If you want to make visual representation of data for users of your programs, APMap is exactly what you need.APMap is not just a simple GIS, but a component library for reflecting data on geographical maps and schemes in your programs.They are typically equipped in a van with an extremely sensitive GPS receiver and sometimes a few video cameras.These mappers go out to map roads that have changed positions, new roads, and new residential areas.Unfortunately until that happens you can expect even brand new GPS systems to contain data that is sometimes several years old.This tutorial shows you how to display the geographic location of a user or device on a Google map, using your browser's HTML5 Geolocation feature along with the Maps Java Script API.However it appears this scenario will continue for the near future.Perhaps down the road manufacturers and mapping companies can work out an automated system whereby the the manufacturer will receive updates, the updates get converted into the manufacturer’s proprietary format, and finally changed data offered for download into the GPS receiver.

They need to convert the data into their own internal formats.

APMap contains native Delphi component, that may be compiled into your programs and don't need external files (dll, ocx etc.).

There are two major companies who provide the data for most GPS maps, Tele Atlas and NAVTEQ.

The GPS companies also write the programming for calculating routes which is why different GPS systems often calculate different routes even though they have the same underlying map data.

Once the new data is converted into the proprietary format of the manufacturer it needs to be produced in a format suitable for distribution. Some companies offer this updated data on a yearly basis, some less often, and there are a few GPS manufacturers who I’ve never seen offering map updates.Therefore it might take them a little while to gather those corrections.
