|
"process": { "dataset": [ "file.added"]}, |
### dependencies
a list of packages the extractor depends upon
| Code Block |
|---|
|
"dependencies": [
"imagemagick",
"ufraw-batch"
], |
### parameters
Allows parameters to be passed to extractor upon submission
| Code Block |
|---|
|
"parameters":{
"schema": {
"fields": {
"type": "string",
"title": "Naming Fields",
"default": "None"
}},
"form": [
{
"key": "fields",
"notitle":false}]
}, |

"parameters": {
"schema": {
"orthophoto_resolution": {
"type": "string",
"title": "Quality",
"enum": [
"2",
"5",
"10"
],
"default": "5"
},
"fast-orthophoto": {
"type": "boolean",
"title": "Use sparse reconstruction (fast orthophoto)",
"default": true
}
},
"form": [
{
"key": "orthophoto_resolution",
"type": "select",
"notitle": true,
"titleMap": {
"2": "High Quality",
"5": "Medium Quality",
"10": "Low Quality"
}
},
