Agriculture and its benefits are numerous and with the advancement in technology there are several tools and methods that can enhance the methods of agriculture. Scientists have been using satellite remote sensing technology or maps with the aim to improve water balance and farming yield appraisal on a large geographical scale throughout the world. Therefore with the availability of several high resolution maps and satellite sensors, the current sensing algorithms being utilized have become so reliable and accurate that it provides detailed crop information for precise agriculture management to improve crop health and production.
Managing agricultural resources
According to the data collected by FOA, nearly 70 percent of freshwater resources is used for agricultural production. Therefore with the global population continuing to grow at a high rate, it is necessary to optimize the right use of water resources and yet increase agriculture production. The agricultural resources are however the most renewable and dynamic natural resources. Therefore reliable, comprehensive and timely information on the agricultural resources is very necessary for countries who’s main economy lies in agriculture. There are agriculture surveys conducted throughout the nation to gather information and the statistic on crops, livestock and rangeland including other agriculture resources with the help of these satellite remote sensing technology and maps.
Real time monitoring and live analysis
Satellite images through these maps can show variations in organic matter and the drainage patterns. The soil higher in organic matter can easily be differentiated from the lighter soil which has lower organic content. Therefore maps and the satellite image date has the potential to provide real time or live analysis for large areas of attributes of growing crops which can help in making timely management decisions which affect the outcome of the current crop, based on the water and fertility of the field. The technology is so advanced that the satellite images and maps can even import graphics or fields of the agricultural land to offer better crop management. These maps can even create custom regions that can show what crop has been currently planted in the region. Having the map for your own agricultural land lets you add additional details as well to show your farming information such as the target harvest time or the last time or next date to apply insecticide.
Moreover the satellite imagery maps analysis for agriculture management and production also allows for:
- Quantitative green vegetation assessment
- Accurate and fast overview
- Tree grading
- Underlying soil characteristics
Enhance decision making through maps
This remote sensing satellite imaging and maps is however an evolving technology with the potential to contribute to studies specific to land cover and change detection just by globally making comprehensive evaluations of several human and environmental actions as possible. These changes would thereby influence policy and management decision making. The maps and satellite image date also enables direct observation of the land surface at repetitive intervals and so lets mapping of the extent and assessment and monitoring of storm water runoff, crop health, air quality, change detection environmental analysis, irrigated landscape mapping, energy savings, yield determination, carbon storage and avoidance and soil an fertility analysis.
