The Villages Road and Address Import
See https://wiki.openstreetmap.org/wiki/The_Villages_Road_and_Address_Import
Instructions
- Open the original data in QGIS
- Format OSM fields with QGIS functions to have proper capitalization and full spellings without extraneous whitespace, based on original fields. For example OSM uses names like North Main Street, not N MAIN ST. All fields are of the QGIS type "text" even if they're numbers.
- You can use the Attribute Table's Field Calculator for this; you can copy-paste the
qgis-functions.py
file into the Function Editor and then use the Expression tab to create new, formatted virtual fields. Don't worry if the field name limit is too short, it can be fixed in JOSM.
- You can use the Attribute Table's Field Calculator for this; you can copy-paste the
- For addresses:
- The Addresses shapefile is recorded in the ESRI:102659 CRS, you may need to convert or reproject to/from.
ADD_NUM
becomes the virtualaddr:housenumber
(oraddr:house
temporarily, avoiding addr:house which is a real tag)"UNIT"+"LOT"
becomes the virtualaddr:unit
(sometimes the LOT key is used for multiple units in a range)SADD
becomes the virtualaddr:street
(oraddr:stree
temporarily) via thegetformattedstreetnamefromaddress("SADD")
custom expressionPOST_COMM
becomes the virualaddr:city
via thetitle("POST_COMM")
expression (we care about postal community addresses not what municipality a place might be governed by)POST_CODE
becomesaddr:postcode
(oraddr:postc
temporarily)
- For roads:
NAME
becomes the virtualname

- Use the Filter with Form function to Select all entries with
"LIFECYCLE"='Current'
- Export to Geojson, only exporting selected entries, selecting only the OSM-formatted fields we want.
- Ensure the export file is in the
EPSG:4326 - WGS84
CRS. - Open in JSOM. It's suggested to begin with roads first, addresses second, so the addresses can be placed in context.
- In the Roads dataset, select and remove all relations from the geojson/shapefile layer: the data often has one relation per road and this is improper for OSM import.
- Select a small region to work on: one neighborhood or smaller. For this import, we are assuming that only newly-constructed small residential areas will be imported, not main roads or commercial areas or areas with significant existing map data.
- Download the area you're working on from OSM, into a new Data Layer (not your geojson layer.)
- Select all features to be imported at this time and leave them selected until the merge step below.
- Select all ways for roads, or all nodes for addresses. Make sure you aren't about to mass-edit the nodes of a road: deselect the nodes if this happens.
- Ensure the tags are correct and good. (QGIS has a character limit and sometimes doesn't like colons, so double check that
addr:house
isaddr:housenumber
,addr:postc
isaddr:postcode
,addr:stree
isaddr:street
, etc.) - Mass-add new tags like
highway=residential
,surface=asphalt
, etc, as indicated. - Remove any spurious tags that may have been brought over in the import (if it's not in the OSM Wiki, we don't want it.)
- Press ctrl-shift-M to merge into the OSM data layer. There will be a warning, but click OK; we will be extra careful about validating the merge in the next steps.
- For addresses, remove any address nodes that seem to not reflect reality or be placed far from the street bearing their name: it's better to not have 123 Adams Street mapped at all, than to claim that 123 Adams Street is hovering over someone's newly-built house at 321 Franklin Avenue, 200 feet away from Adams Street. (Cities often won't remove old addresses, leading to confusion when new streets are built.)
- For roads, highlight multiple street segments which have the same name and press C to combine them: the county data has one way per road segment and that's excessive for OSM.
- Check the edges of the imported areas to ensure new roads are merged with any preexisting roads
- Check the import area to ensure no incorrect overlaps
- Use the JOSM validator to ensure no errors in imported data. Warnings about existing data separate from the import can be ignored.
- If there are duplicate house numbers in the data, investigate and remove the more-unlikely node or both nodes. For example
4650 Ramsell Road
is duplicated in the source data, but the easternmost copy is on the "odd" side of the street and between 4653 and 4663 so it's more likely to actually be 4651, 4655, 4657, 4659, or 4661. We have no way of knowing, so we can either delete it entirely or simply delete the housenumber tag and leave it as an address without a number for a future editor to review. (We may submit incomplete data, just not wrong data.) We then leave the westernmost copy alone since 4650 fits neatly in between 4640/4644 and 4654/4660. - All known duplicates:
- 4886 C 472 (one is a daycare the other is a church)
- 5626 C THOMAS RD has unit numbers in the original data's Notes field
- 301 CURRY ST
- 401 HALL ST
- 340 HEALD WAY has many buildings and many units per building, in the notes
- 1908 LAUREL MANOR DR (one is a CELL TOWER)
- 1950 LAUREL MANOR DR (each one has multiple units in a range, in the notes)
- 6217 MEGGISON RD (one's note is "restroom/storage")
- 6221 MEGGISON RD (one's note is "pavilion")
- 6227 MEGGISON RD (one's note is "recreation center")
- 102 NE 4TH AVE (one is a cell tower, the other a water tower)
- 11750 NE 62ND TER (one's note is Pebble Springs retirement community building)
- 13813 NE 136TH LOOP UNIT 1306
- 8550 NE 138TH LN (each is a different building number)
- 4650 RAMSELL RD
- 400 RUTLAND ST (both say "church owned")
- 308 SHAWN AVE (one says Wildwood Acres, the other Progress Energy Pump 29)
- 413 S PINE ST
- 2605 TRILLIUM RDG (one says bldg 1, the other says meter)
- 2680 TRILLIUM RDG (bldg 3, meter, meter)
- 13940 US 441 (different building names in the notes)
- 702 WEBSTER ST (one is city of ww, the other retention pond)
- If there are duplicate house numbers in the data, investigate and remove the more-unlikely node or both nodes. For example
- Click upload
- Make sure there are no erroneous Relations or other unwanted objects about to be uploaded.
- Use a descriptive changeset message like "Roads/Addresses in The Villages #villagesimport"
- Set the Source to be "Sumter County GIS"
- You can easily copy-paste the below into the Settings tab:
comment=Roads/Addresses in The Villages #villagesimport
import=yes
website=https://wiki.openstreetmap.org/wiki/The_Villages_Road_and_Address_Import
source=Sumter County GIS
source:url=https://gitlab.com/zyphlar/the-villages-import
- Review imported data in Achavi or Osmcha to ensure it looks proper.
