Sometimes shapefile becomes bulky to carry from one place to another. As it contains various files as .shp, .prj, .shx, .dbf etc. On the other side CSV contains every detail in one file. So CSV can be considered as a good option when you don’t need to render data on map as polygon or polyline or point. There are various options to create CSV from a shapefile either offline or online.
CSV is comma separated value file which is one of the alternative method for storing spatial data in spreadsheet format. You can also upload the Excel file and convert it into spatial data via QGIS tool. There are also other online tools available which can directly convert the Shapefile to CSV. We will show you how easy and useful is IGISMAP for the conversion process. Following are the methods to convert Shapefile to CSV using IGISMAP Converter tool.

Shapefile to CSV conversion – OFF-Line (command line) Tool
For using off-line command in your system you need to install ogr2ogr. There is very simple command to convert shapefile to csv file if you dont want to install a bulky GIS tool like QGIS or ArcGIS.
I am giving a way to install GDAL on ubuntu, while the process is almost similar to install the GDAL tool in Windows, Mac or other Linux system.
For installing GDAL for Ubuntu please follow the given commands.
After installing you can check the availability of ogr2ogr by typing ogr2ogr on terminal.
After that you can follow the command to convert the shapefile to csv (comma separated value format file)
–> ogr2ogr -f CSV output_file_name.csv input_shp_name.shp -lco GEOMETRY=AS_WKT
The same work can be done in code-igniter or using PHP. For that you need to execute this command in shell_exec() method, which takes the command in string format and returns the output in string.
–> $shpToCSV=”ogr2ogr -f CSV $out.csv $shp.shp -lco GEOMETRY=AS_WKT”;
These statements are written in PHP. $ signifies the variable. Here input and output is taken from user and command is written in double quotes to convert in string. Then it is given to shell_exec() method.
Shapefile to CSV conversion – With QGIS Open source Software
