Ophthalmology Research: An International Journal. 2022 Oct; 17(4): 30-502321–7227http://imsear.searo.who.int/handle/123456789/218431Problem: Bird migration (eye): Georeferencing procedure with clues, rules, functionalities, and restrictions, for avian navigation and nest nidification.Literature Knowledge: Computer vision (sensor): Robot self-referencing with the Perspective-n- Point pose estimation technique.Aim: Hypothesis introduction and proving (“The birds also follow the same georeferencing procedure like robots in avian navigation and nest nidification”).Methodology: (a) Reference data, images, and photography acquisition and 4-means layering (eBird dataset, Flickr imagery, CORINE land covering, and Volunteered Geographic Information);(b) Image processing; and (c) GIS spatial overlay analysis.Results: Statistical spatial analysis using data of the GIS overlays (the 4 layers). Correlation matrix (Avian navigation and nest nidification in low-density urban areas as these are affected by spatial linear geometries and land cover types).Conclusion: A statistically satisfactory approach to the introduced hypothesis.Potential Applications: Human spatial cognition and movement behavior; Children’s motor control and coordination.Birds visual avian navigationbirds nest nidificationspatial linear geometriesgeoreferencingGIS spatial overlayJournal ArticleIndiaDepartment of Forest and Natural Environment Sciences, The International Hellenic University, Thessaloniki, Greece.
