Listen to a new #podcast of #thewaterchannel where I was interviewed about #opensource #gis #remotesensing and #opendata in #watermanagement. #qgis #foss4g #osgeo https://thewaterchannel.tv/thewaterblog/the-case-for-open-data-in-water-management/

Next week #ihedelft MSc students are going on fieldwork. #gis desk study with #opendata and #opensourcesoftware is important for preparation and planning. Last September I published this free course on fieldwork preparation at the GIS #OpenCourseWare platform: https://courses.gisopencourseware.org/course/view.php?id=46 #qgis #foss4g #osgeo

Register now for my workshop on hydrological analysis with #PCRaster in #QGIS and #Python, on August 23 at #FOSS4G 2022 Firenze.

My workshop on hydrological analysis with #PCRaster in #QGIS and #Python is accepted for
#FOSS4G 2022 in Firenze. https://2022.foss4g.org.
This playlist shows some of the things I'll cover in the workshop: https://youtube.com/playlist?list=PLeuKJkIxCDj2xbV45C45wz3N89FvmTuSu

I've started my own #gis consultancy (self-employed) to deal with my #opensource GIS side activities: QWAST-GIS. Check http://www.qwast-gis.com for more info. #foss4g #osgeo #QGIS #Python #PCRaster

Join the launch of the 2nd edition of the book #QGIS for Hydrological Applications on May 19, 18:00 UTC/20:00 CEST live on my YouTube channel. The authors (Kurt Menke & me), the publisher (Locate Press), and beneficiaries of the #QGISHydro book fund (Natalia Cárdenas Niño & Celine Safi) will be interviewed by Amy Burness. https://youtu.be/JoGl4ClwZys

Besides these updates there are many others. So, get the #ebook now with $10 discount or order the hard copy that will be available soon! https://blog.locatepress.com/qgis-for-hydrological-second-edition/

This was my first thread on Mastodon, hope it works like this...

In addition to the book, I've added 60 new videos to my #YouTube channel to support you while you go through the #QGISHydro exercises in the book. https://youtube.com/c/HansvanderKwast

In Chapter 4 we've added the steps to visualise flow direction as arrows in 2D and 3D. The #Crayfish plugin by @lutraconsulting is used for this. #mesh https://lutraconsulting.co.uk/projects/crayfish/

Chapter 7 on #mapdesign now includes the use of (custom) legend patch shapes and dynamic text.

In Chapter 6 on the calculation of the percentage of land cover per subcatchment, we have added the steps to match the colours of the #dataplotly pie chart with the legend of the layer.

In Chapter 5 on adding #opendata to your catchment, we use the WMTS from the #ESA #WorldCover data https://esa-worldcover.org/en. In the first edition we used #CORINE data, but that was limited to Europe.

In Chapter 3 on #spatialanalysis with #mapalgebra, we introduce Raster Attribute Tables (RAT or VAT), which can be used in #QGIS with the Raster Attribute Table plugin developed by Alessandro Pasotti. https://github.com/noaa-ocs-hydrography/qgis-raster-attribute-table-plugin

The most important update is in Chapter 4 on stream & catchment delineation. Instead of #SAGA the workflow now uses the #QGIS #PCRaster Tools plugin, developed by Nyall Dawson
& me. https://jvdkwast.github.io/qgis-processing-pcraster/. This video explains why we switched: https://youtu.be/9fWQZqPjPVk
