What is the primary goal of the project?
Define the problem.
How can remote sensing be applied to assist in solving the problem?
What spatial resolution is need?
Determine the minimum, maximum, and/ or optimal GSD (ground sampling
distance).
What is the target or what is being mapped?
High-resolution panchromatic (black and white) aerial photography may be
sufficient.
Define what spectral bands are needed.
Will field work be included in the project budget?
What detail is needed from the imagery?
What spectral resolution is needed?
Set bandwidth and proximity.
Determine timing and temporal resolution requirements.
Select season(s) and time frequencies.
How urgent is the data needed?
To capture an emergency event or temporal phenomena an airborne system may
need to be promptly employed.
What repeat cycle do we need?
Each sensor system operates on a different cycle.
When will ground truth data be collection?
Image data acquisition ideally coincides with ground truth data collection.
What are the weather and light conditions?
Select radar or optical imagery or adjust acquisition timing to accommodate for
variable atmospheric conditions.
What level of processing will be performed by the vendor?
For example, choose basic processes such as radiometric, atmospheric, and geo-
metric corrections should be considered.
What accuracy do we want?
Set vertical and horizontal limits.
Where is the project geographically located?
Specify upper left/ lower right hand corner Latitudes and Longitudes.
