+## 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. !~**

+* geojson is expected in WGS84, 4326 projection.
+* endPoint is optional but angle or endPoint is needed!

+##### 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.
