How to add exported Polygons ( to QGIS from Geoshape)

[luna_ricky_tavi]

Hello Everyone!

I am having troubles with exporting Polygons made by ODK Collect. I made them with Geoshape and and the coordinates are saved in one column, but I just dont find no way to create polygons in QGIS.
In QGIS I created points from the table with the latitude and longitude which is the position of the surveyed points. But what I need is also the polygon, which was drawn by the user with the geoshape option.

Here the exported file (see shape example):
dimbokro.csv (1.3 KB)

Thanks in advance !

Hi @luna_ricky_tavi ,

You should take a look at this showcase to add a question to your form that calculates the WKT of your geometry. Then you will be able to open your csv with QGIS and then specify the WKT column :

ODK geoshape/geotrace/geopoint to WKT

After kml export by @Xiphware and geojson export by @detrygeoffroy, I simply adapted @Xiphware example forms to generate wkt (point, linestring, polygon) from geopoint, geotrace and geoshape odk fields. In opposition to geojson and kml, WKT does only describes the geometry, it does not contains any attribute value. [odk_to_wkt] So you can collect data and open exported CSV within QGIS with "delimited text layer" tool, choose the column which store wkt, select the projection (4326) and show y…
