Security alert........I had not heard of this and wanted to share it.
I did not know where to post this, I thought this was extreemly important for those with outdoor gurilla grows seeing how it is spring time. If ya take a pic with your cell phone anyone can find your grow plot. Look at this webpage. Here is the first paragraph from the page located here.
http://wiki.forum.nokia.com/index.php/Extract_GPS_coordinates_from_digital_camera_images_using_PHP
Introduction
The photos taken with digital cameras, mobile or otherwise, contain a lot of interesting information that is stored inside the image in a metadata format called EXIF (exchangeable image file) . This data makes each image unique. EXIF data contains information like, model of the camera, the aperture used, ISO level, and if the flash was used or not.
Amongst the information in the EXIF data will be geolocation; latitude and longitude of the place that the photo was initially shot. This information would be useful e.g. in conjunction with a mapping API to show the image on the actual geolocation over the world map. There are already online photo sharing communities e.g. Panoramio, locr or Flickr, which do allow uploading of geocoded images or to add geolocation information online.
Nokia has developed a series of mobile phones that are equipped with a GPS receiver and therefore able to tag all captured images with the location Note that on a mobile device that supports it, one has to remember to enable the GPS location feature in the Camera application setup.
The main objective of this article is to provide an example of how to extract the data in the digital camera image file, and place the data into an array, which can be then used further. The script is written in PHP and can run in a Windows / Linux environment, hosted either locally or remotely that is configured to support PHP. In the pre-requisites it is mentioned that the PHP needs to be configured to support reading the EXIF information. How to configure this, will be explained further in this wiki article. Please note that the PHP script in this Wiki article represents only basic functionality to perform the tasks.
Be safe out there
