Import Data

Remote KML, KMZ, KML Network Link, GeoRSS, GPX

Enter the URL (starting with http://) of the file residing in another web server in text box. To find a url of a file with a download link in another web page, right-click on its link and copy its url (make sure the url ends with the right filetype, eg. .kml or .kmz). Google Maps support for KML is more limited than Google Earth; for detailed explanation check here and here.

Local KML, GPX

Open KML file with a text editor (e.g. wordpad), select and copy the content and paste in textarea. GPX file type is not supported at this time. You can open your GPX or KMZ file in Google Earth, then save them as KML and upload here.

Fusion Tables

Use Google Tables search page to find public fusion tables or tables in web pages. You can import the data from a web table to fusion tables. Other file types such as KML, spreadsheets and CSV can also be imported into fusion tables. Once you open a fusion table, under 'File --> About' copy the 'Encrypted Id' (main Id) of the table and paste in textbox below. Find the column that has location data (e.g. geometry). For the where clause write a condition based on a desired column and its values. Columns having values starting with number don't need quotes in the query statement (e.g. ridership > 50, where ridership is the column name and 50 is value); however for a column with text values you need to put quotes around the query statement and the value itself (e.g. "state='MA'", where state is column name and MA is value).
