When you remember where you took a photo, wouldn’t it be great if you could geocode it by simply dropping it on a map?
In HoudahGeo 5, you can do just that. In the video demo, I am geocoding a series of photos taken at Taj Mahal. I distinctly remember walking from bag check to the great gate. On the way, I took a few photos as the majestic site revealed itself.
This summer, we travelled to Florida. I did not bother to adjust the clock on my camera to match local time. I left it set to my home time zone: Central European Summer Time (CEST).
When the time came to geotag photos from the trip, I just had to tell HoudahGeo that the camera clock was set to CEST. With this extra bit of information, HoudahGeo was able to figure out at what exact time each photo was taken. It then matched these times to GPS track logs to find where the photos were taken.
This photo of a Key Deer was indeed taken on Big Pine Key, Florida.
The Places maps in Apple Photos is a great way to find and explore photos.
Geotagged photos taken with iPhone or another GPS-enabled camera are automatically added to the map. To add other photos, you can assign them locations in Apple Photos. You will, however, also want to geotag these photos.
How is geotagging different from assigning locations in Apple Photos?
The newly released macOS 10.12 Sierra includes a major update to the Apple Photos application. In Photos 2.0, the Places feature makes a comeback. The Places album lets you explore your photos on a beautiful world map. The new Memories feature also includes a map showing where the photos in the collection where taken.
Starting with Photos 2.0, it is now possible for HoudahGeo to update places information in the Photos library. This allows you to use the many options HoudahGeo offers for geocoding to add locations to photos in your library.
In order to save battery, many GPS-enabled cameras power their GPS receiver only once you turn on the camera. It then takes anyhwere from a couple of seconds to several minutes for the GPS to know where you currently are.
If you take a photo during this power-up phase, the camera is left with the option to use a previously recorded GPS location or forgo geotagging the photos.
At the end of the day, you will have a set of photos where some images lack geotags. This can easily be fixed with HoudahGeo.
In Mac OS X’s Finder, you can save searches as “Smart Folders”. These give you quick access to all your files that meet certain criteria. For example, all Microsoft Word files modified this month. All JPG photos taken with a specific camera. Or all e-mails you’ve received from certain senders within the last seven days.
Because Mac OS X Smart Folders are actually saved searches, they differ from regular folders: they don’t actually hold anything – they only list files stored elsewhere. The content of Smart Folder is not static but dynamic. It is updated continuously as new files come to meet the smart folder’s search criteria. This means that its content changes every time files on your Mac are added, changed, or removed.
With HoudahSpot (4.1 or later), you can easily set up a search and export it as a Finder Smart Folder.
Manually geocoding a long list of photos can be daunting. With HoudahGeo it’s a snap. Follow the workflow outlined below and you’ll be done in no time.
The workflow takes advantage of the fact that the distance travelled between two photos is often rather short and easy to retrace. Once you have determined the location of the first photo, you just need to make incremental adjustments to geocode subsequent photos. It takes but a nudge to the map and a click for each photo.
In HoudahSpot, snippets let you to set aside frequently used combinations of search criteria. HoudahSpot comes with a few pre-installed snippets, but you can also define your own.
Snippets can hold a single search criterion or a group of criteria that serve a certain purpose. The pre-installed snippet “Date Created range”, for example, holds two criteria in an “All of the following are true” group: “Content created before” and “Content created after”. Use this snippet whenever you want to find files created in a range of dates.
