viz1090

This is work in progress

There are some major fixes and cleanup that need to happen before a relase:

Everything is a grab bag of C and C++, need to more consistently modernize
A full refactor, especially View.cpp, necessary for many of the new features below.
A working Android build, as this is the best way to run this on portable hardware.

There are also a lot of missing features:

Map improvements
- Labels, different colors/line weights for features
- Tile prerenderer for improved performance
In-application menus for view options and configuration
Theming/colormaps (important as this is primarily intended to be eye candy!)
Integration with handheld features like GPS, battery monitors, buttons/dials, etc.

BUILDING

Tested and working on Ubuntu 18.04, Raspbian Stretch / Buster, Windows Subsystem for Linux (with Ubuntu 18.04), and Mac

Install build essentials

sudo apt-get install build-essential

Install SDL and RTL-SDR libararies

sudo apt-get install libsdl2-dev libsdl2-ttf-dev libsdl2-gfx-dev librtlsdr-dev

Note: On Raspbian the SDL2 package requires X to be running. See the Raspberry Pi section for notes on running from the terminal and other improvements.

Download and build spidr

cd ~
git clone https://www.github.com/nmatsuda/spidr
cd spidr
make clean; make

Download and process map data Grab a shapefile with your desired level of detail from https://www.naturalearthdata.com/downloads

This is a good place to start.

Unzip and copy the .shp and .shx files.

sudo apt install python3 python3-pip
pip3 install geopandas tqdm
python3 mapconverter.py ne_10m_admin_1_states_provinces.shp

This will produce a file mapdata.bin that viz1090 reads. If the file doesn't exist then visualizer will show planes and trails without any geography.

The default parameters for mapconverter should render resonably quickly on a Raspberri Pi 4. See the mapconverter section below for other options.

(Windows only)

As WSL does not have an X server built in, you will need to install a 3rd party X server, such as https://sourceforge.net/projects/vcxsrv/

* run Xlaunch from the start menu
* Uncheck "Use Native openGL"
* Open the Ubuntu WSL terminal
* Specify the X display to use
```
export DISPLAY=:0
```
* Start viz1090 as described below.

RUNNING

Start dump1090 (http://www.github.com/MalcolmRobb/dump1090) locally in network mode:

dump1090 --net

Run viz1090

./viz1090 --fullsceen --lat [your latitude] --lon [your longitude]

viz1090 will open an SDL window set to the resolution of your screen.

RUNTIME OPTIONS

Argument	Description
--server [domain name or ip]	Specify a dump1090 server
--port [port number]	Specify dump1090 server port
--metric	Display metric units
--lat	Specify your latitude in degrees
--lon	Specify your longitiude in degrees
--screensize [width] [height]	Specify a resolution, otherwise use resolution of display
--uiscale [scale]	Scale up UI elements by integer amounts for high resolution screen
--fullscreen	Render fullscreen rather than in a window

HARDWARE NOTES

This software was originally intended for Raspberry Pi devices, and it is currently optimized for the Raspberry Pi 4 with the following configuration:

Raspberry Pi 4
A display:
- Pimoroni HyperPixel 4.0 Display *best overall, but requires some rework to use battery monitoring features of the PiJuice mentioned below
- Waveshare 5.5" AMOLED *this is very good screen but the Google Pixel 2 phone mentioned below has a very similar display for the same price (along with everything else you need in a nice package)
- Waveshare 4.3" HDMI(B)
- Adafruit 2.8" Capacitive Touch
A battery hat, such as:
- PiJuice Battery Hat *I2C pins must be reworked to connect to the Hyperpixel nonstandard I2C breakout pins, unfortunately
- MakerFocus UPS Hat
Any USB SDR receiver:
- Noelec Nano V3
- Stratux V2 *very low power but hard to find

If running as a front end only, with a separate dump1090 server, the best option is to use an Android phone, such as the Pixel 2, which significantly outperforms a Raspberry Pi 4.

viz1090 has been tested on other boards such as the UP Core and UP Squared, but these boards have poor performance compared to a Raspberry Pi 4, along with worse software and peripheral support, so they are not recommended. viz1090 with a low resolution map will run on these boards or even a Raspberry Pi Zero, so these remain options with some tradeoffs.

Of course, a variety of other devices work well for this purpose - all of the development so far has been done on a touchscreen Dell XPS laptop.
