OUR MISSION

Eleven years ago, a group of technicians of different areas, began to study the possibilities of the application of the Satellite Remote Sensing in our region. That group today is TELEDET. 
During this lapse we work in several projects of Remote Sensing application, particularly focused to the agricultural activity. These studies were made not only for clients in our country, but  also for foreign companies (Ex. the USA, Zimbabwe, Brazil), involving subjects such as the tobacco culture and forestry. 
From 1999 we have a satelite ground station (first of these characteristics in our country) in the zone of "El Pinar", Canelones, Uruguay, with which we can obtain realtime images of  satellites such as NOAA, GOES and METEOSAT. In addition, for works that imply greater precision,  we are working with images of high resolution satellites. We obtain these images from different international suppliers (see satellite images). We have also new generation software and hardware tools, which we use for the intention of our studies. In this site, You will find a series of images and examples of Satellite Remote Sensing application. As we see, the diversity of applications (proven and potential) of this discipline is enormous, and is very probable that a possible problem that You wish to solve, (or that can be very onerous using classic technics) it isn't contemplating in  this site. Being thus, please contact us, in order to evaluate the possibilities that this  technology offer to the solution of your problem. Next we offer a pair of examples of the  advantages cost benefit of the satellite remote sensing.

Satellite Remote Sensing benefits and comparative advantages With respect to the classic techniques

Example #1: Forestry 

We will propose as first example an area dedicated to the forestry in Uruguay. Let us suppose as the objective of the study is the creation of a forest inventory, that includes the meassurement of the total surface for the different planted species, its different ages and their diverses cultural handlings. Once let us suppose that during the year, you needs to update this forest inventory including a calculation of the surface harvested in that period for each species, as well as, how many hectares has been transplanted during the same lapse. Finally, we suppose that the area covered by this forestry is 4,000 hectares or more. Which is the cost of making annually an analysis of this nature using field classic techniques? (take in mind the supposed surface). 
Which is the cost of updating annually this forest inventory contracting aerial photography services? 
The benefit that the satellite remote sensing proposes for the forestry industry bases on the viability to make this kind of studies with a sensibly smaller cost than the classic techniques and/or of aerial photography, and with a much greater update frequency (semestrally, for example).

Example #2: Rice culture

Let us suppose that it's desired to make a prognosis of the yields of the rice in a certain influence in Uruguay. 
Which is the cost of make a study if de development of the differents rice cultures contracting aerial photography services of all "Rio Olimar" basin, for example? However, the experience show us that to analyze the variables that can determine the yield of any short period culture (case of the rice), is essential to make a multitemporal monitoring. This supposes that we need to make not less than two samplings during that period, with the purpose of studying the culture evolution. 
How much it would cost to make two aerial photography samplings for the area before mentioned? 
The magnitude and cost of this task discard the use of the aerial photography in the analysis of this kind of culture. A multispectral satellite image Landsat cover an area of 185x185 kilometers, whereas a  subquadrant of this image covers an area of 90x90 kilometers. The spatial cover of these images, as weel as their versatility as far as processing and analysis, does perfectly viable this kind of studies as far as the low cost. 
On the other hand, the multispectral nature of these images allow us to reach analytical results impossible to obtain with the classic aerial photography. 
We don't try to disqualify tthe traditiona panchromatic aerial photography as a remote sensing tool. Simply we want to exemplify the advantages that the satellite offers in certain kind of applications.
