Grassland Survey

How can hyperspectral imaging help grassland resource mapping?

Grassland health and degradation rating

Using vegetation indices to analyze the health status of grassland plants and assess grassland restoration or degradation rating.

Vegetation distribution in grassland

Collect hyperspectral grassland data, intelligently classify vegetation, and estimate distribution and area.

Digitized spectral base map

Collect low-altitude remote sensing data of grasslands to form a hyperspectral digital grassland base map.

Investigation of artificial structures

Use hyperspectral data to intelligently screen artificial structures and determine the area and distribution of the base map.

Advantages of Hyperspectral Low-altitude Remote Sensing

Efficient collection

Equipped with a drone to collect high-precision spectral data from the ground, greatly improving survey efficiency.

Intelligent classification

Using hyperspectral intelligent classification model to classify different grassland vegetation.

Information-rich

Hyperspectral data has rich bands, which can retain more details of objects compared to conventional multispectral data.

Automatic analysis

Automatic analysis based on band operation provides more objective reference.

Scheme advantages

	High-precision grassland mapping. The DJI M300 RTK can fly within 500 meters to collect spectral data of grasslands at close range, with a resolution of up to 1cm.
	Portable and easy to use. One-stop solution for DJI native remote control path planning, hyperspectral parameter settings, and task control.
	High data quality. It supports the acquisition of high-precision spectral data up to 3400×880, with spectral sampling resolution as low as 0.7 nm.
	Worry-free flight. HSG-1P can be equipped with third-party property insurance, with a guaranteed limit for the entire aircraft, making flying more comfortable.

HSG-1

Post-processing software

Opt Studio

Scheme advantages

	Efficiency is crucial for large-scale grassland mapping. The CW-25E can operate for up to 6 hours per sortie, meeting the needs of large-scale grassland mapping surveys.
	Using Opt Studio, we can conduct large-scale data fusion for grassland and solve the problem of building hyperspectral base maps for grasslands in one step.
	It can take off and land vertically without a runway, which is beneficial for taking off and landing on the undulating terrain of grasslands.
	HSG-1 uses external power supply to obtain power from the drone platform for long-term operation.
