Remote data acquisation and QC tools for vehicle navigation mapping solution

Auto navigation assistance equipment (NAVI) have become common accessories for many vehicle these days in Malaysia. Regardless OEM or portable, NAVI has created an epidemic until drivers gave 110% confidence for every turning direction provided. Many did not realize that number of accident cases that involving NAVI units has been piles up in these 5 years either globally or Malaysia itself. Productions of NAVI start from data capturing till data conversion to compact disc navigable format. Remote sensing data with high resolution satellite imagery (HRSI) can provide extensive information on road, building, and landform. Attribute data that can be derive from images are merged with spatial data to built a database. Data feature are road mark, road regulation and road restriction. On site visit by GPS is to collect information that invisible in remote sensing image. These feature known as standing feature and only appear as dot or did not appear at all in the image. Roadsign, signboard and Point of Interest (POI) are amongst feature that best capture by on site visit. Quality check (QC Tools) on data were separate into spatial and logic script. Spatial QC Tools tackle error on shape of the feature and logic QC Tools will detect existence of violation in attribute rules for each feature. Manual guideline on remote data acquisition and development of QC Tools that been design to cater Malaysian road and POI perspective should be able to complement ISO GDF : 14825 that globally adopted as reference by map provider. To move forward, Ministry of Transportation or other authorities body that involved in safety issue for auto industries are propose to set up a clear rules depicting “how and what” must be comply by map provider when producing a map for auto navigation to ensure NAVI will not contribute to higher number of accident in the country.
