GIS and remote sensing are two interconnected disciplines that research the planet and its environment using geospatial data and technologies. You can take the following actions to begin using GIS and remote sensing:
1.Learn the fundamental ideas and theories of GIS and remote sensing. The fundamentals of these fields are covered in a number of online tutorials and courses, including Remote Sensing Education | Resources for Teaching Imagery by Esri, Machine Learning in GIS and Remote Sensing: 5 Courses in 1, provided by Udemy, and Tutorials | Centre for Geographic Analysis by Harvard University.
2. Learn how to use the GIS and remote sensing analytic software and equipment. There are many open source and paid options available, including QGIS, ArcGIS, ENVI, ERDAS Imagine, Google Earth, and R. Online resources like WorldMap, Google Maps, and ArcGIS Online are available as well for accessing geospatial data and services.
3. Apply your knowledge and abilities to challenges in the real world by practising them. You can find various datasets and projects that are relevant to your objectives and areas of interest, such as environmental monitoring, emergency preparedness, urban design, or wildlife protection. You can also join online groups and forums like Stack Exchange, Reddit, or LinkedIn that discuss GIS and remote sensing resources and experiences.
These are some basic basic steps to getting started with GIS and RS journey. I sincerely hope you find them helpful and enjoy finding out more information about these intriguing topics.
