| Search for base level data or derived products from a suite of sensors.
Build a list of data sets to order according to the parameters that you choose. Begin by choosing a sensor and the type of data product desired.
It will be possible to edit parameters along the way.

| The Moderate Resolution Imaging Spectrometer on the Terra and Aqua satellites observes the earth in 36 wavelength bands ranging from visible to thermal wavelengths with spatial resolutions ranging from 250 m to 1 km per pixel. |
|
|
|
|
|
| The Advanced Very High Resolution Radiometer on the NOAA polar orbiting satellites views the earth in 5 bands from the red visible to thermal wavelengths at about 1 km per pixel resolution. |

|
| Landsat 7 carries the Enhanced Thematic Mapper Plus instrument, which measures 8 distinct bands: six spectral bands in the visible and near infrared wavelengths, one higher resolution band in the panchromatic (green, red, and very near infrared), and one band in the thermal range. Resolution from this instrument ranges from 15 m to 60 m.
ETM+ data for Texas are precision terrain corrected and registered to the UTM coordinate system and the WGS 84 datum.

| Base data closely correspond to sensor measurements. Some calibration may be applied. All data are georeferenced. These data may be used to derive application specific products. |
|
|
|
|
|
| Derived products are the result of using one or more datasets along with calibration information to produce products more suitable for specific applications. The ETM+ data products are formatted for integration into GIS applications. |
