qualitative change assessment of environmental
The GTOS secretariat
has the pleasure to announce the release of a new service providing
a qualitative change assessment of environmental variables measured.
would be made, on an appropriate basis, by each site’s manager.
For example, the variable “water potability” could be
marked with a positive trend if the measurement shows that it the
water is becoming more potable, negative if it is becoming less
potable and neutral if there is no change.
Less than half
of the 120 variables in TEMS
are concerned by that tool since most of them can’t be considered
as an indicator. An improvement of the ecosystem’s condition
should always be marked as a positive change. The latest assessment
will be then displayed, as an arrow, beside the list of the variables
measured by the site. Another small icon besides it will also provide
a quick access to the entire time series as a graph.
Please see example
map interface of TEMS will also represent for one variable all the
assessments made by the sites measuring it. A positive change could
be represented by a green dot, a negative one by a red dot and a
stable trend by a blue dot.
Please see the
for “Forest cover change”.
that this service has been recently released and will start being
populated by the site managers.
We would most
welcome any feedback concerning this new service at firstname.lastname@example.org
