Far away, she is also in front of her.
Depict the true face of the country.
Watch the vicissitudes of time.
Periodic observation of the polar eye from afar.
Reach a wide range and data is objective.
Speaking of which, everyone must have guessed who the surname of "Far Away She" is, she is the famous remote sensing satellite. With the rapid development of China's aerospace industry, industrial incentive policies have been implemented one after another and space-based supply-side capabilities have been improved, and a large number of satellite remote sensing data resources have been accumulated. At present, the demand for satellite remote sensing data services in China is blowing out, which makes the commercial application of remote sensing satellites show a vigorous trend. But what exactly can remote sensing satellites do?What value does it bring to people?Maybe it's not very clear to everyone.
Remote sensing satellites overlook everything at an altitude of seven or eight hundred kilometers above the ground, sense and collect electromagnetic waves radiated or reflected by ground objects and the environment, Jiahe technology will preprocess such data and combine it with geographic data and actual scenes, and finally produce visual charts that people can understand and use, which can be roughly divided into the following categories according to current needs:
01 Land use monitoring
Through the interpretation of high-resolution satellite remote sensing images, Jiahe can realize the distribution monitoring and area statistics of more than 10 types of ground features such as cultivated land, forest land, grassland, wetland, water body, bare land, and glaciers.
According to the characteristics of field morphology, tillage direction, row spacing, ridge spacing and image texture, Jiahe has achieved automatic high-precision extraction of field boundaries, and analyzes and classifies them, automatically divides them and calculates the plot area. There are also scenario applications such as the identification and monitoring of illegal buildings, and the monitoring of non-food and non-agricultural chemicals.
02 Agricultural monitoring and early warning
Jiahe considered the phenology and planting structure information of different regions to make training samples, and constructed a crop classification model with deep Xi. The model can automatically classify and extract the main food crops and cash crops and economic forests with high precision. The accuracy correction module is also added to the model, which further improves the accuracy of the monitoring results through checksum optimization.
In addition, according to the needs of users, crops can also be monitored for growth, seedlings, yield estimation, soil moisture monitoring, early warning of pests and diseases, identification and monitoring of facility agriculture, etc., to help agricultural-related enterprises use big data for agricultural guidance, and provide scientific basis for agricultural production and management.
03 Meteorological monitoring and early warning
Using multi-sensor, multi-satellite and multi-algorithm data inversion, Jiahe can obtain higher precision precipitation data, air temperature data, ground temperature data, air relative humidity, etc.
We collected and analysed historical data on climate indicators such as rainfall and temperature in different regions to identify drought-prone warning areas. At the same time, according to the water demand of the main crops during the growth period, an agricultural drought index evaluation model is established, which can dynamically calculate the drought index at different time nodes. Depending on the size of the index, we set appropriate hierarchical thresholds to map the index values to different agricultural drought risk levels. On the basis of determining the risk level, the model can determine the regional scope and distribution of the corresponding level of drought. This approach enables dynamic, granular drought risk assessment and early warning.
04 Disaster early warning assessment
By comparing images over different time periods, it is possible to monitor crop yield reductions or losses after a disaster, and take timely measures to remediate or adjust agricultural policies.
Jiahe has realized the calculation of floods, high temperature and drought, frost damage, hail, lodging and other algorithms, established a disaster monitoring model based on remote sensing images, determined the scope and degree of disaster, and compared and analyzed with historical disaster data, so as to carry out early warning of disaster degree in time.
In addition, Jiahe also has rich practical experience and cases in specific scenarios such as forest fires and pine caterpillar pests and diseases.
05 Ecological and environmental protection monitoring
By identifying different features such as mountains, woodlands, grasslands, lakes, rivers, farmlands, and sandy lands, Jiahe formed a map of the distribution of ecological resources of mountains, rivers, forests, fields, lakes, grasslands, and sands. In addition, it can also realize vegetation coverage monitoring, forest vegetation ecological index monitoring, air clarity index monitoring, urban heat island monitoring, pollutant gas monitoring, aerosol and haze monitoring, etc., to provide data services for ecological environment monitoring in the target area.
06 Water conservancy monitoringRegularly monitor and obtain data on the spatial distribution, area, density and other data of water resources such as rivers and lakes through remote sensing technology, so as to facilitate water resources surveysIt can also realize water quality monitoring, soil and water conservation monitoring, irrigation area monitoring, etc.
Jiahe can provide a variety of index data to characterize water quality, including but not limited to chlorophyll a content, suspended solids concentration, water transparency, etc., comprehensively analyze various water quality parameters, realize quasi-real-time and macroscopic monitoring of water eutrophication, and realize automatic inversion algorithms for some water quality parameters.
07 Mine supervision
The three-dimensional terrain simulation of the mine can provide intuitive and high-precision basic data for the remediation of abandoned mines and the evaluation of ecological restoration benefits, and the satellite remote sensing images are superimposed on the basis of the digital terrain model to realize the three-dimensional display of the topography of the mine restoration area, and the ecological index monitoring and restoration evaluation of the mining area are carried out according to the ecological restoration benefit evaluation index RSEI (remote sensing ecological index integrating four ecological factors, including greenness component, humidity component, dryness component and heat component).
On the supply side, remote sensing satellite data can be used in many of the above fields, so on the demand side, do you really see the value of these data and successfully achieve commercialization?The answer is yes.
According to the "2022-2028 China Commercial Remote Sensing Satellite Industry Market Panorama Survey and Investment Prospect** Report" released by Zhiyan Consulting, "the market size of China's remote sensing satellite industry in 2021 will be 1181.2 billion yuan. Among them, the market size of data fees is 202.1 billion yuan, and the application market size is 658.8 billion yuan, accounting for nearly 73%. ”
From the field to urban governance, from finance to agricultural insurance, from post-disaster assessment to risk reduction, remote sensing satellite data has exploded into unprecedented social and commercial value in the fields of agriculture, finance and supervision.
Jiahe has been deeply involved in the satellite remote sensing industry for more than ten years, keenly aware of industry trends, accurately positioning the value of the flashpoint, focusing on the demand pain points of government and enterprise units in the agriculture and insurance industries, and has created two industry application standard products for ten years: Diandiantian and Agricultural Insurance.
Towards agriculture and rural revitalizationDiandiantian is an Internet + agricultural service product for farm management, agricultural clue acquisition and decision-making, through which it connects farmers, agricultural production and operation entities, agricultural enterprises and enterprises, and opens up the "last mile" of agricultural information services. All data is displayed synchronously on the mobile terminal and the PC terminal, covering agricultural planting management, business opportunity acquisition, data information services, industrial informatization upgrading, regulatory decision-making, etc.
Jiahe has extended more abundant solutions in scenarios such as high-standard farmland, non-agricultural and non-grain farming, grain subsidy supervision, digital industrial parks, and special agricultural products, and has implemented benchmark cases across the country to empower smart agriculture and help rural revitalization.
Risk Reduction and Empowerment of Agricultural Insurance
The Agricultural Insurance Connect has built an integrated and whole-process service model of "sky and ground", providing full-cycle and full-scenario application services from underwriting to claims. It can be flexibly divided into APP, PC and large screen according to application scenarios and user roles, and is committed to improving the core business goal of "accurate underwriting and rapid claim settlement" of agricultural insurance. 
In addition, Jiahe has strengthened R&D efforts to help insurance institutions use scientific and technological means to promote risk reduction and disaster prevention and mitigation, realize dynamic monitoring of the whole life cycle of insured crops, draw risk maps for key areas to provide decision-making basis for the formulation of rates, and carry out risk early warning for meteorology and pests and diseases, so as to help insurance institutions achieve digital transformation and high-quality development.
