What is this? Is this part of "Ward Map" or is this something apart, on another application?
The operative words here are "local government" - your state/city/county. Perhaps for such things as property tax assessment. They may have a map that is accurate down to the parcel level. By cross-referencing the local resource with the satellite view in ward map, you have a good chance of positively identifying what building is associated with a member's address.

GIS is a map-based database/application that many governments use to manage the things they are responsible for.

What is this?
For our purposes in discussing verification of household locations GIS (geographic information system) is used by local government agencies to show geographic, building, and other related data on one map. In some areas, local municipalities, counties, and other agencies use this computer system to map streets, buildings, houses, and other man made structures overlaid on natural features. Some of those agencies make these GIS maps available to the public through their web sites free to the public. These GIS maps are quite accurate and are a good source to precisely locate an address without having to physically visit the address.

Some governmental GIS maps are easy to use while others seem to require a degree in GIS programming to understand or use. In more dense population areas where the local government agencies have financial resources to invest in GIS technology the resources they provide online are quite useful. In the more rural or economically limited areas the availability of government GIS online resources may be totally absent. My experience has been good in many of the areas I have lived.

Whether or not you want to pursue using governmental GIS maps to help verify household locations is dependent on the availability, the ease of use of those local GIS map resources, or even your own technology savvy .

You can use an IP geolocation service to obtain an approximate location from where the user is connecting. Compare this with the GPS data received and you can weed out some extreme cases (players connecting though proxy, etc). You can even calculate distances between user logins and if they are too high (say, the location moved 1000 kms between two login attemps in 5 or 10 minutes) notify the user.

However this isn't foolproof and you will cause more than one inconvenience to legitimate players.

One thing I dislike with the new ward map is that all of our verified locations from the previous ward map tool didn't carry over. We get to start all over again :(

For our ward, as near as I can tell, all the verified locations came across just fine.
