Description of the Digital Products

Satellite: LANDSAT 5 TM

Corrections

1.Level 4: systematic corrections. Bands 1-7

2.Level 5: Systematic corrections. The image is georeferenced using the satellite

ephemeris. Resampling is performed using nearest neighbors (cubic convolution as optional). Bands 1-7.

3.Level 5+: Systematic corrections. The image is georeferenced from level 5 product

using cartography by means of a single control point. IMG (Erdas) format. Bands 1-7.

4.Level 6: Systematic corrections. The image is georeferenced using 6 or more cartographic or ground control points. Resampling is performed using nearest neighbors

(cubic convolution as optional). Rectified to a cartographic projection. Bands 1-7.

5.Level 6i: Systematic corrections. The image georeferenced using 6 or more cartographic or ground control points, from level 4 product. Rectified to a cartographic projection. IMG (Erdas) format. Bands 1-7.

Corrections

1.Level 4X: Systematic corrections. Bands 1-7 (Band 6 with 2 gains).

2.Level 4P: systematic corrections. Band panchromatic 8.

3.Level 4XP: Systematic corrections. Bands 1-8.

4.Level 5X: Systematic corrections. Image georeferenced using the satellite ephemeris

data. Resampling performed by nearest neighbors or cubic convolution. Bands 1-7 (Band 6 with 2 gains).

5.Level 5P: Systematic corrections. Image georeferenced using the satellite ephemeris

data. Resampling performed by nearest neighbors or cubic convolution. Band panchromatic 8.

6.Level 6XP: Systematic corrections. Image georeferenced using 6 or more cartographic

or ground control points. Resampling performed by nearest neighbors or cubic convolution. Bands 1-8. Rectified to a cartographic projection.

Corrections

1.PRI: Systematic corrections and speckle reduction (using 3 looks) image.

2.GEC: Systematic corrections and speckle reduction (using 3 looks) image.

Georeferenced using the satellite ephemeris and rectified toa cartographic projection.

Corrrections

1A, 1B, 2A. Similar to Landsat 4-6 levels.
