Prof. Michael Peterson

University of Nebraska at Omaha

Title: Evaluating Feature Density on Large Scale Online Maps

Access Zoom Recording


Comparing large scale maps from services like Google, Microsoft Bing, and Mapbox serves to evaluate both the rendering of the maps and the quality and completeness of the underlying vector data. A method is introduced to evaluate feature density for online mapping services. The comparison procedure generates map pairs at random locations using the Application Programmer Interface (API) for the different mapping services. The quality of each representation is then evaluated for feature and label density. The comparison is done for three different continents. For North America, it was found that maps from Google had consistently higher feature and label densities than those from Microsoft Bing and Mapbox. Google’s advantage in Europe was slightly less pronounced. Maps from Microsoft Bing were more detailed in Sub-Saharan Africa in comparison to both Google Maps and Mapbox. Maps from Mapbox, that relies exclusively on OpenStreetMap data, had the lowest feature and label density for all three areas compared to the other two services.

Access Zoom Recording

About the talk:

David will give a fast-paced overview of modern survey data collection and data processing techniques. As well as touching on developments in GNSS receivers, total stations, laser scanning systems and photogrammetry he will look at the integration of these technologies at the equipment level and at the data processing level. 

About the Speaker:

David Cameron-Mackintosh is a Sales Director at Survey Solutions Group, one of the largest survey equipment suppliers in Scotland, who provide surveying equipment to many of the large infrastructure projects in Scotland such as the recent M8 upgrades, the new Queensferry Crossing and the Edinburgh Trams project as well as supplying many of the Scottish land survey companies. Their main focus is to allow their users to use the latest surveying technologies successfully.

As a graduate of Glasgow University he has been a guest lecturer for their Civil Engineering Surveying course in recent years. After several years as a land surveyor and a land survey manager he has been working with Survey Solutions Group for the last 17 years.
