A 'lightweight' GPX, TCX, KML/KMZ- and FIT File viewer app that is deliberately limited to the basics.
- Enter distance and altitude values
- Calculation of the slope percentages
- Assignment of a title (= caption of elevation chart)
- Elevation chart creation (imperial or metric axis are supported)
- Save/restore the created profile data (XML format)
- Calculation of the ascent-/descent meter (feet) (adjustable hysteresis factor!)
- Import of * .gpx, * .tcx, *.kml (kmz) and * .srp files (GPS based data)
- Track display as map view (OSMDroid)
- Track animation (Virtual ride)
- (New) Compatibility with the also very lightweight app 'GPS Logger' (BasicAirData)
- (New) (Garmin) Fit File Import (only GPS coordinates, altitude values, SPD, distance and time stamp)
- (New) Improved sharing functionality -> for example, the imported data can be transferred to the Garmin Connect app as a route via the sharing function.
- (New) Optional display of the speed curve (can be faded in and out)
- With this elevation chart creator you can create on-the-fly elevation charts, you only must be aware of distance and elevation values.
- The imported GPS data can be visualized with the GPS viewer.
- With the sharing function, the imported GPS data can be converted internally into GPX format and transferred to other apps (the FIT file format is currently still supported by relatively few Android apps, so this 'conversion' into GPX format can be very useful).
- Using the integrated browser mode, it is possible to browse through the GPX/TCX/KML/FIT files on your device in order to better manage route/track data and, for example, to pass it on more easily to the Garmin Connect app (unfortunately since Android 11 access to the download folder is restricted for normal apps (= no system apps) -> therefore it is best to store the track/activties files in a special folder on your devices -> e.g. this could be a sub folder within the download folder).
This app needs some special PERMISSIONS:
Write and Read permissions [WRITE_EXTERNAL_STORAGE, READ_EXTERNAL_STORAGE]
a) for optional storage of the height profile data
b) for creation of an optional screenshot graphic if you want to use the share functionality, which does nothing else than transfer a screenshot graphic file to another app
c) for caching the map tiles (OSMDroid)
Location data [ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION]
ONLY needed if you want to use the 'JumpTo'-Home functionality in the map view, which does nothing more than center the map to the last known location! This app DOES NOT (currently) offer any GPS logging (tracking) functionality!
Network permissions [INTERNET, ACCESS_NETWORK_STATE]
Required to download the map tiles.
ATTENTION: When using the map view, DATA (map sections, so-called tiles) are DOWNLOADED from the Internet. This can lead to corresponding costs when using a mobile data connection. A WLAN connection or a mobile data flat rate is therefore strongly recommended!
Perhaps it is useful for some users, that's the reason, why this app has now been published to the public.
Please no discussions about, it is a free app without the claim to be of any value to every single user. For me it works :-)
An online manual (currently only in German, but Google translate service would surely help) is available on my blog: https://wrpsoft.blogspot.com/2021/02/wrpelevationchart-anleitung.html
