Using Unmanned Aerial Systems (UAS) and Object-Based Image Analysis (OBIA) for Measuring Plant-Soil Feedback Effects on Crop Productivity [PDF]

open access: yesDrones, 2019
Unmanned aerial system (UAS) acquired high-resolution optical imagery and object-based image analysis (OBIA) techniques have the potential to provide spatial crop productivity information. In general, plant-soil feedback (PSF) field studies are time-consuming and laborious which constrain the scale at which these studies can be performed.

Object Based Image Analysis (OBIA) and Data Mining (DM) in Landsat time series for mapping soybean in intensive agricultural regions

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Soya is a widely grown crop in many countries worldwide, being United States, Brazil, Argentina and China the major producers. In Brazil, in the last three decades an explosive growth in production has occurred, nearly thirty times, causing a chain of unprecedent changes of land uses and land cover (LULC) in the territory.

KLASIFIKASI KERUSAKAN JALAN RAYA BERBASIS CITRA UDARA MENGGUNAKAN OBJECT-BASED IMAGE-ANALYSIS (OBIA)

PROSIDING SEMINAR NASIONAL FISIKA (E-JOURNAL) SNF2016 UNJ
Abstrak Kerusakan jalan merupakan masalah serius yang dapat menyebabkan kemacetan, kecelakaan, dan risiko keselamatan. Pada makalah ini, diusulkan penggunaan citra drone untuk mengidentifikasi kerusakan jalan raya. Pendekatan pixel-to-pixel pada citra drone yang beresolusi spasial tinggi sulit dilakukan karena kerusakan jalan menyebar ke beberapa ...

Burn severity estimation using GeoEye imagery, object-based image analysis (OBIA), and Composite Burn Index (CBI) measurements

SPIE Proceedings, 2015
Forest fires greatly influence the stability and functions of the forest ecosystems. The ever increasing need for accurate and detailed information regarding post-fire effects (burn severity) has led to several studies on the matter. In this study the combined use of Very High Resolution (VHR) satellite data (GeoEye), Objectbased image analysis (OBIA ...
