Last time we had the task to create mountain ranges polygons for the whole world. I prepared a small tutorial referred to that. Maybe you can find something interesting for you. It will show you a model on how to select defined regions, slicing raster, smoothing and also exporting desired features. Enjoy!
Sometimes I have something to tell, but also need to realize that it is not so easy to explain. How many times have you heard of Linux, or maybe Ubuntu? Probably very often, right? I imagine that the comments were (between you and those who spoke, newspaper or friend who is): “Do I need to delete Windows?”, “It is easy, just if you know to program!” or “but there are problems with the printer…” But what makes me proud is when I ask the question, but you use it for work? The Linux world has had a big leap forward…
Perhaps you have already used in your work OpenWebGIS or just have seen it or read about it. Due to this system exists since 2014. But we will describe OpenWebGIS briefly. It is an open source online/offline geographic information system for work in web browser or mobile app. Since its foundation, a great number of users have benefited from using this system functions.
Since 3 years digital-geography.com provides a nice page for your job search in the fields of GIS and Geosciences. As most of our visitors are young professionals, which are not necessarily interested in a job near their home, we started this job page with a webmap from the very beginning. Now we made a big rework of the side.
5 reasons why I blog, and why shall you. About 4 years ago I started blogging and building a website/blog with content about GIS, geodata and programming. As I am an IT consultant for banks and mainly working as a testmanager in a SAP-software surrounding in Switzerland you might ask: “Why the heck do you this?”. Check out my motivation and reasons why I blog and spend time here.
Berlin is the place to be for the geo-industry… Visiting the INTERGEO 2015 in Stuttgart I came to one conclusion: Berlin is the place to be. Forget about Munich, Munster or Bonn. Pack your stuff and head east. Just let me support my opinion a bit with some facts
Last years INTERGEO in Berlin was an interesting experience for a newbie in the world of geodesy like I am. This year I will also attend the INTERGEO in Stuttgart. It will take place from the 15th to the 17th of September. This year’s main points: The spotlight will be on Geospatial 4.0, the digital economy, transformation through digitization, big data, the Internet of Things, digital infrastructures and smart cities.
Typically GIS and geodata nerds are male. Anyhow, 99.9 % of our contacts, freelancer sign ups, comment writers here on the blog are boys. But where are the GIS girls and women? There must be thousands of well educated, very interested hackathon-proven GIS ladies out there. In order to getting in touch with that obviously shy species, I formulated 4 theses about GISgirls. Hopefully many active GIS and geodata girls (and women) will read that and comment in the bottom section. I would be very happy to get your feedback!
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,…
Anita showed some nice examples of tweets in QGIS in 2012. Since then it seemed to be quiet about the twitter-content in QGIS. Yet tweets can be an interesting source of information. Sometimes they can tell you something about the spatiotemporal dimensions regarding a keyword, the digital heartbeat of a defined region and many more. Yet we need to be careful with the data as it is completely biased. But how to get this data stream into QGIS?
The Ordnance Survey is UK’s mapping agency and frequently releases free datasets. Their OpenData policy is quite progressive compared to Germany’s and they’ve recently published some fresh datasets that anyone can use. All you need to do is to register and to acknowledge them. The new datasets are: OS Open Map – Local; OS Open Names; OS Open Rivers; and OS Open Roads. They include data on urban and rural features, an index for all the location names in the UK, a generalised open water network, UK’s connected road network and much more. All this adds up to their existing…
The normal way of getting Landsat data for your GIS projects often was: visit a Landsat data mart like landcover.org, earthexplorer or WIST, search for your area and time and download/order your desired data. Once you’ve done this, you were prepared to add, analyse and publish this data/results with QGIS. Luca Congedo from the blog “From GIS to Remote Sensing” .
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!
