You're right, such a high resolution for all over Europe is unrealistic.
I should rather build a smaller grid for the 20m*20m cells and make an other
coarser grid for the whole Europe.
But, anyway, how can I create a spatial grid from scratch, by defining CRS,
resolution and extent of my grid ?
the maptools library in R can take care of this easily. Look for the
sunriset function. You can get hours of daylight based on times of
sunrise and sunset, and adjust according to whatever type of twilight
definition you wish (i.e. civil vs. astronomical)
hope that helps

I am using R to write a text forecast for particulate matter
concentrations. Given a date, latitude, and longitude I would like to
figure out the local daylight hours. Does anyone know of a resource
that can make this calculation? I wanted to see if there was an
existing resource/solution before di

Hi,
My question is very trivial. I want to create a "blank" grid that contains
regular cells from 20meter*20meter in a WGS84 CRS, covering Europe.
My purpose is to used this grid as a "base layer" to then add some
additional layers (with different resolution and extent) and make some
spatial analys
Hello,
I am running a hybrid model (following Baddeleyet al 2013). I am using the
ppm function, the tendency is being represented by a set of environmental
variables ("im"- format) and the incidence is being represented by a
hybrid model (StraussHard and AreaInter). It seems that everything is

I'm extracting the data to fit a Sen's slope. To accomplish this, a
dataframe is required. A dataframe will be useful to do other kinds of
analysis to see effects of daily rainfall on NDVI. Ultimately all the
results will be converted to rasters. Hope this is useful. Thanks for

Dear bloggers,
I am working with spatial polygons to see how variables are spatially
correlated and how such correlation changes in time in a specific country.
I want to look a bit more into detail at Moran’sI and how the morphology
(surface and/or population) of the areas I consider can impact
Hello,
i think you can do that with Bio7 (OpenSource):
http://bio7.org
It integrates a R GUI
see: http://bio7.org/documentation/Main.html#toc-Section-4.6
and ImageJ GUI
see: http://bio7.org/documentation/Main.html#toc-Section-4.3
in one platform.
