Goal 4: Multi-spectral mosaic for Vegetation dynamics

Specification of Final product 4:

• Must match or outperform the 2013 product Bert20130602AOI1MultiRefv2.tif
  • Mosaic resolution: better than 0.5 m

(HEMAV will not process the imagery but must provide the necessary intermediate products)

4.1. Flight characteristics and equipment

• Area to be covered 400m x 700m
  • Shapefile Bertolina AOI prat
• Camera: Tetracam 6 bands
  • Filter configuration:

• Ginbal: designed for Tetracam
• Height: 120 m ?? HEMAV?

4.2 Deliverables

Images and necessary files to create the multi-spectral mosaic using Agisoft PhotoScan

• X images of XXX cm * YYY cm and xxx resolution HEMAV?
• Overlap among images ~80% HEMAV?
• Images of calibration targets at the begining and end of the flight
  • Size of calibrated targets: XX * XX ALOBO
• File 1 with
  • image name
  • time of acquisition
  • X coordinate of image center
  • Y coordinate of image center
  • Z coordinate of image center
  • pitch
  • rol
  • yaw
• FIle 2 of flight parameters (to evaluate flight quality) with
  • time
  • X,Y,Z
  • pitch,yaw,rol

4.3. Field Work

4.3.1 Ground marks

• 12 ground marks with sub-metric GPS positioning must be visible in the ensemble (ALOBO)
  • HEMAV: Do you have any special geometric targets? how many?
  • HEMAV (Marc?): is 12 enough?
• Calibration targets (HEMAV)

4.3.1 Field sampling

Stratified random sampling design using the combined information of 2013 and the iorto of ICC (ALOBO!!)

• Variables (TBD on 20150615):
  • Concentration of chlorophyle
    • SPAD?
    • samples + analysis
  • Lignine or any other indicator of woodiness
  • Biomass (green and brown)
    • Vertical photogrphy?
  • (G)LAI?

BIOGEI: I (Agustin.Lobo@ictja.csic.es) need help with this!!
