结合QGIS在MAC终端中使用GDAL和ogr实用程序

Question

I am pretty new to the open-source GIS software. I am trying to clip and project data layers using GDAL and ogr in my MAC terminal. I can get the data to clip when I am just clipping but when I try and combine the two (clip and project), I am getting a syntax error. The syntax I have was written for Command Line and I'm thinking I may need to tweak it for terminal. Any help would be greatly appreciated! If someone is willing to help, I will try and provide more information if necessary.

Here is my line of code:

$for %X in (*.shp) do ogr2ogr -skipfailures -clipsrc
~/Desktop/PhiladelphiaBaseLayers/clipFeature/city_limits.shp
~/Desktop/PhiladelphiaBaseLayers/clipped/%X
~/Desktop/PhiladelphiaBaseLayers/%X

When I run the code, I receive this error message:

-bash: syntax error near unexpected token `('

Switcher from windows to mac? ;)

If I understand right your intent is run the ogr2ogr with 3 file arguments

try the next

for shpfile in *.shp
do
    echo ogr2ogr -skipfailures -clipsrc \
       ~/Desktop/PhiladelphiaBaseLayers/clipFeature/city_limits.shp \
       ~/Desktop/PhiladelphiaBaseLayers/clipped/"$shpfile" \
       ~/Desktop/PhiladelphiaBaseLayers/"$shpfile"
done

when you satisfied, remove the echo

This is what ultimately worked for me. Take out the quotations around the variable call. All one line.

for f in *.shp; do ogr2ogr -skipfailures -clipsrc ~/documents/PhiladelphiaBaseLayers/clipFeature/city_limits.shp ~/documents/PhiladelphiaBaseLayers/clipped/$f ~/documents/PhiladelphiaBaseLayers/$f; done
