纳米比亚的卫星中心警告灾难威胁

[Windhoek]纳米比亚的新卫星数据中心将帮助农民做准备干旱, floods, bushfires and pests.

地球观察和卫星应用研究与培训中心（EOSA-RTC）于本月（7月6日）与非洲对可持续发展环境的监测（AMESD）合作推出。beplay足球体育的微博它位于纳米比亚的理工学院，包括卫星data receiving station and data centre, which will provide data useful for agriculture.

这些数据将免费提供给农民协会和政府部门，包括水指数，降雨估算和土壤水分含量的地图。

Reliable data is essential to preparing for自然灾害。今年早些时候，纳米比亚受到创纪录的洪水袭击，尽管降雨通常很少。Wildfires are expected to wreak havoc in the current dry season.

“降雨对纳米比亚很重要。基于错误信息的错误可能是昂贵的。对于生存农民来说，这可能是食物或不食物之间的区别。”

"We will use the satellite to detect and map unknown smallwaterbodies. We will also store ‘normalised different vegetation indices’ [measure of vegetation on the ground] and then further process them into a variety of value-added products — these we will make available with extra text to help people to understand and interpret the information," said Coetzee.

Not all vegetation has leaves so even if it looks green it does not mean there is no problem. Remote sensing, therefore, serves as anearly warning system for a failed harvest, said Celeste Esbach, researcher at the polytechnic.

Coetzee补充说：“我们可以预测问题在野火方面出现的地方家畜，缺水或农作物的生存能力”。

Namibian researchers have already been assessing raw data obtained directly from satellites. But the new centre will now provide specific, useful indices coming from that data, making interpretation easier.

The centre receives low- and medium-resolution satellite images from the international data service, Eumetcast, which disseminates meteorological data, from a variety of satellites, such as the赤道上方的MeteoSat卫星。

From next month Namibia will be linked to the AMESD programme that circulates a range of geographic data and maps relating to crops, droughts and wildfires to Southern African Development Community (SADC) countries.

国家遥感中心负责人约翰·勒鲁克斯（Johan Le Roux）表示，他们现在将从中心获取处理过的信息，而不是直接依靠卫星，从而更容易使用遥感软件和产品。

The polytechnic also cooperates with the Cape Peninsula University of Technology (CPUT) in South Africa on research, building small satellites, and designing applications for satellite imagery.
