增强现实结合地理学展示你看不到的一面世界

使用地理信息系统(GIS)创建地图始于20世纪60年代。2017年，一家成立于1969年的地理空间数据公司Esri，发布了一款名为AuGeo的AR应用。同年，美国警方使用AuGeo应用程序，通过3D模型对视线进行分析，从而创建一个标准的安全程序，以防范狙击手的袭击。2019年1月，以色列特种部队在巴西大坝决堤前使用AuGeo创建了一个覆盖的地形，让第一时间做出反应的人能够快速确定方向，并开始寻找幸存者。
Augmented Reality And Geographic Information Show You What You Can't See In The World

Creating maps using geographic information systems (GIS) began in the 1960s. It formed the backbone of geographic science including spatial analysis and visualization.
In July 2017, geospatial data helped the Thai cave rescue team save the lives of 12 people. That technology, mapping and analytics software came from Esri, a geospatial data company founded in 1969.
That same year, Esri took a step into augmented reality (AR) through their internal research and development group, Esri Labs, and released an AR app called AuGeo. Available in both Android and IoS, the AuGeo app has been used by the Illinois State Police to enable a line of sight analysis with a 3D model to create a standard security procedure to protect against snipers, showing areas where views are unobstructed from the tallest point.
The Israeli Special Forces also used the AuGeo app to create an overlay of the terrain before the flood in the January 2019 dam break in Brazil to allow first responders quickly orient themselves and begin to search for survivors.
"In scenarios where streets and prior structures are covered (flooding), the augmented view allows you to reconstruct what is where in the context of where the searcher is standing. With the augmented view, searchers can go directly to where buildings once stood to prioritize where to search for survivors," said Ryan Lanclos, Director, public safety industry solutions, Esri.
Lanclos says the user only needs some data point of features (points of interest, the location of assets, etc.) and a mobile device to use the AuGeo app.
"There is some simple data preparation needed to 'create a view' and tag it in the AuGeo app, but after tagging, the data can then be downloaded to the device," said Lanclos. "The AuGeo application exposes settings that allow the user to tune to the best settings between the augmented view and the sensor parameters."
