New tool for clustering and analyzing spatial data with Neural Networks and Neural Gas
A new tool for clustering and analyzing geographic data with artifical self-organizing neural networks (SOM) and the innovative Neural Gas (NG) algorithms has been made availabe. The free SPAWNN suite supports different spatial context models and it also establishes interactive linkage between the neural network and geographic maps. Notably it enables further the follow-up clustering…

GIScience for Endangered Wild Plant Species
The new project WIPs-DE (“Wildpflanzenschutz Deutschland”) is part of the National Biodiversity Strategy, which has been conducted by the German Federal Agency for Nature Conservation (“BfN”). Its goal is to preserve 15 endangered wild plant species for which Germany has a special responsibility. Germany therefore has a special responsibility for those species, because they either…

Do cities make us ill? – new project on PsychoGeoinformatics
To what extend do urban environments put stress on mental health? And how can geographic information and analysis support in discovering the underlying relationships ? These are the core research questions of the new collaboration project “PsychoGeoinformatics”. The project has been accepted as a twinning project of the Center for Scientific Computing (IWR) at Heidelberg…

Sunny field trip of laser scanning course
On 7th of July, the summer semester’s laser scanning course was on a field trip for capturing a gravel bar of the river Neckar next to Ilvesheim. Apart from the main goal of experiencing ‘real life scanning’, the produced data now is used in various analyses: Based on two other datasets from 2011 and 2012***,…

OSM Residential areas get their scales determined
OSM data have no compilation scale information, so we (Chris Kempf, Pascal Neis, Max Rylov and Andreas Reimer) found an efficient way to calculate scale equivalencies for residential areas. While the paper with the description of our linear-time method is under review, please do check out the visualized results! http://openmapsurfer.uni-hd.de/scale-determinator.html Note: the tile server for…

High Cartographic Quality Label Placement on OSM-based Map
In January 2012 we launched OpenMapSurfer – a web map service with a set of custom layers that are based on geo-data of OpenStreetMap project. The main idea was to present OSM data in a different way by placing emphasis on the cartographic representation of data, namely to enhance the quality of the cartographic lettering…
