planlauf/TERRAIN – a lightweight 3D DEM viewer for daily usage

The visualization and interpolation of 3D terrain (point) data (DEM or DOM) could be a hard task for current GIS software and small to midsize hardware. One thing is the huge possible amount of points and their precision when it comes to airborne or terrestrial LIDAR data with point density < 5m and big areas of interest. Another thing is the rendering performance once the user started his exploration of such a huge dataset. There are several open source and proprietary software solutions and specialized software for several industries. In the following I’ll introduce you to planlauf/TERRAIN, a lightweight DEM…

Mapalomalia: First web geological modeling platform

Mapalomalia lets geologists create and visualize 3D geological models from their browsers. It’s a free to use geological modeling platform. I hope people will use it to convey information about our planet that helps humankind to tackle big problems and at the same times makes geological modeling easier. I have developed it with input from many geologists, and by releasing it early I hope to receive more input from many more geologists. Just sign up here to start creating models.

ArcGIS Earth

When I visited university (I have t admit, this was some years ago 😉 ) I was told ArcGIS cannot “do” 3D. This was the part where CAD enters the arena… But time goes by and together with ArcGIS 10.4. we will get 3D as it is meant to be.

create 3D visualizations: QGIS, GRASS and NVIZ

3D is soooo cool… Okay let’s be honest: the exciting times of Second Life are gone and the Oculus Rift is still not in sight in the end-user stores. But it is and was always cool to create you own 2.5D (we are using GIS not CAD, you know) visualization and make beautiful graphics for your papers or posters. It was always a big drawback for QGIS that ArcGIS was and is so good with ArcScene. But we’re proud users and we’ll use NVIZ. Let me show you how.

Maps for our robots

I have often wondered what could be the purpose of these mapping 3D models more and more accurate for major cities of the world (eg, Monaco, Geneva or Dubai). The level of detail provided by the standard City GML even imagine the level of detail taking into account the interior (Level Of Details-LOD4) architecture, street furniture, and even the vegetation with its growth and seasonal aspects . Applications in architecture and urban planning are obvious, but beyond … These models increasingly geographically and geometrically accurate (absolute GPS positioning errors of the edges and vertices of the order of 5 to 10cm…
