Very well done. I'm a retired University Professor who earlier taught geologic mapping with arcMap. Now I'm trying to convert to Pro and your series was just the ticket. Next may I suggest a tutorial treating orientation data--bedding attitudes, lineations, etc.-- and their symbology. Cheers, Rudy Slingerland
A tip for adding features with their symbology intact to a Local Scene: Go to your Map View. Select the feature class name you want in the Contents Pane at left. Click-Hold-Drag the feature to the Local Scene tab at the top of the map window and continue holding until the map window switches to the Local Scene (you'll initially get a ghostbusters icon but continue to hold), then Drop the feature onto the map window. It should import the feature with the symbology from your Map View! You can select multiple features at once doing this too.
We do not have lidar data for India, but there are many 30m+ resolution datasets available that cover India: portal.opentopography.org/dataCatalog?group=global
I've gone through all 10 videos and in my humble opinion, they're very well done. Full of tips and advice for beginners and professionals alike. Well done
Hello. Thank you so much for the tutorials. I have a question, for hydrological processes should we use the raster with bilinear or nearest neighbor interpolation?
Hydrological calculations will use different methods depending on what process is being modelled. ArcPro has many built-in hydrology toolboxes! Nearest neighbor is not recommended for projecting elevation data, because it often results in blocky or blurry artifacts. Projecting the DEM using bilinear interpolation to new PCS, as shown in the video, will not effect future hydrologic calculations from the DEM (ex. calculating stream flow accumulation/direction, or watersheds). Hope this answers your question! _Daniel
I would be far more likely to actually sign up to this website and recommend to colleagues if there was a straightforward way to get 32 bit per pixel height-maps, or really, any height-maps.
@surihjagirani3336 0 seconds ago Hi can you please share this tutorial of this river how to download data and draw map like this. Thanks waiting for your reply
Thanks so much for posting this webinar series! Starting to go through them now and learn more about how to use the tools your organization has developed! Recently started a new position as a geospatial data scientist, but without much prior experience with this type of data (point clouds/rasters) and this video was a great overview and gives me ideas of how we can process more data efficiently with your developed workflow. It is amazing the different applications users have found for your tools and products, and I look to do the same!
I am having troubles contributing to OpenTopography. My verification email instructs me to access myAuthorazation tab in myOpenTopo but I cannot find the tab
Hello. If you are having trouble creating account please see: opentopography.org/faq-page#t16n3471 It has some tips about things to try/check to make sure you get your registration email. In particular, you should turn off the automatic translation function of your browser as this often can cause problems.
@@MH-it3se “before common era” is dumb. The dating system that everyone uses today was created by Catholics almost 500 years ago. It’s an oxymoron to teach history while simultaneously hiding it. You don’t have to believe in Jesus to recognize B.C
You can make REMs manually via a GIS or using the python RiverREM package we developed. See: opentopography.org/blog/new-package-automates-river-relative-elevation-model-rem-generation
I am researching the subject. Is SIFT not only one type of feature detecting descriptor (from literature the best) that can be used in SfM, and that it is many other descriptors that can be used? I think that your statement about SIFT is not correct.
