Convert OCD to KML

Understanding the OCD and KML file formats

OCD files are typically associated with OCAD, a specialized software used for creating and editing orienteering maps and other types of cartographic documents. These files store map data, symbols, and layout information in a proprietary format.

KML (Keyhole Markup Language) is an XML-based file format used to display geographic data in mapping applications such as Google Earth and Google Maps. KML files can contain points, lines, polygons, and images, making them ideal for sharing and visualizing spatial data.

Why convert OCD to KML?

Converting OCD files to KML allows you to share orienteering maps and other cartographic data with a wider audience using popular mapping platforms. This conversion is essential for integrating specialized map data into web-based or mobile mapping applications.

How to convert OCD to KML

Direct conversion from OCD to KML is not natively supported by most software. However, you can achieve this in a two-step process:

1. Export your map from OCAD to a common GIS format such as Shape (SHP) or DXF:
• In OCAD, go to File → Export → Shape or File → Export → DXF.
2. Convert the exported file to KML using GIS software like QGIS:
• Open QGIS and use Layer → Add Layer → Add Vector Layer to import your SHP or DXF file.
• Right-click the layer and select Export → Save Features As....
• Choose KML as the output format and specify the destination file.

Recommended software for OCD to KML conversion

• OCAD: For exporting OCD files to SHP or DXF.
• QGIS: A free, open-source GIS tool for converting SHP or DXF to KML.

Both OCAD and QGIS are reliable and widely used in the mapping community for such conversions.

Summary

To convert OCD files to KML, export your map from OCAD to SHP or DXF, then use QGIS to convert the file to KML. This workflow ensures your orienteering maps can be viewed and shared in popular mapping applications.
