Gis exam 1 part 1

Data that includes geographic locations and attributes, used in GIS.

A data model that represents geographic features using points, lines, and polygons.

A grid-based data model composed of pixels or cells representing spatial information.

Basic vector data types used to represent spatial features.

The smallest unit of a raster dataset, representing spatial data.

A common GIS file format for storing vector data, including points, lines, and polygons.

An older GIS data format that stores spatial and attribute information separately.

A data model used to represent surfaces with irregularly spaced points connected by triangles.

The study and representation of the Earth's surface features, including elevation and terrain.

A piece of information associated with a spatial feature in a GIS database.

A mathematical representation of the Earth's shape, used in coordinate systems.

A reference system for measuring locations on the Earth’s surface.

A coordinate system that uses latitude and longitude to define locations on the Earth.

A coordinate system that projects the Earth's curved surface onto a flat plane.

A raster representation of terrain elevation data.

A line on a map that connects points of equal elevation.

The rate of change in elevation over a given distance.

The compass direction that a slope faces.

An area visible from a specific location, often used in line-of-sight analysis.

A shaded relief map that simulates sunlight on terrain to show elevation changes.

A database designed to store, query, and manage spatial data.

A collection of related feature classes within a geodatabase.

A set of spatial features with the same geometry type and attributes.

The level of detail in a raster dataset, defined by pixel size.

Categorical data that names or classifies features without a numerical order.

Data that represents a ranked order but lacks uniform intervals.

Numerical data with equal intervals but no true zero point.

Numerical data with equal intervals and a meaningful zero value.

The shortest path between two points on a sphere.

The collection of data about the Earth from a distance, typically via satellites or aircraft.

A method of linking attribute tables based on a common field.

A data type representing whole numbers.

A data type representing decimal numbers.

A data type used to store alphanumeric characters.

A data type used to store date and time information.

The height of lowercase letters in typography.

The study and practice of making maps.

A thematic map that uses color to represent data values within defined areas.

A map in which geographic areas are distorted to convey information about a variable.

The RGB color model where red, green, and blue light combine to create colors.

The CMY(K) color model where cyan, magenta, and yellow pigments combine to create colors.

GIS handles spatial data, DBMS manages databases, and CAD focuses on design and drafting.

A geographic coordinate system uses latitude and longitude, while a projected coordinate system translates this onto a flat surface.

Explicit representation directly stores spatial features, while implicit representation derives them from relationships or rules.

Define Projection assigns a coordinate system to data, while Project converts data between coordinate systems.

Cylindrical, conic, and planar (azimuthal) projections.

Site selection, line-of-sight analysis, military strategy, landscape visibility planning.

Raster format efficiently represents continuous elevation data and supports analysis like slope and aspect calculations.

A single GIS feature composed of multiple geometries, such as an island group represented as one feature.

A datum is based on an ellipsoid and provides a frame of reference for geographic coordinates.

Non-spatial data is stored in attribute tables and linked to spatial features for analysis.
