v0.1
The TreeFindr project is aimed at providing an open-source pathway to estimating forest biometrics from rasterized forest height profiles. It is currently in the early stages of development as a QGIS script with an accuracy assessment in R.
- Plot Code:
Used to identify outputs. Can be any string, in this case the format is two letters followed by a number.
- DSM:
The digital surface model layer. A raster height map featuring vegetation.
- Mask Image:
(Optional) A binary raster image that indicates desired image regions to include in analysis (Include = 1, Exclude = 2). Must ensure 'Use Mask' option is checked in order to use.
- Segmentation Threshold:
(Default = 4) Seed to saddle difference in watershed segmentation. Higher values result in more segments merging together.
- Clean Threshold:
(Default = 1.4) Threshold for v.clean algorithm. Higher values result in fewer remaining small areas.
- Set temp Directory:
Choose desired directory to store intermediate files. I have never tried not using this so the 'optional' tag may in fact be incorrect. Useful for identifying the source of errors in the processing pathway.
- Tree Crowns:
The output vector layer indicating tree crown areas.
- Stem Estimations:
The output vector layer indicating estimated stem locations as points.
- Only tested with ENVI formatted height profile as input height field. For some reason does not work with BCAL lidar height profile outputs.
- Reqires the OSGeo4W and SAGA modules to be properly installed within QGIS.
