The outputs of the analysis of the sampling points 
will be of the following form: 
1. Coffee or no coffe 1.1. Diameters and spacing 
(automatically determined) 
2. Citrus % Forest data (preselected) 
3 Unclassified data. 
Item sub-1, above, provides valuable information 
on the age of coffee trees and additional information on frost at- 
tack levels and information which is of use in coffee leaf rust - 
control programme. In pre-determined locations it might also be 
possible to provide information on forest parameters such as mean 
crown diameters and density of stands which could provide wood vo 
lume inventory estimates. 
STATISTICS PRESENTATION REQUIREMENTS 
  
Two basic forms of presentation would be useful - 
for coffee statistics. One would be a statistical tabulation and 
analysis of the data received giving an analysis of the population 
sample for each region (perhaps at State level, the present prac- 
tice using conventional photographic techniques) in terms of con- 
centration of coffee, spacing of coffee, diameter of coffee, etc. 
The second form of presentation would be a map, constructed on the 
basis of the mapping camera output and the sampling camera data. 
A simple thematic mapping form would be sufficient since this is 
now the form used conventionally at IBC since 1971, based upon a 
grid systematic sampling procedure. 
CONVENTIONAL VERSUS COMPUTER ANALYSIS AND MAPPING 
  
The former conventional interpretation of 500.000 
square kilometers of coffee crops has taken more than one year to 
be completed. A further six months were required for map prepara-
