INTRODUCTION 
Before this project, the province of Santiago del Estero 
(Argentine) only had topographic charts in 1:250.000 
scale, built trought survey measurements made during 
the 70’s as a result of the works performed for the 
Militar Geographic Institute(M.G.L), in accomplishment 
with the law #22.963 (“Chart Law”). This law provided 
the cartography of all the country in sheets in 
1:500.000 scale, covering each one a rectangle of 2° 
in latitude and 3° in lenght, each one of which is divided 
in four sheets in 1:250.000 scale (1° in lat. and 1°30’ in 
lenght), this successively in nine sheets of 1:100.000 
scale (20’ x 30’) which is divided in four sheets in 
1:50.000 scale (10’x15’) and these in four in 1:25.000 
scale of 5’ in latitude x 7’30” in lenght. 
The Santiago del Estero province, whose position is 
indicated in the graphic, with the purpose of puting in 
action and increasing the knowledge of the territorial 
wealth and its distribution, to build economical and 
statistics data which serve as the basis to the planing 
actions; carry out these tasks, according to its own 
functions, established in the Provincial Cadastre 
Territorial Law. 
To accomplish this work the province provided us 
seven LANDSAT TM Satelital Images, of 1994, which 
cover almost all the provincial territory. Two small 
stripes remained without cover in the east and 
southeast. This zones were covered with other four 
images of 1997 acquired recently, because it was 
impossible to obtain 1994 images of this sectors. 
The elaboration of this work was commended to the 
Survey Departament of the Exact Sciences and 
Technology of the Nacional University of Santiago del 
Estero, by means of an Agreement signed between the 
General Cadastre Direction and the University, in July, 
1997. 
The area to cover is situated in the north sector of 
Argentina, aproximately between the 25° 30’ and 30°45’ 
of South latitude paralels and the 61°40’ and 65°30’ of 
lenght meridians, and has a surface of 135.254 Km 2 . 
In 1:100.00 scale a total of 96 charts are necesary to 
cover the whole provincial territory, shown in the 
following figure:

PLANIFICATION 
The general production process of a Image 
cartographic sheet, involve diferents stages; the first is 
the acquisition of the images.One must pay atention to 
the capture date and the best band combination. In our 
case we have not option and we had to work with the 
images which possesed the province. 
The process issued are the georeferentiation, 
rectification, the land recognition, and the cartography 
edition. Considering these aspects, planification 
previse the following steps:
