Global warming may have fueled Somali drought
Global warming may have contributed to low rain levels in Somalia in 2011 where tens of thousands died in a famine, research by British climate scientists suggests. Scientists with Britain's weather
service studied weather patterns in East Africa in 2010 and 2011 and
found that yearly precipitation known as the short rains failed in late
2010 because of the natural effects of the weather pattern La Nina.
Europe, Russia agree tie-up on missions to Mars
The European Space Agency (ESA) said it signed a deal on Thursday with its Russian counterpart to launch two unmanned missions to Mars, a quest that was rocked by a US pullout last year. Called ExoMars, the scheme entails sending an orbital probe to the Red Planet in January 2016 to look for atmospheric traces of methane gas, a pointer to the existence of microbial life.

NIMET’s 2013 seasonal rainfall prediction
Last
weekend, our own meteorologists, the Nigerian Meteorological Agency, briefed
Nigerians about what to expect from the weather this year. The Director-General
of NIMET, Dr Anthony Anuforom, said that the rainfall pattern in most parts of
Nigeria was likely to be similar to that of 2012, however some areas in
North-Western parts of the country, which also fall within the catchment area
of River Niger, are predicted to have a total rainfall that may exceed that of
2012. These are Sokoto, Kebbi, Niger, Kwara states and environs. He advised
relevant authorities to use the NIMET’s updates issued regularly to control
possible adverse impacts, while pointing out that the forecast was not
automatic as the predictions could change due to climate change. In his words,
‘‘The conditions that determine rainfall pattern over Nigeria have become more
variable due to the effects of climate change and global warming.’’

learn how to use Google Map Maker to improve your Google Map Part 1
Sometime in April 2011 Google opened up the U.S. map for editing in its Map Maker application, allowing web
developers and any user, for that matter, to add places, edit places, add
roads, and review edits made by others on the Google Map.
Map Maker gives you the
capability to edit Google Maps directly, giving you access to correct errors
you may find, add missing points or places of interest, roads, monuments,
business locations.
Google Map Maker allows you
to add and update geographic information for millions of users to see in both
Google Maps and Google Earth. Once your edits are made and approved you will
provide the world a more accurate view of the locations and points of interest
that are under your appraisal.

Rigours of the Surveying Profession
Rigours of the Surveying Profession
The fact that the profession is associated with several hours of
fieldwork under the intense African heat is enough reason to discourage
the new comers. This is coupled with the fact that the remunerations are
not commensurate to the amount of time and energy put into each survey
work. The other issue is the high cost of purchase of surveying and
geoinformatics equipments. It is difficult for both the professionals
and institutions afford even on a rental basis. This is coupled with the
fact that the models of surveying equipment change very frequently. In a
continent with so much poverty, it will be difficult to cope with the
cost of purchasing new equipment almost every two years.
The other
is the know-how on the application of the relevant software. The other
issue to deal with is the inconsistent supply of electricity to power
the computers for the processing of the field data. In the case of
manual equipment, manual computations and final presentations becomes an
inevitable puzzle. The combination of the above act negatively on the
survey products in terms of the delivery time and values to be added.

GPS Tip - Position Averaging
Today's GPS tip is using position averaging.
Most mobile GIS software defaults to using one single GPS
position to define the XY of a point feature. That's quick but it
may not be very accurate.
Say that the accuracy of your GPS unit is 3 meters. You can imagine
an imaginary 'accuracy circle' with a radius of 3 meters extending
out from your GPS position.
When you start logging GPS data, the positions come in at whatever
frequency you've specified - maybe one position a second.
The majority of those positions will fall within the imaginary
accuracy circle - some of them closer to your actual location,
others farther out along the perimeter of the circle. Some will
even fall outside of the circle entirely.
If only one GPS position is used to define the feature's coordinate,
it may dead-on at the actual XY, but it might just as easily be
outside of the circle - a difference of 3 meters in this example.
Position averaging allows you to collect several GPS positions
instead of just one. Most will be in the circle, some will not -
but all get averaged together.
That averaged XY becomes the final coordinate of the point feature
and it's a very simple way to improve the accuracy of point data.
Happy Mapping!
