If you cannot upload these files then it limits the capabilities of the forms
Correct. Presently Kobo doesnt accept uploading geojson files (we hope to add this soon). In the mean time, if you are desperate you can convert your geojson data to an equivalent CSV for the purpose of using it for geo-based selection options.
For example, this is the default cities.geojson
file used in the ODK all-question-types.xlsx form:
{
"type": "FeatureCollection",
"features": [
{
"type": "Feature",
"properties": {
"title": "Warsaw",
"info": "Capital city of Poland",
"id": "1"
},
"geometry": {
"type": "Point",
"coordinates": [
21.0122,
52.2297
]
}
},
{
"type": "Feature",
"properties": {
"title": "Berlin",
"info": "Capital city of Germany",
"id": "2"
},
"geometry": {
"type": "Point",
"coordinates": [
13.4050,
52.5200
]
}
},
{
"type": "Feature",
"properties": {
"title": "Paris",
"info": "Capital city of France",
"id": "3"
},
"geometry": {
"type": "Point",
"coordinates": [
2.3522,
48.8566
]
}
},
{
"type": "Feature",
"properties": {
"title": "Kyiv",
"info": "Capital city of Ukraine",
"id": "4"
},
"geometry": {
"type": "Point",
"coordinates": [
30.5234,
50.4501
]
}
}
]
}
Converted to an ostensibly equivalent CSV is:
name,label,geometry
1,Warsaw,52.2297 21.0122 0 0
2,Berlin,52.5200 13.4050 0 0
3,Paris,48.8566 2.3522 0 0
4,Kyiv,50.4501 30.5234 0 0
which you can then upload as media to use in a select_one_from_file or select_mutliple_from_file
