The Geometric Measurement Tool is a powerful web application designed to measure complex geometries in images. It's perfect for analyzing:
Measure distances and areas in regular photographs
Analyze distances and areas from drone or satellite photos
Take measurements directly from map images
Click the "Upload Image" button and select a photo, aerial image, or map. The image will be displayed on the canvas, ready for measurements.
Select the "Line" tool and draw a line on an object with a known measurement. The line will be automatically selected when you finish drawing.
Tip: Hold Shift while drawing to snap lines to 0°, 90°, 180°, or 270°.
With the line selected (automatically after drawing), enter its real-world measurement, choose the unit (mm, cm, m, or km), and click "Set Reference".
Alternative: Use "Apply Scale" if you know the scale ratio (e.g., 1:400).
Now you can draw lines and polygons to measure distances and areas. All measurements will be calculated automatically based on your reference.
Measure distances and areas from architectural plans, construction site photos, or building blueprints.
Calculate land areas, plot boundaries, and distances from aerial imagery or survey maps.
Measure distances between locations, calculate areas of regions, or analyze spatial relationships on maps.
