Progress and Poverty: Launching CivicMapper: Visualizing Land Values in 3D. “Today, we are thrilled to launch CivicMapper, a new interactive tool that brings cities to life through 3D visualizations…. CivicMapper lets you explore geospatial data as extruded 3D bars, each representing the land value or property characteristics of every parcel in a city.”
Are you a user of the Dutch national supercomputer Snellius?
And are you doing data visualization on Snellius itself, or copying output data from Snellius to locally visualize?
Then please fill out our "Data visualization as a Snellius user" survey!
