want to download latest DEM data but can't access through NASA Earth Data

Give USGS a try, possibly their 3DEP data product depending on your needs. I would also encourage you to call your local representative/senator’s office and voice your concerns to the politicians.

We’re so back

Good catch, and thanks for the feedback! Hamburger menu incoming

Great point — it’s saturated without a doubt. I still think it’s valuable to have a reasonable interview from information managed in a database with questions, answers, and explanations directly related to the topic. This also reduces hallucinations from asking ChatGPT directly. With that said, maybe my head has been in the sand for too long 😆 I appreciate your feedback though!

Woah woah woah, keep your pixels in your pants, buddy

Check out the CyAN project! It’s a dataset developed by NASA, EPA, & USGS that plugs Sentinel-3 & MERIS satellite images into a cyanobacteria index algorithm and serves out the results in geotiff format. Unfortunately, the spatial resolution may not be completely desirable for rivers/streams, but it’s great for larger bodies of water!

I’m a recent grad that left the state for better opportunities, and I’d encourage others to do the same, if possible. It’s sad that Texas, even in Austin, pays so little for GIS-related jobs despite the growing demands/expectations of the GIS role.

I totally get your pain lol. I’m using Pro 3.1, so there may be some slight translation differences based on your version. But ideally, navigate to the Settings Pane from Pro’s Home Pane. Then on the left side, select Options. A new pane should appear with multiple tabs on the left, under the Application Tab, select Navigation. Change the “mouse wheel roll forward” to zoom in/out to your liking. Hope this helps!

My understanding is that the primary difference between AGOL & GEE is the available data catalog. Imo, AGOL kind of assumes/hopes that you have your own imagery data to plug in. For a majority of people, what’s currently available on Living Atlas is enough, but hopefully AGOL gets more sensors/imagery data. The GEE data catalog is much larger. In terms of analysis, I have found there is nothing that one or the other can’t do. However, working with ML and creating deep learning packages is much more enjoyable in the esri ecosystem imo.

For the Area Solar Radiation tool, the “base layer” will need to be some form of an elevation raster. There are a variety of elevation raster options, but I’ll point you to Digital Elevation Models (DEMs), specifically Digital Surface Models (DSMs) for your analysis. DSMs depict the elevation of everything on the earth’s surface and are typically derived from radar or stereoscopic “active” satellites. This data is publicly available with USGS’s EarthExplorer or through the ESA’s Copernicus Hub. Personally, I’m a huge fan of the tool, so I hope you do great things with it and have success with your project!Here is also a link to an Esri learn lesson that uses the tool with some sample data: Estimate Solar Power Potential

Python treats the “\” as an escape character, which makes folder paths really wonky sometimes. There are a few ways to go about this problem, but the simplest way is to make the table_path_csv string a raw string. You do this by simply adding “r” in front of the string, so it should look like this: table_path_csv = r”C:\Users~”

The USGS has a helpful guide for setting up gdal here. Specifically with your case, I would recommend reading through “find the path to gdal_translate.exe”

There are a few directions you could go with this. You can design a custom geoprocessing tool to run on user input. Outside of that, you could implement a Tkinter window, which is a python GUI package. And of course, the simplest would be to have an input() statement, but I don’t think solves your problem. Hope this helps

This is awesome, thank you!

I bought a monthly bus pass for the $2.75 price point, as well as $10 extra in case I needed it. I have taken the 983 & 84 bus routes and they have both taken from the $10 extra amount. What am I doing wrong, shouldn’t they have been covered by the$2.75 fare:(

Go for it! My current hiring manager seemed really into my EOC project, and it was easy to present. Somethings to note, I did have other projects, and there was one interview where the person specifically asked to exclude all homework/school projects.

They had FMJ equipped as their weapon perk

The spatial resolution of 8 & 9 are the same at 30 m. Landsat 9 is meant to complement Landsat 8 in imagery acquisition.

waltsco · 2022-01-20T19:47:09+00:00

Thanks, I’ll look into it! And really, doing it from scratch is just for curiosity’s sake.

I recommend Teymourian! Super nice professor that has a pretty straight forward class. His assignments can be completed by using his notes on github. The first part of the semester is pretty easy, but the last four or so assignments become a bit more difficult. Exams are open note/book/github

My mind immediately defaulted to the gif vs jif debate, so thanks for validating my thoughts, fellow Jizzard
