## Description
### R client for OGC SOS
**Easing the access to environmental time series data from an OGC Sensor Observation Service**
sos4R is an extension package of the R environment for statistical computing and visualization.
sos4R is [available on CRAN](https://CRAN.R-project.org/package=sos4R).
The user can use it to query data from standardized SOS instances (with specific consideration of the OGC SOS 2.0 Hydrology Profile) using simple R function calls.
It provides a convenience layer for R users to integrate observation data from SOS servers compliant with the SOS standard without any knowledge about the underlying OGC Sensor Web Enablement standards.
### Features
**Key Technologies**
- R Programming Language
- OGC Sensor Observation Service 2.0
- OGC WaterML 2.0
- OGC Observations and Measurements 2.0
**Benefits**
- Easier access to environmental time series data
- Automatic generation of SOS requests
- Result handling and parsing into standard R objects
- Convenience API: Data Science oriented functions to load data
## Quick start
```{r quickstart, eval = FALSE}
install.packages("sos4R")
library("sos4R")
# connect to SOS and request metadata
mySos <- SOS(url = "http://sensorweb.demo.52north.org/sensorwebtestbed/sos",
binding = "KVP", useDCPs = FALSE, version = "2.0.0")
# retrieve available phenomena and sites
phenomena <- phenomena(sos = mySos, includeSiteId = TRUE, includeTemporalBBox = TRUE)
phenomena
siteList(sos = mySos)
# retrieve data
getData(sos = mySos,
phenomena = phenomena[5,1],
sites = phenomena[5,2],
begin = as.POSIXct("2018-01-01"),
end = as.POSIXct("2018-01-3"))
```
**Install the development version**
You can install the current development version (= the next release for CRAN) directly from GitHub:
```{r install_dev, eval = FALSE}
#install.packages("remotes")
remotes::install_github("52North/sos4R", ref = "dev")
```
## User guide
The project website is at [https://52north.github.io/sos4R](https://52north.github.io/sos4R).
You can also join the chat at [on Gitter](https://gitter.im/52North/sos4R) if you have any questions.
## Demo
sos4R can used to download observation data or build user interfaces for requesting and rendering time series observations.
The screenshot below shows a demo Shiny application, which you can run locally with
```{r demo, eval=FALSE}
shiny::runApp(appDir = file.path(path.package("sos4R"), "shiny"))
```
## Changelog
The latest changes, updates, bug fixes can be found in the package changelog at [https://52north.github.io/sos4R/news/](https://52north.github.io/sos4R/news/).
