short announcement: ESRI MOOC – the outline

As we already informed here about the new ESRI MOOC (Massive Open Online Course) we also stated, that it is a pitty that there is no schedule available. Due to this there might be a mismatch between people’s expectations and the content of the MOOC. We also got the information that this MOOC is not for the GIS beginners.

short announcement: ESRI MOOC scheduled

The rumors in the geo-bloggosphere gone crazy last weeks as ESRI announced an own-hosted MOOC (Massive Open Online Course): Tweets über “ESRI Mooc” They already featured this one here at PennState University hosted at Coursera as they provided access to their ArcGIS Online plattform for all participants. Now it seems like they would like to take things seriously. Today they now announced the dates for this new MOOC. It will start on Wednesday the 3rd of September and it will last for about 6 weeks. They also created a Twitter account for this but this is more or less interesting ATM…

Unfortunately not much is know regarding this course: Hands-on exercises, short video lectures, quizzes, case studies and discussion 6 weeks, 2-3 hours of study per week Certificate of completion and prizes But one thing is known: You’ll get free access to the full analytical capabilities of ArcGIS Online, Esri’s cloud-based GIS platform.

The Spiegel Magazine and their “maps”

Today I stumbled upon a “map” on Spiegel Online ( an import news page in Germany ) which shows the spied countries of the NSA. As we already know leaflet quite good and also tried other mapping possibilities I was interested in what they are using for this map which is more informative than this useless map. So looking on the source code: It’s a library called jvectormap.

Online GeoJSON Editor

The web is built upon a small set of languages that are present everywhere. Besides HTML, Javascript is the most common technology around here.  So it is not a surprise that web cartography adapts this technology and uses the native javascript object type to store its vector data. The specification is called GeoJSON (for Javascript Object Notation) and extends the JSON model with geometry fields. But if you ever needed to write some lines of Javascript, you’ll know that it’s brackets can drive you crazy. So why would someone want to write table-like structures in such a quirky format? The…

cartoDB and Leaflet: creating the table or part one

We have already introduced cartoDB which is a platform for storing, administering and visualizing spatial data. One straight feature of cartoDB is the usage of GeoJSON for exporting their tables. In this tutorial I’ll document a working example on consuming this layer with leaflet. But first we will start with the easy part of creating the table in cartoDB.
