GOES Satellite Imagery for GIS

The IEM receives a "real-time" feed of GOES East and West satellite imagery in GINI format. We process this into GIS-ready RASTERs for download and web services. This page details this dataset.

The GOES (Geostationary Satellite) provide the commonly seen views of clouds from space. The IEM receives a near real-time feed of this data in GINI format and processes it into geo-referenced PNG raster files. A directory of these files can be found here, but the native grid projections may be difficult for you to use. The IEM projects this data onto a simple lat/long grid (EPSG:4326) and you can find those files here. Besides the raw files, the IEM also provides OGC web-services of this imagery.

AWIPS Projection Data

The raw GINI data files are provided on predefined grids used by the National Weather Service AWIPS system. Here is an attempt to cross reference these grid numbers into Proj4 strings.

AWIPS Grid Proj4 String ESRI Projection files
208 proj=merc lat_ts=20 x_0=0 y_0=0 a=6371200.0 b=6371200.0
211 proj=lcc lat_0=25 lat_1=25 lat_2=25 lon_0=-95 a=6371200.0 b=6371200.0 awips211.aux.xml awips211.prj

These AWIPS projection imagery files can be found here. You will find three files for each image: the raw PNG imagery, the world file, and a JSON formatted metadata file.

Since 20 Dec 2005, the IEM has archived 4km composites of East/West imagery.

Since 8 March 2009, water vapor channel was added to the archive as well.

Since 21 June 2011, the IEM started archiving GOES East and West vis,ir, and water vapor imagery in PNG format on the AWIPS 211 projection.

Since 14 March 2012, the IEM started archiving all of the GINI processed imagery.

22 March 2012, removed the confusing filenames of including the GOES satellite identifier in the filename. This causes problems when the satellites change from east to west.
