Benchmarking 2010/How to get some sample data

How to download sample data

The datasets will require some time to be merged and prepared, and the simbology still isn't fully decided on. In the meantime, you can download some sample data by following these steps:

• Go to http://centrodedescargas.cnig.es/CentroDescargas/index.jsp

This is the website where the Spanish National Mapping Agency publishes some datasets

• On the top of the page, hit the Welcome link to enter the english version of the page

• Register for a new user. You'll need to enter the desired username, password, repeat password, full name and surname, email, and solve a captcha.

• Enter your account details to log in.

• Go to Advanced search

• In the "products" drop-down menu, select either BCN25-BTN25 for vector data, or Ortofoto PNOA Máxima Actualidad for aerial imagery.

• In the "MTN50 sheet number", enter any number between 1 and 1108.

Barcelona is 420-421; Madrid is 559. You may want to check a sheet reference (caution: sheet reference is a 17MB image)

• Hit "See list of products". Select a file to download. You will see the license for the data, which boils down to "do not make any commercial use of this data" and "say that the data comes from the IGN"

• You will see a survey. Hit "No enviar y continuar con descarga"

• Hit "Click here yo begin download"

Raster data issues

Remember that the baseline of the OSGeo Benchmark for raster data are GeoTIFF files, but note you can only download ECW files. We will be converting the ECWs to GeoTIFFs.

Vector data issues

Once unzipped, a sheet of vector data contains lots of shapefiles. The shapefiles will be merged, and most probably only the most interesting themes will be used.

A letter after the theme code explains what kind of geometry the shapefile contains. P stands for Point; L stands for Line; S stands for Surface (Polygon).
