Curious about the historical marker you just whizzed past on your drive? If you reside in Texas, there’s an app to satisfy your curiosity. Texas Roadside History provides information on historical markers in the state through a user-friendly mobile application.

Texas Roadside History Development

The initial idea for Texas Roadside History came from a Windows Phone 7 “lock-in” event organized by the Slalom Consulting Dallas office. The team wanted to learn how to utilize Microsoft’s SQL Azure and Azure Web roles effectively.

Harnessing SQL Azure

During the app’s development, SQL Azure was employed to take advantage of the Geography data type and the STDistance function. These key features enabled the team to query historical markers based on proximity.

Exposing Data via WCF Web Services

A WCF Web service was created to perform proximity queries and generate an OData endpoint using WCF Data Services for basic data access needs.

Approval Process and Impressions

After multiple submissions and rejections, Texas Roadside History was finally approved in the WP7 Marketplace. Microsoft’s thorough and detailed rejection reports allowed the team to focus on improving the app’s quality.

Expanding to iOS

Following the app’s initial development, the team decided to explore the world of iOS. With the help of MonoTouch, it was easier to get started, and the focus shifted to learning iOS APIs.

App Store Submission Experience

The Apple App Store submission process via iTunes Connect was quite different from the WP7 Marketplace experience. Although it was faster, taking only four days from submission to approval, the iTunes Connect site was more challenging to navigate.
