Apple is also gathering new high-resolution satellite data to combine with its ground truth data for a solid base map.
In the first example we generate a large model for a genetic regulatory network that can be used to produce ground truth data for a microarray simulation [ 25].
It demonstrates that satellite images obtained under certain climatic conditions, and accompanied by adequate 'in situ' ground data, can provide a basis for an operational heat stress mapping system.
He notes that $4 million has already been earmarked over 3 years to gather satellite and ground-based data for a study of the impact of warming on Himalayan glaciers.
In future research we intend to evaluate the alternative "average activity descriptor" described in [8], to obtain ground-truth data for a quantitative validation of the algorithms' detection performance.
As examples, Figure 4 depicts the GIS-based concept for assessing land use impacts on habitat (Dale et al. 1998), and Figure 5 illustrates combined risk contours developed from GIS-linked ground-water data for a large radioactively and chemically contaminated site (Pacific Northwest National Laboratory 2002).
The need for representative ground data obtained using a robust spatial sampling strategy is highlighted and the example of how this was achieved in MODIRISK, a project aiming at mapping mosquito species and biodiversity patterns in Belgium, is given.

The network is being established jointly by GFZ and Jet Propulsion Laboratory (JPL) to ensure adequate ground data availability for processing of globally distributed GPS occultation events.
No correction for large-scale, slowly varying magnetospheric fields has been applied to the ground data used for the SAREG model.
