# rviz_satellite

Rviz plugin for displaying satellite maps at the position of a `sensor_msgs/msg/NavSatFix` message.

> **_NOTE:_**  Looking for the ROS1 version? Checkout the ros1 branch!

## Usage

Add an instance of `AerialMap` to your Rviz config and point it to a `sensor_msgs/msg/NavSatFix` topic.

Map tiles will be cached to `$HOME/.cache/rviz_satellite`.

At present the cache does not expire automatically - you should delete the files in the folder if you want the images to be reloaded.

Currently, the [OpenStreetMap](http://wiki.openstreetmap.org/wiki/Slippy_map_tilenames) convention for tile URLs is supported.

This e.g. implies that only raster tiles (no vector tiles) are supported.

To try a demo, run the following commands to make Rviz circle around a geo point you define.

```bash

ros2 launch rviz_satellite demo.launch.xml

```

You should see a view like the following.

Here, the coordinates are 48.211486, 16.383982 (Vienna), using OpenStreetMap tiles.

## Tile servers

You must provide a tile URL (Object URI) from which the satellite images are loaded.

The URL should have the form `http://server.tld/{z}/{x}/{y}.jpg`.

Where the tokens `{z}`, `{x}`, `{y}` represent the zoom level, x coordinate, and y coordinate respectively.

These will automatically be substituted by rviz_satellite when making HTTP requests.

Tiles can optionally be loaded from a local filesystem if downloaded beforehand

for cases where robots do not have internet access. For example, the file URI

`file:///tmp/tile/{z}/{y}/{x}.jpg` can be used to load files from the `/tmp/tile` directory.

rviz_satellite doesn't come with any preconfigured tile URL.

For example, you could use one of the following tile servers:

* OpenStreetMap: https://tile.openstreetmap.org/{z}/{x}/{y}.png

* TomTom: https://api.tomtom.com/map/1/tile/basic/main/{z}/{x}/{y}.png?tileSize=512&key=[TOKEN]

* Mapbox: https://api.mapbox.com/styles/v1/mapbox/satellite-v9/tiles/256/{z}/{x}/{y}?access_token=[TOKEN]

For some of these, you have to request an access token first.

Please refer to the respective terms of service and copyrights.

## Options

- `Topic` is the topic of the GPS measurements.

- `Alpha` is simply the display transparency.

- `Draw Under` will cause the map to be displayed below all other geometry.

- `Zoom` is the zoom level of the map. Recommended values are 16-19, as anything smaller is _very_ low resolution. 22 is the current max.

- `Blocks` number of adjacent tiles in addition to the center tile to load, 8 maximum.

- `Timeout` specifies a timeout since the last received message timestamp, after which the map will be faded out; disable by setting to 0.
