What impressed me the most is that through AgriSat SPIDERwebGIS we have been able to see exactly where the different, productive areas of each plot are, confirming what we already knew and detecting others which we had not been  able to see until then.

Additionally, as an interesting story, AgriSat SPIDERwebGIS allowed us to detect a leak caused by mice chewing and breaking micro-irrigation tubing. This caused one of the sectors to irrigate for nearly four hours. In this sector, the NDVI values had risen above the rest. This was seen from the satellite and the problem was detected even before we noticed it in the field.

In the past, farmers used to carry out many more field inspections. Nowadays, however, we spend a lot of time on the tractor and we have put aside some of those good practices.  With the arrival of AgriSat SPIDERwebGIS, a user can understand what is happening in the plots better than the farmer in the field.

It is a revolutionary system and I am sure that in the near future, all farmers will carry out their own crop monitoring and control with the help of this type of tool. This means that it will be integrated into our daily lives.

As a field technician, I consider AgriSat SPIDERwebGIS a virtually essential tool in my daily task of monitoring the different crops I work with.

When we visit different plots, we often make the mistake of accessing through the same places: places near roadways, edges of lots, places close to irrigation management areas, etc. However, when the plots are large, problems usually occur in more remote areas, making them easier to escape our supervision.  A quick view of Agrisat images before our visit to the field will give us an idea of the current situation of the crops in those areas where crops have a lower response. This gets use on the right track to the areas that need to be inspected.

Another problem that AgriSat SPIDERwebGIS also allows us to detect is the location of areas with poor irrigation, from pivot to tubing and even drip irrigation.

Other uses which make AgriSat SPIDERwebGIS an essential tool in my daily tasks include forecasting irrigation needs, as well as comparing the potential productivity of the different plots. Once you become familiar with its use, which is relatively easy, you cannot imagine a visit to the field without previously looking at images from AgriSat SPIDERwebGIS.

(Agricultural Engineer, HIDROSOPH consultant)

After working with remote sensing images for over ten years and getting the feeling that the methodology was inadequate for the daily management of crops, for the establishment of clear references to compare species, varieties and productive years, in other words, for its practical application, the use of AgriSat SPIDERwebGIS, its working method with NDVI images and the setting  of numerical value curves  has allowed me to redirect my approach to remote sensing in agriculture and its incorporation into my daily life as a key tool in crop management.

After using all kinds of new technologies for irrigation management in agriculture for over fifteen years, I think that the approach and use of NDVI images proposed by AgriSat SPIDERwebGIS is the most revolutionary, simple and practical that has appeared in recent years and which will shape the future of efficient irrigation management of crops.
