Sensor Products

EO time series observations, e.g. BOA images, often comes with other (auxilliary) files, e.g.
(taken from FORCE docs):

Product	Description
BOA	Bottom-of-Atmosphere Reflectance
TOA	Top-of-Atmosphere Reflectance
QAI	Quality Assurance Information
AOD	Aerosol Optical Depth
DST	Cloud / Cloud shadow /Snow distance
WVP	Water vapor
VZN	View zenith
HOT	Haze Optimized Transformation

Let the BOA be the "core" product of the time-series source. It is reuqested to allow each core product to be accompanied by auxilliary products, here "TOA", "QAI" etc.

Implementation ideas:

Data Model:

• each SensorInstrument instance defines a "core" product and, optionally, multiple "auxilliary" products
• aux rasters need to match the core raster in: samples, lines, pixel size, spatial extent and CRS
• aux rasters can differe in number of bands
• each Time Series Source defines:
  • a core raster source
  • a list of optional aux raster sources
  • during loading only thos aux rasters are loaded, which are predefined in the EOTSV settings

Visualization

Enhance the Map View layer tree by showing each sensor type as group node and core and aux sources in child nodes:

Change it from now

<Map View>
    <Sensor Layer "Landsat">
    <Sensor Layer "Sentinel">

to:

< Map View>
   < Sensor Layer Group "Landsat">
      < Core Layer "BOA">
      < Aux Layer "QAI">
      < Aux Layer "QAI">
   < Sensor Layer Group "Sentinel">
      < Core Layer "BOA">
      < Aux Layer "TOA>

Layers below a Sensor Layer group should be arrangable in a flexible way:

• change to order of core and aux layers, e.g. to show a mask on top of a BOA image or the other way.
• add other QgsMapLayers e.g. a vector layer that is imposed only on MapCanvas that show "Sentinel" data.
