Grid Elevation Sampling Tool

Grid Elevation Sampling Tool: Free Terrain Analysis & Elevation Data Extraction

Grid Elevation Sampling Tool

Elevation Data Units:

Extract terrain elevation data for multiple points with our free elevation sampling tool. Generate customizable grid spacing for any location worldwide and download elevation data in CSV format. Perfect for GIS professionals, construction planners, environmental researchers, and land developers.

What You Can Do With This Tool

  • Create elevation grids with customizable spacing (10-1000 meters/30-3300 feet)
  • Extract elevation data for up to 20,000 points
  • Download terrain data in CSV format for GIS applications
  • Choose between meters and feet for elevation measurements
  • View your area in satellite, topographic, or street map views
  • Generate elevation points for construction sites, agricultural fields, or environmental surveys

How to Use the Elevation Grid Generator

Select Your Area

  • Navigate to your location using our interactive map
  • Choose your preferred map view (satellite, topographic, or street)
  • Draw a rectangle over your area of interest using the drawing tool

Configure Your Grid

  • Set your desired grid spacing in meters or feet
  • Monitor the point count estimate (maximum 20,000 points)
  • Generate your elevation sampling grid with one click

Get Your Elevation Data

  • Fetch elevation data for all points in your grid
  • Track progress for large datasets
  • Download your terrain elevation data as a CSV file
