TF Base Map
The TF Base Map shows statistically significant, persistent patterns of relative biomass. The satellite-based TF Base Map is calculated from multi-year satellite data to exclude influences of current weather conditions and different crop types.
This satellite-based TF Base Map:
- shows different site-qualities
- can be used as basis for the creation of application maps
- serves for site-mapping, also in combination with other methods
- allows large-scale analyses at a budget price.
Validation of the TF Base Map
The quality of this product has been proven by several validations. Validation of our measurement methods has been done via direct comparison with other widely recognized methods like e.g. the German Reichsbodenschätzung, EM38 electrical conductivity measurements or yield maps from combine harvesters.
On the image below you see on the left side the calculated persistent relative fertility, the satellite-based TF Base Map. The next two images show the results of the farm soil map and the EM38 electrical conductivity measurements. The patterns calculated by our considerably cheaper method widely match the two other measurement methods, without having to buy extensive data sets or having to conduct own measurements on the fields.

Currently, we offer the processing of data for fields with a size of 2 ha and above. The minimum order size is 200 ha. In case you order less, the price for 200 ha will be charged. The surcharge can be reimbursed with later orders.
Should processing of parts of this area not be possible, then these areas will not be taken into account in the cost calculation.
Thus, you will only pay for the areas for which we can deliver our products.
For 5 €/ha excl. VAT you get the following products if you order the service:
| Product name | Description | Price in €/ha (only analyzed data) |
Unit | Output format |
|---|---|---|---|---|
| TF Base Map | Shows the persistent relative fertility | 5 € excl. VAT | % | TF-XML, Point-Shape-Files |
The delivery of the TF Base Map includes:
- TF Base Map showing the persistent relative fertility
- Spatial resolution in a fixed raster cell size of 20 x 20m
- Delivery in an Agrar Office-compatible format or as point-shape file which can be read by the most prevalent agricultural software packages which include GIS functionality.
Upon receipt of an order we require the boundaries of the ordered fields as well as of the environmental protection zones, preferably in TF-XML-format.
Please also note our attractive package deal:
- TF Base Map & TF Zone Map for only 6€/ha excl. VAT!
TF Zone Map
Besides the TF Base Map there is the possibility to receive the TF Zone Map, which can be used as a base for soil sampling.
The TF Zone Map allows:
- The optimization of your soil probing strategy for an improved soil database
- The reduction of the number of laboratory probes and resp. costs
The example below shows the TF Base Map, which results from the spectral analysis of the satellite images, overlaid with the TF Zone Map.

Areas of similar values in the TF Base Map are merged into one zone in the TF Zone Map.
These zones enable you to conduct a cost-saving soil probing which well represents the range of soil characteristics on your field.
You decide on the average size of the zones. Thus, the TF Zone Map can be adapted exactly to your needs.
Currently, we offer the processing of data for fields with a size of 2 ha and above. The minimum order size is 200 ha. In case you order less, the price for 200 ha will be charged. The surcharge can be reimbursed with later orders.
Should processing of parts of this area not be possible, then these areas will not be taken into account in the cost calculation. Thus, you will only pay for the areas for which we can deliver our products.
For 4€/ha you get the following products if you order the service:
| Product name | Description | Price in €/ha (only analyzed data) |
Output format | |
|---|---|---|---|---|
| TF Zone Map | Zones for optimized soil probing | 4 € excl. VAT | TF-XML, Polygon-Shape-Files |
The delivery of the TF Zone Map includes:
- The digital TF Zone Map with zone extent and zone number
- Zones in designated average zone size by definition of the minimal and maximal zone size during the ordering process
- Delivery in an Agrar Office-compatible format or as point-shape file which can be read by the most prevalent agricultural software packages which include GIS functionality.
Upon receipt of an order we require the boundaries of the ordered fields as well as of the environmental protection zones, preferably in TF-XML- format.
Please also note our attractive package deal:
- TF Base Map & TF Zone Map for only 6€/ha (excl. VAT!)
Additionally, we can of course offer you the matching agricultural software which allows you to import this data and process it e.g. into application maps. You can find further information
