Map making

What's the purpose of my work making maps?

Maps produced are used to demonstrate a range of information and have been
included in local government reports, the most recent being about
watersheds. Firstly, accurate information about the location of communities
and roads is gathered using GPS, and then notes are taken regarding the
different uses of soil as well as areas of erosion. This combined with other
information is then compiled into a map, which enables the identification of
areas most at risk from further erosion and degradation of the soil. They
can then be used further to suggest where future work is needed in order to
protect and conserve an area. Other maps have demonstrated where FH is at
work and in what capacity, as well as areas where future projects are
planned e.g. environmental education, livestock and agriculture training and
plans for providing drinking water and irrigation projects. The map pictured
below depicts the elevation of an area where green is low and red is high,
which is much easier to understand than many contour lines.
