Graphics – Before and After

Here just two examples of graphs which were supposed to go into a report (left) and which got a little bit of a face lifting (right)… (data visualization)

SVG and Environmental Statistics

Monday, January 16th, 2012

I’ve build a neat SVG application. It uses data (via a direct database connection) from the UNEP Environmental Data Explorer (ex-GEO Data Portal). Lots of possibilities to play around with the data, for each variable some 40.000 data points.

Keeping Track of Our Changing Environment || Links

Thursday, December 22nd, 2011




New Agriculturist:

“Very much a reference book, Keeping track of our changing environment will prove an invaluable and accessible source of data that underpins a proper understanding and interpretation of numerous issues confronted daily by readers of New Agriculturist, whether specialist advisor, educator or policymaker. Eye-catching and providing much ‘food for thought’, UNEP is to be congratulated for conceiving and commissioning this ‘must have’ publication.”

Friends of Europe

Although the authors of the report have carefully avoided providing any critical evaluation of the statistical data, anyone reading the 111-pages study can hardly conclude that global leaders have done a great job since they received a wake-up call about the world’s sustainability challenges twenty years ago.
All in all, the UNEP study is an impressive work of data collection but it could have done with a little bit less spin and a bit more “hard” evaluation. But then again, maybe this document has a political function and the real meat can be expected in May of next year?

National Round Table on the Environment and the Economy

Graphs of the report used in the PPT of “NRT President and CEO” David McLaughlin

Our World 2.0:

This report is proof that, through restrained use of technical language and intelligent application of design tools and graphs, complex messages can be conveyed to wider audiences. Overall, Keeping Track does a good job of explaining to us where we have come from. Where we are going is now up to all of us.

The environmental changes that have swept the planet over the last twenty years are spotlighted in a new compilation of statistical data by the UN Environment Programme (UNEP), released today in a report entitled “Keeping Track of our Changing Environment: From Rio to Rio+20“.

Bubble Chart on Emissions

Monday, December 20th, 2010

An updated version of the Bubble Charts which I’ve done last year, this time with a linear scale as well, as well as the Human Development Index used instead of the GDP. So, here one can see the HDI on the x-axis, the per capita CO2 emissions on the y-axis, the total emissions by size of the bubble, the total population by size of the font for the country name, and the region (colored circle) a country belongs too. Plus, the regional aggregates have been plotted too. PDFs can be downloaded here.

GIS: Data

Tuesday, February 16th, 2010

Natural Earth is a public domain map dataset available at 1:10m, 1:50m, and 1:110m scales. Featuring tightly integrated vector and raster data, with Natural Earth you can make a variety of visually pleasing, well-crafted maps with cartography or GIS software. Natural Earth Browser here.

Shipping Lines

Monday, January 18th, 2010

Between science and art: Commercial shipping activity can lead to ship strikes of large animals, noise pollution, and a risk of ship groundings or sinkings. Ships from many countries voluntarily participate in collecting meteorological data globally, and therefore also 7 report the location of the ship. We used data collected from 12 months beginning October 2004 (collected as part of the World Meteorological Organization Voluntary Observing Ships Scheme; http://www.vos.noaa.gov/vos_scheme.shtml) as this year had the most ships with vetted protocols and so provides the most representative estimate of global ship locations. The data include unique identifier codes for ships (mobile or a single datum) and stationary buoys and oil platforms (multiple data at a fixed location); we removed all stationary and single point ship data, leaving 1,189,127 mobile ship data points from a total of 3,374 commercial and research vessels, representing roughly 11% of the 30,851 merchant ships >1000 gross tonnage at sea in 2005 (S14). We then connected all mobile ship data to create ship tracks, under the assumption that ships travel in straight lines (a reasonable assumption since ships minimize travel distance in an effort to minimize fuel costs). Finally, we removed any tracks that crossed land (e.g. a single ship that records its location in the Atlantic and the Pacific would have a track connected across North America), buffered the remaining 799,853 line segments to be 1 km wide to account for the width of shipping lanes, summed all buffered line segments to account for overlapping ship tracks, and converted summed ship tracks to raster data. This produced 1 km2 raster cells with values ranging from 0 to 1,158, the maximum number of ship tracks recorded in a single 1 km2 cell.
Because the VOS program is voluntary, much commercial shipping traffic is not captured by these data. Therefore our estimates of the impact of shipping are biased (in an unknown way) to locations and types of ships engaged in the program. In particular, high traffic locations may be strongly underestimated, although the relative impact on these areas versus low-traffic areas appears to be well-captured by the available data (Fig. S2), and areas identified as without shipping may actually have low levels of ship traffic. Furthermore, because ships report their location with varying distance between signals, ship tracks are estimates of the actual shipping route taken.
What happens in the vast stretches of the world’s oceans – both wondrous and worrisome – has too often been out of sight, out of mind. The sea represents the last major scientific frontier on planet earth – a place where expeditions continue to discover not only new species, but even new phyla. The role of these species in the ecosystem, where they sit in the tree of life, and how they respond to environmental changes really do constitute mysteries of the deep. Despite technological advances that now allow people to access, exploit or affect nearly all parts of the ocean, we still understand very little of the ocean’s biodiversity and how it is changing under our influence. The goal of the research presented here is to estimate and visualize, for the first time, the global impact humans are having on the ocean’s ecosystems. Our analysis, published in Science February 15, 2008, shows that over 40% of the world’s oceans are heavily affected by human activities and few if any areas remain untouched.

Visualising the Trend of Environmental Data

Unique way of showing the trends of environmental data, either by countries, or by regions. Really neat! Source here and download PDF national here or regional here.

CO2 Emissions and Wealth
