## VRANbs API v0.3
|
|
[<< Home](README.md)
|
|
|
|
FarmMaps is an asynchronous architecture, the API flow keeps this in mind.
|
|
The API expects that all data is already processed and available provided, for example through the normal FarmMaps flow (frontend).
|
|
|
|
For the currently available public FarmMaps API you can take a look at swagger: http://farmmaps.awtest.nl/swagger/index.html
|
|
|
|
**Limitations**
|
|
* Currently VRANbs only accepts input tiffs in WGS84/EPSG4326
|
|
* Data isn't automatically deleted as farmmaps has no support for this.
|
|
* But API users can delete their own items through the farmmaps API.
|
|
|
|
**Input preperation**
|
|
* Users can upload their own data if needed. (in case of when FarmMaps has not processed the required data).
|
|
* The farmmaps file API can be used for this.
|
|
|
|
**Users can poll the task api to see if a task is completed**
|
|
**This can be achieved with the task execution id obtained from calling the 'ItemTask' API.**
|
|
[Poll task status](Polling-task-status.md)
|
|
|
|
**Users can query the API for child items of a cropfield to see what items it has.**
|
|
|
|
### API flow
|
|
* Authenticate User
|
|
* Optional steps
|
|
* *Create cropfield through FarmMaps API*
|
|
* Item 'vnd.farmmaps.itemtype.cropfield' must be created with its data as specified in the api.
|
|
* Task 'vnd.farmmaps.task.workflow' needs to be executed to aggregate all needed data.
|
|
* This is an asynchronous process and can take a while before all data is collected in FarmMaps.
|
|
* *Upload own data*
|
|
* IF shape data, convert to geotiff.
|
|
* *Create 'vnd.farmmaps.itemtype.user.input' item for targetn calculation.*
|
|
* *Task 'vnd.farmmaps.task.vranbs' can be executed with the 'targetn' operation*
|
|
* *Task 'vnd.farmmaps.task.vranbs' can be executed with 'uptake' operation* to create an nitrogen uptake map.
|
|
* Task 'vnd.farmmaps.task.vranbs' must be executed with 'nitrogen' operation to create an appliance map.
|
|
* Task 'vnd.farmmaps.task.taskmap' can be executed to create a taskmap.
|
|
* Download item data (tiff of shape)
|
|

### Steps
|
|
[Authentication](Authentication.md)
|
|
|
|
##### Optional
|
|
[Create Cropfield](Create-Cropfield.md)
|
|
[Upload Data](Upload-Data.md)
|
|
|
|
###### Transform shape to geotiff
|
|
The VRANbs 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'.
|
|
|
|
Pass the code of the shape item into the {code} parameter, this creates a new item with tiff data as a sibling of the shape item with the same parent.
|
|
This new geotiff item should be used as input to the vranbs task.

##### Using VRA Nitrogen fertilization task
|
|
The VraNbs task currently supports 3 operations:
|
|
* **targetn** - calculates the target nitrogen based on target yield.
|
|
* **uptake** - creates the nitrogen uptake map.
|
|
* **application** - creates the nitrogen fertilization application map.
|
|
|
|
###### targetn operation
|
|
Create a 'vnd.farmmaps.itemtype.user.input' item to use in this operation.
|
|
(step not needed if you already know the target nitrogen you want to work with.)
|
|
The user.input item must parent the '{user_code}:USER_IN' item and can be obtained by calling following request:
|
|

###### Uptake map operation
|
|
Execute the VRANbsTask with the item code of the cropfield as parameter inside {code}.
|
|
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. ex. uploaded isaria/data data.
|
|
The resulting nitrogen uptake map will be created as a child item under the cropfield item (this can be queried).

##### 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.
|
|
* **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
|
|
|
|
Default percentile values for nbs are 0.0 and 1.0.
|
|
|
|
```javascript
|
|
{
|
|
"inputLayerName": "customLayerName",
|
|
"minPercentile": "0.1",
