Exporting Objects

in this lesson

CalTopo Export functions include the ability to export static files in GPX, KML, or GeoJson file formats. It also includes the ability to copy the current map to a new map and to obtain a link for dynamic updates to view CalTopo objects and layers in Google Earth.

You can export objects to a file from a map whether the map is saved or not. We will look specifically at using Google Earth with CalTopo in the next major section.

Exporting Files

Exporting to a file is simple. Access the export menu by clicking export at the top of the map object column, then select the format from the dropdown menu. Then choose or de-select the objects to include in the file. The export dialog box works the same way as the import box we covered earlier. Click EXPORT in the bottom right to finish, and the file will download to your computer.

For a review of files types and the type of information they contain, go back to that section.

Access the export menu by clicking export at the top of the map object column, then select the format from the dropdown menu.

Below are two images of exporting the same map objects via GPX or KML as you see in the first image vs exporting the same objects via GeoJSON or Copy Map as you see in the second image. If you look closely, you will see that the GeoJSON/Copy Map export screen contains a section for “folders” in addition to marker and shape objects. When you open a GeoJSON file, the folder structure and organization from your original map will be preserved.

Copying to a New Map

To copy objects to a new map, select the option from the dropdown menu that says “copy to a new map” and select the objects to include, just the same as for importing or exporting. When you hit OK, a new browser tab will open with the selected objects on a new map. This map is not automatically saved; you need to save it manually to preserve it for future use.

Exporting Objects to a File in the App

To export objects from a map to a new file on your mobile device, go first to the map objects menu. Then use the icon button at the top right to start the export. Next you will choose the file type to store your map items as. Finally, choose which map items to include in the file using the checkboxes, and click export to create the file.

After you tap the export button, the share options on your phone will open. From there you can save the file directly to your phone, or send it via text or email, or many other options depending on your phone apps and settings. You must choose something or nothing will happen with the file. The export process will fail.

In the mobile app, you can export a file but you cannot copy to a new map or create a network link as you can in the web browser.

Exporting to Older GPS units

Just like with importing, most modern GPS units can function as a USB device, though it may require digging through some menus to find the setting to allow it. If your GPS model is too old for this function, you can try using the GPSIO program, which you can access and install via the link in the export menu.
