Emerging technologies with dendrochronology: platforms, progress, and potential
Ultra high resolution imaging is becoming standard across the sciences and must be a priority for dendrochronology. Large format scanners fail to resolve micro rings and the anatomical structures of increasing scientific interest. Meanwhile, current software limitations include cost, user experience, data management flexibility, and capacity for handling large file sizes. We argue for a new paradigm and present a technology framework that integrates gigapixel macro photography, a cloud-hosted digital asset management system, and an internet accessible toolbox that facilitates rapid measurement, dating, and annotation on tree ring imagery.
Further integration of emerging technologies will transform throughput capacity for dendro data development. Toward the end of automated quantitative wood anatomy, recent computer vision results with machine learning are encouraging. The most urgent priority is to develop an affordable platform for gigapixel image acquisition.
