Supporting humanitarian logistics with OSM in a more sustainable way: New Disaster OpenRouteService for Africa, South America and Indonesia

Recently HeiGIT @ GIScience Heidelberg released a dedicated stable disaster versionof OpenRouteService (ORS) to support humanitarian logistics within specific regions of catastrophes with data from OSM in a more sustainable way. Since his start in 2008 OpenRouteServivce had been spontaneously applied for specific real world disaster cases already numerous times, for instance during the earthquakes in Haiti 2008 and 2010, in Nepal2015, and in Equador 2016. Yet this always involved manual effort to set the system up for the specific disaster which costed time and manpower. For this reason this was only manageable for specific larger disasters. In order to provide this…

GPX overview: An R function to create an overview of your .gpx files (using leaflet and RgoogleMaps)

Why GPX? For what? It's convenient to record tracks of your hiking/field trips with the GPS of your smartphone, tablet or just GPS as .gpx files. You can use them to georeference your pictures (for example with the great georefencer of Digikam) or use them for any kind of mapping purpose. I'm mainly using Maverick (and sometimes the Offline Logger ) to do that, Maverick creates files named with the form "2015-08-26 @ 11-31-59.gpx", therefore I'm quickly collecting a large amount of such files.

Map a whole city with OpenStreetMap

One day last month, I came back to OpenStreetMap, to see how the city of Legnano (city of 60k people – near Milan – Italy) was mapped. I knew I did not find much, but hoped it would have been mapped to a large extent. I immediately created an atlas with the online tool mapOSMatic and the result can be found here: Download PDF Atlas of Legnano (as it was) or go to the repository mapOSMatic I always talk about OpenStreetMap on my blog and I invite and teach all kinds of mapping. When I realized the state it was in my city,…

Happy B-Day QGIS2leaf

When I started to work on QGIS2leaf about one year ago it was a nice idea and my first real dive into Python programming and using the possibilities of pyqgis. So what is the current state and where are we going? Please, come and take a look: Happy Birthday QGIS2leaf!

Geocoding Addresses in ArcGIS: the other approach

Today I stumbled upon a post from the German ESRI office and their blog gisIQ and a little tutorial (English translation) on how to geocode addresses in the ArcGIS platform. I was asking, whether there is a possibility to use other geocoders as well and so I tried to build my own solution without credits and with the possibility to choose a geocoder. Fortunately the Python world offers some nice little scripts. So let’s use geopy!

How to use OpenStreetMap, guides for beginners and advanced users on LearnOSM.org

OpenStreetmap is the fastest growing community mapping project of all times. Beside the “normal” map result, what you can use for your daily navigation through cities and countries like Google Maps, OpenStreetMap allows you to get the geodata and use it for your own ideas and projects (with some licence regulations). For many peoples the difficult part is not getting the data but the usage and adoption. Therefore the Humanitarian OpenStreetMap Team created LearnOSM.org.

Exploring OSM Israel/Palestine

In this post I’ll show how to explore (or data mine) Open Street Map data and use features off-line that normally can be hard to get. Many use http://download.geofabrik.de to download zipped shapefiles to be used directly in GIS systems, but are surprised when it does not contain as much data as the same area in Open Street Map on-line. You can still use geofabrik.de but download the *.osm.bz2 files instead. They include raw data from OSM that needs to be processed in order to be used in QGIS or other GIS applications. In QGIS there’s a tool in the…

open navigation overview: 4 OSM routing services

Routing is one of the main tasks when using Google Maps and co. Some systems are directly inserted into cars, some others should show us practical routes to the next supermarket or train station. Often routing services are associated with big commercial and proprietary providers like Google, TomTom, Nokia and other ones. In the mean time also routing services powered by the OSM (Open Street Map) community could provide proper routing to get you to your desired destination.

Using OpenStreetMap on your GARMIN

Since most people working with digital-data they are always interested in obtaining their own data using a Global Positioning System (GPS). Therefore I’ll give a short introduction for all of you, using a GARMIN device and like to have a free background map on the screens. There’ll be also the possibility to make routings to certain addresses or Points of Interest. Although the OpenStreetMap Wiki gives some explanations and tipps on bringing OSM to your device, there are some easier ways to do so. But first we have to clarify the question if your device can handle with OpenStreetMap-data: The following devices…
