#30DayMapChallenge Day 10 - Raster
Incoming solar radiation in Rotterdam if it wasn't cloudy now...
Tools: #QGIS with #PCRaster Tools plugin, PotRad model by Oscar van Dam available from Resource Sharing plugin repo https://t.co/DxjD8A4t5g
#OpenData: #AHN3 from @PDOK_online
#30DayMapChallenge Day 7 - Green
#greenroof potential in #Rotterdam
Existing ones, like @d_akkers show up red or orange.
Flat roofs derived from #AHN3 #pointcloud (LidarRooftopAnalysis, #WhiteboxTools in #QGIS), overlay on false colour aerial photograph. #OpenData: @PDOK_online
#30DayMapChallenge 2021 Day 3: Polygons

#QGIS w/ #WhiteboxTools plugin. #COP26
#OpenData: #AHN3 #pointcloud from @PDOK_online, #OpenStreetMap building footprints and backdrop
Animation: point cloud, hillshade, aspect
Trying the LidarDigitalSurfaceModel algortithm of #whiteboxtools to interpolate #AHN3 #LiDAR #opendata of #Rotterdam in #QGIS to a raster DSM. Hillshade blended with result from ambient occlusion tool from Terrain Shading plugin. It nicely worked for #kubuswoningen.
Rising the Dutch Mountains: combining #bathymetric (@EMODnet, @Rijkswaterstaat) and #topographic data (raster #dsm 5m #AHN3 ) with #MODIS imagery. Rendered in #Blender3D. #shadedrelief
New video: sample colours from an #orthophoto to visualise a #pointcloud in more realistic colours using #QGIS #Qgis2threejs #LAStools #Entwine #Potree. Example uses #orthophoto and #AHN3 #lidar #opendata from #PDOK. #GIS https://t.co/bgcIDaJ4mA
#pointcloud #art of @DeKuip @Feyenoord stadium with skyline #Rotterdam. Made with #qgis #qgis2threejs #potree #ahn3 #lidar #opendata and #gimp.
As a raster guy I should admit that #pointclouds are also cool. #qgis2threejs plugin #QGIS #AHN3 #opendata #lidar #potree #entwine
New video on visualising #pointcloud data in #QGIS using #Entwine #Potree and the #Qgis2threejs plugin. @ihedelft #opencourseware #AHN3 #PDOK https://t.co/jpYGf0OA9e
The skyline of #rotterdam with the #AHN3 #lidar #pointcloud visualised in #QGIS using the #qgis2threejs plugin with the new #potree support.
This new video shows how to generate a digital surface model of a city from a point cloud in #QGIS using the #LASTools plugin, generate shades with the Terrain Shading plugin and visualise in the #3D View. #DSM #AHN3 @PDOK_online #Rotterdam #gis #OpenData https://t.co/lX6SWOfPlE

@giswhisp Also spectacular in urban areas. #Rotterdam #markthal #Kubuswoningen #Laurenskerk #stationblaak #QGIS #AHN3 0.5m #DSM #opendata @PDOK_online
Last day #30DayMapChallenge, Day 30: Home. "Cool" district in the center of #Rotterdam where I live. #Coolsingel #Koopgoot #Westblaak #Lijnbaan #WTC. #opendata: 25 cm orthophoto draped over 50 cm #LIDAR based #DSM #AHN3 from @PDOK_online. Software: #QGIS with #Qgis2threejs plugin
Another fun Dutch dataset: river beds, visualized with the Dutch #AHN3 DEM in exact the same classification
Shipping canals, bridges and the silt storage (mid below) can be clearly distinguished
#hollandschdiep #moerdijk #kantelkaart
Most interesting talk at #ISPRSgsw so far: Classification of #LiDAR from #AHN3 into ground, veggies, buildings with #PointNet. For now #lasclassify still beats #deeplearning but #AI gets better fast. Considering "computational greenness" of overall processing, @LAStools wins big!
