For the best part of today, I've been trying to get my head around how to install GDAL on my CentOS 8 server.

I've researched on many different answers and solutions across different sites and across StackOverflow and nothing seems to be working! (I'm probably missing something obvious somewhere)

I'm trying to install GDAL using the command pip3 install gdal

Which in return, produces the following error:

I am currently working on a product that makes use of here maps javascript sdk. As part of the project, we require the user to "draw" circles and store them as polygon within the database.

We are encountering an issue where trying to convert a circle to a polygon and back to a circle actually generates a shape is is bigger than the one before. (the reason why we do this is because the user draws a circle, we save it in the DB as a polygon, and then we reconvert as a circle in case the user wants to edit it).

I am going to try and give more context:

The following code will produce a shape with the following bounding Box:

Uber has released h3, a framework for efficiently handling big data in the geospatial file. Using h3, I attempted to get the location of a hexagonal grid location as shown in the figure. (https://eng.uber.com/h3/)

I got the location of the hexagonal grid from the following code. Then I plotted it on a two-dimensional map to see if it covered the entire earth. However, I'm not getting valid hexagons on the boundaries(-90°,90°,-180°,180°). And it doesn't seem to cover the entire globe. (hexagonal grid)

I am working with some geodata. I want to get a point object from the latitude and longitude that I already have. My code looks as follows:

Although I have read many similar articles about PointField and 'NoneType' object error, I can't figure out how this field should be automatically save according to the latitude and longitude variables I received from the user.

Here is my model:

I'd like to download inside Shiny a georeferenced PDF file (geoPDF) and for this a need some steps like convert the plot in ggplot format to tiff, populate the spatial coordinates, create a geo tiff, and finally my geoPDF. But several steps in downloadHandler() function in tempdir() directory results always in the error:

I am running an Apache Jena Fuseki server als the SPARQL endpoint that I can connect to when using the application normally. Everything works and I get the output from the resulting query.

But When I try to run my test with Springboot, Junit5 (I assume) and MockMVC it always get stuck on the following part:

This question appears to have been answered before, but none of the answers helped in my case. First I should say that I've followed the OSMnx Installation steps exactly. Then tried to run the following code in a Jupyter Notebook:

This is my first time using stack overflow so apologies if I do this wrong.

I'm fairly new to coding in R and I'm trying to make a simple Shiny app using a TidyTuesday dataset. I wanted to make a map with points showing the different types of water systems ("water_tech") and radio buttons to choose which type of water system is plotted on the map. I got the app to load without an error message, however no matter which button is selected, all of the different types of water systems are plotted on the map, not just the one I selected (essentially, the buttons don't work). If anyone has any ideas about what could be causing this to happen I would greatly appreciate it!

Reproducible code:
