Apple recommends that if 80% of users don't need a setting, then don't include it. This helps simplify the App, but... our users demand more. So these Advanced Settings are for users that demand more.
They may be a little confusing. I hope this doc helps explain them. But the golden rule is: unless you're really looking for a specific feature, then just stick to the regular Settings ^_^
Size of photos saved in the App – Size of the "main" photo (in Megapixels) stored with GPS Log. 0.4M and 1M are good settings. However, the bigger the size, the more space on your iPhone GPS Log will use over time
Also save a full-sized copy to the App directory – If set, the full sized photo is stored in GPS Log in addition to the version above. These are stored in the CameraRoll/ directory within GPS Log (see FTP). It is designed that you delete the images from this directory after copying, else the space used by GPS Log will grow very high.
JPEG Quality – JPEG quality setting of all photos saved by GPS Log (excluding ones to the iPhone Camera Roll - below). 0.95+ is a good setting for high quality photos.
Save full-sized photo to iPhone Camera Roll – Saves the original photo to the iPhone's camera roll. Not recommended to use (but you can if you want) with the Also save a full sized-copy to the App directory (above).
Use legacy camera (with photo review) – Uses the "standard" iPhone SDK camera overlay, including the review of photos before saving
- Legacy Crop – If set, you will be prompted to crop photos
The settings here help implement specific use-cases where you want GPS Log to perform some actions automatically.
On new Log Entry, open:
- None – nothing happens
- Photo – opens the camera. You can always just cancel it.
- Title – opens the title for editing
- Tags – opens the tag edit screen
- Note – opens the note for editing
Automatically start a new Log Entry on App launch – when GPS Log is launched, a new entry is logged (unless you previously exited GPS Log with an unsaved entry) Automatically save and close new Log Entries – if set, new log entries are automatically closed and saved (unless you edit them)
- after how many seconds? – the number of seconds the entry will be automatically closed with the parent setting. Choose a value here that is big enough that there is sufficient time to get the fix, and small enough so that the fix is saved before you move too far (e.g. if you're in a car).
Immediately acquire a GPS fix on App launch – when GPS Log loads, starts getting a location fix. This speeds up getting the location fix if you create a new entry, or use the map feature. However, it uses a little bit of data, and some battery. For most users this setting is recommended, as it is very likely you will need a location fix sooner or later using GPS Log. If Minimize Data Usage is set, this feature has no affect.
Units – Automatically set to Imperial if your iPhone's local is set to the USA.
Record the heading using the iPhone compass – Also records heading in the log entry
Display the heading in the Log Entry screen – Records and displays heading in log entry
Warn if location is inaccurate – warns when saving an entry with an inaccurate fix
- Warn when accuracy worse than – accuracy values greater than this are considered inaccurate for the purpose of the parent feature
Manual timestamp editing – if set, date/times of the visits are entered using a keyboard, not a picker (takes longer for minor changes, but necessary for setting dates that are a long way in the past)
Auto capitalize title words – if set, when entering the title, all words have their first letter capitalized
Some regions, e.g. China have inaccurate maps. That is, the maps don't line up with the satellite imagery (and GPS Fix). This setting attempts to correct these errors.
This setting has no affect in other regions, and is safe to leave 'ON'.
Apply region-specific map corrections – Applies the offset correction processing
Update Map Offset Data – Downloads the latest map offset data from the GPS Log server
The Custom Server field should be blank. Please don't use this setting. If you want to hack GPS Log, you can write a Custom Service instead.
FTP Data Transfer – Starts a FTP server that you can connect to from your Mac or PC (provided they are on the same Wifi network) to download GPS Log data and photos. Read more: GPS Log FTP Utility operating instructions.
Reset All Settings – Resets all settings to default. Handle with care, this also resets all your Share services, history, export history, etc.
Delete All Data – Deletes ALL data i.e. Log Entries from GPS Log!
