The following 9 attribute fields can't be directly edited like the other fields. WallsMap will fill them automatically when appropriate. The location and timestamp fields have specific names ending in an underscore, which tells WallsMap to treat them in a special way. They can also be useful in non-TSS projects, although other GIS programs will treat them as ordinary fields. The TSSID field, on the other hand, is a normal field that has been set read-only and identified as the key field in the shapefile's template component. For newly-added records the TSSID field will remain blank until the data manager uses the Compare with Other Layers function to create a new database snapshot. Once assigned, the TSSID will not be reused, even if the record is eventually deleted.
TSSID
|
Tooltip:
|
Unique TSS identifier assigned separately, blank for new shapefile records
|
|
Type:
|
7 chars (3-letter county abbreviation followed by 4 digits)
|
|
Notes:
|
Can also be blank if the feature is new, in which case a TSSID is assigned automatically
when the updated shapefile is processed. At least this field should be included in shapefiles prepared to satisfy data requests.
|
CREATED_
|
Tooltip:
|
UTC timestamp with editor's name, filled automatically when a new record is saved
|
|
Type:
|
45 chars
|
|
Notes:
|
Formatted as "yyyy-mm-dd hh:mm:ss name"
WallsMap prompts for the name if one hasn't been established for the session or saved as a program setting on the computer. Many records have "TSS-Export" as the editor's name since they were established prior to July 2009 when timestamping was fully implemented.
|
UPDATED_
|
Tooltip:
|
UTC timestamp with editor's name, filled automatically when either a new record or an edited record is saved
|
|

As for the CREATED_ field, WallsMap prompts for the name if one hasn't been established.
