Software support for EASE Grids
| Software & Codes | EASE-Grid (Spherical Projection) | EASE-Grid 2.0 (WGS 84 Projection) |
|---|---|---|
| HDFEOS 2.xx HDFEOS 5.xx | Supported | Cylindrical projection is supported. Azimuthal is not supported. |
| PROJ.4 | Supported | Azimuthal and cylindrical EASE-Grid 2.0 supported in PROJ 4.8.0 (13 March 2012). Azimuthal projection was supported in PROJ 4.7.0 (23 September 2009). Bug in PROJ 4.7.0 resulted in error of ~15 km when transforming points near equator for cylindrical EASE-Grid 2.0 data. |
| GDAL Tools | Supported | Supported, with correct version of PROJ.4. |
| EPSG Codes | North: 3408 South: 3409 Global: 3410 | North: 6931 South: 6932 Global: 6933 Note1: Use these ProjectedCRS Codes for EPSG Version 8.6 or later. Note2: GDAL tools built with the correct version of PROJ4 will work on the EASE-Grid 2.0 projections with PROJ4 strings even if it's built with EPSG Codes earlier than 8.6. |
| ENVI | Azimuthal supported. T. Haran (NSIDC) has written procedure to add cylindrical equal-area to ENVI. Requires simple modifications to support header information for EASE-Grid data sets. ENVI cannot read/write user-defined projection information from/to GeoTIFF, but it can do so with its own ENVI header format. | Azimuthal supported. Cylindrical equal-area requires user-defined projection information; simple modifications to support header information for EASE-Grid 2.0 data sets are forthcoming. |
| Mapx | Supported | Supported |
| ArcGIS | Supported | Supported |
| ERDAS | Supported | Supported |
