Tag: kml to shp

Convert kml to shp shapefile. Have you extracted and downloaded kml file from Google Earth or Google map and want to render it with your geo library which support shapefile? Do you have KML data given from third party and want to give a proper representation of data over map by converting the same in shapefile? If so, here is an article to convert kml to shp using command line tool ogr2ogr or using php code. While if you use QGIS tool, you can look over kml to shp convert using QGIS or else continue using this article.

Here is the online Tool To Convert KML To SHP Shapefile

KML (Keyhole Markup Language) is very popular GIS format. It is available in text format containing tags such as Placemark, SimpleField, SimpleData and ExtendedData etc. It contains whole information in tag. But when you need to see the geometry you may require Shapefile. This conversion can be done using Ogr2ogr utility from GDAL (Geospatial Data Abstraction Library) and other GIS software such as QGIS, ArcGIS etc.

Convert kml to shp – Look Details For KML (Keyhole Markup Language) structure with Line feature-

<Schema name="India_roads" id="India_roads">
 <SimpleField name="MED_DESCRI" type="string"></SimpleField>
 <SimpleField name="RTT_DESCRI" type="string"></SimpleField>
 <SimpleField name="F_CODE_DES" type="string"></SimpleField>
 <SimpleField name="ISO" type="string"></SimpleField>
 <SimpleField name="ISOCOUNTRY" type="string"></SimpleField>
 <SimpleField name="Length_km" type="float"></SimpleField>
 <SimpleField name="Latitude" type="string"></SimpleField>
 </Schema>
 <Folder><name>India_roads</name>
 <Placemark>
 <Style><LineStyle><color>ff0000ff</color></LineStyle><PolyStyle><fill>0</fill></PolyStyle></Style>
 <ExtendedData><SchemaData schemaUrl="#India_raods">
 <SimpleData name="MED_DESCRI">Without Median</SimpleData>
 <SimpleData name="RTT_DESCRI">Secondary Route</SimpleData>
 <SimpleData name="F_CODE_DES">Road</SimpleData>
 <SimpleData name="ISO">IND</SimpleData>
 <SimpleData name="ISOCOUNTRY">INDIA</SimpleData>
 <SimpleData name="Length_km">0.3</SimpleData>
 </SchemaData></ExtendedData>
 <LineString><coordinates>77.8277403975188,35.5012774951028 77.8257523065223,35.4995003281062</coordinates></LineString>
 </Placemark>
 <Placemark>

In the above given example, attribute fields are given with their data type. In style tag geometry style shown with color. Extended Data encloses attribute field name with values. In the last coordinates are given for particular line string. In similar way other lines, point and polygon are given in KML.

KML to SHP Shapefile – Convert

• • Go to MapOG Tool  and login with email id or if you are new user then register with a valid email id.
  • After login next step is to  Tap on Switch To and select Converter.
  • Next screen will be opened. Upload your data from system or drag & drop.
  • After uploading your data select the output data. For KML to Shapefile select SHP.
  • If you want your output in different coordinate reference system then click on change CRS.
  • Your converted file is directly published on the map. Download your converted file by clicking download icon.

For step by step approach check the video given below:

Convert from Keyhole Markup Language KML to SHP Shapefile using ogr2ogr utility-

For using this utility you need to install it in your system. To install this utility you can follow given commands,

If you already have install this utility or you want to check availability of this utility you can type ogr2ogr in terminal.

For conversion the given command need to be executed on terminal-

--- ogr2ogr -f 'ESRI Shapefile' Output_sahpefile.shp Input_KML.kml

Here -f defines the output file format and ‘ESRI shapefile’ is driver available.

PHP code for converting KML to SHP shapefile-

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 KML_to_shp($KMLfilepath,$output){
 $query="ogr2ogr -f 'ESRI Shapefile'  $output.gml  $KMLfilepath";
 shell_exec($query);
 }

Generated output in QGIS software-

Change Coordinate System of shapefile generated from kml-

Changing coordinate system of output file can be done with this same ogr2ogr utility. It has various option for SRS (Spatial reference system), given below

-a_srs srs_def:

Assign an output SRS

-t_srs srs_def:

Reproject/transform to this SRS on output

-s_srs srs_def:

Override source SRS

These option can be used in command as-

— ogr2ogr -f ‘ESRI Shapefile’ -t_srs EPSG:32643 (new EPSG) -s_srs EPSG:4326 (old EPSG) shpchange.shp output1.kml
