Information Required for Remote Sensing Project Planning

WHO ARE YOU?

  1. Name, address, phone, fax, email of all contacts

WHAT ARE YOUR REQUIREMENTS?

  1. Data product [processing level]
    Level 0 raw sensor format at original resolution [for Borstad use only]
    Level 1a Level 1a radiometrically calibrated at the sensor [for Borstad use only]
    Level 1b Level 1a with a separate but synchronized file of aircraft attitude and GPS data to permit mapping [usually only used by university groups on limited budget and who want to do research on correction techniques]
    Level 1c Level 1a with aircraft roll corrections and a separate ASCI file of latitude/longitude to permit approximate mapping [ditto]
    Level 1d Level 1a data with radiometric calibration and mapping
    Level 1e Level 1d data with partial atmospheric correction to remove most of the effects of atmospheric scattering
    Level 2 Geophysical or environmental parameters derived from Level 1 data (imagery classified to produce thematic maps)
    Level 3a Level 1b or level 2 data mapped to geographical coordinates using on-board attitude and position data only [CMAP]
    Level 3b Level 1b or level 2 data mapped to geographical coordinates using onboard attitude and position data, differential positioning and additional ground control points [GCPWorks].
    Level 3c Level 1b or level 2 data mapped to geographical coordinates using onboard attitude and position data, with additional ground control points and a Digital Terrain Model
    Level 4 Thematic maps created from level 3b or c data. We work closely with field ecologists to create accurate classification maps
  2. Spatial resolution required?
  3. Data format for delivery is via CD for small volumes; 16 bit files in ENVI, PCI or ERDAS format

FLIGHT PARAMETERS

  1. What is the size and dimension of the target areas?
  2. Aircraft altitude depends on spatial resolution required (11,000’ or 3350 m Above Ground Level = 4 m pixels and 2 km image swath and allows 15 spectral channels). We usually use north-south flight lines, with line spacing giving approx 50% overlap. This allows correction for atmospheric scattering and provides redundant data.

WHEN

  1. What are the target acquisition dates [how firm are these?]
  2. What are the target acquisition times [are the times to coincide with tides or in situ sampling?]
  3. What data delivery is desired? ‘turn-around’ (faster = more expensive)

WHERE

  1. Location of targets – latitude/longitudes [is any target near any sensitive installation such as a power plant, military reserve or dam?]
  2. Terrain – max/min altitude
  3. Normal/expected weather conditions at time of mission [snow, temperature, winds, cloud]
  4. Can you provide topographic maps, high altitude aerial photos or SPOT imagery?
  5. Can you provide a digital map vector file to assist in navigation of imagery?
  6. Can you provide a digital terrain model if Level 3c data is required?

WHY

  1. What is the target? [or which bands to use]
