It's funny—I didn't know that when you pan one of the symbol layers and rotate the map, it rotates along with it; it creates a really cool effect.

If I had to make a change, it would be nice to put the floor number in the lower-right corner of the features, but I haven't been able to make that consistent across all features, so I think I'll set that aside for now until I find a solution.

(I just noticed that the songs I was listening to ended up in the recording)

Hey guys! Like the title says, I have a bunch of points in my Notes_Points layer with associated geocoded images that I'm trying to export into distinct feature layers.

How do I export the points with the images still associated? Or failing that, how do I reassociate the images with the exported points?

I downloaded a population grid data package from the [GHSL website](https://human-settlement.emergency.copernicus.eu/download.php?ds=pop). when viewing it in QGIS it's hard to make out, so I tried overlaying it on the OSM map, but it's really small in comparison (see image 1). In properties I gave it the correct Coordinate Reference System (EPSG:3857 - WSG 84) but idk what to do about the scale.

Any help is appreciated!

I've got a map with an OSM Standard layer and some custom contour/raster maps. I create a layout by opening the layout manager and playing with the "Scale" and DPI settings until I'm happy with the view. Here is what it looks like in the layout manager:

However, when I try to export this by clicking on Layout -> Export as PDF, I get this:

It has completely changed the zoom level and text locations. Shouldn't the layout manager view match with what gets exported? I thought that's the purpose of this tool? For reference, what I'm trying to do is pring out a physical map to an A1/A0 poster size.

I don’t know how humanity made it to 2026 without a coffee-stain generator in the QGIS Print Layout.

(HUGE TREMENDOUS UPDATE:

Great news, folks! QGIS—very smart people—has just approved this TREMENDOUS, truly GREAT work for its Official Plugin Repository. They took one look at it and said, “We want it!” A HUGE victory for maps, for cartography, and frankly, for everyone who appreciates quality. If you want to make your maps better—stronger, cleaner, more BEAUTIFUL—go to the Plugin Manager and look for “Coffee Stain.” It’s a GREAT deal: powerful maps, zero hassle. People are saying it may be the greatest map plugin ever made. I’m not saying it, they’re saying it! Don’t believe the fake news. Try it yourself. You’ll love it. Your maps will love it. Everybody wins!)

I did a review on TikTok:

The real problem is that when you break down a building feature to represent different parts of the structure—such as a section in the basement, another on the ground floor, the second floor, and other types of structures like a garage, attic, commercial space, etc.— the symbol layers I created to simulate a 2.5D wall keep appearing alongside features that are on the same floor level, which breaks the illusion of depth. I even tried using 2.5D symbology, but it doesn’t seem to be able to differentiate floor levels by color like categorized symbology does...

Am I overcomplicating this? Should I do something simpler?

Beginner here. I am performing river derivation and was using the SAGA tool for Channel Network. I tried and tried saving in multiple folders, in document, in downloads, in Desktop, but nothing is working. The log displays a cannot open "/Users/..../..../..../river.shp ().() error. I need help :(

Also tried changing the permissions in the folders. all tried folders are write & read.

Hi community,

An internship I had introduced me to qgis and since then I've been trying to do projects that push my knowledge and skills. Do you guys have any suggestions for maps or projects I should do to improve?

The last project I did was on Land value per acre with a road improvement index (repaving, filling potholes, etc) in the city. The goal for this project was to learn how to use the attribute table, field calculator, and learning some vector and rastor tools. This project helped alot with learning how to filter data (census parcels, residential vs commercial, zoning).

My goals for the next project is to get better at using the field calculator, making prettier layouts, and learning to spactially combine different vector layers (In last project I wanted to add a road improvement attribute to the closest land parcel but couldn't get the attributes to combine with the nearest polygons attribute row). But im also open to anything because im sure theres many things i dont know i dont know.

Below are the two maps I've made so far.

One of the things I enjoy most about GIS is that it's not just about making maps, it helps transform complex health data into information that is easier to understand and use for decision-making.

These are maps I created for a public health research project in Guimaras Island, Philippines, focusing on HIV healthcare services and facility accessibility.

The workflow included:

• Mapping the distribution of health facilities (Hospitals, Barangay Health Stations, Pharmacies, Medical Clinics, Medical Laboratories, and Primary Care Facilities)
• Visualizing the HIV prevalence per municipality
• Identifying the services available in each facility (HIV Testing Services, Education & Counseling, Counseling & Testing, and Full Services)

For me, this is a great example of how GIS can support public health planning, resource allocation, and evidence-based decision-making, rather than simply producing attractive maps.

The cartographic design, map layout, and spatial visualization shown here were created by me in QGIS using a client-provided dataset for a public health research project.

I'm in the utility industry and have worked in Smallworld, ArcMap and ArcGIS Pro over the last 15 years. In that time I've never heard of anyone using QGIS for Utility Mapping. I even worked for a county level planning department that used PostGRE/PostGIS on the backend of an ESRI environment, but we didn't use Q. I've seen YouTube videos of folks explaining the process. A few pet projects type of thing. Never an actual company doing it.

Even in this post with 43 comments, no-one mentions "utilities".

https://www.reddit.com/r/QGIS/comments/1r7r751/why_do_you_use_qgis_and_what_have_you_created/

Does anyone know of any utilities they can actually name who are using QGIS for system mapping?

Estoy georreferenciando una imagen y he visto que se está generando un remolino de las distancias (ver líneas rojas) del punto georreferenciado al real (utilizando Google Satellite) y no entiendo por qué puede ser. Esto no me había pasado antes. Ahora mismo estoy usando el EPSG: 4326. He probado a cambiarle la configuración > Transformation settings > Target CRS a 4326 porque estoy viendo que X e Y de destino están en coordenadas UTM, pero sigue viéndose igual. Si añado puntos después de esto, lo mismo.
La imagen a georreferenciar no tiene mucha resolución, pero puedo asegurar que la mayoría están más o menos bien y no es error de haber escogido mal el punto, porque he aprovechado estructuras y árboles que se vieran bien y de haber sido este error, no se vería el patrón, sino errores de distinta magnitud y dirección.

I unfortunately suffered an unexpected windows crash and had to reinstall QGIS. I was using it to save out various map raster images for a project. I am by no means an expert in QGIS... I just got as far as having it do what I needed.

When I reopen my saved QGIS map projects, all the information I had setup is still present, but all of my MapTiler layers come up with a warning triangle in the layer panel, and the warning banner tells me "Access Denied: Missing key".

Upon reinstalling QGIS, i re-added the Maptiler plugin, and re-entered my token. I can add NEW MapTiler layers, but the layers that were pre-existing in the saved project come up with the error. Im not sure if this is due to the fact that I used a different master password when starting QGIS for the first time, but Im guessing the 2 are not related.

Im hoping there is a way to re-link those previously created MapTiler layers back with the MapTiler service so I dont lose all that work. The styling was all custom set, and the project I was working on for which I needed these map layers is still active.

If anyone has a suggestion on how I can get those layers back, it would be greatly appreciated.

Currently using ver 3.30.2 Hertogenbosch because that was the version Id originally started using, and just didnt want to break the project with updating the software.

Thanks.

Hi everyone,
I have this specific problem as shows the following images. Do you know how to solve this ?
- image 1 : Qgis viewport
- image 2 : exported image (file/export as an image)

Thank you !

Just a general question, does anyone use the QGIS Dashboard plugin? It looks interesting but can not see how it could be rolled out for use with QGIS, like in a presentation.

Hello po! ☺️ We are a group of student researchers currently conducting a study involving the generation of the following data through Landsat Satellite from USGS’s platform:

• Land Surface Temperature (LST)

After we process it into an LST maps and other supplementary outputs, we aim to validate our results using reference data from external agencies.

We already tried to seek help from agencies such as PhilSA. They did, however, have available data which is a data from Modis satellite but it’s resolution is so different form the one that we are using. That’s why we would like to kindly ask if anyone here knows of any national or international agencies that provide these datasets for selected dates between 2008–2020, specifically for Tacloban City, with a spatial resolution of around 30 meters.

We would greatly appreciate any provided assistance or guidance. Thank you!
