prospect v1.6.0

Released version of the software with the latest changes from the review

prospect v1.5.1

version following reviews for publication in JOSS

addition

  • added a function download_LeafDB to get leaf databases from gitlab repository

prospect v1.5.0

version following reviews for publication in JOSS

Changes

  • change license to MIT (Issue#3: Consider a different license)
  • include plain text version of specific absorption coefficients with variable prospect::SpecPROSPECT_FullRange (Issue#4: Consider including plain-text versions of PROSPECT coefficients)
  • remove function plotinv and corresponding required packages (Issue#5: Move randomcoloR to Suggests)
  • pre-calculate calctav for angles 40 degrees (default) and 90 degrees (always needed) and add them to SpecPROSPECT_FullRange (Issue#6: Pre-calculate calctav)
  • added tests for PROSPECT, Invert_PROSPECT and Invert_PROSPECT_OPT (Issue#7: Add automated unit tests)
  • add CONTRIBUTION.md and CODE_OF_CONDUCT.md (Issue#8: Add contribution guide)
  • update documentation and harmonize with corresponding code for JOSS manuscript (Issue#10: harmonize web tutorial with JOSS manuscript examples)

  • only two versions now defined in the package (D and PRO), and the use of brown pigments is accessible during inversion by setting Est_Brown_Pigments == TRUE

fixes

  • fixed error occuring when PROSPECT-PRO inversion performed to assess EWT

prospect v1.4.0

fixes

deal with default values when seting proteins, CBC and LMA to non constant value

prospect v1.3.0

new release including JOSS draft

prospect v1.2.7

fixes

  • removed reference to multiprocess, multisession used exclusively from future

prospect v1.2.6

fixes

fixed issue raised by morelju on 2023/05/31 --> bug when running prospect with default parameterization because NULL value included in dataframe LRT_default <- PROSPECT(SpecPROSPECT) Now runs

prospect v1.2.5

addition

  • added function plotinv to produce scatteerplots between measured and estimated values

prospect v1.2.3

Fixes

  • Fixed bug initial inversion outputs NA

prospect v1.2.2

Fixes

  • added default xlub which are not specified by user, and result in an error

  • changed lambda to Sublambda in Invert_PROSPECT_OPT

Fixes

  • Added library NlcOptim in function tryInversion
  • fixed bug confusing CBC with proteins when performing optimal spectral domain inversion
  • fixed input parameters for FitSpectralData: added UL_Bounds=TRUE to specify that UserDomain corresponds to upper and lower boundaries, not explicit definition of spectral bands

prospect v1.0.1

Changes

  • Added NEWS.md

Fixes

  • Fixed bug occuring when only reflectance or only transmittance defined
  • Fixed case when input data for inversion is not 1 nm sampling

prospect v1.0.0

First public release in Gitlab

The package prospect includes the PROSPECT leaf model in its two recent versions: PROSPECT-D, accounting for chlorophyll, carotenoids, anthocyanins, equivalent water thickness and leaf mass per area PROSPECT-PRO, accounting for chlorophyll, carotenoids, anthocyanins, equivalent water thickness, proteins and carbon-based constituents

Brown pigments car be included additionally to the other chemical constituents for both versions of the model.

The package also includes methods for the inversion of PROSPECT using leaf optical properties (directional-hemispherical reflectance, directional-hemispherical transmittance, or both) in order to estimate leaf chemistry and structure parameter. These methods are based on iteerative optimization of a merit function minimizing RMSE between measured and estimated leaf optical properties, but custom functions can be implemented by users.

Optimal subdomains and prior N estimation as introduced in recent publications have also been included in the package.
