please, is this the same as forest fire maps? How can I get forest fire maps for different indices, e.g., NBR, NDVI, etc.? Also, was there any atmospheric correction done on this?
Yes you can do this for forest fire assessment. You can use same landsat satellite other bands to estimate other indices. Check my oldest video you will get all information.
Thanks for the breakdown! 🤔 Need some advice: 🙏 I have these words 🤨. (behave today finger ski upon boy assault summer exhaust beauty stereo over). Not sure how to use them, would appreciate help. 🙏
Jobs in GIS sector is good in India and in abroad also. as its a booming technology may in future you will get more opportunity. Only you need to upgrade the IT skill with that will be advantage.
@@spaceremotesensingandgis5626 Thank you for your reply. I am very very confused to decide from BIM (Building Information Modelling) Or GIS/GPS. I have searched Khagolam institute for GIS.. in Mumbai. But for that it related they have 1 year course. And I have 2 years gap. Please tell me what to do now.
How do I get the Hansen global forest loss dataset into ArcGIS pro for the Tapajos area in Brazil? I am looking at road network impact on deforestation and have been told to use the hansen data. How do I get this in and be able to obtain tree loss data per year?
To analyze deforestation changes over time, you can use satellite imagery from different years. A good approach would be to download historical data, such as Sentinel or Landsat satellite images, from the year you want to examine for deforestation. Afterward, download the most recent images from the same area. By comparing these two datasets, you can assess the changes in forest cover and estimate the extent of deforestation over time. Tools like remote sensing software (such as ArcGISPro, ENVI, or Google Earth Engine) allow you to perform change detection analysis, where you can quantify and visualize the deforestation between the two time periods. This method provides a clear, data-driven understanding of environmental changes, helping inform conservation efforts.
Did you digitize the water polygon? I'm curious where you obtained the water polygon. I watch the first part and did not see where this came from. I know you obtained the sea level rise from Living Atlas, but curious about the water poly. I don't want to draw this to delineate water if I don't have to.
I already have the water polygon for the sea, but you can generate a new sea water polygon using various water extraction techniques. These methods involve processing satellite imagery to identify and extract water bodies, allowing you to create an accurate polygon representation of sea water. Techniques such as spectral water indices (like the Normalized Difference Water Index, NDWI) or classification algorithms can help in isolating sea water areas from other features in the imagery. By applying these techniques, you can refine or update the sea water polygon based on more recent or precise data.
High-resolution satellite images from before 1990 are generally not available. However, if you have access to aerial photographs from that period, it would be possible to extract building information from those images. Aerial imagery, often used before the era of advanced satellite technology, can provide detailed views of the landscape, including buildings. By using modern image processing techniques, you can analyze these aerial photos to identify and extract the structures within the area of interest
How can I convert the result to a feature layer with time, in order to use this simulation with a time slider in the ArcGIS API 4? Can you create a video tutorial for this?
Hi Sir, thanks for this video. I downloaded 5-year annual rainfall data for my AOI from CHRS and calculated the average rainfall. Can I still use the method "Convert Raster to point data; Interpolation (IDW)"? Would my output map still be 'Average Annual Rainfall' map? Thank you.
Can you explain me if this process is also helpful for glacier velocity estimation? Kindly reply as early as possible? And if you can help me with glacier velocity estimation using sentinel 1 data on SNAP, it will be very helpful for me. If you want we can also discuss the same via email also.
When I try to open the manifest.safe file in ArcGIS pro it showed a failure to open/ unsupported data type. How do you think I could fix this error? thanks
can you share PDF of this session... I was also there in the GIS for Climate Change MOOC... Somehow, I deleted that PDF. Really appreciate and its URGENT
I followed the process but when I composite the bands it came as follows Red band-1 Green band-1 Blue band -1 And when I expand it still comes the same way showing all the seven bands
Thanks for your helpful video. I am attempting supervised and object-based image classification using Arch Pro (V.3.2). Here are the steps I have followed: I acquired Sentinel-2 imagery and combined bands 2, 3, 4, and 8 (10m resolution). I performed image segmentation. I created a classification schema. I generated training samples. However, when I attempt to classify using a support vector machine classifier, I encounter the following error: ERROR 003436: No training samples found for these classes: Soil, Water, Impervious, Grass, Tress. The table was not found. [VAT_Segmented_202407110934456475089_interIndex] The table was not found. [VAT_Segmented_202407110934456475089_interIndex] Failed to execute (TrainSupportVectorMachineClassifier). Failed at Thursday, July 11, 2024 9:44:52 AM (Elapsed Time: 0.22 seconds) I have tried several times but haven't been able to identify the cause of this error. Do you know what might be causing it?
Hi Sir, I couldn't understand how to add points on the map. I want to add a few points on the map just like yours from the attribute table, and want the camera to trace them in the animation. How can I do it?

Hello sir I recently watched one of your video on liss 4 data processing in arc. I am trying to analyse lulc using by liss 4 data. but it give errors after training point. Using svm. It something releted because liss 4 has only 3 bnads.
@@spaceremotesensingandgis5626 Input Radar part is not reading my IW Manifest.safe file. I have downloaded from SAR Data from copernicus. Why it is showing error?
Do not take any stress just try to learn and enjoy your work. I am sure you will do great job. First break your work in small parts and try to finish one by one. make a plan and Follow it.
