7. Geographic Information System (G.I.S)
GIS technology is aimed to understand facts which occur on earth using digital images on a computer

8. Geographic Information System (GIS)
EACH DATA POINT IS AN ELEMENT SET UP IN THE SPACE THROUGH A PREDEFINED SYSTEM OF COORDINATES

9. IMPLEMENTATION
. Rearrangement of existing data bases and set up of new ones
. Election of a system of geographic projection
. Compilation and generation of cartography and digital images
. Election of a GIS system.
. Generation of program rutines to link the different data bases

10. HOST CENSUS. CHEMICAL AND CULTURAL CONTROL
APLICATIONS
FRUIT SAMPLING
TRAPPING
HOST CENSUS. CHEMICAL AND CULTURAL CONTROL
SIT

11. TRAPPING . Exact location of each trap
. Spatial distribution in routes
. Dispersion of fly catches
. Additional information on individual traps

13. FRUIT SAMPLING . Coverage and distribution of fruit sampling
. Exact place of each sampled location
. Additional information of each fruit sample

15. CENSUS . Host distribution . Location and quantity of each species
. Planification and coverage of Chemical and Cultural Control

17. SIT . Planification of the areas to be released
. Control of plane releases
. Information about each flight
. Analysis of the sterile insect dispersal

18. Aerial releases Area under SIT: 160,000 ha Strain: TSL
Sterile males released per week:
Density : males/ha
Type of release: aerial in paper bags
Flies per bag: 2,600 males
Bags per week: 38,500
Number of blocks: 36
Area of each block: 4,000 – 4,500 ha
Frequency: - weekly in 17 blocks
- twice a week in 19 urban blocks
Airports under operation: 4
Planes under operation: Cessna 172, Cessna 182
Capacity of planes: 700 bags (1,820,000 males)
Weekly flights: 55
Average time of each flight: 50 minutes
Weekly flight hours: 45
Total flight hours: 2000
Flight conditions:
- Altitude: feet
- Mean speed: 100 miles/hour
- Distance between bands: 300 m
- Frequency between bags: 4-5 seconds

22. GIS IS AN EFFICIENT TOOL Useful on any program of pest control
. For Administration
. For Analysis
. For Interpretation
. For Diagnosis
. For Planification
. For Execution
. For Control
Useful on any program of pest control
