###### Transform shape to geotiff ###### Transform shape to geotiff
The VRAHerbicide task only processes tiff items as input. The VRAHerbicide task only processes tiff items as input.
If your input data is a processed shape file it first needs to be converted to geotiff, this can be done with the 'ShapeToGeoTiffTask'. If your input data is a processed shape file it first needs to be converted to geotiff, this can be done with the 'ShapeToGeoTiffTask'.
Pass the code of the shape item into the {code} parameter, this creates a new item with tiff data as the parent of the shape item. Pass the code of the shape item into the {code} parameter, this creates a new item with tiff data as the parent of the shape item.
This new geotiff item should be used as input to the a task. This new geotiff item should be used as input to the a task.

Use the input map code inside {itemCode}, specifying an inputCode for the input data item. Use the input map code inside {itemCode}, specifying an inputCode for the input data item.
{itemCode} needs the code of the data input item passed into it. {itemCode} needs the code of the data input item passed into it.
An **optional** {extraItemCode} can be passed inside the 'extraInputcode' field to process herbicide from 2 inputs. An **optional** {extraItemCode} can be passed inside the 'extraInputcode' field to process herbicide from 2 inputs.

##### Create taskmap ##### Optional input parameters #####
[Create Taskmap](Create-Taskmap.md) There are some optional task attribute input parameters for greater flexibility.
##### Download the data * **inputLayerName**
In case the data is available it can be downloaded with the items API. Allows you to specify which layer to use for an input item.
> Request * **extraInputLayerName**
```javascript Allows you to specify which layer to use for the extra input item.
GET /api/v1/items/{itemcode}/download * **minPercentile** value between 0.0 - 1.0
Allows you to specify the minimum percentile value to 'filter' lower bound input data
* **maxPercentile** value between 0.0 - 1.0
Allows you to specify the maximum percentile value to 'filter' upperbound bound input data
* **plantingDate** if relevant
Allows you to specify the date the crop is planted.
* **measurementDate** if relevant
allows you to specify the date when the measurements were taken.
Default input layer name for herbicide is the agent inputType used (lutum, om).
Default percentile values for herbicide are 0.0 and 1.0.
Default dates are 'inherited' from the cropfield item passed to the task.

{
"inputLayerName": "customLayerName",
