In 1980, at the ISP & RS Congress in Hamburg one of the passed Resolution 
(V.VII/1) dealt with the structure of the Working Groups in Commission VII. At 
that time it was recommended 
"a) to continue the existing Working Groups activities; 
b) to more clearly define the activities and names of 
the Working Groups, and 
c) to encourage integrated operational remote sensing 
activities within the Working Groups of Commission VII." 
Accordingly, after the Congress, Mr. Louis Laidet, President ISPRS Commission 
VII, renumbered the Vegetation Damage Working Group (WG-VII-11), and renamed it 
"Vegetation Damage in Agriculture and Forestry", and named Prof. Dr. P. Murtha 
as its chairman. Among the specific concerns of WG-VII-11, President Laidet 
suggested the following topics: 
"a) vegetation diseases detection and surveillance; 
b) forest diseases detection and surveillance; 
c) vegetation and forest risk evaluation (frost, floods, 
fires....), and 
d) inventories and mapping of vegetation damages." 
Further, Resolution T.VII/2 at the Hamburg Congress dealt with basic studies in 
remote sensing of vegetation damage assessment. At that time, the Congress 
  
  
  
   
   
    
   
    
  
    
    
   
   
   
     
      
   
   
   
  
  
    
  
  
   
    
     
    
    
    
      
ations. recommended that: 
"a) Commission VII supports the concept of, and encourages 
rs could research organizations to become involved in basic 
studies of normal and stressed plants relative to spectral 
reflectance and emittance, and to relate these data to 
remote sensing data, 
Fapporteurs b) ground truth data should be more precisely defined, and 
mposia - these data should also recognize meteorological conditions, 
and 
ical c) when possible, remote sensing should be included as a 
nough component part of general vegetation damage research 
; activities." 
erally The final resolution (T.VII.3) dealing with vegetation damage and passed at the 
Hamburg Congress dealt with a manual for remote sensing of Vegetation Damage 
i Assessment. In the rsolution, the Congress recommended that 
"a) Commission VII supports and encourages the production of 
a Users Manual for Remote Sensing of Vegetation Damage 
ort Detection and Assessment, 
b) the manual should provide ways of accuracy measurement, and 
c) Commission VII supports and encourages the further 
publication of updated annotated bibliographies dealing 
with remote sensing for vegetation damage detection and 
assessment,"
