Map Calculator

Marea is a versatile map calculator that lets you measure area, distance and perimeter on any map worldwide. Whether you’re working with satellite imagery or a standard road map, Marea gives you accurate measurements with just a few taps.

What Can You Calculate on a Map?

Area

Select any region on the map and calculate its area. Results are shown in square meters, square feet, acres, hectares, and more — all at the same time.

Distance

Measure the straight-line distance between two points, or trace a path along roads and boundaries to get the total distance.

Perimeter

Trace a closed shape and get both the area and the full perimeter measurement in one step.

Price Estimation

Assign a monetary value per unit area to quickly estimate land value, material costs, or project pricing.

Map Views Available

Satellite View

High-resolution aerial imagery lets you see actual terrain, buildings, vegetation and physical boundaries. Best for:

• Identifying property lines from fences, walls and hedges
• Measuring rooftops and building footprints
• Assessing agricultural land and field boundaries
• Exploring remote or undeveloped areas

Standard Map View

Road map view shows streets, labels, and administrative boundaries. Best for:

• Measuring along roads and paths
• Identifying named locations and addresses
• Working in urban areas with complex street layouts
• General navigation and orientation

Use Cases

Real Estate

Calculate lot sizes, measure frontage, compare properties, and assess land value. Use satellite view to verify listed property dimensions.

Agriculture

Measure field areas for crop planning, calculate acreage for reporting, and map farm boundaries. Switch between fields and track total managed acreage.

Construction

Measure building sites, calculate excavation areas, plan material quantities, and assess project scope from anywhere.

Outdoor Planning

Measure park boundaries, recreational land and managed outdoor areas. Useful for rangers, managers and land planners.

Education & Research

Measure geographic features, compare region sizes, and calculate distances for academic projects and research.

How It Works

1. Open Marea and navigate to any location on the globe
2. Choose your view — satellite or standard map
3. Tap to place pins around the area or along the distance you want to measure
4. Read results — area, distance, and perimeter are calculated in real time
5. Save or share — store your measurement or export as KML

Global Coverage

Marea works with any location that has map coverage — from urban city centres to remote farmland. Satellite imagery resolution varies by location, but is typically detailed enough for accurate boundary identification in most populated areas.
