Georeferencing of Multi-Channel GPR - Accuracy and Efficiency of Mapping of Underground Utility Networks

Remote Sensing, 2020
Due to the capabilities of non-destructive testing of inaccessible objects, GPR (Ground Penetrating Radar) is used in geology, archeology, forensics and increasingly also in engineering tasks.

Abundance and reproduction behavior data for waterbirds (Anatidae, Rallidae, Charadriiforms, Podicipediforms) breeding in European France based on a probability sampling design

Ecological Research, EarlyView.
In this paper, we provide the dataset issued from field surveys of 2428 grid cells of 500 m × 500 m in French wetlands during springs 2021 and 2022. Such cells resulted from a stratified two‐stage sampling design. The 132,292 birds recorded in this study, together with their reproduction behavior, will be used to evaluate national breeding population ...

Georeferencing and data quality: SANBI’s story [PDF]

Biodiversity Information Science and Standards, 2018
Georeferencing helps to fill in biodiversity information gaps, allowing biodiversity data to be represented spatially to allow for valuable assessments to be conducted. The South African National Biodiversity Institute has embarked on a number of projects that have required the georeferencing of biodiversity data to assist in assessments for redlisting

Aplicabilidade do georreferenciamento de aerofotos de pequeno formato na formação de bancos de dados espaciais: uma alternativa para o cadastro técnico rural municipal Suitability of georeferencing of aerial photography of small format in the formation of data bank: an alternative to rural municipal technical cadaster

Ciência Rural, 1997
A falta de base cartográfica adequada para certas regiões, tem levado a um uso mais intensivo de aerofotos de pequeno formato como fonte de informação espacial ágil e de baixo custo aos usuários de sistemas que tratam imagens georreferenciadas para ...

Quality issues in georeferencing: From physical collections to digital data repositories for ecological research

Diversity and Distributions: A journal of biological invasions and biodiversity, 2020
Natural history collections constitute an enormous wealth of information of Life on Earth. It is estimated that over 2 billion specimens are preserved at institutions worldwide, of which less than 10% are accessible via biodiversity data aggregators such

The artisanal underground: gold, subsistence, and subsurface materiality in Colombia

Journal of the Royal Anthropological Institute, EarlyView.
Abstract This article focuses on subsurface materiality to explore how small‐scale gold miners in Colombia navigate formal politics. In much critical research, the underground appears as a space of great developmentalist ambition, whose resources enable corporate expansion and bureaucratic rule.

Development of Systematic Image Preprocessing of LAPAN-A3/IPB Multispectral Images [PDF]

International Journal of Advanced Studies in Computer Science and Engineering (IJASCSE), Volume 7 Issue 10, 2018, 2019
As of any other satellite images, LAPAN-A3/IPB multispectral images suffered from both geometric and radiometric distortions which need to be corrected. LAPAN as satellite owner has developed image preprocessing algorithm to process raw image into systematically corrected image. This research aims to evaluate the performance of the developed algorithm,

An Initial Seed Selection Algorithm for K-means Clustering of Georeferenced Data to Improve Replicability of Cluster Assignments for Mapping Application [PDF]

, 2016
K-means is one of the most widely used clustering algorithms in various disciplines, especially for large datasets. However the method is known to be highly sensitive to initial seed selection of cluster centers. K-means++ has been proposed to overcome this problem and has been shown to have better accuracy and computational efficiency than k-means. In
