 ====== How to work with elevation data in Locus? ======
 ----
-<wrap info>Concerns Locus Map Pro only</wrap>
 Elevation data are necessary for many aspects of work with Locus:
   * base of calculation of route **elevation gain** when [[manual:user_guide:tracks:planning|planning. ]]
   * definition of **elevation of [[manual:user_guide:points|point objects]]** (POIs, geocaches...)
-  * database for **[[manual:user_guide:maps_settings:objects|dynamic elevation tool]]** (displays elevation on the position of the map cursor)
+  * database for **[[manual:user_guide:maps_settings#dynamic_elevation|dynamic elevation tool]]** (displays elevation on the position of the map cursor)
-  * database for rendering **[[manual:user_guide:maps_settings:misc|terrain shading]]**
+  * database for rendering **[[manual:user_guide:maps_settings#map_shading|terrain shading]]**
   * filling elevation of imported **[[manual:user_guide:items|Map items]]** in case the file contains at least one route
   * **elevation of routes** calculated by [[manual:user_guide:functions:navigation:settings|external navigation engines]] (BRouter, YOURS, ..)

-Please do not confuse with **current altitude** that is obtained from GPS data together with values from the barometric pressure meter in your device (if applicable), [[manual:user_guide:tools:altitude|see more >>]]. Current altitude values are also used for calculating elevation gain in recorded tracks and are available also for Locus Map Free users.

-===== Sources =====
+===== Where to get them? =====
-Elevation data can be **streamed online** or downloaded for **offline use**. The only advantage of streamed data is their coverage of the seas' and oceans' bottom (underwater depth). Otherwise it consumes your FUP and is slower than displaying downloaded data.
+To use all features above, it is necessary to **download elevation data**. There are a few methods on how to get them:
+==== Offline maps ====
+LoMaps and other offline maps from our map partners offered in [[manual:user_guide:locus_store:about|Locus Store]] in packages cover the whole World. **Each map package contains elevation data that can be downloaded separately for free:**\\ {{ :manual:faq:elevdata.png?nolink |}}
-Data for offline use can be downloaded several ways:
+==== Creating or editing a point of interest ====
-==== Offline map elevation data ====
-LoMaps and other offline maps by our map partners offered in [[manual:user_guide:locus_store:about|Locus Store]] in packages cover the whole World. **Each map package contains elevation data that can be downloaded separately for free:**\\ {{ :manual:faq:elevdata.png?nolink |}}
-==== Online - creating or editing a point of interest ====
   * [[manual:user_guide:points:add|Add a new point of interest]] or open detail screen of an existing point located in the area that we want to cover with elevation data
   * find //Elevation// field and if it is empty, tap the button GET next to it
-  * Locus Map asks if you want to fill elevation to selected object and download necessary HGT file (from Google)
+==== Group of points ====
-  * select if you want to download it or display online\\ \\ <WRAP round tip >
-This method is demonstrated in this **[[https://youtu.be/xRO_UEsQQrU|tutorial video >>]]**
-</WRAP>
-==== Online - group of points ====
   * select points (check them) in a desired point folder
   * tap {{:manual:user_guide:ic_arrow_simple_up_alt.png?nolink&30|}}More and {{:manual:user_guide:ic_fill_altitude_alt.png?nolink&30|}}Fill elevation in bottom panel
-==== Online - a track ====
+==== Track or route ====
-  * open a track detail screen
+  * open a track/route detail screen
   * tap {{:manual:user_guide:ic_arrow_simple_up_alt.png?nolink&30|}}More and {{:manual:user_guide:ic_fill_altitude_alt.png?nolink&30|}}Fill elevation in bottom panel
-==== Elevation data from an external website ====
+<WRAP center round info>
-  * go to some of websites that provide digital elevation data in HGT format, e.g. [[http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm|here:]]\\ \\
+==== Custom elevation data sources ====
-[[http://www.viewfinderpanoramas.org/Coverage%20map%20viewfinderpanoramas_org3.htm|{{ :manual:faq:viewfinder.png?nolink |www.viewfinderpanoramas.org}}]]
+  * **[[http://viewfinderpanoramas.org/dem3.html|Viewfinderpanoramas.org]]** - SRTM3 data enhanced in mountainous and polar areas. Resolution 3".
-  * select area of map shading and download it
+  * **[[https://sonny.4lima.de/|Sonny's LiDAR Models of European Countries]]** - very accurate data obtained from LiDAR mapping missions, covering many European countries. Resolutions 1" and 3”.
-  * copy the elevation files to //Locus/data/srtm// directory
+  * store the data in Locus/data/srtm directory and **restart the app**
