This read-only GDAL driver is designed to provide access to the products generated by the IRIS weather radar software.

IRIS software format includes a lot of products, and some of them aren’t even raster. The driver can read currently:

- PPI (reflectivity and speed): Plan position indicator

- CAPPI: Constant Altitude Plan position indicator

- RAIN1: Hourly rainfall accumulation

- RAINN: N-Hour rainfall accumulation

- TOPS: Height for selectable dBZ contour

- VIL: Vertically integrated liquid for selected layer

- MAX: Column Max Z WF W/NS Sections

Most of the metadata is read.

Vaisala provides information about the format and software at http://www.vaisala.com/en/defense/products/weatherradar/Pages/IRIS.aspx.

NOTE: Implemented as `gdal/frmts/iris/irisdataset.cpp`.
