Improving Data
Eliminate data that does not measure up to standards
Verify and/or correct the available data
How to recognize erroneous data?How to avoid false positives or negatives?How to minimize data waste?
![Page 5: Precision Geocoding through Quality Addresses Address Quality for Location Intelligence](https://reader031.vdocuments.us/reader031/viewer/2022032311/56649dac5503460f94a9ad43/html5/thumbnails/5.jpg)
Data Verification & Correction
Recognizing erroneous data starts with:
Validating every recordAn extensive reference database
Fixing erroneous dataAgain, work entry by entryRequires knowledge of the correct format and value of the data
This can be done by hand, or automated
How critical is it to correct the data?

LI doesn’t make small mistakes
Location data and analysis improve business functions in multiple ways
![Page 7: Precision Geocoding through Quality Addresses Address Quality for Location Intelligence](https://reader031.vdocuments.us/reader031/viewer/2022032311/56649dac5503460f94a9ad43/html5/thumbnails/7.jpg)
LI and Retail
Shopping centers rely on analytics to:
Reach the target audience
Optimize distribution and supply logistics
Analyze local trends and customize marketing campaigns
Create localized merchandizing for customers
Example

LI and Real Estate
Real estate benefits from:
Accurate zoning
Integration between multiple data sources
Accounting for external features such as roads, adjacent
neighborhoods, and shops
Avoiding potential disaster areas
(floods, tornado lanes)
Example

GIS and Insurance
Insurance companies use analytics to:
Determine property values
Assess risk based on topographical factors
Identify affected zones for health insurance
Determine hazardous zones globally
Plan and implement disaster recovery efforts
Example
