The Terra Populus project (TerraPop) addresses a variety of data management, curation, and preservation challenges with respect to spatiotemporal population environmental data. In this article, we describe our approaches these challenges, particular focus on geospatial workflows associated provenance metadata. goal TerraPop is enable research, learning, policy analysis by providing integrated describing people their environment. To do so, assembling globe-spanning temporally extensive...
The U.S. Census Bureau plans to use a new disclosure avoidance technique based on differential privacy protect respondent confidentiality for the 2020 Decennial of Population and Housing.Their injects noise number parameters into published statistics.While injection does confidentiality, it achieves protection at cost less accurate data.To better understand impact that has accuracy, we compare data from complete-count 1940 with multiple differentially private versions same set.We examine...
Abstract The first version of the Integrated Public Use Microdata Series (IPUMS) was released to users in 1993, and since that time IPUMS has come stand for interoperable accessible census survey data. Initially created harmonize U.S. microdata over time, now includes from international censuses surveys on health, employment, other topics. also provides geo-spatial data, aggregate population environmental supports ten data products, each disseminating an integrated collection with a set...
Abstract Many geoscience disciplines utilize complex computational models for advancing understanding and sustainable management of Earth systems. Executing such their associated data preprocessing postprocessing routines can be challenging a number reasons including (1) accessing the large volume variety required by model, (2) collections generated (3) orchestrating processing tools, each with unique software dependencies, into workflows that easily reproduced reused. To address these...
Terra Populus, part of National Science Foundation's DataNet initiative, is developing organizational and technical infrastructure to integrate, preserve, disseminate data describing changes in the human population environment over time. A large number high-quality environmental datasets are available, but they widely dispersed, have incompatible or inadequate metadata, geographic identifiers. The new Populus enables researchers identify merge from heterogeneous sources study relationships...
Terra Populus, or TerraPop, is a cyberinfrastructure project that integrates, preserves, and disseminates massive data collections describing characteristics of the human population environment over last six decades. TerraPop has made number GIScience advances in handling big spatial to make information interoperable between formats across scientific communities. In this paper, we describe challenges these data, 'deserts deluge' are common more broadly, explore computational solutions...
This article presents a valuable summary and comparison of the major gridded population data products currently available.While datasets discussed are generally well-established have each been individually described in previous publications, having comparing key properties these one place will be very useful for researchers trying to determine which product is best suited their particular application.Furthermore, concept "fitness use" helpful approach this context.Each incorporates different...
