This R package ingests data (environmental measurements, sensor stations) from the API of opensensemap.org for analysis in R.
The package aims to be compatible with sf and the tidyverse.
This R package ingests data from the API of [opensensemap.org][osem] for analysis in R.
Features include:
- `osem_boxes()`: fetch sensor station ("box") metadata, with various filters
- `osem_measurements()`: fetch measurements by phenomenon, with various filters such as submitting spatial extent, time range, sensor type, box, exposure..
- no time frame limitation through request paging!
- many helper functions to help understand the queried data
- caching queries for reproducibility
The package aims to be compatible with the [`tidyverse`][tidy] and [`sf`][sf],
so it is easy to analyze or vizualize the data with state of the art packages.

## Usage
Complete documentation is provided via the R help system:
Each function's documentation can be viewed with `?<function-name>`.
A comprehensive overview of all functions is given in `?opensensmapr`.
There are also vignettes showcasing applications of this package:
- [Visualising the History of openSenseMap.org][osem-history]: Showcase of `opensensmapr` with `dplyr` + `ggplot2`
- [Exploring the openSenseMap dataset][osem-intro]: Showcase of included helper functions
- [Caching openSenseMap Data for reproducibility][osem-serialization]

## Usage
Each function's documentation can be viewed with `?<function-name>`.
An overview is given in `?opensensmapr`.
A verbose usage example is shown in the vignette [`osem-intro`](https://noerw.github.com/opensensmapR/inst/doc/osem-intro.html).
In short, the following pseudocode shows the main functions for data retrieval:
```r
# retrieve a single box by id, or many boxes by some property-filters
b = osem_box('boxId')
b = osem_boxes(filter1, filter2, ...)
# get the counts of observed phenomena for a list of boxes
p = osem_phenomena(b)
# get measurements for a phenomenon
m = osem_measurements(phenomenon, filter1, ...)
# get measurements for a phenomenon from selected boxes
m = osem_measurements(b, phenomenon, filter1, ...)
# get measurements for a phenomenon from a geographic bounding box
m = osem_measurements(bbox, phenomenon, filter1, ...)
# get general count statistics of the openSenseMap database
osem_counts()
```
Additionally there are some helpers: `summary.sensebox(), plot.sensebox(), st_as_sf.sensebox(), osem_as_sensebox(), [.sensebox(), filter.sensebox(), mutate.sensebox(), ...`.
