Photogrammetric Engineering & Remote Sensing
is the official journal of the
American Society for Photogrammetry and Remote Sensing. It is devoted to the
exchange of ideas and information about the applications of photogrammetry,
remote sensing, and geographic information systems. The technical activities of
the Society are conducted through the following Technical Divisions: Geographic
Information Systems, Photogrammetric Applications, Lidar, Primary Data
Acquisition, Professional Practice, and Remote Sensing Applications. Additional
information on the functioning of the Technical Divisions and the Society can
be found in the Yearbook issue of
PE&RS
.

The cover is a 2010 Landsat Thematic Mapper image subset for a portion of Mala-
wi from a national land use and land cover change mapping activity by the United
Nations Food and Agricultural Organization for climate change and carbon track-
ing under the Intergovernmental Panel for Climate Change guidelines. The specific
process used an object based image analysis approach to divide the country into
about 230,000 segments which were then each labeled by Malawian nationals. The
Malawi mapping activity is an interesting combination of machine processing, seg-
mentation, visual interpretation, and the assignment of class types. This example is
from the Highlight Article in this issue by Haack and Ryerson on ‘Training for Remote
Sensing Image Interpretation’. The authors argue that visual interpretation is a very
common and often necessary part of information extraction from remote sensing
data, even when machine methods are used. This is especially so for operational
projects. They conclude that the remote sensing community does not always suffi-
ciently provide visual interpretation capabilities to the work force.
