SHP to GML – Convert Shapefile to Geography Markup Language

Shape file shp to GML conversion is required when you carry data from one place to another. Shapefiles are heavy as compared with GML (Geography Markup Language). On the other hand we can say that GML makes you able to do many of the same things that you would do with heavyweight desktop GIS files.

For a more in-depth guide on this topic, be sure to check out our accompanying video tutorial, where we walk you through each step visually and provide practical demonstrations.

Convert SHP to KML using MapOG Tool Converter

GML (Geography Markup Language) is about describing kinds of geographic objects. This is XML based language that contain two part- the schema that describes the document and the instance document that contains the actual data. GML schema allows users and developers to describe generic geographic data sets that contain points, lines and polygons. Using this schema user can differentiate between geometry primitives.

GMl format composed of geometry property and attribute detail in feature member tag. Here geometry defines which primitive is available in data. Whether it is point, line or polygon. These can be multilinestring or multipolygon. The given line of GMl defines the lineString, contains attributes as MED_DESCRI, RTT_DESCRI, F_CODE_DES, ISO and ISO_country in ogr tag. The srsName(Spatial reference system name) is given is file for each geometry as EPSG number.

Convert shapefile Shp to GML (Geography Markup Language) using Ogr2Ogr –

For converting shapefile in GML format you need to have ogr2ogr utility in your system. If this is not available you can follow the given procedure.

Convert Shapefile shp to GML - Geography Markup Language
Convert Shapefile shp to GML – Geography Markup Language

After installing, you can check the availability of ogr2ogr in terminal by typing ogr2ogr, then you will be able to see the following result.

Convert- Shape file to GML

Command Line conversion – shp to gml-

Now, to convert Shapefile to GML you need to execute the following command-

Convert- Shape file to GML

In this command -f is the output file format i.e. GML then specify the output file name with .gml extension and after that input shapefile name with .shp extension.
Note- while executing this command you must check for .shx file, which contains the positional index for geometry objects.

Code- Convert shp to GML

If you want the conversion using programing or don’t want to use terminal then this can also be done using PHP. You can create a function that defined this command as string and can give this string in shell_exec() method to execute. Shell_exec() actually execute the command and returns output as string.

public function shptogml($shpfilepath,$output){
$query=”ogr2ogr -f GML $output.gml $shpfilepath”;
print_r($query);
shell_exec($query);
}

The GML output file will be something like this-

Convert Shapefile shp to GML - Geography Markup Language

Change coordinate system of GML file from shp-

Many of times, we need the output file in other coordinate system. For this we can use options of ogr2ogr utility. It has

-t_srs srs_def:

Reproject/transform to this SRS on output

-s_srs srs_def:

Override source SRS

So using these option, we can get the data in required coordinate system. So for this you can write the query as-

–> ogr2ogr -f GML -t_srs EPSG:32643 (new EPSG) -s_srs EPSG:4326 (old EPSG) newGmlFile.gml InputFile.shp

SHP to GPX / GPS – Convert Shapefile to Global Positioning System

Shapefile shp can be converted into GPS ( Global Positioning System) using ogr2ogr utility. The GPS data is best option when routes and tracks are required in XML format. Here we will check how to convert shapefile shp to GPX / GPS.

Convert Shp to GPX – Using IGIS Map Tool

Go to MapOG Conversion Tool . Login with registered id and password or if you are new then register with valid email id. Then tap on Switch To button select conversion in the drop down list.

Upload your file from system or drive or from drop box. After uploading the file choose the output format. And in the last click on Convert File button. You will be directed to the map where converted file is published.

Download the converted SHP to GPX file from the download icon. For detailed conversion watch the video provided below.

Details for GPX/GPS (GPS Exchange Format) and Shapefile Format Before Converting Shapefile to GPX GPS data-

GPX (GPS Exchange Format) is a light-weight XML data format for the interchange of GPS data (waypoints, routes, and tracks) between applications and Web services on the Internet. Shapefile is collection of geometry with attributes mainly comprised of three files .shp for which stores geometry, .shx which stores index and .dbf which stores data of respective attributes.

The example is given below for linestring feature of gpx version. Here metadata contains the bounding box with min (lat,long) and max (lat, long). The tag trk defines the tracks, which contains extension tag, trkseg tag and trkpt tag. Here extension tag contains all the attributes in ogr tag with values. Trkseg tag is the track segment, which is composed of track points with latitude longitude.

Convert Shapefile to TopoJSON

ESRI shapefile are the binary vector data storage format for storing the location, shape, and attributes of geographic features. It is stored as a set of related files and contains one feature class. Whereas TopoJSON (topological geospatial data) is an extension of GeoJSON that encodes topology. The necessity of conversion is to reduce the size of data. While using Shapefile, you have to take care of all its mandatory files such as .shp, .shx, .dbf, .prj etc. Whereas GeoJSON and TopoJSON formats are single file formats.

There are many online and desktop application based solutions to do this conversion. But the method everyone looking forward is an easy way to convert a file to a preferred format. In this article we will see how easy is IGISMAP for the conversion process. Following are the methods to convert Shapefile to TopoJSON using IGISMAP Converter tool.

Use Online Converter Tool – Shapefile to TopoJSON MapOG

IGISMAP (Now MAPOG) to Convert Shapefile to TopoJSON

Go to MAPOG Converter Tool, after logging in with your registered email and password. If you are a new user, click the Sign Up button in the Login popup and register to IGISMAP by filling the details.

There are three main steps for using GIS Converter:

  • Upload the data
  • Choose the format to which it should be converted
  • Download the converted file.

Step one is to upload your Shapefile which you want to convert. You can upload the file from your system or select from the Recent Files.

Converter Tool - Upload Shapefile
Upload Shapefile

Here we using the Shapefile of India state level boundaries with demographic information. You can find this data in IGISMAP GIS Data Collection –

Step two is to select choose the output format of the converted file, in this case its TopoJSON. You can also set the Coordinate Reference System of your preference. As a default CRS will set to WGS 84 (World) [EPSG:4326]. Click on the Convert File button.

Converter Tool - TopoJSON as Output Format
Select TopoJSON as Output Format

Your Shapefile will then get converted to TopoJSON file after a few seconds and will be published in the map canvas. You can download the TopoJSON file of New York state boundary by clicking the Download Converted File button.

Download and Publish TopoJSON File
Download and Publish TopoJSON File

You can also choose to style the layer or continue with further conversion process by clicking the Convert Another File button.

Converted Files section from the dashboard contains the list of the details of all the conversion done in your account, providing both input and output data available for download their corresponding formats.

IGIS Map Converter Tool provides many benefits other then just conversion of data. This tool provides us to generate this published map in PDF or as image format.

Info GIS Map supports most of the commonly used GIS or AutoCAD files like Shapefile SHP, KML, KMZ, CSV, TopoJSON, GeoJSON, GML, DXF, GeoTIFF, NetCDF, GRIB, HDF5, OSM, PBF, and many more raster and vector files, along with that it support more than 4000 Coordinate Reference System.

Here are other two ways to convert shapefile to topojson

Use Online Converter Tool – Shapefile to TopoJSON MapOG

Offline Method : Convert Shapefile to topojson through GDAL and then through geo2topo tool npm:

To convert shape file to topojson format offline you need to download GDAL and Node.js.  First step is to convert shapefile to geojson data format, which is done by using ogr2ogr command available in GDAL package. After successful installation check ogr2ogr availability by typing ogr2ogr in command prompt or by typing dir that will show all available directories.

convert shapefile to topojson

Now you can convert shapefile to geojson data format by using given command

  • Ogr2ogr –f Geojson file_name.json input.shp

Here –f option is used to shows the file format, which shows output file format is geojson. GDAL takes name of output file prior to input file.

Convert geojson to topojson:

Now to convert geojson data to topojson data format you have to download node.js which is available https://nodejs.org/en/ here. After successful installation you need to check npm availability using command

  • npm –check.
convert shapefile to topojson

If not available use

  • npm install -g npm-check

After this you need to install topojson-server for conversion of data that can be done by using

  • npm install topojson-server command

Now all setup is ready

Use geo2topo command to convert geojson data to topojson data

  • geo2topo –o geo.json topo.json

Here –o option is used to give the output. If command doesn’t run and gives error as no such file or directory. Then specify full path for file for both input and output. The older versions were having topojson as a command to convert geojson data format to topojson data format. Topojson is named as geo2topo command in new version.

Convert Shapefile to TopoJSON – Online Method

Mapshaper is an online tool that converts shape file to topojson data format directly. You only need to drag the shape file to http://mapshaper.org/ site. Then use export option to convert this data into topojson format. In Mapshaper there are many option are available to simplify the geometry, which you can explore.

I hope this article helped you in converting the file from Shapefile to TopoJSON. If you find any problem in performing operation do let me know by commenting below.

Convert GeoJSON to TopoJSON – GIS

Convert GeoJSON to TopoJSON. GeoJSON is an open standard format designed for representing simple geographical features, along with their non-spatial attributes, based on JavaScript Object Notation. The need of conversion is to reduce the size of data, so that rendering of data on browser can be made faster. TopoJSON (topological geospatial data) is an extension of GeoJSON that encodes topology. Here we have explored two methods for conversion of GeoJSON to TopoJSON (i.e. online and offline).

Use Online Converter Tool – Geojson to TopoJSON MapOG

Offline Method to Convert GeoJSON to TopoJSON:

You can directly convert GeoJSON to TopoJSON with the help of topojoson-server node package manager. For using this package you need to first install node js in your system (can be installed in windows, linux based operating system or Mac).

If you have Shapefile or KML file, then you can refere this articles i.e convert kml to shapefile, convert shapefile to GeoJSON and converting shapefile to kml, so that you can generate new GeoJSON file out of other GIS format files.

Convert GeoJSON to TopoJSON – NPM method

NPM (Node Package Manager) is a command-line utility that aids in package installation, version management, and dependency management or can be considered npm as a tool that helps to install another tools like topojson-server.

For this method you need to download node.js which is available https://nodejs.org/en/ here. After successful installation you need to check npm availability using command

  • npm –check.

If not available use

  • npm install -g npm-check

convert geojson to topojson
convert geojson to topojson

After this you need to install topojson-server for conversion of data that can be done by using

  • npm install -g topojson-server

Now all setup is ready

Use geo2topo command to convert geojson data to topojson data

  • geo2topo –o geo.json topo.json

Where geo.json is the geojson file i.e input file and topo.json is the file we are creating with the name topo as topo.json file i.e output file.

Here –o is output. If command doesn’t run and gives error as no such file or directory. Then specify full path for file for both input and output. It is recommended that you run this command from the same directory where geo.json file is stored.

If you don’t have any input files ready or any geojson or shapefile then you can download free GIS data fromat for testing this article.

Online method: Convert GeoJson to TopoJson

This is the simple and fast method. For the conversion you just need to drag the geojson file in http://mapshaper.org/ site. Then use export option to convert this data into topojson format. Map shaper website render and convert the file in the browser itself, but it you might face problem while converting a big geojson file. 

I hope that this methods listed above to convert geojson to topojson would have helped you in achieving result. If you find any problem or know any other method to perform this operation and want to share with us, then do let us know by commenting below, in the box provided.

Different ways to convert Shapefile to GeoJSON – Online or Offline or API

Convert Shapefile to GeoJSON. Shapefile, ESRI made a standard vector file format which is largely adopted in the field of GIS by programmers and geographers . While GeoJSON is also an open standard format designed for Web which largely supported with GIS JavaScript API, other programming API and with GIS (Geographic Information System) software tools too, for easily rendering. GeoJSON is based on JavaScript Object Notation. Here we will explore different methods to convert the files online, or offline or with the help of API which programmers can make use of.

Not only this, but you can classify the Map according to the shapefile dbf attributes and automatically classify and color it. The classified map can be exported as Scalable Vector Graphics i.e svg file.

Disclaimer: The above project is handled by me and my team and the project is in beta phase while you can definetly convert the shapefile to GeoJSON at client side securing your shapefile data. I would welcome your suggestion to improve the tool by commenting below or contacting me.

B.) Map Shapper : 

Map Shapper is the best tool which we should refer first. It is the best online tool which also handles large shapefiles and renders it quickly. Its an open source project and is licensed under MPL 2.0. Just drag the shapefile or zipped shapefile which will render the shapefile on map and can be further exported as geojson file with the option provided in tool itself.

different ways to convert Shapefile to Geojson - Online or Offline or API

With No doubt Map Shaper is much more better than any other tool for now, while the only reason why I placed this tool in second place just because the first tool was my own tool which provides more option for classifying the map, see all attributes in the data table and also exported as svg file.

2.) Offline Method – Convert Shapefile to GeoJSON in QGIS:

You must have installed QGIS  (Quantum GIS) before performing the provided steps. You may also look over other tutorial in QGIS.

1.) Open QGIS Desktop and Select Layer -> Add Layer -> Add Vector Layer or click on Add Vector layer icon appears at the upper left in the application.

3.) Offline Method – Convert Shapefile to GeoJSON with command line ogr2ogr tool:

Firstly you need to install an ogr2ogr tool of GDAL which is a GIS utlitly command line tool so as to convert one file to another. Now if the ogr2ogr is installed globally check by simple tying the ogr2ogr in command line if it is working or not. Or if it residing in some file system you need to navigate to ogr2ogr file and type in the same in command line. Now Just type in the following:

  • “ogr2ogr -f GeoJSON -t_srs crs:84 [name].geojson [name].shp”

To get more option list and format you may see this gdal org link.

This tool will be helpful if you want to convert bulk files from shapefile to geojson. You can refer the .sh script found at github.

4.) Convert Shapefile to GeoJSON -API or library:

Shapefile is a binary file and cannot be viewed directly in notepad or textpad as like with GeoJSON file. So if you want to create your own API, to convert Shapefile to GeoJSON you should first have a knowledge of how to read the binary shapefile. You may refer to some of the articles which I have written some post which would help you to get the basic knowledge to know the format of files and read.

You may further refer to some of the best Shapefile to GeoJSON converter API which is open source project:

https://github.com/wavded/js-shapefile-to-geojson :  This is dedicated library to convert to GeoJSON, created by Marc Harter and Licensed with MIT.

https://github.com/gipong/shp2geojson.js : This library is also MIT Licensed and is inspired by the above wavded library which uploads zipped file of shapefile. The library provided an example to use with leaflet js.

https://github.com/mbloch/mapshaper : Map Shaper as desricbed above is licensed under MPL 2.0 and can be very useful if you want to convert to GeoJSON as well as TopoJSON.

Hope this article helped you. If are facing some problem in converting the shapefile to geojson do comment below with the problem statement. We will definitely look over that. Also you can provide your valuable comment below if you are using any other library or tool to cover the same.
