COMMISSION IV: CARTOGRAPHIC AND TOPOGRAPHIC APPLICATIONS
The world has witnessed in the last decade the extraordinary develop-
ment of artificial satellites. In 1972 and 1973, when the ERTS and SKYLAB
missions were carried out, the Instituto Geográfico. Militar started to attach
a particular interest to this new source of cartographic information.
On this last matter, the Instituto Geográfico Militar performs co-re-
search work at the 496 B Experiment named "General Evaluation of the
SKYLAB satellite imagery for Latin American cartography”. It accordingly
directed its efforts to the preparation of expeditious cartography, scale
1:250 000, of flat regions.
With the mentioned purpose and taking into account the coverage
made by the satellite images of SKYLAB lll, frames 200-199-198 and 197
obtained with S 190 B camera, were selected. They cover a large portion
of the “Chascomüs” sheet (3557-111).
This sheet was selected because it was printed and obtained through
compilation of the existing regular cartography at scale 1:50 000. There-
fore, it is an excellent "testing ground" regarding the precision that can
be obtained in restitution, as well as the verification of the photointerpre-
tative quality achieved when using satellite images at scale 1:950 000.
The area which was covered and the geographic situation of the re-
gular and expeditious mapping performed during the period June 1972-
June 1976 is shown on graph Enclosure N? 2.
COMISION IV: APLICACIONES CARTOGRAFiCAS Y TOPOGRAFICAS
El mundo, en este ültimo decenio, ha sido escenario del desarrollo
inusitado de los satélites artificiales y es en especial, en 1972 y 1973
cuando se concretan las misiones espaciales ERTS y SKYLAB, que el
Instituto Geográfico Militar toma particular interés por esta fuente nove-
dosa de información cartográfica.
Justamente, en este ültimo aspecto, el IGM actüa como coinvestiga-
dor en el Experimento 496 B "Evaluación General de las Imágenes Sate-
litarias SKYLAB para la Cartografía de América Latina".
En relación con este experimento se dirigió los esfuerzos hacia la
confección de cartografía expeditiva a la escala 1:250000 en regiones
llanas.
