GIS-extraction (Currently in development)

This script gives worked examples of how to extract GIS information in R.

Overview:

Currently functions to extract:

1. Setup your workspace

- Import camera data
- Determine the UTM code from Lat/Long coordinates
- Create a shapefile of camera locations (using sf)

2. Extract trail features from OpenStreetMap (OSM)

3. Extract elevation at sites (including standalone download of 25m CDED raster)

4. Calculate distance to trails, roads, linear features

5. Calculate density trail/linear feature in buffer

6. Determine terrain ruggedness (Vector Ruggedness Measure: VRM)

7. Map making example in GGPLOT

To-Do:

• NDVI
