TrafficCamNZ Datafile Update 21 November 2011

In the next hour I will be releasing a data file update for TrafficCamNZ. This datafile feeds into the iPhone/iPad/iPod Touch and Mac Desktop versions of TrafficCamNZ. This datafile contains some important updates for cameras around the world and especially in the USA.

As I developed the application the information about each camera is set to be keyed uniquely on the web address details for each camera, i.e. http://myorganisation.com/camera1.jpg – this creates an issue for me when the web address for that camera changes. What happens is that you end up with two entries in TrafficCamNZ. One for the old camera, and one for the new camera. And I never developed a process that deletes the old cameras.

To clean up the camera list you have three choices (if your want to):
1. delete the application form the iPhone, iPad, iPod Touch – when you resync with you computer the application will reinstall and then go through it’s first launch process. From here you will be prompted to download the new data file. You will have to reset your favorite cameras.
2. from the preferences screen on the iPhone, iPad, iPod Touch – select XML Load – this will delete all existing cameras and load the new set from the web. From here you will be prompted to download the new data file. You will have to reset your favorite cameras.
3. Manually delete the duplicate cameras. This could be a bit of a pain, but it will work. If you “over delete” then another XML Merge will add the cameras you over deleted.

For Mac desktop users you can use the bulk input screen to delete all existing cameras, then reload – use the preferences screen to do this.

Sorry for any confusion I might have created. This was an early development choice and learning experience.
