Answer: Geography has become more scientific, quantitative and technology-based, and more applied to solving human problems.
- Quantitative revolution: use of statistical methods, models and theories instead of only description.
- Remote sensing: satellite images and aerial photographs give up-to-date data about land use, crops, forests and disasters.
- GIS and GPS: Geographic Information System software is used for mapping, analysis and planning; GPS gives exact location.
- Applied geography: urban and regional planning, disaster management, environmental impact assessment, resource management.
- New branches: environmental geography, medical geography, behavioural geography, welfare geography.
- Interdisciplinary approach: geography now works closely with economics, sociology, environmental science and computer science.
