Hi All,
=
I have an interesting problem to solve, I hope someone could help me.
=
We are working on flood early warning in Somalia and we have the followin=
g situation.
=
We have an existing network of manual rain gauges that we receive on a mo=
nthly basis with daily readings taken manually by a person in the field. Th=
ese however can be unreliable.
=
We have an option to install automatic rain gauges that would give us an =
accurate measurement of rainfall per day. We would like to use geo-statisti=
cs to then give a prediction and error surface and then use these surfaces =
to evaluate how accurate and reliable our existing manual network is.
=
Is there a way to calculate the optimal network (number and location) for=
the automatic stations so that we get a reliable prediction surface which =
we can then use to evaluate our manual network?
=
I am the most familiar with the ArcGIS GeoStatistical Analyst.
=
Thanks and regards
Craig
