Emir Hartato created an article, What can I do with surface reflectance product?
Surface reflectance product removes atmospheric artifacts which increases the consistency and comparability between images acquired at different times. Thus, this product can be leveraged to normal...

Emir Hartato created an article, Why Planet surface reflectance product uses 6S atmospheric radiative transfer model?
While we understand that there are various atmospheric radiative transfer model out there (see here), Planet uses the 6S model due to a number of reasons: It is easily integrated to Planet platfor...

Emir Hartato created an article, How are atmospheric parameters sourced for the correction to surface reflectance?
As the Dove sensor only records visual and near-infrared spectral bands, it is difficult to measure atmospheric parameters directly from the Dove imagery. As a result, key atmospheric parameters ar...

Emir Hartato created an article, What is Surface Reflectance?
Surface reflectance is the amount of light reflected by the surface of the earth. It is a ratio of surface radiance to surface irradiance, and as such is unitless, and typically has values between ...

Emir Hartato created an article, Any idea if the Surface Reflectance user community can expect similar products for RapidEye?
Surface Reflectance product for RapidEeye images is already available for `REOrthoTile` item under `analytic_sr` asset (Data API) or `analytic_sr` bundle (Orders API).

Emir Hartato created an article, Who are the intended users of Surface Reflectance products?
The immediate stakeholders for these products are agricultural customers, although accurately processed surface reflectance retrievals are useful for change detection and data visualization.

Emir Hartato created an article, How does Surface Reflectance improve on what came before it?
The standard PlanetScope products that are distributed today are radiometrically calibrated (scaled at-sensor radiance) and orthorectified using ground control points for precision correction and d...

Emir Hartato created an article, How is the Surface Reflectance product provided?
The Surface Reflectance product is available through: The Data API as the `analytic_sr` asset under the `PSScene4Band` , `PSOrthoTile`, and `REOrthoTile` items; The Orders API as the `analytic_s...

Emir Hartato created an article, When is the Surface Reflectance product available?
Due to the delay in availability of MODIS near-real time (NRT) aerosol data, it is possible to have an additional latency in the availability of the surface reflectance product w.r.t the TOA scenes...
