Quality Assessment

Data Integration

Produce BB Map

National broadband map overview

• The National Broadband Map is a program of the National Telecommunications Information Administration

• Authority comes from ARRA and BDIA

NTIA “shall create and maintain a National Broadband Map”

Map “shall be on-line and searchable and interactive”

• Grants to each state and territory for assembling and collecting the data

NTIA and FCC entered into a partnership to help produce the map


National Broadband Map - Overview

National broadband map

NTIA awarded grants to each state; state mapping broadband availability;

Technology and speed available, by provider at the US Census Block level

Community Anchor Institution Data

• Collect data twice a year (April and October)

Map to be published on 2/17/2011

Data integration review data
Data Integration – Review Data

  • Each submission contains; a Geodatabase, some summary information, metadata, and a process paper

  • Standard process for reviewing the data

  • Issues we have seen

    • No documentation, record count differences, no metadata, valid values in data

Data integration completeness analysis
Data Integration – Completeness Analysis

  • How much availability is there (e.g. by population and housing units)?

  • How much speed is there (e.g. by population and housing units)?

  • Did we get all the right providers?

  • Did we get all the right community Anchor Institutions?

Mobile app
Mobile App

  • We have a contest planned for a mobile app

  • To be released by April 2010

Your help needed

• What would a mobile app do?

• How do we truly define something ‘unique’ that significantly adds value to community?

Your Help Needed

Data integration review data1
Data Integration – Review Data

  • Layers include – (1) Block level, (2) address level, (3) road segment level, (4) wireless, (5) CAI, (6) middle mile and an (7) overview

  • (8) Last mile and (9) subscriber weighted nominal speed

  • Check each field for valid values, accepted ranges, and combination of values

  • Check geospatial data for vertex limits, geometry errors, projection and topology rules

  • ETL data into a staging database

Fcc gov developer

• Most major federal datasets built on Census geography

• First dot gov API to unlock data at Census block level

• Wide-reaching benefit across government agencies

Announcing – FCC Census Block Search API
