[Talk-in] Small Import of tree tags in Botanical Garden, Mumbai, India

[Milind Oka]

Thanks to all of you for your encouragement.  I am accepting all of your
suggestions, they are indeed complementary to each other.
I will divide the list into three non overlapping sets - 1) the  rare tree
set (around 220 trees) 2)  multiple occurrences of these trees (around 1200
trees) 3)  remaining trees.
Will also divide them further into smaller chunks for convenience and
upload them in stages, Will post the progress regularly in this list and on
openstreetmap-india telegram group. Also will try to do some osm diary
entries.  I will be happy to take help from you whenever required.

At present I have created a few  ods (calc)  files and still working on
them. For example local name should be in native script. this column is
totally  missing in the original list.

My typical entry for merge-upload is like this

natural name species
name:mr latitude longitude
tree Earleaf Acacia Acacia auriculiformis Australian Acacia ऑस्ट्रेलियन
बाभूळ 18.97841124 72.8372430217
tree Baobab Tree Adansonia digitata Gorakh Chinch गोरख चिंच 18.9786334403
72.8351334761

The column without title will not be read by JOSM but I have kept it for
reference.

I have not done any import before. Initially it seemed very difficult to me
but a JOSM import tutorial  at
https://learnosm.org/en/josm/opendata-plugin/  is very helpful and gave me
some confidence. Little confusing is the final merge command. You need to
make import-tag layer active
(and then target the OSM layer in the following popup). If OSM layer is
active, merge command is disabled.

I opened these tag lists number of times and merged them as trial (but of
course not uploaded, I turn off wifi during trials).
The upload dialog showed that only merged tree tags as new edits. The merge
dry run seems to be perfect.

Will try the actual import in couple of days. My friends Tayyab and Pralhad
and Vishwas are also participating. This will definitely speed up the work.
Thanks to them too.

Regards
Milind
