Dear all,
I have searched on this forum for a while, but I can't find any concrete
answer regarding the possibility to preload GPS point data in ODK collect.
I would like to load GPS point data in ODK collect so that the field worker
can visit this point for a measurement. Is this already possible in ODK
collect? Or only in ODK Tables? Thanks for providing clarity!
Kind regards,
Eddy
You can use preloaded data ---
https://opendatakit.org/help/form-design/data-preloading/
And then convert the string values to numeric values.
But there is no widget that reports the distance and bearing to that
geopoint (and that periodically updates that information).
You would need to create an external app that did that.

I have exactly the same problem. I would like to preload Geopoint from my data base. And use Map Data in GeoODK Collect application on the field in order to update related waypoints data and send back updated forms in Aggegate.
And honestly, I don't see how I can use data-preloading since Geopoint are a combination of two fields (Latitude and Longitude) and it's only one row in XLSForm. I'm not a programmer, but it must be a simple way to upload Geopoints in a form.
Dear all,
Thank you all for your ingenious input and thoughts. But I still have a question regarding preloading geopoints and GeoODk.
I have managed to preload GPS points and related information (tree information and location) inside of a repeat group. In total there are 442 groups, each with its respected geopoint. However, when I try to view the group of points inside of GeoODK, I only see one point. (probably averaged? Or probably only shows the first group... I don't really know what happened)
Is there a way to view all 442 points at once on the GeoODK map or is it just too much to ask for the program?
Kind regards,

Geopoints are stored as 4 space-separated values:
lat long alt acc
Where altitude and accuracy are measured in meters.
If your external table contains a column with a string of this form, then
you can have a calculate geopoint field that uses the value from that
column (or from a string field that contains the contents from that column).

Stephan,
Probably best to ask the GeoODK team...

Hi M. Sundt,
Thank you so much for your precious time and knowledge. It's helping me a
lot!
I've been able to preload position. Nevertheless, it's not exactly what I
want at the end.
What I would like to do is being able to update informations that I already
got by clicking on it using the data position icon using Map Data via
GeoODK. As a example, I would like the man on the field looks where he is
on the map, go to the nearest position dot on the map, click on it, updates
form's infos, send infos to Aggragate... and maybe (if possible) change the
position dot's color after sending information in order to visually see the
this one is done.
Best regard!
Alexandre

This review-and-update behavior is not what the ODK 1.x tools were designed
for; that is what the ODK 2.0 tools (when they are repeased) will support.
You should look at other tools built on top of ODK, such as SurveyCTO (or
GeoODK) to see if they have extensions that handle your needs.

This behavior isn't currently in SurveyCTO. We support pre-loading GPS
coordinates for purposes of, for example, calculating the distance between
a current location and a location captured in a previous visit. And our
dataset functionality allows you to stream incoming data from one form --
including GPS coordinates -- into the pre-loaded data of another form (as
when you have a listing survey feeding into a baseline or a baseline
feeding into a midline). But we don't have any option to pop a preloaded
location into a map view. Certainly if enough SurveyCTO users wanted that
we would add it; and if somebody wanted it badly enough to subsidize it,
then we could add it pretty quickly.
Best,
Chris

Hi Marshall,
I'm not aware of any existing function to check whether one point is within
the area defined by a series of other points. Certainly it would be
possible to add such a thing, but, as with everything, it's a question of
who covers the cost of that. This is the first time I've heard such a
request.
Best,
Chris

Thanks Chris. I figured out a work-around, extracting the latitude and
longitude by calculating:
selected-at(string(${blah}),0) [for latitude]
selected-at(string(${blah}),1) [for lon]
