Annotation
Text or graphics added to maps to provide additional information about spatial features (inferred from standard GIS usage).
What is Annotation?
Annotation refers to the textual or graphical labels added to maps, images, or datasets to provide explanatory information or highlight important features. In mapping and GIS, annotations help users understand the content by identifying place names, landmarks, boundaries, or specific data points.
For example, on a map, annotations may include names of cities, road numbers, elevation values, or notes about a particular location. Unlike regular labels that are automatically generated, annotations are often manually placed to allow for custom positioning and styling, making the map more readable and informative. Annotations play a crucial role in enhancing the clarity, communication, and interpretation of spatial data.

The process of marking or categorizing unprocessed data, including text, audio, video, or photos, so that computers can comprehend and learn from it is known as data annotation. It is an essential phase in training AI and machine learning models so they can identify patterns, forecast outcomes, and do jobs precisely.
The practice of marking or tagging areas, objects, or features in an image so that computer vision models can understand it is known as image annotation. In order to ensure that robots can correctly interpret visual data, it is an essential stage in training AI systems for tasks like object detection, image recognition, and autonomous navigation.
Software or features that let users annotate photos, papers, maps, or datasets with notes, labels, highlights, or other descriptive information are known as annotation tools. By making important information understandable and readily available, they improve comprehension, teamwork, and analysis. These tools are commonly used in document review, education, GIS, and AI data labelling.
The technique of identifying or tagging text data to make it machine-understandable is known as text annotation. In order to train AI models in natural language processing (NLP), sentiment analysis, and information extraction, it entails locating entities, keywords, sentiments, or other pertinent information inside the text. Annotating models correctly increases their correctness and facilitates the automation of processes like data analysis, chatbots, and search engines.
