go-california-landscapes
Go package to parse posts from the California Landscapes bot and create new JPEG images with embedded EXIF data derived from those posts.
Motivation
I love the California Landscapes bot and I wanted to have an archive of images that I especially liked.
Tools
$> make cli
go build -mod vendor -ldflags="-s -w" -o bin/fetch cmd/fetch/main.go
show
$> ./bin/fetch -h
Fetch one or more posts from the California Landscapes bot and create a new JPEG image with EXIF data derived from the post.
Usage:
./bin/fetch [options] url(N) url(N)
If url(N) is "-" then the list of URLs to fetch is read from STDIN. Valid options are:
-destination string
The destination folder where images should be written. Default is the current working directory. (default ".")
-verbose
Enable verbose (debug) logging.
For example:
$> ./bin/fetch -verbose https://botsin.space/users/CALandscapeBot/statuses/112950415212901085
2024/08/31 12:34:20 DEBUG Verbose logging enabled

Of, if you upload the image to Flickr and you have both the settings to read EXIF data and automatically geotag your photos enabled you'll see something like this:

To do
The following tasks are on my "to do" list in no particular order and with no expected timeline. Any help or pull requests are welcome:
-
Make it possible to run this as a AWS Lambda function.
-
Use the gocloud.dev/blob abstraction layer to write files to both the local file system and remote storage platforms.
-
Add the ability to post images directly to Flickr.
-
Figure out what value(s) I need to pass to the dsoprea/go-exif package in order to write
GPSAltitudeReftags.
