| - | ====== Data Format Policy ====== | ||
| - | In order to ensure interoperability for all different platforms and operating systems used by partners, we introduced strict guidelines about formats to be used for both data and documents. | ||
| - | ===== Geodata formats policy ===== | ||
| - | |||
| - | All formats used to exchange geo data of any kinds among partners must be INSPIRE compliant and based on [[http://www.ogc.org/|OGC (Open GIS Consortium)]] recommendations, in order to ensure easy interoperability, even when different programs are used. Also, keep in mind that target sites are localized in various areas of the globe, so a global coordinate reference system should be preferred. | ||
| - | |||
| - | ==== Raster data ==== | ||
| - | |||
| - | * Preferred format (up to 4GB): multiband/multifile GeoTiff | ||
| - | * Reference ellipsoid/datum: WGS84 | ||
| - | * Reference plane projection: UTM (zone depends on area considered -> to be detailed) | ||
| - | * Optional Color table: 24 bits (note that only 8 bit lookup tables are supported by all programs) | ||
| - | * Use NULL/ALPHA whenever reasonable/useful | ||
| - | * Always provide a companion world file (.TFW) to allow at least a rough localization for people who do not use GIS tools | ||
| - | * You have to adopt a suitable tiling for big grids (> 4.GB) and possibly provide a vector skeleton of the tiles boundings in geo coordinates | ||
| - | * Avoid as much as possible proprietary formats (e.g. ECW, Kakadu, MrSid, etc.) | ||
| - | * Eventually ask for advice before providing/ordering data | ||
