This project aims to map burnt areas within NSW in a way that is useful for bushwalkers. When vegetation is burnt in a bushfire, it generally removes scrub and makes the area easier to travel through for a few years. Knowing where these recently burnt areas are can then assist in route planning for bushwalks. | This project aims to map burnt areas within NSW in a way that is useful for bushwalkers.

+ | ===== Process ===== | ||
+ | * Obtain knowledge for bushfire occurrence - both time and location | ||
+ | * RFS Fires Near Me will detail any active fires, with either a point or rough polygon indicating its position | ||
+ | * Looking through old imagery can also lead to burn area identification | ||
+ | * Capture imagery of burn area | ||
+ | * Best done with EOS Land Viewer | ||
+ | * Free service (with some restrictions), | ||
+ | * Provides Landsat and Sentinal imagery (only Landsat 8 and Sentinal-2 are of interest) | ||
+ | * Limit of 10 ' | ||
+ | * Unlimited downloads of ' | ||
+ | * Provides individual bands, including IR and NIR, along with pre-set band combinations - use Shortwave Infrared | ||
+ | * An alternative is the [[https:// | ||
+ | * Free service, no account required | ||
+ | * Also has Landsat and Sentinal imagery | ||
+ | * Unlimited image views and downloads (need to select geotiff format and geographic spatial reference) | ||
+ | * Only provides true-colour images, no use of IR or NIR bands | ||
+ | * Create burn extent polygons | ||
+ | * Load imagery into QGIS and name file as layer in format of " | ||
+ | * Add polygon by visually inspecting burn area image and capturing full extent within boundary | ||
+ | * Add field data to polygon such as fire name, area, date of image capture | ||
+ | ===== Examples ===== | ||
+ | An example can be found through the link below, where a geojson file has been imported into an online map. | ||

+ | ===== To Do ===== | ||
+ | * Investigate RFS RSS Feed data | ||
+ | * It appears that they supply multiple feeds relating to fires | ||
+ | * Their [[http:// | ||
+ | * See if it's worth collecting this data on a regular basis (say weekly) and then compiling into one big database for reference and / or later analysis | ||
