Lines of Waters Inland BI020

Vector layer “Lines of Waters Inland BI020” from Argentina’s Instituto Geográfico Nacional, extracted from the official WFS service and published as GeoParquet and PMTiles.

Features: 125
Geometry: MultiLineString
CRS: WGS 84 / EPSG:4326
Source: official IGN WFS service

Direct access

The GeoParquet can be queried over HTTP without downloading the complete dataset:

1INSTALL httpfs; LOAD httpfs;
2SELECT "entidad", "objeto", "fna", "gna", "nam", "fdc"
3FROM read_parquet('https://data.source.coop/nlebovits/ign-argentina/themes/hidrografia-y-costas/aguas-continentales/ign_lineas_de_aguas_continentales_bi020/ign_lineas_de_aguas_continentales_bi020.parquet')
4LIMIT 20;
1INSTALL httpfs; LOAD httpfs;
2SELECT "entidad", "objeto", "fna", "gna", "nam", "fdc"
3FROM read_parquet('https://data.source.coop/nlebovits/ign-argentina/themes/hidrografia-y-costas/aguas-continentales/ign_lineas_de_aguas_continentales_bi020/ign_lineas_de_aguas_continentales_bi020.parquet')
4LIMIT 20;

The fast display representation is the PMTiles asset; use styles/default.json as the default MapLibre style.

Example queries

Most common classes or codes

1INSTALL httpfs; LOAD httpfs;
2SELECT "objeto", count(*) AS entidades
3FROM read_parquet('https://data.source.coop/nlebovits/ign-argentina/themes/hidrografia-y-costas/aguas-continentales/ign_lineas_de_aguas_continentales_bi020/ign_lineas_de_aguas_continentales_bi020.parquet')
4GROUP BY 1
5ORDER BY entidades DESC, 1
6LIMIT 25;
1INSTALL httpfs; LOAD httpfs;
2SELECT "objeto", count(*) AS entidades
3FROM read_parquet('https://data.source.coop/nlebovits/ign-argentina/themes/hidrografia-y-costas/aguas-continentales/ign_lineas_de_aguas_continentales_bi020/ign_lineas_de_aguas_continentales_bi020.parquet')
4GROUP BY 1
5ORDER BY entidades DESC, 1
6LIMIT 25;

Example spatial selection

1INSTALL spatial; LOAD spatial; INSTALL httpfs; LOAD httpfs;
2SELECT "entidad", "objeto", "fna", "gna", "nam", "fdc", ST_AsText(ST_Centroid(geometry)) AS centroide_wkt
3FROM read_parquet('https://data.source.coop/nlebovits/ign-argentina/themes/hidrografia-y-costas/aguas-continentales/ign_lineas_de_aguas_continentales_bi020/ign_lineas_de_aguas_continentales_bi020.parquet')
4WHERE ST_Intersects(geometry, ST_MakeEnvelope(-60, -35, -59, -34))
5LIMIT 20;

4WHERE ST_Intersects(geometry, ST_MakeEnvelope(-60, -35, -59, -34))
5LIMIT 20;

The second example’s envelope is illustrative; replace it with the area of interest.

Effective schema

Field	GeoParquet type	Note
`gid`	`int64`	Internal feature identifier published by the WFS.
`entidad`	`int64`	Feature code published by the WFS; the source does not publish a code dictionary.
`objeto`	`string`	Feature class or type published by the WFS.
`fna`	`string`	Full feature name as published by the WFS.
`gna`	`string`	Generic feature name as published by the WFS.
`nam`	`string`	Specific or qualifying component of the feature name as published by the WFS.
`fdc`	`string`	Source or lineage reference published by the WFS; its coding is undocumented.
`sag`	`string`	Agency-attribution field published by the WFS; its coding is undocumented.
`geometry`	`binary`	Vector geometry in WGS 84 (EPSG:4326).
`bbox`	`struct<xmin: double, ymin: double, xmax: double, ymax: double>`	Geometry bounding box where present.

Observed values

Non-null values from the first row group (a technical sample, not a statistical sample):

Field	Observed values
`gid`	804227; 877615; 878529
`entidad`	6
`objeto`	Muro de embalse
`fna`	Presa General San Martín - Futaleufú; Embalse Pichi Picún Leufú; Dique Piedra del Águila
`gna`	Presa; Embalse; Dique
`nam`	General San Martín - Futaleufú; Pichi Picún Leufú; Piedra del Águila

Quality, licence, and provenance

The WFS does not publish a complete data dictionary for these fields; the notes above distinguish confirmed semantics from undocumented codes. Treat attributes as a synchronized copy and check interpretations against the official source. The published licence is LicenseRef-Ley-27275; see the legal text. IGN is the producer and publisher; Nissim Lebovits processed this copy, which Source Cooperative hosts.
