Creating 3D models for QGIS with ODM on Windows
This post is a walkthrough showing you how to create a 3D model using ODM and Blender from the video frames of a video shot on your cellphone and use the 3D model as a symbol in QGIS. Blender is a free and open-source 3D creation suite. Open Drone Map (ODM) is drone mapping software that can be used to generate 3D models from aerial images (or in this case, generate 3D reconstructions from cell phone video). This post is adapted from Creating 3D Models for QGIS With ODM by Tim Sutton, which describes how to achieve the same results on Linux.
QGIS STAC API Plugin
A new QGIS plugin that allows browsing STAC API catalogs inside QGIS has been released. The plugin, developed by Kartoza and sponsored by Microsoft, is available for download and installation in the QGIS official plugin repository. Before this plugin was developed, there was an existing plugin that aimed at providing the same services, though it wasn't updated to use the latest stable release of the STAC API and was not being actively maintained.
Collaborating on a QGIS Project saved in a PostgreSQL database
QGIS provides a couple of options when it comes to working with QGIS projects. All these formats have their strengths and weakness. When doing some work in QGIS we used to share around the QGIS projects but ever since storing the QGIS projects in a PostgreSQL database became an option we have been investigating using this as our primary method of collaboration.
A step forward in Kartoza's QGIS and GeoNode Training
Learning online has become an essential part of education globally. Kartoza has answered the call for up-to-date, engaging and dynamic teaching material by updating our QGIS and GeoNode teaching platforms. Kartoza uses our open source 'changelog' platform, that allows for continual updates and customisation of material to deliver cutting-edge training.
The Kartoza Intern's journey creating a field survey with QGIS, Mergin and Input
Simple, powerful and efficient field data collection is vital for any project with a geospatial aspect. Input is a FOSS application created by Lutra consulting that brings the power of QGIS to a portable device for data collection. The Kartoza intern team was challenged to get to grips with Input. The team decided to keep it simple and create a project to collect data from local parks, including paths, trees and infrastructure. This blog follows the journey taken by the team and includes tips and tricks to help novice users.
QGIS Road to Nerdvana Episode 19 and 20
Today's blog shows the next two episodes in the Road to Nerdvana series. Episode 19 is a walk through using the Google Earth Engine Time series Explorer plugin for QGIS.
QGIS Road to Nerdvana Intern Edition
The interns took over the Nerdvana space, showing off their mapping skills using QGIS
QGIS Road to Nerdvana Episode 18: Introduction to PostgreSQL and PostGIS
This is a walk-through showing how PostgreSQL and PostGIS can be used as a geospatial data store and then the data in that store be consumed and created by geopandas.
QGIS Road to Nerdvana Episode 14: Fun and games with QGIS Server
In this episode, Charles and Tim walk through setting up a QGIS server in docker with data and QGIS project files published in PostgreSQL / PostGIS. They have made a resource pack with the configuration files created and the sampled data etc., all of which are available at:
QGIS Road to Nerdvana Episode 12: Dashboards revisited!
In case you missed out on Episode 12 of our QGIS Road to Nerdvana, click on the link and enjoy the stream:
QGIS Style Sharing Repository
Woohoo! A new way to share styles in QGIS! Work sponsored by Kartoza.
QGIS Road to Nerdvana Episode 11: Aggregate dashboards
Tim Sutton decided to change things up a bit, he was joined by Charles and Seabilwe from Kartoza and the three made aggregate dashboards in QGIS. It is just the first steps and a lot of bumbling around, but hey, maybe you will learn something!
QGIS Road To Nerdvana Episode 10: Speed Map Making (part 2)
Why make just one map in the quickest time possible? Make more! In this video, Tim Sutton will again try to go from Zero to a Nice Looking Map as quick as he can.
QGIS Road to Nerdvana Episode 10: Speed Map Making (part 1)
In this video, Tim Sutton will be trying to go from Zero to Nice Looking Map as quick as he can. See how he goes about creating the map and see if you can't make a nice looking map in 30 minutes.
QGIS Road to Nerdvana Episode 9: Building a 3D scene from scratch
In this episode, Tim Sutton will show you how to make a simple 3D scene in QGIS.
QGIS Road To Nerdvana Episode 8: It's all a big meshunderstanding
In this episode, watch along as Tim Sutton explores some new mesh capabilities coming in QGIS 3.16!
Finding and fixing topology and geometry errors in QGIS
Google Maps, Google Earth, Uber are examples leading software/apps that are driven by GIS. They have allowed the ordinary person inadvertently to use GIS and appreciate its power without needing an understanding of the basics of GIS. Many people have taken the leap to using GIS by using some of the GIS capabilities in Google Earth.
QGIS Road to Nerdvana Episode 7: Logging Postgres Calls
In this episode, Tim Sutton will show you how to enable PostgreSQL logging and what underlying queries are generated by QGIS or any other PostgreSQL client.
QGIS Road to Nerdvana Episode 6 - Responding to feedback on Episode 5 Pull Request
This episode is a follow-up from Episode 5, responding to the feedback received.
QGIS Road to Nerdvana Episode 5: Tweaking the first run dialog
In this episode, Tim Sutton takes you along for the ride as he picks a long-time irritation in QGIS: The first run dialog. He tweaks it to make it look nice to submit it as a pull request to QGIS.
