathering geospatial data using various methods, including:

  • GPS (Global Positioning System): Used to collect precise location data for trees and other features in the study area.
  • Field Surveys: Conducted to measure tree parameters such as diameter at breast height (DBH), tree height, and wood density.
  • Remote Sensing: Satellite imagery and aerial photography are used to collect large-scale data on forest cover and land use.

Key Steps in Data Collection

  1. Site Selection: Identify the study area and select sampling plots for data collection.
  2. Field Measurements: Measure DBH, tree height, and collect wood samples for density analysis.
  3. Data Recording: Record all measurements and observations in a structured format for further analysis.
  4. Quality Assurance: Validate the collected data to ensure accuracy and consistency.

Tools and Equipment

The following tools and equipment are used during the data collection process:

  • GPS devices for location tracking
  • Diameter tapes for measuring DBH
  • Clinometers for measuring tree height
  • Wood density measurement tools
  • Field notebooks and digital data loggers
Quick Summary

Data collection is a critical step in the GIS analysis process. It involves gathering accurate and reliable data using GPS, field surveys, and remote sensing techniques.
