Course Description

Proper geocoding of Aerial Imagery can be challenging. Aerial Imagery follows the pin-hole camera model where all light beams are passing through a single point. By taking also into account the relief of the targeted area, the resulting dataset has a location-based scale, rendering the usual polynomial transformations available via the common GIS software (e.g. 1st, 2nd, and 3rd order) not appropriate for the task.

To perform the orthorectification of a single aerial imagery one needs the following:

  • camera’s focal length
  • digital elevation model (DTM for orthorectified, DSM for true-ortho)
  • coordinates of camera fiducial points (for historical aerial images)
  • Ground Control Points i.e. image points with known 3d coordinates (X, Y, h)

To this end, this course provides the user with a quick introduction to which is a web-based platform providing the tools to perform the Orthorectification process. The output is compatible with all OGC-compliant GIS software and CAD systems capable of handling GeoTiff files.

About your Instructor

Dr Argyros Argyridis is a Rural & Surveying Engineer. He received both, his Dipl-Ing and PhD from the NTUA. His expertise covers the spectrum of Geographic Information Sciences, Remote Sensing, Earth Observation, and EU/Copernicus technologies. He is the author of 10+ publications in scientific journals, conference proceedings. His research, science, and technology interests include the investigation, implementation and integration of image analysis, machine learning, Geomatics/GIS, and knowledge representation methodologies, towards automation of mapping from Remotely Sensed data, along with the design and development of web-based Geoplatforms. His programming skills include multiple languages (e.g., C/C++, PHP, Python, SQL, JavaScript etc), along with relevant libraries and software for image analysis (Orfeo Toolbox, OpenCV, al ArcGIS technologies, ERDAS Imagine) machine learning (e.g. Tensorflow, Caffe), data management (e.g., PostgreSQL, MySQL, MSSQL Server, data exchange protocols, WMS/WFS, JSON/GeoJSON, SOAP, Rest Services), and Geoplatform development (OpenLayers, Leaflet, ArcGIS Server, ArcGIS Geoportal, and ESRI technologies). His management skills include timely coordination of projects, proper management and allocation of human resources, significant communication skills, and budgeting.
