This is the home for Professor Steve Crook's tutorials, notes from the field, lecture videos, and some random videos featuring travel and the outdoors.
I share videos that include GIS and Remote Sensing topics & tutorials, Physical Geography lectures & videos from the field, and the occasional Travel and Nature video from my outdoor adventures.
Access to most videos will be limited to direct links for currently enrolled students, but some tutorials and general interest topics will be publicly available.
Great video! Thanks. I want to add that I had an issue when clicking run at composing option, but it was easily solved by adding the suffix ".tif" to the resultant raster name. I appreciate this tutorial, as it's brief and made for people with some ArcGIS Pro experience. I heard there's a beginner's version, too; great job. Greetings from Chile
Thanks for the kind words and the helpful detail on the name. I think that'll happen if you save it outside of a geodatabase... and it'll work if you save it to a geodatabase (like the default path?) Not sure about that... but any chance you saved it to some other folder?
Hello, I followed your video on remote sensing basics and image classification in the context of GIS with great interest. I find your explanations particularly clear and instructive. While watching this video, a question came to mind: do you think it would be possible to find a thesis topic with a physics emphasis that could be applied in the field of GIS, especially in the context of processing images obtained through remote sensing, or even in remote sensing itself? Although I understand that currently mathematics play a crucial role in many GIS researches, I am convinced that physical principles could also offer interesting perspectives. For example, applying the laws of physics to model light-matter interactions in satellite images, or using advanced physical concepts to improve image classification algorithms. The integration of physical models into geographic information systems for a better understanding of environmental phenomena, or even the use of concepts from quantum physics (qbits - cub sats .....)/statistical physics for innovative applications in the field of geomatics? I would be very interested in your thoughts on this topic. Do you think there are opportunities to further explore this intersection between physics and GIS in the context of academic research, with possible opportunities to conduct experiments in a laboratory, for example, to improve acquisition methods (such as LIDAR)? Thank you again for the time you devote to sharing your knowledge and experience on your RU-vid channel. Best regards, AOUINATOU OUSSAMA

thank you for your videos, but do u have any kind of this lecture in pdf format ?, 'cause i prefer reading to listening though ur voice is easy to follow
🎯 Key Takeaways for quick navigation: 00:00 🌍 Remote sensing basics and image classification will be discussed in this lecture. 02:54 🌐 Remote sensing relies on the electromagnetic spectrum, including visible and infrared wavelengths. 05:27 📷 Remote sensing uses sensors, which are like cameras, to measure radiation in specific wavelength bands. 07:03 📊 Sensor data is converted into digital numbers, creating raster images with brightness values. 09:08 🛰️ Landsat satellites have multiple bands to capture reflectance in various parts of the electromagnetic spectrum. 13:45 🔵 Combining different bands in remote sensing software creates various types of color composites for visualization. 18:43 🌿 Band combinations and indices help highlight specific features and phenomena in remote sensing imagery. 23:12 🌱 NDVI (Normalized Difference Vegetation Index) is a commonly used index in remote sensing that ranges from -1 to 1, indicating the presence and health of vegetation. 24:05 📊 NDVI is calculated by comparing the reflectance in the near-infrared (NIR) and red bands, emphasizing differences in vegetation health and density. 26:21 💧 Other indices, like NWI (Normalized Difference Water Index) and MSAVI (Modified Soil Adjusted Vegetation Index), are used to assess water and soil characteristics in remote sensing.
Hi i have a problem with my Quantix Drone every chek is perfect and ok but when i click ok to fly throws an error 00008000 and stops with all red lights on. Any suggestions?
