Set of controls for satellite images and some vector products generated from them.

These scripts were developed in order to assist the control of raster and vector data result of the project "Proyecto de producción y control de Ortoimágenes, Modelos Digitales de Elevación y Cartografía", carry by IDE (1).

IDE is the Uruguayan national agency that establishes public standards for global access and the exchange of geographic information in Uruguay.

The project produced and certified digital ortho-images of all national coverage, digital terrain models and basic cartography at a scale of 1: 10,000.

> python imagery_controls.py $input_folder $output_folder --control $control  --conform $conform_value --deviation $deviation_value

Control = { pixel_size, dig_level, bands_len, rad_balance, nodata, aall }

The $input_folder can be recursive explored adding the option --recursive. By default, this option is False (--non-recursive).

Help can be display with option -h.

Analize that every .tif file of a directory complies with a stablish spatial resolution given by the pixel size.

If the program is executed with the option --twf, then if found, .twf files will be used first.

Analize that every .tif file of a directory complies with a stablished digital level given by the datatype of the bands.

Analize that every .tif file of a directory complies with a stablish spectral resolution given by the number of bands.

Analize that every .tif file of a directory complies with a stablished radiometric balance given by the percentage of pixels in the extremes values.

Analize that every .tif file of a directory complies with a stablished percentage of NODATA pixels.

> python postgis_controls.py $dbname $dbschema $user $password $output_folder --control $control --host $host --port $port --summary $summary

Rule = { invalid, duplicate, multipart, intersect, null, aall }

The $input_folder can be recursive explored adding the option --recursive. By default, this option is False (--non-recursive).

Help can be display with option -h.

Search invalid geometries of all tables in a given schema. Uses ST_Invalid PostGIS for the task function.

Search duplicate geometries of all tables in a given schema.

Search multipart geometries of all tables in a given schema.

Search not allowed intersection between geometries of all tables in a given schema. Allowed intersections are taken from a json file passed with the option --admissibles path\to\admissibles.json.

The admissibles file has the following format,

{
  "table_i1": ["table_j1", .., "table_k1"],
  "table_i2": ["table_j2", .., "table_k2"],
  ..,
  "table_iN": ["table_jN", .., "table_kN"]
}

where 1 <= i,j,k <= N.

Search null geometries of all tables in a given schema.
