Online Precision Farming Analysis


A new way to increase the value of your precision farming investment
– By becoming part of a community of shared information!

While most farmers know that weather is really "king" when it comes to how crop’s yield, many studies have shown that the use of precision farming can increase yield, particularly with the use of GPS based yield monitors. In short, precision farming is the merging of satelite technology with your crop harvest. How? By allowing you to precisely connect your combine's location and harvest results in real time.

There are twenty four satellites above the earth in geo-synchronous orbit providing accurate location coordinates in the form of latitude and longitude. These signals can be picked up by GPS receivers anywhere in the world..

The yield monitor itself records details about your harvest, such as average yield and moisture content. But, If your yield monitor includes a GPS receiver, then the data it records includes your exact position.


With this technology, and some additional software, you can create graphical view of your field that identifes areas of high and low yield and that therefore provides the information you need to make input decisions that can improve economic outcome. For example, you can:

  • Identify areas that require more, or less, chemical attention
  • Determine which hybrid worked best in your particular field.
  • Optimize any practice or input to maximum effieciency

What are the limitations?
Even with today’s technology, such analysis has its limitations – especially when it comes to making decisions. Why? Because the analysis of only one, or even a few fields, provides too small a sample to build statistical confidence. Should I continue using the same hybrid, or not? In some cases, the analysis may result in data that is biased toward favoring a particular hybrid.

Taking precision farming analysis to the next level - online analysis..!
Now there is a way to put even single-field information into a broader context. HarvestMap Systems, Inc. is bringing the power of the Internet to the arena of Precision Farming analysis. HarvestMap will perform the analysis of each yield monitor file completely online. With this approach, a whole new set of benefits can be realized. Not only will you be able to view the yield maps your accustomed to, but you can also receive several additional benefits, such as comparing result against a community of similar fields.

How does it work?
The farmer simply uploads his yield Monitor file to the HarvestMap network after he receives a unique username and password. No one but that user can view the yield map of that field, but the summary of that field becomes part of the HarvestMap community, helping to create a pool of valuable information.

What are the benefits?
There really are two main ones: one; providing users online access to a database that contains yield results from all across North America, and two; incorporating real-time information into the decision-making process, such as commodity pricing – all for a specific field. The value of the "community" data coming from the yield monitor files cannot be overstated.

For example, this information could be used to compare how well your hybrid performed against a whole range of others. Members of the HarvestMap community can ask questions of the database and discover which hybrids performed best, under conditions they specify, or find out how their hybrid of choice ranked in performance against others – regardless of the hybrid type. These searches can be qualified with a set of options, such as:

  • Specify hybrid supplier, or ALL,
  • Specify soil type, or not,
  • Details about the growing season,
  • ... and more.

HarvestMap Systems also plans to perform its own "data mining" of the database and periodically publish results to the site. This report will rank hybrids and chemicals by performance under a variety of conditions. This analysis and raning is unbiased as HartvestMap has no connection with seed, chemical, or other input providers.

The value of the real-time analysis includes computing gross profit based upon your total yield and, the current commodity price of your choice. Taking this further, the company’s tools allow a range of "what-if" scenarios with which the producer can elect to re-compute the yield by substituting his hybrid with other higher-yielding seeds or more efficient chemicals from the HarvestMap database. This substitution option brings the power of "community" data into play, vastly increasing the power of the precision farming concept. Based on the growing historical data, a prediction can be made on your yield increase (albeit a statistical prediction). Users can not only increase their yield, but also their profit – that is the real objective of these tools.

Products: Overview
HarvestMap Systems has launched these new services and they are now availavle. A subscriber to this service can expect to use the following tools:

Your Fields This is the launch point to upload your files and experience our robust error correction algorithms. The "My Fields" feature allows you to see the specifics of each field as well as the composite of all files uploaded. This composite includes yield summaries, as well as the financials. Check back daily to see the financials change as the commodity markets change.
Field Maps This tool enables you to create graphical view of your fields. You can view any of your uploaded files as a yield map, a moisture map, or a hybrid map and view the yield analysis and statistics down to the hybrid level.
Community View With this feature, you can find the highest yielding hybrids by searching the HarvestMap database using criteria of your choice. Use the power of this shared database pool to generate your own reports through unlimited searches.
Financials This tool is your field by field profitability analysis tool. The Financials allows you to monitor your fields online against CBOT closing prices and check the current or future value of your fields on a daily basis. Itemize both direct and indirect costs and track the profitability of your fields as commodity prices change. Generate income statements and more.
What-If Tool

This tool allows you to substitute the highest yielding hybrid in one of your fields based on a search of the HarvestMap Community of data and view the impact to that fields profitability.

This is a very powerful tool to help you with your input decisions.


HarvestMap services are designed to help you optimize your operation by maximizing your Yield and minimizing your cost. By integrating harvest and market data online. With this shared data, we can provide a set of powerful tools to help you optimize your operation.
  HarvestMap makes this community of data available to their subscribers
  ... No software to install
    ...Automatic upgrades to new features
      ...View online, anytime, anywhere

Will farmers be willing to upload their yield monitor files to an Internet site? Can farmers be secure knowing that the details of their file will be kept private? The privacy policy of HarvestMap is to not allow anyone to view a farmer's specific yield data or maps – though the summary statistics will become part of the shared community of knowledge; albeit anonymously. Joe Nelson, President and CEO of HarvestMap Systems, Says, "I believe that farmers will come to realize that the value of their yield monitor files are greatly amplified when it becomes part of a larger community. It is to their benefit to become part of a shared knowledge pool."

Who can use these services?
To become a member of the HarvestMap community, and take advantage of these new services, one needs to subscribe. The price of subscription is divided between an annual fee and a monthly fee. The monthly fee, however, will descrease subscribers upload their yield monitor files. The HarvestMap philosophy is that the fee should be lower for those who participate in this community with their own data.

"This concept pushes the value of precision farming analysis to the next logical level," Nelson says. "Granted, farming is a gamble, and largely dependent upon the weather. But all things being equal, the use of precision farming techniques does provide an edge. By becoming a member of the HarvestMap community," he adds, "farmers can take a quantum leap forward in the realm of precision farming analysis."

Additional services
HarvestMap is offering the error correction feature for two reasons. Several studies have shown that yield monitor files can have errors - some that are inherent to the process, and some that are user related. HarvestMap addresses and corrects such errors, including:

  • Removing the outlier areas,
  • Load name to hybrid name correction,
  • Yield calibration,
  • Combine GPS receiver offset.

This feature obviously benefits the farmer, but it also ensures that the HarvestMap database remains accurate. For more detail about these products, click the following...
