You can use IrriWatch data for free during a trial period of 14 days. One order can comprise of several fields. Trial periods should be taken in the cloud free irrigation season only. After this trial fortnight you will be contacted on continuation. If positive, you get an invoice with a payment condition of 14 days. If not paid on time, the free data delivery is discontinued.

You can register both rainfed and irrigated fields. The minimum area of each field (or part of a field) is 0.5 ha. The minimum order is 25 ha, and you can reach this minimum acreage with an associate.

The best is to try the product for 14 days and compare it against your own experience and measurements from field devices, provided you have them available. There is also an annual IrriWatch Validation Book (link). The irrigation service is less accurate for vegetation cover less than 10%. We provide a quality flag every day and for every polygon which reflects actual vegetation and cloud cover conditions.

The processing of the images is based on an energy balance, so the procedure to compute ET and soil moisture is neither dependent on the type of crop, nor its development stage. A distinction is made between C3 and C4 crops for computing the carbon fluxes and dry matter production. It is one of the reasons that crop types need to be provided.

Yes the price per unit land goes down from € 10/ha/yr at 1,000 ha to € 1/ha/yr for 100,000 ha and larger areas. The area – price table applies only per country. This is the price for a Basic Package. Dry Land and Premium Packages are also available.

No, the agreement foresees delivery of the data for a period of 12 months according to the delivery period proposed and agreed upon. The contract will be renewed after one year for another annual cycle, if approved by the client.

Yes, we compute the recommended amount of Applied Water for every pixel of 10 m x 10 m. This can be one block of drip lines or a section of a center pivot system

The IrriWatch App is downloadable in the PlayStore and AppStore. It has a demo button for reviewing its functionality without requiring any registration. For seeing your own fields, you get a login code from the registration process. You can use that also for the Web Application. Excel and csv files can be created from the Web Application for your own data management and applications.

Yes, you can send a request for an API raster data service to support@irriwatch.com without extra charges. You can then pull down your daily fresh data. You can integrate the data into ongoing services for the farmer and irrigation community. The original raster data will be deleted after 6 days.

The first delivery takes a few days because every new order has to be checked and verified. Once commenced, daily irrigation advisory data is provided every night at 3.00 hours local time based on yesterday’s satellite measurements taken between noon and 2 PM. It is a real-time product.

Yes, the subscription fee is based on a continuous period of 12 months.

A company discount is provided if more areas are supplemented using the price-area scale. This is effective immediately on the date of any new land being registered. Hence, if new land will bring the total area to a new scale level, the discount price applies to this new fields. For fields signed in before, the 12 month agreement applies. These “older fields” will receive the discount at the moment of agreement renewal, i.e. when the 12 months cycle is expired.

 The irrigation data is most accurate if the vegetation cover exceeds 60% (60% leaves; 40% soil) and there are no clouds with skies being free from dust and aerosols. These days get a quality label of “excellent”. Emerging crops have a vegetation cover less than 15%, and the accuracy is under such situation always less than 60%. They will get the quality label fair (<60%), poor (<40%) or bad  (<20%) according to the actual vegetation cover of the day of delivery. In general, irrigation scheduling accuracy thus increases with crop development stages.

No, but you can send the Google Earth files to support@irriwatch.com from where a dialogue will start on the completion of the registration process, including all the codes.

Every shape file must contain the international standard WGS84 geo-reference system. Other systems will not be accepted

A green bar implies that the climatological cloud cover is less than 50%. A yellow bar means that together with an adjacent green bars the minimum cloud eligibility is reached. IrriWatch data is not delivered for months with red bars. Hence, the delivery period relates to months with yellow and green bars only. If all months appear red, contact support@irriwatch.com

Yes, if you register your company and email address, you will  get a unique login code. With this login code you can real time monitor the demo farm in Egypt. You can inspect raster and vector maps  of the region. Also graphs, tables and excel sheets of this farm with 23 fields. If you like it, you can assign your own irrigation fields. 

The dates represent image dates. Various types of satellite measurements are collected between 10 AM and 4 PM. After that, the collection process starts and the image processing takes place. The irrigation advice is created overnight. 

The images from yesterday and the weather forecasts for today are merged during the night for making an irrigation advise for today. Hence the min & max Adviced Water are always for today (ahead of time). 

Applied Water is computing the amount of water applied yesterday, so it is looking backward. Adviced Water is based on the weather forcecasts of today and look forward. Min & Max Adviced Water should be considered for irrigation planning. Applied Water should be used for monitoring and compliance purposes

ET represents the actual consumptive use of water that transfers into the atmosphere by means of Evaporation E, Transpiration T and Interception evaporation I. One part of this ET originates from rainfall. ETaw is the fraction of ET that originates from Applied Water only. It is an incremental ET due to irrigation practices only

The best is to try the product for 14 days and compare it against your own experience and measurements from field devices, provided you have them available. There is also an annual IrriWatch Validation Book (link https://www.irriwatch.com/assets/files/irriwatch-validation-book-2020-1.pdf ). The irrigation service is less accurate for vegetation cover less than 10%. We provide a quality flag every day and for every polygon which reflects actual vegetation and cloud cover conditions.
