Shapefile to KML converter

1. Drop the zipped shapefile, or pick the .shp, .dbf and .prj files together.
2. The shapes are converted to latitude and longitude and drawn on the map.
3. Download the KML and open it in Google Earth or any app that reads KML.

Runs in your browser. Files are never uploaded.

Input

A zipped shapefile, or the .shp file picked together with its .dbf, .prj and .cpg.

Output

A .kml file in WGS84 latitude and longitude, with every attribute written as text.

plots.zip: plots.shp, plots.shx, plots.dbf, plots.prj (WGS84) and plots.cpg, holding one polygon with name = Plot 2, commodity = coffee and area_ha = 8.6.

plots.kml, with this placemark:
<Placemark><name>Plot 2</name><ExtendedData><Data name="commodity"><value>coffee</value></Data><Data name="area_ha"><value>8.6</value></Data></ExtendedData><Polygon><outerBoundaryIs><LinearRing><coordinates>-84.528637,9.986941 -84.52898,9.987532 -84.530697,9.987955 -84.53207,9.986771 -84.531813,9.985165 -84.529152,9.985419 -84.528637,9.986941</coordinates></LinearRing></outerBoundaryIs></Polygon></Placemark>

• The .shp is required. Without the .dbf there are no attributes. Without the .prj, coordinates that look like degrees are read as WGS84 latitude and longitude, and others are refused until you add it.
• A coordinate system it can't read is refused rather than guessed. An older local datum (such as Arc 1960 or PSAD56) without its shift to WGS84 can leave shapes a few hundred metres off, and the page warns about it.
• Without a .cpg file, text that isn't UTF-8 is read as Windows-1252 (Latin).
• The KML uses Google Earth's default colours.

The .shp file holds the shapes and is required. Add the .dbf to keep the attributes and the .prj so the converter knows the coordinate system. A zip with all of them works too.

Yes, as long as the .prj file is included. KML always uses WGS84 latitude and longitude, so the converter reprojects the shapes from the coordinate system in the .prj. If it cannot read that coordinate system, it says so instead of guessing, and it warns when an older local datum (such as Arc 1960 or PSAD56) may leave shapes a few hundred metres off.

Yes. Every attribute is written to the KML, and a field called name or description becomes the placemark name or description shown in Google Earth.
