Import OSM Data Into A PostGIS Database (The Easy Way)

I often find myself in a situation where I want to work with large areas and datasets of OpenStreetMap data. No matter if you want to use them in a QGIS map or create custom map tiles in Tilemill, with the Overpass API you quickly run into performance issues. Imposm is a great tool to overcome that situation, so you can load OSM extracts (worldfiles in pbf format) with a custom data mapping into a PostGIS enabled PostgreSQL database. The downside: It is hard to set up if you are not a database and system admin guru. This is where…

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,…

Routing in QGIS… with OSM

Routing with Google is quite cool as the database/network is probably the best currently available. But the terms of services limit the possible usage. So what about OpenStreetMap? By figuring out how to use OSM for routing I found it much easier to get routes into QGIS with OSM compared to the Google way. Check it out….

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.

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…

uMap – easy open source webmap creation based on OSM, Leaflet and Django

Creating maps is the most appropriate way to present spatial data. In the last years several methods appeared to generate such webmaps. Based on a tile-layer, wich contains all basic map informations such cities, motorways, natural elements etc, even inexperienced computer users can drop their informations with ease. Nevertheless there are some methods and services, wich are easier than others, even if they have less options in map configuration. uMap can be classified as such a smart and easy way to get your spatial informations on a reasonable webmap, which can easily embeded to your personal homepage and so on.…

Kurznotiz: Hilfe zu OpenStreetMap

OpenStreetMap ist ein wunderbares Projekt, dass ähnlich dem Wikipedia-Prinzip arbeitet und eine freie Weltkarte erstellen will. Damit ist das Projekt auch schon ganz gut fortgeschritten. Wer sich über den derzeitigen Stand informieren will, wird hier fündig. Inzwischen hat sich OpenStreetMap auch zu einer unersetzlichen Quelle entwickelt, wenn man günstig Kartographie erstellen möchte, sowohl für Print als auch fürs Web.
