[Qgis-user] Tectonic plate boundaries
Hi New to QGIS. I want to plot Victorian submarine telegraph cable interruptions under the Atlantic. I know, what an Anorak!! I have found a brilliant rasterfile of the seabed from GEBCO to use as a base layer. I have also collected all the data of cable failure, submarine earthquakes and volcanoes and am ready to make vector layers of all the data. But what I can't find is a shapefile of the tectonic plates boundaries, just the boundary lines with no shading or text. Everything I do find is rejected by QGIS as not being in a suitable format. Help please!

How exciting! If you can, please share the map if you are done. This sounds fascinating :) Am 13.08.22 um 18:37 schrieb John Moyle via Qgis-user: Hi New to QGIS.

Generally the way QGIS (and most GIS) works is they "take" only data such as points lines and polygons and then the user develops styling on those to create the desire cartographic effect. It would be most unusual to find shading or text in a shapefile. Test in a shapefile is an attribute of some geometric feature. So line 377 might have an attribute that is "Mid Atlantic Ridge". QGIS provides the ability to print the text attributes as labels, which can be styled in many useful ways for visualization purposes.

Re: [Qgis-user] Tectonic plate boundaries
Hi John, Here is a GitHub site with plate boundaries in several GIS formats, including Shapefile and GeoJSON. https://github.com/fraxen/tectonicplates These should work with QGIS.

Re: [Qgis-user] Tectonic plate boundaries
Thank you one and all with helpful suggestions about finding a shape file of tectonic plate boundaries. Having tried several of them, QGIS accepts them and allows me to set colour type and thickness of line etc but even if they are the only layer selected I am unable to *see *them. I must be doing something wrong! Maybe it's "old dogs and new tricks" at 77 to learn QGIS. The problem is that this is probably the only time I will ever be using a GIS and all the courses available want to teach so much general GIS before the little bits that I need to learn!! I have my base raster file of the North Atlantic and have learned enough to make individual layers of cable interruptions, sub-sea volcanoes and land-slides etc. but have come unstuck at an *imported *shape file! Anyway, many thanks one and all.

Re: [Qgis-user] Tectonic plate boundaries
Hi John, I think you may be working with a 'Line' layer so you can't fill the space between them. You should get a 'Polygon' layer, specifically the 'PB2002_plates' from the repository mentioned earlier. You can download it from https://github.com/fraxen/tectonicplates/blob/master/GeoJSON/PB2002_plates.json [https://github.com/fraxen/tectonicplates/blob/master/GeoJSON/PB2002_plates.json] (right-click and Save As on your computer) and drag and drop it in QGIS. I also have a detailed step-by-step tutorial that shows how to import and style data in QGIS, including the tectonic plate boundaries layer that you are interested in. If you work through the whole exercise, you will have a good idea how to import several types of data to QGIS and create a map. https://courses.spatialthoughts.com/introduction-to-qgis#creating-maps [https://courses.spatialthoughts.com/introduction-to-qgis#creating-maps] --- Ujaval Gandhi Spatial Thoughts www.spatialthoughts.com [http://www.spatialthoughts.com] [data:image/gif;base64,R0lGODlhAQABAIAAAP///wAAACwAAQABAAACAkQBADs=3D] On Fri, Aug 19, 2022 at 3:15 PM John Moyle via Qgis-user wrote: > Thank you one and all with helpful suggestions about finding a shape file of > tectonic plate boundaries. > Having tried several of them, QGIS accepts them and allows me to set colour > type and thickness of line etc but even if they are the only layer selected I > am unable to see them.

Maybe one layer or the other doesn't correctly specify a CRS? If you click on Help on the main menu, which pops up the documentation for the version you are using in your browser, you can go to the section on "Working with Projections" (it's § 10 in my QGIS version). There you will find a gentle explanaton of the topic and how to problem-solve when something goes wrong.
