Utilization of third party software (Agisoft PhotoScan) making it easier to acquire and process aerial photogrammetric data. This research also produces 2-dimensional high resolution image data on the research area. This research aims to determine the stage or overview of data retrieval process with DJI Phantom 4 (multi-rotor quad-copter drone) with processing using third party software.

The application of drones in the field of geospatial science today is in great demand because of its relatively easy operation and relatively affordable cost compared to satellite systems especially high-resolution satellite imagery. Nowadays, many photogrammetric mapping methods have used UAV / unmanned drones or drones to retrieve and record data from an object in the earth. Solid Earth, 8(6), p.1241.Aerial photogrammetry is one of the Alternative technologies for more detailed data, real time, fast and cheaper. Rapid, semi-automatic fracture and contact mapping for point clouds, images and geophysical data.

Thiele, S.T., Grose, L., Samsu, A., Micklethwaite, S., Vollgger, S.A. Can anyone recommend a method to introduce virtual 'scanlines' along the platform, to characterise spacing (P10 frequency) of the main joint sets? What I'm interested in now is discontinuity set spacing. These are useful inputs if we want to make a simple 2D DFN, for example. It's very straightforward to use the field calculator in QGIS to query trend and length of each trace line (image attached). The package makes trace mapping very easy: manually pick out visible endpoints of a discontinuity, and the code uses a least-cost path solver to complete the trace line. Since then, I've been playing with the semi-automatic trace mapping package GeoTrace, implemented in QGIS by Sam Thiele and others at Monash University.

After a short flight with my Mavic Pro drone, I used Agisoft Photoscan to make an orthorectified mosaic of a wave-cut sandstone platform near Coalcliff, NSW.
