Recording shape files in ODK

Hi all

We are starting a new CMRV project in Acre, Brazil (Building on our CMRV
project in Guyana) and one of the main criteria now is to record is area
size. ie new forest farm plots etc. I remember a while ago there was a beta
version of ODK that I tested that incorporated the functionality of the
separate "distance and area" app, embedded into an ODK form. Just wondering
if this has progressed any further of if anyone else has a good solution
for capturing shape data (by walking with the phone around the area to
record).

We have used the "distance and area" app in Guyana for this task but found
it unreliable in saving data, and also then complicated in managing the
individual shape files it creates, having to bring then into a GIS package
to visualise. It is also not a good solution as meta data cant be
associated to the shape file to identify for example land use etc.

Is anyone else doing a similar thing and have any good solutions - would
love to hear.

Thanks

Jon

Jon,

There was talk about this sort of widget a few years ago
(https://groups.google.com/forum/#!msg/opendatakit/vIpPH5dcYcc/TFXTPqEe78IJ)
but the folks who were working on that version haven't touched the
code in a year and a half
(https://bitbucket.org/aostiles/odk-collect-afsis/commits/all). One
good first step is to email those developers and see what their status
is.

Hi all,

Interesting conversation here but noticed that much of the dialogue on capturing shape data, geo-tracing, etc has gone dormant for awhile.

I'm currently working on a project that would benefit from tracing field perimeters, calculating surface area, etc. and I am curious if a widget or the necessary code in xlsform has been completed.

Fyi...don't have much experience with programming. Thanks!

Hi Jon,

If you use the Smap server it will interpret a repeating group whose name
starts with geopolygon as collecting points for a polygon. The same goes
for repeating groups whose name starts with geolinestring, these are
interpreted as linestrings. These are stored as geometries in a Postgis
database so it would be trivia to extract shape files.

If you are interested there is more about the Smap server in the
organisational blog http://blog.smap.com.au/ and you can download the
server from https://code.google.com/p/smap-suite/

regards

Neil

In SurveyCTO, we have functions to calculate the area enclosed by a series
of repeated geopoints or to calculate the distance between two geopoints.
We have not yet implemented the new data types, however, as it seemed easy
enough to take any two fields or any repeated fields as inputs, without the
need for new types.

There is a recent discussion on adding new data types to ODK, spearheaded
by Enketo's Martijn. You can find it here:

Interesting, looks like its simply an ODK form up front and then the smap
system does the rest

but can I still use my own ODK engine to collect data in fusion, then
export it and import it into smap for the points to be made into strigs -
then i presume can be exported out as a normal GIS file format

the 40+ crew in Guyana, and now a further 40 in Acre, are all trained in
ODK and fusion etc, together with maps engine for visualisation, and we
also have some skills in ARC info - so keen not to introduce a whole new
system as will just add to the already confusing array of systems and
skills needed.

But interested to hear more.

Thanks

Jon

It does sound like changing server will impact your project.

Yes it is just a standard ODK form and you can use odkCollect in the field.

Putting the data in aggregate then fusion first followed by sending it to
the Smap server does sound complicated. As long as you can submit the forms
to both systems I guess it should work.

Smap doesn't' have a direct link to fusion but you can export as XLS and
then import to fusion. On export you can specify which forms to include so
you can exclude the repeats that hold the point data.

Arc Info should be able to connect directly to postgis.

There may be a way of getting shape files from aggregate / fusion using the
same approach as Smap. Ie just a repeating group of locations.

Neil

Hi,

Smap Server stores repeated geopoints as a polygon or linestring in postgis
if the name of the repeating group starts with geopolygon or geolinestring.
Smap also supports the geoshape and geotrace datatypes and again stores
those as geometries in Postgis.

You can exports the results as shape files, this video shows how to do this
although the data was actually points in the video.

You can download Smap server from http://www.smap.com.au/downloads.shtml
