Evaluation of hierarchical self-organising maps for weed mapping using UAS multispectral imagery

Computers and Electronics in Agriculture, 2017
Abstract Remote sensing has been used for species discrimination and for operational weed mapping. In the study presented here, the detection and mapping of Silybum marianum using a hierarchical self-organising map is reported. A multispectral camera (green-red-NIR) mounted on a fixed wing Unmanned Aircraft System (UAS) was used for the acquisition

Weed surveys and weed mapping in Europe: State of the art and future tasks

Crop Protection, 2020
Long-term national European weed surveys, large scale classical phytosociological programs and camera-based documentation systems lead to results which can be documented in form of maps. Comparisons of these visual representations of relative weed positions can be used for the prediction of changing weed spectra and of plant biodiversity changes ...

Academic Map Library Weeding

Bulletin - Association of Canadian Map Libraries and Archives (ACMLA), 2023
While maps remain an important part of library work, there has been a dearth of scholarly discussion on weeding maps. Some authors have offered suggestions in particular contexts – notably in public libraries and U.S. depository libraries. This leaves significant room for further discussion for those outside of the U.S.

Stitching of Video Sequences for Weed Mapping

2015 International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP), 2015
Weeds are among the most significant and costly environmental threats in Australian agriculture. The distribution, size, density and species of weeds are often heterogeneous in cropping lands. Instead of uniformly spray the same type of herbicide to a whole farm land, using weed maps to do selective spray can reduce herbicide usage and therefore can ...

Weed mapping technologies in discerning and managing weed infestation levels of farming systems

Research on Crops, 2020
The advent of robust sensing technologies in remote and proximal sensing systems has led to the generation of accurate weed maps thus enabling precise weed management (PWM). The data from the weed maps are crucial input for crop-weed discriminating algorithms and also decision support models that quantify the risk posed by the weeds on the fields.

Weed Mapping with Co-Kriging Using Soil Properties [PDF]

Precision Agriculture, 1999
Our aim is to build reliable weed maps to control weeds in patches. Weed sampling is time consuming but there are some shortcuts. If an intensively sampled variable (e.g. soil property) can be used to improve estimation of a sparsely sampled variable (e.g. weed distribution), one can reduce weed sampling. The geostatistical estimation method co-kriging

Weed Seedbank Evaluating Method to Generate Spatial Distribution Maps

Journal of Environmental Science and Health, Part B: Pesticides, Food Contaminants, and Agricultural Wastes, 2005
The objective of this work was to develop a fast and practical method of weed seedbank evaluation to generate spatially distributed maps for use in site-specific weed management. Soil cores were collected at 0.20 m depth, air-dried, and then submitted to seedling growth in greenhouse.
