I'm using WP Geo plugin in conjunction with the Geo Mashup plugin. On a form I have used an identifier (geocodedtc) for a post custom field in the Geo Mashup plugin. Using gravity forms I have created a post form that passes simply a City name to the custom field. Geo Mashup recognizes this and inserts the pin automatically on my global map and links directly to the post. All geo data on that city for lat/long, district, state etc is shown on the map below the post edit screen just below the WP Geo map. To activate the WP Geo map on a post I now have to simply copy the lat/long into the search box of the WP Geo interface and the post is then populated with it's own specific map. It would be great if this could be automated yet I understand if a user passed the lat/long into the template WP Geo would pick that up, but it's asking a lot for a lay user to figure that out.
Looking forward to any ideas about this need.
