Full description

A collection of digital outcrop models constructed using unmanned aerial vehicle (UAV) photogrammetry and used to quantify the geometry and distribution of intrusions within the shallow plumbing system of Volcán Taburiente, La Palma (Canary Islands, Spain).

A detailed description and analysis is included in my PhD thesis at:
https://doi.org/10.26180/5dd7263c09ac1

Overview:

Please refer to Dataset_Overview.pdf/pptx for an overview of each of the surveys including descriptions of:

1. their extent and location

2. ground sampling distance

3. features of interest

Point clouds:

The aligned and interpreted point clouds from each survey area have been included as CloudCompare .bin files in _point_clouds_only.zip. CloudCompare can be freely downloaded here: http://www.cloudcompare.org/ and used to (1) view the data and interpretation and (2) export it to other point cloud or raster formats.

Structural measurements:

Measurements of dyke orientation and thickness have been exported from CloudCompare to an easily readable .xml format and stored in _structural_measurements_only.zip. Example code for loading, plotting and analysing these data can be found here: https://github.com/samthiele/pycompass

Complete surveys:

Complete datasets are included in the other .zip files, named according to the area they cover. Each of these includes:

1. UAV images (.jpg)

2. Agisoft Photoscan files

3. LAZ point clouds

4. Orthophoto rasters

5. Digital elevation models

6. aligned and interpreted point clouds (.bin)

Unprocessed Surveys:

UAV images from surveys that were acquired but have not been processed are included in 12_Unprocessed Images.zip.
