, 2023 Geodata discoverability was identified decades ago as a crucial challenge both by the Spatial Data Infrastructure (SDI) community and, for the more general case of data discoverability, by the Web of data community. It has kept growing in the late years and actors beyond SDI and Web of data specialists, from the public or private sector, with different

Genomic structure and ex situ conservation of the North American grapevine Vitis labrusca
PLANTS, PEOPLE, PLANET, EarlyView.The North American wild grapevine species Vitis labrusca is an important source of disease resistance and climate resilience traits for breeding new grapevine cultivars. To ensure its continued use in breeding, V. labrusca must be accurately identified and genetically diverse material must be conserved.

AUGMENTING 3D CITY MODEL COMPONENTS BY GEODATA JOINS TO FACILITATE AD-HOC GEOMETRIC-TOPOLOGICALLY SOUND INTEGRATION [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012 Virtual 3D city models are integrated complex compositions of spatial data of different themes, origin, quality, scale, and dimensions. Within this paper, we address the problem of spatial compatibility of geodata aiming to provide support for ad-hoc ...

Design considerations for breeding waterfowl surveys
Wildlife Society Bulletin, EarlyView.This study evaluated how different survey designs affect the accuracy and precision of breeding waterfowl population estimates in Iowa's Prairie Pothole Region. Using aerial survey data from 2016–2018, we found that conducting at least 2 visits per season reduced bias in pair estimates, particularly for wood ducks and blue‐winged teal, while mallard ...

Estimating National and Foreign Trade Elasticities Using Generalized Transport Costs
Journal of Regional Science, Volume 65, Issue 2, Page 471-496, March 2025.ABSTRACT We introduce the definition of two distinct trade elasticities corresponding to imports from regions located in the same country (national elasticities) and foreign regions located in other countries (foreign elasticities). We resort to a three‐tier nested CES utility structure to derive the corresponding demand gravity equations.

Automated extraction of leaf mass per area from digitized herbarium specimens
New Phytologist, EarlyView.Summary The digitization of vast herbarium collections has made millions of plant specimen images freely available online, which can now be used to generate phenotypic datasets of unprecedented scope. Here, we assess the potential of computer vision tools to automate the extraction of predicted leaf mass per area (LMApred) from digitized herbarium ...

, 2013 The management of massive amounts of geodata collected by sensor networks creates several challenges, including the real-time application of summarization techniques, which should allow the storage of this unbounded volume of georeferenced and timestamped data in a server with a limited memory for any future query. SUMATRA is a summarization technique,
