## Create taskmap
The user can use the "ItemTask" API to execute the TaskmapTask with the cropfield item code in {code}.  
{itemCode} should contain the item with tiff data.

**~! REMEMBER, creating a taskmap with a high resolution < 1 can take a considerable time (from minutes up to hours). !~**  
**~! It helps to lower the precision to say 1 or 0 if a high resolution is needed. !~**

This will create the item with shape data as a sibling of the input item.

##### Optional input parameters #####
There are some optional task attribute input parameters for greater flexibility.

* **inputLayerName**  
Allows you to specify which layer to use for an input item.
* **precision** default value of 2 decimals.
Caps the values to {precision} decimals after the .
* **endPoint** geojson geometry. (endpoint or angle is needed!)
point geometry
* **angle** value between 0.0 - 360.0. (endpoint or angle is needed!)
Orientation of the taskmap fishnet.
* **centered** true or false.
centers the abline in the middle of the 'cellWidth' axis.

Default percentile values for nbs are 0.0 and 1.0.   

```javascript
{
    "inputLayerName": "customLayerName",
    "precision": 2,
    "angle": 45,
    "centered": "true",
    "endPoint": "{
		\"type\": \"Point\",
		\"coordinates\": [6.014997043859679, 53.090253715796308]
    }"
}
```

**Endpoint and startpoint are strings! not json!**
