A Hybrid Approach for Land Use/Land Cover Classification

open access: yesGIScience & Remote Sensing, 2009
Atlanta has continuously changed its physical landscape as well as its socioeconomic appearance over the past decades. A hybrid image processing approach, which integrated unsupervised, supervised, and spectral mixture analysis (SMA) classification methods, was used to identify urban land use/land cover changes over a decade (from 1990 to 2000) in the ...

Evolution of Prime Editing: Enhancing Efficiency and Expanding Capacity

open access: yesAdvanced Science, EarlyView.
Most rare diseases are caused by genetic mutations. Prime editing (PE) has emerged as a versatile tool capable of inducing diverse mutations without generating DNA double‐strand breaks. Despite its significant clinical potential, PE faces limitations in terms of efficiency and scalability.

Decision Tree Algorithms for Developing Rulesets for Object-Based Land Cover Classification

open access: yesISPRS International Journal of Geo-Information, 2020
Decision tree (DT) algorithms are important non-parametric tools used for land cover classification. While different DTs have been applied to Landsat land cover classification, their individual classification accuracies and performance have not been ...

Temperature and Farm Labor in Nigeria

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We estimate the impact of temperature shocks on the composition of farm labor in rural Nigeria using a nationally representative household panel survey. Leveraging plausibly exogenous year‐to‐year variation in growing season temperatures, we find that warmer temperatures significantly alter farm labor composition, prompting a substantial shift

Ayer Hitam Forest (AHFR) from space using satellite remote sensing [PDF]

open access: yes, 1999
There is a high demand to map and monitor the land use and assess their condition for ecological and economic reasons. Information on existing land and cover and their spatial distribution is a pre-requisite for any planning, development and management ...
