From Bob White, E911 GIS Manager:

The layer e911rds is updated on a daily basis as towns report changes to their addressing data. Commercial data providers are often many months behind as they are updateing the entire country.

As for differences between e911rds and the MeDot roads these are usually minor and are often resolved through the maintenance process as it pertains to spatial issues.

When it comes to attribute issues the two data layers are for different bussiness needs and therefore maintained differently.

For the past 10 plus years we have periodocally met and discussed how these two data layers could be merged into a single layer. This week I have been attending a workshop at the national level where that very topic had an entire day dedicated to it.

As far as which data layer is better as a general rule the two data sets that Maine maintains are updated frequently. Which one is better between those two really depends on your needs.

I will be traveling back home tomorrow and am willing to discuss this next week in detail.

Re: Planning Project Update





Good List, however I would like to mention that from my preliminary review of the E911 centerlines and MEDOT centerlines in comparison to centerline of 2 most widely used sources (NAVTEQ and TELEATLAS) for street data in comparison or overlaid to Google Earth.  I have found that there is a lot of mismatch between Google and our local (E911 & MEDOT) sources.

 

Has anyone else seen this?  What source is considered to be correct or mostly correct?

 

All your input would be appreciated as I’m under a task of developing a new state landbase and then there is addressing, not address ranges.  That is another question that can wait, but address ranges without knowing what that towns standard (50, 100’, or 200’) becomes very difficult to determine.  Then you have towns that have their parcel data with addressing posted to their websites, but we don’t have access to that data from the state website.

 

All input and suggests are welcome.

 

Thanks,

 

Greg Davis

In a continuing effort to keep the Maine GeoSpatial community aware of the actions taking place on the GeoLibrary Board's strategic planning efforts, the Sewall Team has summarized input received from the Maine Geospatial community, the 2002 Strategic Plan and the GeoLibrary Board and provided the following chart entitled, "Overall Maine GeoSpatial Listing of Issues and Action Items."  The chart attempts to summarize the action items and issues needing resolution.  Each issue or action item has a "potential solution" indicated for it, a time frame for implementation and a priority.
 
We would appreciate it if you could take a look at this summary and provide us with input on them by sending an e-mail to: [log in to unmask] with the subject heading noted as "Maine Stakeholder Input."
 
Once again, we thank you for your time and effort.

 

On behalf of Bill Hanson, GeoLibrary board chair…
