[GIS] How to reproject all the vector files in a folder to a particular projection using ogr2ogr

ogr2ogrqgisvector

We have a folder with all sorts of vector files like tab,shp,dxf. Many of the files are in different projection. I would like to convert all the files to EPSG: 4326 and eventually the non-shapefiles to shapefiles.

I've used the following command

For %%f in ("*.shp",".tab",".dxf") do ogr2ogr -t_SRS EPSG:4326 "ESRI Shapefile" "%~dpnf.shp" "%%f"

It say's.."Failure COuldn't fetch requested layer".

And how to save the output files in a separate folder, not in the same folder itself

Edit:

I've attached the image of the error

For doing that is required a script; not a command. As I don't know which operative system you have, I am going to use a bash script in my Linux system (in Windows the equivalent is a bat file) and by using only shapefiles.

#!/bin/bash
for i in *.shp
do
ogr2ogr -t_srs EPSG:4326 out_data/$i $i
done

The above script (named as convert and running with ./convert) worked well and it projected all the shapefiles in the current directory to ESPG:4326 and it saved them with the same name in the out_data directory (out_data must be created in the directory where is running the script).

The following image is the working directory with diferents shapefiles and raster (included the script and out_data):

Directory out_data after running the script (the shapefiles were loaded to QGIS with the fly projection activated for verification purpose). It only contain shapefiles with the desired projection.

Editing Note:

I didn't know the bat sintaxis but I found it. It's precisely in one line command. The correct sintaxis is:

FOR %%i IN (*.shp) DO ogr2ogr -t_srs EPSG:4326 "out_data/%%i" "%%i%"

The above bat file (named as convert.bat and running with convert) worked well and it projected all the shapefiles in the current directory to ESPG:4326 and it saved them with the same name in the out_data directory (out_data must be created in the directory where is running the bat file).

Successful execution of the bat file in my XP Windows System:
