OSM printed: Open Street Map on paper in Chiang Mai

Saturday, April 16th, 2016

For the first time, a printed version of Open Street Maps is now available in Chiang Mai. The map is a cycling map, it highlights roads that are especially suitable for cycling and proposes small routes (based on the class:bicycle key).

The map is printed on A2 (420x594mm) and, with a scale of 1:25,000, covers a good area of around 9 x 13 km around Chiang Mai City.

Land Observatory online

Land Observatory

A global online platform on large scale investments into land was released recently on Any user logged on to the system can provide spatial and context information on land deals. The idea behind is to complement governmental information on land deals with crowd-sourced data that comes from the users and by that strongly improving the data availability- and quality on land deals. is currently being developed and coordinated by the Center for Development and Environment (CDE), University of Bern and the International Land Coalition (ILC).

Socio-Economic geodata of the Lao PDR online

Saturday, June 25th, 2011

Socio-Economic geodata of the Lao PDR is now for the first time online available through the DECIDE info platform. The user can access the data either through map-viewing tools (MapViewer), or directly access the database with an online-gis application (DECIDE GIS).

Why Satellite-Imagery?

Saturday, March 5th, 2011

Satellites everyone knows. From hearsay. But what do these devices actually do, constantly circling the Earth 24 hours a day? In most cases, they are directed towards the earth, in rare cases, they “look” in the other direction, into empty space. Satellites, which are directed to the earth may have many different functions. One important group are the so-called environmental satellites, whose purpose is the monitoring of the atmosphere and the earth’s surface.

At the time of Gauss, you went out into the countryside to produce topographic maps. These  are still an important foundation for today’s surveying. However, even such detail-made maps have the property to become obsolete very quickly. Who has not held a newly bought map in his hands and noted with indignation: “The new ring road is not even on it!”.

Our Earth’s surface is constantly changing. And today even more than before. Man-made movements on the earth’s surface that currently take place, probably have never happened before. It is known that these changes have consequences that could be of explosive significance for mankind (see IPCC 2007). This is just one of several reasons why it is increasingly important to understand what is happening right now with our earth. And here, images from environmental satellites play a central role: permanently new pictures of a changing Earth’s surface.

Geo-statistics and ivory trade

Thursday, December 2nd, 2010

What do Geographers and Ivory have in common? What is a geodetic doing with an elephant-tooth? An item gains geographical significance at the moment, when its location becomes its distinguishing criterion. “Location” means in the geographical sense a coordinate, thus a mathematically definable point somewhere on our earth. Does ivory have a coordinate? And: why and for whom could the “location” of ivory become of interest?

Linearity is old news

Monday, November 8th, 2010

The increasing integration of environmental issues into economic decision-making requires improved methods for the effective capture and visualization of complex relationships. Geographic Information Systems (GIS) offer the possibility to bring confusing decision-making processes into an organized network. This “modern cartography” can serve as a basis for both the operative business as well as for long-term strategies.
