# sdcSpatial

_Publishing a raster density map can reveal sensitive values_.

`sdcSpatial` is an opensource R package for creating spatial density (raster) 

maps from point data while protecting the privacy of individual observations. 

`sdcSpatial` offers a `sdc_raster` class that allows to:

- find out which locations are considered sensitive / unsafe for publishing: `plot_sensitive`, `is_sensitive`, `sensitivity_score`.

- apply protection methods that reduce sensitiviy and enhance spatial patterns: `protect_smooth`, `protect_quadtree`.

- remove sensitive locations: `remove_sensitive`.

- extract relative as well as absolute density `raster`s that can be used with visualisation packages, such as `tmap` and `leaflet`: `x$value$mean`, `x$value$sum`, `mean`, `sum`.

## Installation

```r

install.packages("sdcSpatial")

```

To install the current development version of  `sdcSpatial`  with `devtools`

```r

remotes::install_github("edwindj/sdcSpatial")

```

## Example

```{r example, code=head(readLines("./example/protect_smooth.R")[-1],-1)}

```
