The program for constructing a route profile is developed for the Android OS.

In January, I conducted radio communications in the VHF range of 433 MHz at a distance of up to 20 km, using a program for calculating the altitude profile to select a position "Elevation Profile".

An acquaintance was at home, and I drove with a car VHF antenna on the roof, in the Krasnoye Selo area (altitude 100 meters above sea level). Station power on both sides is 5 W. To determine the most advantageous point on the map, I used Elevation, because... “by eye” the top of the mountain is not visible due to the numerous private houses blocking the view of the area.

"Elevation Profile" - a program for building an elevation profile

I found it not on the Play Market, and not in Rustore, where they are not available, but on APKpure. Version 1.6.2, package name:
*com.shasha.elevationprofile
Application for Android 4.1 - 9.0, APK file size 3.35 MB.

Download Elevation Profile from Apkpure.com

Using the program

Setting the start and end points

Origin- starting point
Destination- end point

In the right corner there is an extreme icon - set the type Direct.

Then,long press we set the starting and then ending points on the map.

The bottom of the window will be built elevation profile between the starting and ending points.

The starting point is indicated by a green marker,
final - red.

If you click on the profile, a yellow marker will appear indicating the current position on the route (convenient for finding obstacles in the path of VHF radio waves).

Switching maps

You can switch the type of map used: diagram or satellite, by clicking on the button with the images of layers.

• Road - topographic map

• Satellite - map based on satellite photos

• Terrain - topographic map with relief designation

• Hybrid - a hybrid of a satellite and topographic map.

  

Adding an intermediate point (repeater)

If there is an obstacle between the receiver and transmitter, the signal cannot pass through directly. To solve the problem, a repeater is used, which is located at an advantageous point from which direct visibility of the transmitter and receiver is ensured.

To add a waypoint:

• first set the starting and ending points (origin, destination)

• press and hold your finger on the screen - select a menu item Add as a waypoint

  

The program can be used not only to calculate VHF radio communications, but also to plan hiking routes. For example, if there are water obstacles on the way, passage is not possible without pedestrian bridges or crossings. Thus, the Cable-stayed Bridge across the Neva is intended only for road traffic.

Purple marker appears when you long press on the map, is intended to indicate the current place of interest and is not used in calculations.
