GPS tracking: Knowing where you were, is and wanted to be…
Continued: To find out how the pair of iPod touch and external GPS in practice proved, I used several hikes and experimented. Starting point was a 100% loaded iPod touch, the end of the trip was for me when the battery was completely empty. The deactivation of the live card extends the usability to twice, but without map one can orient themselves badly. With connected Gum Pro (accessory battery) you get almost tenfold usability but must also carry the battery with it.
Overview of running times:
With activated live card: approx. 70 minutes
Without live card: about 150 minutes
With activated live card and Gum Pro: approx. 700 minutes
With the Gum Pro, a very long recording was possible, so the total running time was determined in four stages.
Interesting insights in the hot temperatures during the hike: Sometime on the iPod came the error message that he can not be loaded with this accessory. Hmm, exactly that had the battery but already done for several hours. The touch was slightly warmer than usual, so I removed the silicone sleeve and after a few minutes of cooling the battery was recognized as a certified charger again.
In this area of Trails ( AppStore-Link ) you will find all necessary settings to get the best possible result. These can be set separately for four areas: jogging, hiking, cycling and motorized. The following settings can be made: Minimum accuracy-if this is exceeded, no recording is made and the distance is spared by outliers due to poor reception. In the distance filter, the minimum distance between two points can be set and thus the number of recorded points can be reduced. But on all devices on which Trails runs is probably more than enough space, so an artificial deterioration of the recording should be avoided = distance filter. Whether you disable the live card you have to decide for myself, it is a necessity for me, because without map I need also no trails.
For the track recording is always a GPS-logger in the backpack, which can last several days, without which I have to worry about the battery life. If traces are used for pure route recording, the live card can be deactivated and the runtime can be doubled. In the map settings, you can set the zoom depth-if you drive in the car the map can be zoomed out a little further, while hiking I want to see as many details as possible. The map display itself can be switched between the standard OpenStreetMap card and a topographic map with cycle paths. In the latter the bicycle paths are highlighted. In the last setting the unit of measure can be changed between Anglo-American (miles) and Metric (kilometers). According to this selection, the unit of velocity is also influenced. At the bottom of the settings, you can enter an email address to which the exported routes should be sent and the access data for your own EveryTrail account.
Special case iPad Trails
on the iPad should offer the same functionality as on the iPhone and iPod touch, but the comfortable card download via a range selection is unfortunately missing. But still, it’s really fun to move, zoom, or watch the track with the big display. As a specialty Trails on the iPad offers the possibility to create own routes by setting waypoints. These can then be transferred to trails on the smaller devices and used as a background path.
A very practical app for people who like to hike or ride a bike! Regardless of whether the distances covered are recorded or an existing one is to be traced, Trails is helpful in both cases. Nice would be a general backup, eg on Dropbox, for all recorded/imported routes.Because exporting each one individually and then importing it again is quite time-consuming. This is necessary if trails do not work properly after an update and need to be reinstalled. Before the purchase, everyone can form their own opinion about the program, because there is also a free Lite version (AppStore link).
