## Session of yesterday

* Github page is forked to the GitHub Geo-scriptin @ WUR group

    * Presentation is available here: http://divisionblue.github.io/wur-python/
    * http://geojson.org/geojson-spec.html

## Tuning the terminal

* More info: http://www.drbunsen.org/the-text-triumvirate/

* Look for the following plugins to tune your `terminal`:

    *  TMUX: http://tmux.sourceforge.net/
    *  [Powerline](http://computers.tutsplus.com/tutorials/getting-spiffy-with-powerline--cms-20740)

## Shell scripting

```{r, engine='bash', eval=FALSE}
#!/bin/bash
cd ../data
fnin="ndvi.tif"
fnout="ndvi_latlong_60.tif"
fntemp="temp.tif"
fnpng="ndvilatlong.png"
echo "resample the inputfile: $fnin"
gdalwarp -tr 60 60 -r cubic $fnin $fntemp
echo "reproject to lat/long: $fnout"
gdalwarp -t_srs EPSG:4326 $fntemp $fnout
rm $fntemp
gdal_translate -of png $fnout $fnpng
echo "The output file: $fnout"
```

A nice and complete example (works on linux):
