Geospatial is based on data collection, processing, storage and display. We summarize the essence of geoinformatics based on these 4 units.
Presentation of aerial photogrammetry basics, drone route planning software (with mission types) and drone flight planning.
Summary of the principles of computer image processing: color vision (human and machine), color coding and additive color mixing.
The encounter of the theory and practice of 3D modeling: 3D model creation from digital photos, software recommendation and post-processing.
Introducing step-by-step geospatial volume calculation of point cloud and plane; point clouds; DEM and plane; and DEMs.
The three basic pillars of ground photogrammetry survey: basic photography concepts, exposure, photography plan.
Demonstration of GIS-based area selecting, viewshed function and workflow automation, based on DEM generated with UAV data collection.
Background of the photogrammetry method: principles, limits, groups, output files (maps, 3D models) and areas of application.
Geographical Information System (GIS) surface analysis of DEM map files captured by drone surveys in the field of agriculture.
General presentation of GPS, GNSS, RTK, PPK positioning methods and their advantages and disadvantages in the field of aerial photogrammetry.
Demonstration of map creation in QGIS. This article shows You how to edit and style slope and contour maps from a DEM file.
Sharing geospatial data is a difficult task due to increasing file sizes and special formats. What is the future of GIS-based data sharing?
Geospatial data can be a map or a 3D model from drone photogrammetry, a LiDAR survey, GIS and CAD vector and raster data.
Presentation of a GIS-based building motion study calculated by distance measurement from photogrammetric and LiDAR point cloud surveys.
Demonstration of terrain awareness photogrammetry mapping using drone (UAS), in 5 simple steps. The results are accurate maps and 3D models.
