## VRAHaulmkilling API
|
|
[<< 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: https://test.farmmaps.eu/swagger
|
|
|
|
**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' can be executed if needed 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.
|
|
* Querying predefined haulmkilling agents (to use as input for the task).
|
|
* Task 'vnd.farmmaps.task.vrahaulmkilling' must be executed to create an application 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 VRAHaulmkilling 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 a task.

POST /api/v1/items/{code}/tasks
|
|
{
|
|
"taskType": "vnd.farmmaps.task.shapetogeotiff"
|
|
}

"taskType": "vnd.farmmaps.task.shapetogeotiff"
|
|
}
|
|
```
|

|
|
Response 400 Tasktype not found
|
|
Response 401 Not authenticated
|
|
Response 403 No WRITE permissions in item
|
|
Response 404 Item not found
|
|
|
|
###### Querying predefined haulmkilling agents.
|
|
A list of haulmkilling agents can be requested by getting the "vnd.farmmaps.itemtype.codelist.fm005" items from farmmaps.
|
|
> Request
|
|
```javascript
|
|
GET /api/v1/items/?it=vnd.farmmaps.itemtype.codelist.fm005
|
|
```
|
|
> Response 201
|
|
```javascript
|
|
[
|
|
{
|
|
"code": "....",
|
|
// ....
|
|
"data":
|
|
{
|
|
"cl": "vnd.farmmaps.itemtype.codelist.ctgb",
|
|
"code": "9326",
|
|
"label": "quickdown",
|
|
"options": "risk.standard,risk.high"
|
|
}
|
|
},
|
|
...
|
|
]
|
|
```
|
|
|
|
Response 400 Itemtype not found
|
|
Response 401 Not authenticated
|
|
Response 403 No READ permissions in item
|
|
Response 404 Items not found
|
|
|
|
An item's data property contains a single haulmkilling agent with its crop protection agent code in farmmaps.
|
|
To get additional information for a crop protection agent you can query farmmaps for the "vnd.farmmaps.itemtype.codelist.ctgb" itemtype and with a datafilter with the code specified in the haulmkilling agent item's data property as above.
|
|
|
|
###### Creating an application map with the VRAHaulmkilling task
|
|
Execute the task with the item code of the cropfield as parameter inside {code}.
|
|
Use the code of the input item inside {itemCode}, this specifies an item to use as input.
|
|
|
|
The resulting application map will be created as a child item of the cropfield item (this item can be queried).
|
|

**'inputCode'**
|
|
**'agentCode'** needs to have a value that is gotten from the haulmkilling agent query. This is not an item code!!!
|
|
**'inputType'** "wdvi" or "ndvi"
|
|
**'selectedOption'** needs to have a value that is gotten from the haulmkilling agent query.
|
|
|
|
##### 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
|
|
* **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 Haulmkilling is the agent inputType used (wdvi, ndvi).
|
|
Default percentile values for Haulmkilling are 0.05 and 0.90.
|
|
Default dates are 'inherited' from the cropfield item passed to the task.
|
|
|
|
```javascript
|
|
