Lining Up Data in ArcGIS – a guide to map projections is a new book from ESRI Press. It is authored by Margaret M. Maher. Since I don’t have ArcGIS running in my office I couldn’t try out some of the details provided in the book, nevertheless, I did spend some time running through the book and offer the following comments.

One of the issues that many people encounter with GIS data revolves around projections, coordinates and lining up data with already existing spatial information. I’ve made the mistake myself numerous times, excited to get the data into the system, only to open the map window and finding what I just added from Berlin is placed in Oklahoma, Alberta or the middle of the Mediterranean Sea. How did that happen? Because I never lined up the data properly.

This book is very helpful. It explains how to identify geographic coordinate systems as compared to projected coordinate systems. If you are using ArcMap, then this book will show exactly how to determinine projections and set them. It even provides examples for going to ArcGIS Online, downloading imagery and aligning it properly.

Carbon Report Available: Data and Statistics

Wednesday, March 12th, 2008

point carbon logo(From VectorOne) Point Carbon released a report (pdf press release) in Copenhagen, Denmark yesterday at the Carbon Market Insights Conference 2008. The report explores in-depth the following key findings (lots of numbers here):

Global carbon markets worth USD $60 billion (€40 billion) in 2007, up by 80 percent from 2006. The total traded volume increased by 64 percent from 1.6 Gt (1.6 billion tons) in 2006 to 2.7 Gt in 2007.

“Point Carbon predicts that the global carbon market will see 4.2 billion tons
carbon emissions (CO2e) transacted during 2008, up 56 percent from 2007.
At today’s prices, that would make the market worth USD $92 billion (€63 billion).”

There seems to be a generally bullish sentiment on carbon, not necessarily reflected in current market prices. Survey respondents now on average expect a carbon price of USD $37/ton (€24/ton) in 2010 and USD $ 54/ton (€35/ton) in 2020, which is USD $9 (€6) and USD $15 (€10) higher, respectively, than they expected a year ago. This demonstrates that market participants now realize that the EU ETS will face a considerable shortage and that much of this will have to be met through reductions taking place in Europe.
