行业概览 · 水质与环境治理

覆盖整个流域的水质筛查。

选择一个湖泊、水库或排放渠道,即可获得蓝藻色素、泥沙浊度、铁质包膜,或尾矿坝坡上的湿润地面。

What people bring us, and how we handle it.

蓝藻与无害绿藻的区分

在内陆水库,宽波段 NDVI 无法区分两者,所有水华从轨道看都一个样。

窄波段色素读数将蓝藻与普通绿藻分开,有毒水华得以被如实标记。

沿下游追踪酸性排水

抓样监测只能给出点位。大流域内的面源径流会从点位之间漏掉。

亚米级短波红外沿河道底部填绘次生铁与硫酸盐包膜,以单一三价铁类别而非具体矿物名称报告。

尾矿坝坡上的渗漏

目视巡检往往在坝体开始滑塌之后才发现渗水。

跨期短波红外水分深度可标记下游坝坡持续湿润的地面。让 Lisaris 在每次新场景落地时重跑该对比。警报始终仅作参考。

WORKED EXAMPLE

Case study: 伊利湖蓝藻与浊度筛查

覆盖伊利湖西部湖盆的蓝藻色素与泥沙羽流生物光学筛查。

01

先过产品级别门限,再除耀斑

Product level gate, then glint and adjacency handling

只接受离水反射率产品。陆地校正产品用在水面上会返回看似合理却错误的数值,因此被直接拒绝。

02

藻蓝蛋白基线扣除

Phycocyanin height separated from chlorophyll-a

窄波段基线扣除给出色素吸收的高度。不反演细胞密度。

03

水体时间序列

One point per acquisition, gaps left visible

每次采集一个点,按地面时间排序,缺口保持可见而不是被填补。

04

您将获得

COG raster with the published fit named in its provenance

标明每个图层所依据已发表拟合方法的筛查栅格。

FREQUENTLY ASKED QUESTIONS

Questions we get asked about this sector.

不能。光学传感器测量的是颗粒物、色素和矿物包膜的吸收与散射。砷、铅等溶解态痕量金属没有直接的光学吸收特征,因此任何分辨率的传感器都无法从太空测量它们。
