Thanks , bouteloua and Colin Meutk
I workaround by create a project and an add two fields.
Field add : field:height in cm., field:status (a,b,c,d,e,f or l)
When I use through Smart Phone after I take a picture , I go to add to project and update data of height in cm. and status so I can get data from Smart Phone . When I use export function , I can choose two more fields and export in CVS format.
We start to seedling Shorea roxburghii this year , and will grow at Maetamund Forest by June 2019.
This is an prototype phase of how to collect data.
But I have another issue of language after export in CVS format, the font code do not match in Thai language.
Thanks
