Terrain Elevation Profile vs Field Area Measure

Viewshed & Line of Sight is a terrain visibility analysis app that shows what can and cannot be seen from any location on Earth using elevation data. Plan, explore and analyze terrain with clear visual tools for visibility and line of sight. KEY FEATURES Viewshed analysis * Generate visibility maps from any location * Free up to 5 km radius * Premium up to 30 km radius Line of sight analysis * Check visibility between any two points up to 500 km * Identify whether terrain blocks or allows visibility Terrain profiles (premium) * View elevation changes between points * See peaks along a path * Export terrain profile to CSV Search and navigation * Search locations and coordinates * Explore locations worldwide instantly Export and data tools (premium) * Export viewshed maps * Export terrain profiles * Export CSV data for further analysis PREMIUM FEATURES * Higher resolution 30 m terrain data (limited to North America, EU without Greece and Finland, Japan and New Zealand) * Improved accuracy for visibility analysis * Extended viewshed range up to 30 km * Advanced terrain profile tools and exports USES CASES * Hiking and outdoor exploration * Radio and antenna planning * Telecom and network analysis * GIS and mapping projects * Photography and viewpoint scouting NOTE Results are based on digital elevation models and may not include buildings, vegetation or temporary obstacles.

Measure any piece of land straight from the map - no equipment, no walking the boundary. Tap the corners or trace the edge with your finger, and the area updates as you go. THREE MODES - Area - a field, plot, roof or lawn - Distance - a fence line, a path, a run of pipe - Point - a single marked location DRAW IT YOUR WAY Tap corner by corner, trace freehand, or line up the crosshair and add points one at a time. Drag any corner to correct it. Undo anything. YOUR UNITS Acres, hectares, square meters, square feet, square yards, square kilometers, square miles. Meters, kilometers, feet, yards, miles, nautical miles. Every result carries a second unit underneath, so a figure reads both ways without switching. STANDARD, SATELLITE OR HYBRID Satellite and hybrid imagery show crop boundaries and field edges that the standard map does not. KEEP AND SHARE Saved measurements live in a searchable library, each with a thumbnail of its shape. Export to KML, GPX, GeoJSON, CSV or an image. Open KML and GPX files sent from Files, Mail or any other app. ALSO INCLUDED A full-screen compass showing your heading and coordinates, ready to copy. MEASURED PROPERLY Distances use Vincenty's inverse solution on the WGS-84 ellipsoid; areas use spherical excess. No accounts, no subscriptions, no ads, no third-party code. Your measurements stay on your device.
