Local NLP Backend vs Show Articles in Map
Side-by-side comparison of two open source alternatives
Local NLP Backend
The backend passively monitors the GPS and scans for nearby WiFis and mobile cells/towers. From this a database of emitter locations is created. When UnifiedNlp / microG request a location from Local NLP Backend, a scan for nearby emitter is initiated and a location determined based on the scan results. Local NLP Backend is a fork of the Déjà Vu NLP Backend with some improvements and a crude UI for configuration and importing / exporting data, including cell lists from MLS or OpenCelliD. This backend uses no network data. All data acquired by the phone stays on the phone, though it may be exported manually. How to use: Local NLP Backend can be used like Déjà Vu: just enable the backend and let it build up the database by frequently having GPS enabled, e.g. using a map app. If you have a Déjà Vu database (you'll need root privileged to extract it), it can be imported in Local NLP Backend. Further import options are databases exported by Local NLP Backend, and cell csv files from MLS or OpenCelliD. Note that the local database needs to be filled, either using GPS or by importing data, before Local NLP Backend can provide locations! In order to speed up building the database, LocalNLP has an optional active mode that enabled GPS when there is no known emitter nearby (low setting) or when any unknown emitter is found (aggressive setting). Note that microG has stopped supporting UnifiedNlp backends with 0.2.28. If you still want to use this backend (or others), you need to use older microG versions. This can only be recommended if you use microG for location only. Personally I use 0.2.10, as with later versions location backends stop providing locations after some time.
Show Articles in Map
Note: You must also install Location Map Viewer to display the results. This app adds the option Show Articles in Map to any app that can shown/send/share a geo location or geo-uri . This app hooks into the android system to intercept "view geo-uri". When getting a geo-uri it asks encyclopedia wikipedia (or travelguide wikivoyage or knowledgebase wikidata or photogallery wikimedia) and shows the results in Location Map Viewer (or in any other installed app that understands the format 'kmz'). Location Map Viewer shows a map with bubbles (or article-icons if enabled/available) for every wikipedia article found. If you click on a bubble you get a popup with a short article description and a button that links to the full article. Here are some f-droid apps that are compatible with Show Articles in Map navigation: OsmAnd, public transportation: Transportr or oeffi translate postal address to geo Acastus Photon Share your current position LocationShare or My Position Required Android Permissions: INTERNET: to download article data from wikipedia or wikivoyage Server .
