| Aug 3, 2020 at 16:56 | comment | added | MapDeath | Irrespective of whether the solutions posed actually worked (I'm still testing them), this question is specifically for biodiversity maps. Some people wouldn't know to search for "overlapping geometries" if they are biologists new to QGIS | |

website added for IUCN

| Jul 29, 2020 at 5:07 | comment | added | MapDeath | Yes that is the website, and I'm trying the directions from the first answer on that other stackexchange question but QGIS Union is spitting an error at me about a problem with overlapping at a point in Antarctica, even though none of my shapefiles are in Antarctica | |
| Jul 29, 2020 at 4:38 | comment | added | Miro | And I believe this question gives you complete guide on how to sum up values to visualize the layer the way you want: gis.stackexchange.com/questions/210959/… | |
| Jul 29, 2020 at 4:22 | comment | added | Miro | iucnredlist.org/resources/spatial-data-download - I suppose this is the download website link which took me a while to find. | |

added IUCN.org as a place to download an example shape file with multiple polygons

| Sep 12, 2019 at 18:43 | comment | added | csk | It sounds like you want to count the number of polygon each overlapping area. There's a good answer for that question here (for your purposes you can probably skip the final step of rasterizing): gis.stackexchange.com/a/297334/81764 | |
| Sep 12, 2019 at 9:19 | comment | added | Babel | If I understand you well, you want the color to become more intensive (or darker, or brighter, whatever...) with increasing value in your subclasses. Your problem with graduated style is that you just have random colors but not this effect of increasing intensity of a color-scheme, is that right? Than you should try to change the color-ramp (like from blue to yellow, as in your screenshot) in graduated style and try different settings for classification. | |
| Sep 11, 2019 at 2:44 | comment | added | MapDeath | I thought about that but that didn't work. I'm working with a single shape file that has a number of subclasses. When setting style to graduated it just changes each of the polygons to a different color. It doesn't do addition of all the overlapping polygons | |
| Sep 11, 2019 at 2:35 | comment | added | csk | that map looks like the "number of species" polygons have a graduated style, and there's a country boundary layer overlaid on top | |
