🌍 Geoscope

Instrument used in topography to sight an object and measure angles, especially azimuthal ones. Geoscope simulates its function with the line of sight.

Secondary line of sight in Geoscope, pointing opposite to the main one, useful for reading maps in reverse direction.

Point diametrically opposite another point on the Earth’s surface. Geoscope can locate it.

Apple’s development framework providing map data and tools for iOS applications. It is Geoscope’s default map provider.

Major crustal faults in metropolitan France, terrestrial extensions of the transform faults of the Mid-Atlantic Ridge.

Horizontal angle measured between geographic north and a given direction, clockwise (0–360°), or 0–180° with an explicit direction in structural geology.

Temporary memory used by Geoscope to locally store downloaded map data, allowing offline use.

A chain of volcanoes in France’s Massif Central, used in Geoscope as a practical example for recognizing volcanic landscapes.

Adjustable zone around the observation point where Geoscope performs place searches and sets line-of-sight lengths.

3D digital representation of terrain relief, without vegetation or buildings.

3D digital representation of Earth’s surface as observed, including vegetation and buildings.

Geoscope feature that adjusts the magnetometer to compensate for local electromagnetic disturbances that affect orientation.

Interference (from urban infrastructure, metallic objects, etc.) that can affect magnetometer accuracy. Geoscope allows correction.

Global leader in Geographic Information Systems (GIS), provider of several worldwide basemaps for Geoscope.

Imaginary line on a measuring instrument (compass, alidade) indicating the sighting direction. In Geoscope, it’s the main axis of device orientation.

Shortest path between two points on the surface of a sphere or ellipsoid (Earth), accounting for curvature. Geoscope uses these for long-distance calculations.

Zone of rupture in the Earth’s crust where rock blocks have moved. Geoscope helps identify and analyze their orientation.

Photograph automatically tagged with geographic position and orientation data (azimuths, cardinal points), making it a scientific document.

Satellite-based positioning system used by Geoscope to determine the user’s location.

Area within the Earth where magma rises, forming volcanoes (e.g., Iceland, Réunion). Geoscope can show directions toward them.

French organization providing detailed topographic maps (Scan 25, Ortho, DEM, etc.), available via Geoscope’s Premium Maps subscription.

Core Geoscope feature displaying in real time on the map and in the field the direction the device is pointing, enabling distant object identification and azimuth measurement.

Remote sensing technology (Light Detection and Ranging) using lasers to precisely measure distances and create 3D models of the ground surface, useful for Lidar DEM/DSM maps.

Geoscope’s ability to work with other navigation apps (Apple Maps, Google Maps) for direct guidance to selected places.

Apple’s mobile operating system, on which Geoscope runs (iPhone and iPad).

Premium Geoscope feature that fixes the line of sight in place for static map consultation.

Angular deviation between magnetic north (shown by a compass) and geographic north (shown on a map). Geoscope automates this correction.

Sensor in mobile devices measuring the magnetic field, used by Geoscope as a digital compass for orientation.

Pre-rendered image tiles composing a digital map, dynamically loaded depending on zoom and movement.

Provider of alternative map basemaps based on OpenStreetMap, with various graphic styles.

Submarine mountain range where new oceanic crust forms. Geoscope allows visualization of associated geodynamic directions.

Free, collaborative geographic data source, used by Geoscope for various map styles and search databases.

National mapping agency of the United Kingdom, with historical maps available in Geoscope.

Aerial photograph corrected for geometric distortions, providing an accurate, georeferenced view of the ground.

Direction toward the Kaaba in Mecca, essential for Muslim prayers. Geoscope can determine it accurately, accounting for Earth’s curvature and magnetic disturbances.

Branch of geology studying the organization, orientation, and evolution of deformations in the Earth’s crust. Geoscope provides a specific azimuth mode for this discipline.

Swiss Federal Office of Topography, renowned for the precision and quality of its maps (topographic, geological, historical), many of which are free in Geoscope.

Provider of thematic maps based on OpenStreetMap, with good relief rendering for geomorphological analysis.

U.S. government science agency, provider of topographic maps and imagery for North America in Geoscope.
