[Talk-us-massachusetts] automated edits and massgis tags

[Mateusz Konieczny]

I started now more thorough analysis of tags considered for deletion.

Jason's keep list (so tags on this list will not be deleted)

massgis:WETCODE
massgis:SITE_NAME
massgis:ref
massgis:school_id

I am not 100% sure that following should be removed so I will not touch
them:

attribution="Office of Geographic and Environmental Information
(MassGIS)" source=massgis_import_*
massgis:SOURCE

There are some tags where after value analysis and consulting database
documentation I am not sure whatever deletion is the best solution:

massgis:PUB_ACCESS - massgis:PUB_ACCESS=Y and massgis:PUB_ACCESS=N are
usable for editors and these dominate values. It may be worth removing
if access=* is tagged but I will leave it for separate edit.

massgis:PRIM_PURP - potentially convertible to protect_class
https://wiki.openstreetmap.org/wiki/Tag:boundary%3Dprotected_area#Classification

massgis:MANAGER - 'Manager of the property (only if different from
FEE_OWNER).' - potentially retag as operator?

massgis:schoolid - retag to massgis:school_id?

massgis:COMMENTS - requires manual review to check whatever it is worth
keeping

massgis:IT_VALDESC - human readable description, some values are
popular. May be removed if description duplicates OSM tags, but I
prefer to do it as a separate edit to reduce complexity

massgis:ALT_SITE_N - potentially convertible to alt_name

I located documentation for database keys - it is available at
http://www.mass.gov/anf/docs/itd/services/massgis/os-schema.pdf

After analysis I consider following tags as candidates for deletion and
plan on deleting them:

massgis:FEE_OWNER - Owner or grantor of the land represented by the
polygon' so not convertible to OSM tags without research that is not
worth the effort

massgis:TOWN_ID - 99% are numbers, other cases are ;-separated numbers,
it is basically is_in in special format so not worth keeping

massgis:OWNER_TYPE - one letter codes, useless without documentation

massgis:FEESYM - codes, useless without documentation

massgis:EOEAINVOLV - mysterious and bizarre, useless without
documentation

massgis:FY_FUNDING - funding date (?), useless if that guess is true,
useless without documentation

massgis:ATT_DATE', 'Date attributes were last modifed.' - useless
metadata from external database

massgis:LEV_PROT - 'Code for the level of protection given to the
land.' - with values: perpetuity (P), term limited (T), limited (L). I
see no value here.

massgis:DEED_ACRES - area is provided by geometry itself in OSM

massgis:OS_DEED_BO - 'The book that the deed was recorded in on
CAL_DATE_REC.' - useless

massgis:OS_DEED_PA - 'The page of OS_DEED_BOOK that the deed was
recorded in.' - useless

massgis:ASSESS_ACR - 'Acreage of polygon according to local assessor.',
again OSM stores area in geometry itself

massgis:SHAPE_AREA - numbers that probably represent area of feature
what is not useful in OSM

massgis:ACRES - numbers that probably represent area of feature what is
not useful in OSM

massgis:OS_ID -  'Unique ID for feature class ([TOWN_ID]-[POLY_ID]).' -
useless

massgis:OWNER_ABRV -  'Abbreviation of FEE_OWNER kept in OSNAMES
table.' - useless

massgis:SOURCE_MAP -  'Source map used to enter linework/attributes.' -
useless

massgis:ASSESS_MAP -  'Local Assessor’s Map.' - useless

massgis:ASSESS_LOT -  'Local Assessor’s Lot.' - useless

massgis:BASE_MAP -  'Recompilation map name/type.' - useless

There are still many tags that wait for review - I posted message now
to avoid making it too long.
