GeoMonday 2015.3 – Capturing the world in 3D: beyond OpenStreetMap

OpenAerialMap, OpenDroneMap, OpenUAV – there are plenty of new projects around the idea of leveraging UAVs and digital cameras as a map data source. They are all following OpenStreetMap’s idea of creating a new map data source that is open. The talk will give an overview of the OpenAerialMap initiative and how to use the OpenDroneMap (ODM) software package to create 3D models and ortho-images. Some thoughts about the meaning and future of ubiquitous UAV technology for data capturing and surveying will aMartin_Scholl_1 smalllso be presented.

Martin Scholl is a software engineer and 3 times company founder. His current focus is 3D digital perception and digitalization with applications in robots, autonomous systems, and art marketing.

GeoMonday 2015.1 – Does this place have stairs at the entry?

Holger and Raul, who is using a wheelchair, had to ask this question a lot when they wanted to go somewhere. So they build, a map to find wheelchair accessible places. Since it’s launch 5 years ago over 500.000 places have been tagged by volunteers all over the world, making it the biggest database of it’s kind. is online in 22 languages and also available as iOS and Android apps. Being an OpenStreetMap project all it’s data is available under an open license. is run by SOZIALHELDEN, a non-profit based in Berlin which launched many follow-up project since then. One is the service where visitors can see which elevators are currently out of service in the Berlin public transportation system.

Holger is the co-founder of and will tell us about the opportunities and challenges they saw when building these projects on top of open data, what things they tried and failed and how he sees projects like these in the long run.

About Holger Dieterich
When Holger is not at SOZIALHELDEN, he is active in the Berlin Startup scene as coach and mentor for entrepreneurs, curator of the StartupDigest and running events like the Lean Startup Meetup and Usabilityfix. He has a degree from the University of the Arts Berlin and worked as product manager before.

GeoMonday 2015.1 – Barrier-Free Routing for Increased Mobility and Accessibility Using OSM

mdv2As part of the SIMBA (Safe and Mobile with Assistance Systems) research project, Mentz Datenverarbeitung (mdv) has integrated data from the OpenStreetMap (OSM) project into its trip planner system, enhancing the routing algorithm to increase mobility and accessibility using the available attributes in OSM.


The project goals are to ensure autonomy of the elderly and disabled and to provide safe and comfortable trips that account for their specific mobility limitations.

One of the new improvements is the consideration of specific link types and attributes, which are imported from the OSM source data and integrated into the routing network graph.

mdv1Marc Ullrich has studied civil engineering at the TU Munich and works as a Senior Software Engineer at mdv (Mentz Datenverarbeitung GmbH). He is member of the EFA journey planner developer team and works on national and international projects. Find his LinkedIn profile here:

GeoMonday the 2nd – Talk 1: Buildings in space, sun in time

Jan MarschAs a freelance software engineer Jan Marsch is driving enterprise web applications for a long time. A few years ago he got addicted with maps and is engaged with OSM Buildings – an open source JavaScript library for visualizing 3d building geometry.

In his talk, basing on OSM Buildings, he will add another dimension to OpenStreetMaps data just by algorithms. The discussion covers some details about the concepts, code and pitfalls.
