Multitemporary rice crops evolution monitoring using satellite images. The monitored rice crop corresponds to an experimental parcel of the "Escuela Agraria de Artigas", Uruguay (season 98/99). 1. Comparison: compositions false infrared of the satellite Landsat-5 versus ground truth photos 2. Comparison: Normalized Differential Vegetation Index (NDVI) versus ground truth photos The images that we can see here, are a subscene of a Landsat image that includes an area of some few square kilometers. A Landsat quadrant "full scene" includes an area of 185x185 kmts whereas a subquadrant of the same one covers 90x90 kmts., approximately. This means, that a kind of analysis like the sight in the example (that has been made on a single rice crop) can do extensive to everything an influence area, and there is more: it can become extensive towards other economically competitive zones of rice interest (even outside borders). Although the rice crop isn't a thematic area that we have study in depth, the experience obtained in the application of the satellite remote sensing in other agricultural sectors, makes us suppose that the design of models that we can systematically apply in other areas are perfectly viables for the rice crops applications, as well as other extensive crops, showing great advantages with respect to the remote sensing: those crops whose surfaces average don't have more than 3 hectares usually require analysis more complexes than those of great surface crops. Despite it, we have obtained very good results in the studies made in tobacco, whose surface average planted by parcel is of approximately of 2.5 hectares (this can vary according to the different countries).
