Navigation SDK

deCarta's Navigation SDK is a software developer's environment that enables easier and efficient development of a customized navigation system for portable navigation devices (PNDs).

The NavSDK provides an Application Programming Interface (API) for accessing all of the required basic functions needed for the creation of a navigation application, thereby reducing development time, which results in overall reduced time to market.

The use of the NavSDK also ensures the compatibility of the navigation application with new releases of the underlying route engine. In addition, the NavSDK provides developers with a uniform data model that enables the use of map data from multiple and different vendors with minimal or no impact to the application. The NavSDK includes the deCarta Rich Map Engine (RME), which is the underlying technology deployed by many of today's leading Internet and navigation solution providers.

Ease of Integration

deCarta's Navigation SDK is a comprehensive development suite with software libraries, sample code, sample data and complete documentation. The SDK provides an Application Programming Interface (API) for accessing all of the functions required to create customized navigation applications, allowing customers to bypass "trial and error" phases and reduce development time to bring products to market faster. To help accelerate development, sample applications in source code are included to illustrate to developers the use of all the navigation functionality supported. In addition, the Navigation SDK provides developers with a uniform data model which acts as an abstraction layer that enables the use of map data from different vendors with different geographic coverage with minimal or no impact to the application.
