Study Notes
Spatial Science and Geographic Information Science
- Spatial science, also known as geographic information science, seeks to understand, analyze, and visualize real-world phenomena according to their locations.
- Spatial scientists apply technologies such as geographic information systems (GIS) and remote sensing to spatial data.
Big Data and Spatial Data
- The current era of big data generates real-time spatial big data from sources such as geotagged social media posts and environmental sensors.
- At least 80% of all data are geographic in nature, making up 80% of the 2.5 exabytes (2,500,000,000 gigabytes) of big data generated daily.
Spatial Data Science and GeoAI
- Data science and spatial data science are evolving fields that provide methods to organize and approach generating new knowledge from spatial big data.
- Geospatial artificial intelligence (geoAI) combines innovations in spatial science with artificial intelligence (AI) and machine learning to glean meaningful information from spatial big data.
Artificial Intelligence (AI) and Machine Learning
- AI refers to machines that make sense of the world, automating processes to create scalable insights from big data.
- Machine learning is a subset of AI that focuses on computers acquiring knowledge to iteratively extract information and learn from patterns in raw data.
- Deep learning is a cutting-edge type of machine learning that draws inspiration from brain function, enabling computers to learn from experience and understand the world as a nested hierarchy of concepts.
Data Mining and Applications
- Data mining refers to techniques to discover new and interesting patterns from large datasets.
- Applications of data mining techniques include recommender systems and cohort detection in social networks.
GeoAI Applications
- GeoAI applications include deep learning architectures and algorithms for feature recognition in historical maps, multi-sensor remote sensing image resolution enhancement, and identification of the semantic similarity in attributes for OpenStreetMap.
- GeoAI is being used in environmental exposure modeling, providing methods to measure new exposures that have been previously difficult to capture.
