XST-VINet Fully automated vegetation index meter
offeringssummarize
The XST-VINet fully automatic vegetation index meter produced by Beijing StarView Technology Co., Ltd. consists of several sub-nodes and convergence nodes with 6 spectral absorption channels on the upper and lower sides, and it is a networked vegetation index monitoring instrument based on the architecture of Internet of Things (IoT). It is capable of automatic monitoring by multi-node wireless networking, obtaining long time series of vegetation index, and uploading the aggregated data to the server in a unified way.
Based on self-developed algorithms, it records raw data and automatically calculates multiple vegetation indices:
Normalized Difference Vegetation Index (NDVI)
Enhanced Vegetation , Index (EVI)
Ratio Vegetation Index (RVI)
Difference Vegetation Index (DVI)
Atmospherically Resistant Vegetation Index (ARVI)
Features
Flexible deployment: sub-nodes with long-life lithium batteries, completely wireless self-organizing network
High stability: all-round IP66 protection, strong anti-interference ability, high precision, low power consumption
Data Security: Triple Backup for Node Local, Aggregation Node and Wireless Transmission
Application Areas
It is applied to the monitoring of vegetation growth, estimation of vegetation biomass and authenticity check of remote sensing products in the field of agriculture, forestry and ecological research.
