Search returns error
The Search function in TPE for iOS 2.5.1 or earlier (e.g. search for a place name, such as ‘New York’) may not work as of Sep 10 2013. This is due to a legacy web service being turned down.
This is fixed in the 2.5.2 update.
Moon illumination is shown only for midnight UTC for the selected date, rather than in the local time zone.
Hints and tips
Current location information
By default, TPE for iOS will display your current location, if you give the app permission to use location data from your device. On iPod Touch, location will be established using your WiFi connection, if available. On iPhone, the built-in GPS chip is used. TPE tries to get a location accurate to within 100m/328ft. When using the “Go to current location” button, the button will remain depressed until a sufficiently accurate location is found and then it will auto-reset (unless you reset it first, or you move the map position manually). TPE isn’t designed to calculate sun and moon position on the fly as you’re driving along in a car – there’s too much involved, plus the data would hardly change all the while it used up your battery power.
Can I drag the map marker?
Yes. Tap and hold the marker for a moment before dragging. The iOS needs a moment to work out if you’re intending to drag the map underneath the map marker or the map itself. Remember, the cross-hairs at the base of the marker (which appear while dragging), show you precisely where the pin will drop when released.
TPE for iOS supports offline use. To get the most out of the app when offline, you should follow a few guidelines:
- Save the locations you will need to use. This ensures that TPE has stored the timezone and elevation above sea level (these are required to provide the most accurate data).
- Select one of the offline map options (OpenCycleMap Topographic, MapQuest OpenStreetMap, or MapQuest OpenAerial) in the settings page within TPE
- Pan and zoom the map to cover the areas you will need to view when offline. Doing this will save the map tiles to your device for use when offline. (You should ensure that the Offline Store on the TPE settings page is enabled before doing this.)
If you are offline and didn’t view the required maps areas in advance, it’s possible the map image tiles will still be in your device’s local cache, but you can’t rely on it. Use one of the offline map types, and view the map tiles you need in advance, for reliable map access when offline.
TPE will look up the local time zone for wherever you are looking on the planet, so you don’t have to second guess. However, it needs an internet connection to do that. If there isn’t one available, you will be prompted to specify a time zone manually.
Finally, TPE also looks up elevation above sea level for both primary (red) and secondary (grey) map marker locations. Elevation above sea level affects the actual time of rise/set and apparent position of the sun/moon in the sky, due to atmospheric refraction. If there’s no internet connection, TPE will assume that the location is at sea level (which is what very many sunrise/set calculators do all the time), and the data will be very slightly less accurate as a result.
For the secondary map marker, knowing the elevation above sea level is essential – this is how you determine the angle of elevation to a nearby mountain-top, for example. With no internet connection, the geodetics information cannot be determined.
Support for TPE for Android
Error on searching for place name
If you receive an error when searching for a place name, it is possible that the Google web service supporting this function is temporarily unavailable.
In other cases, we have seen that some users have to restart their device in order for the search function to become available again.
If you have trouble searching for locations, please try waiting an hour or two, and/or restarting your device. If search is still not working, please e-mail us at the support address above
Unable to find Google Play Services on Android Market
TPE for Android 1.1 and above requires Google Play Services to be installed. Some older Android devices may still have the Android Market app installed, instead of the more modern Google Play store app.
A bug in the Google Maps API v2 means that it assumes that you have Google Play Store installed and as a result clicking the “Install” button will either do nothing or crash an app in this case. TPE attempts to detect if you have the old Market app installed and presents a different install message that should direct you to the Android Market to install Google Play Services.
Here is the direct link for Google Play Services:
- Using the Google Play store app: https://play.google.com/store/apps/details?id=com.google.android.gms
- Using the old Android Market app: “market://details?id=com.google.android.gms”
If you can’t find Google Play Services via the prompts presented in TPE, please click on the appropriate link above, depending on whether you have Google Play or Android Market on your device.
If you are unable to get Google Play Services installed on your phone, please email us for support.
TPE for Desktop Web App
We’ll be adding support information specific to the web app here. In the meantime, if you’re having any problems, please email us at firstname.lastname@example.org with details.
- Slow performance after switching pages multiple times: the web app may load more slowly after switching between pages multiple times due to increasing memory consumption. In most browsers, this can be resolved by reloading the page manually. Internet Explorer 11 may need to be restarted to resolve this condition.
TPE for Desktop (Legacy Adobe AIR app)
The legacy Adobe AIR app is no longer supported. Google disabled Google Maps for Flash API on 2 Sep 2014 and the old desktop app is no longer functional.
