[Qgis-user] downloading map data

[Carlos Cerdán]

Hi everybody, especially peruvian users:

Not exactly a QGIS issue, but this can be useful about the data to work in
it:

Yes, our official geographic agency offers public information as private
information, and cost is very expensive. But looking here and there, we can
download free shape layers to begin with a "respectable" peruvian
geographical base:

1. ESCALE <http://sigmed.minedu.gob.pe/descargas/>: topo maps to 1:100,000
scale.

2. INEI: Censo Nacional Agrario 2012
<http://series.inei.gob.pe/cenagro-espacial>. You can get updated
administrative limits from SEAs (but you have to dissolve twice to get it).

3. GEOCATMIN <http://geocatmin.ingemmet.gob.pe/geocatmin/>: mining cadastre
and related shapes.

Best whishes
