The physical features of land surfaces, including relief (altitude, slope, etc.) and the location of both natural and human-made objects.

Data collected directly in the field by surveying, measuring, and recording features.

Data that already exists and has been collected by someone else, for example, maps, aerial photos, and satellite images.

Using technology to automatically convert maps or aerial photos into digital data that can be used in a GIS.

The process of organizing spatial data in a structured way, including defining relationships between features, like roads connecting to intersections.

Data about real-world features stored as points, lines, and areas (polygons) in a GIS.

Data about real-world features stored as grids of cells, each containing a value, like temperature or elevation.

The collection of data from sources like maps, aerial photographs, satellite imagery, and field surveys, which is then used to create and populate geographic information systems.

The amount of time it takes light to travel from a sensor to a target and back, allowing for the creation of 3D representations.

Data acquired by recording the electromagnetic radiation that is reflected or emitted from the Earth's surface.

A type of sensor used to capture data from space, which can be active or passive.

A representation of the Earth's surface using a series of lines, each representing a specific elevation.

A representation of geographical features and their relationships using points, lines, and polygons.

High-resolution images taken from aircraft, often used in GIS for detailed mapping.

A geographic information system is a computer system used for capturing, storing, analyzing, and managing geographic data.

A method of capturing information using a sensor that beams light towards target and measures the reflected light, allowing for a depth measurement.

A type of data format for representing spatial data, often used for engineering and CAD applications, but can also be used in GIS.

A file format specific to GIS software, which is used to store spatial data as features, points, lines, and polygons.

A collection of geographical data that is organized and managed for easy access and analysis.

A government agency responsible for providing and managing topographical data in Malaysia.

A process of converting maps, aerial photos, or other visual representations into digital data that can be used in a GIS.

A government agency in Malaysia that is responsible for collecting and providing meteorological data.

A government agency in Malaysia that focuses on environmental data and monitoring.

Converting existing data from paper or other physical formats into a digital format that can be used in a GIS.

A method for converting analogue data to digital format using a dedicated device that scans images and creates a digital representation.

A method for entering attribute information into a GIS by typing it directly into a computer, typically used for data that is only available in paper form.

Using a specialized device to manually trace the outlines of features on a map or aerial photograph, producing digital vector data.

The process of converting analogue data to digital data using automated technology to trace and extract features from maps or aerial photographs.

Existing digital data, like maps, satellite imagery, or data from previous GIS projects, that can be directly integrated into a new GIS analysis.

Data that includes numerical values, often represented in tables or spreadsheets, used to describe and analyze geographic features.

The process of organizing spatial data in a way that defines relationships between features, like roads connecting to intersections.

A method of digitizing where points are placed at regular intervals, with extra points added around complex features.

The method of digitizing where points are placed manually by the user. It can be affected by human error, causing inaccuracies.

The errors that can occur when manually digitizing, particularly when capturing winding lines. This can lead to inaccurate representations of features.

The errors that can occur when manually digitizing due to human hand movements. This causes the digitized points to be slightly off from their actual locations.

The process of converting maps or aerial photographs into digital data that can be used in a GIS. It can be done manually or with automated tools.

The process of editing and building spatial data to ensure that topological relationships are maintained. For example, ensuring that roads connect correctly to intersections.

A spatial relationship between GIS features, defining how they are connected. It defines the way the computer understands the relationship between elements, like roads and intersections.

The method of converting raster data to vector data. It uses algorithms to recognize patterns in images and transforms them into line features like roads or rivers.

The process of converting existing maps or images to digital data. It can be manual or automated, and requires careful attention to ensure accuracy and maintain topology.
