This glossary explains the core vocabulary behind maps, GeoJSON, Workspace, manifests, styling, and the API. Start here when you want clearer language for how Atlasemoji works and how structured geography moves through the system.
A map is a visual representation of geographic space that helps people understand location, distance, and relationships between places. In Atlasemoji, maps are surfaces where structured geographic objects can be created, edited, viewed, and shared.
A coordinate is a numeric value that defines a specific position on Earth using latitude and longitude. Coordinates allow computers to place points, lines, and polygons accurately on a map.
Latitude measures how far north or south a location is from the equator. Latitude combines with longitude to form coordinates that identify precise locations.
Longitude measures how far east or west a location is from the Prime Meridian. Longitude combines with latitude to form coordinates used in mapping systems.
Geometry is the mathematical description of spatial form using points, lines, and shapes. In mapping systems, geometry defines where geographic features exist and how they relate to space.
A point is the simplest geometry type and represents one specific location using a single coordinate pair. Points are often used for places such as landmarks, observations, and waypoints.
A LineString is a sequence of coordinates connected in order to represent movement or connection between places. LineStrings are used for routes, paths, and linear features.
A polygon is a closed shape defined by a sequence of coordinates that begins and ends at the same position. Polygons represent areas such as boundaries, zones, or regions of interest.
GeoJSON is a structured format for representing geographic data using JSON syntax. Atlasemoji supports GeoJSON because it keeps geometry and descriptive properties connected in one reusable object.
A Feature is a GeoJSON object that combines geometry with descriptive information stored in properties. Features allow geographic shapes to carry meaning such as names, notes, identifiers, and styling.
A FeatureCollection is a GeoJSON object that groups multiple Features into one dataset. FeatureCollections allow related geometry objects to be managed, imported, edited, and shared together.
A Workspace is the Atlasemoji editing surface where geographic data is created, refined, organized, and prepared for reuse. Workspace lets users shape geometry, adjust layers, inspect structure, and move data toward publishable outputs.
A waypoint is a stored geographic location used as a reference point within Atlasemoji datasets. Waypoints often connect geographic structure with descriptive or narrative meaning.
A manifest is a structured record describing how geographic data is organized and related. Manifests allow datasets to be reused consistently across maps, stories, embeds, and APIs.
A layer groups related geographic objects so they can be understood together. Layers help separate different types of meaning within the same dataset and keep maps readable as complexity grows.
routeId is an identifier used to connect related waypoints or geometry into a logical sequence. routeId helps organize spatial objects that belong to the same route or dataset.
Style defines how geometry appears visually on the map. Style properties control color, opacity, width, and other display characteristics that help users interpret meaning quickly.
strokeColor defines the color of a line or polygon boundary. Stroke color helps distinguish geometry visually on a map.
fillColor defines the interior color of polygon geometry. Fill color helps represent areas clearly and consistently.
An API is a structured interface that allows software systems to request and exchange data. Atlasemoji APIs allow geographic datasets to be accessed programmatically.
An endpoint is a specific URL used to request data from an API. Endpoints define how software interacts with structured geographic information.
JSON is a structured text format used to store and exchange data. GeoJSON extends JSON so geographic structure can be represented and shared consistently.
