MINERVE-D3

Le projet TRAC MINERVE-D3 correspond aux développements informatiques réalisés dans le cadre de la thèse MINERVE d'Alain Foehn.

Un certain nombre d'outils, présentés ci-dessous, ont été développés.
La plupart des outils intéragissent directement avec la base de données MAYA et dans une moindre mesure avec la base de données MINERVE. Les fonctions permettant cette intéraction on été regroupées dans le dossier

MINERVE-D3\Code

Le fichier fc_API-REST.R contient les fonctions suivantes :

download_data_in_slots Download data (value of a pixel or aggregated function) over a period, using function download_slot for each slot.
download_slot Download data (value of a pixel or aggregated function) for a given slot of the entire period.
download_timeseries_from_raster Function used by download_slot for preparing the download request for data of a pixel over the slot, using function download_request.
download_request Function used to download the request text prepared by download_timeseries_from_raster.
acquire_MAYA_data Function used by download_slot for managing the download of raster data using the download_raster function.
download_raster Function used by acquire_MAYA_data for downloading a raster (aggregation function defined in the API-INI file).
download_altitude_of_pixel Function to download the elevation value of a pixel from the metadata DEM of a given product.

Le fichier fc_common.R contient les fonction suivantes :

get_token Manage acquisition of the token : first uses get_token_local, if it fails, uses get_token_server and the saves the token with write_token.
get_token_local Reads the token from the local file.
get_token_server Acquires a new token from the API-REST.
write_token Saves in the local file the newly acquire token.
define_computetime Date formating function
print_elapsed_time Function to print the time of a code part, with an argument for the text to be printed.
pause_and_print Function to makes a break and print that it has done a break (used in the download functions, to handle cases where API-REST does temporary not answer, for example due to a manuel restart).
write.RSMcsv Function to export data in a CSV format readable by RS MINERVE.
