Height data, also known as elevation data, is used by mapping companies to offer accurate mapping models of today’s world. Gathering Height DataMapping companies are constantly finding new ways of gathering height data in order to remain on the forefront of mapping technologies. Some ways mapping companies have captured height data are by land-form panorama, land-form profile, high resolution satellite imagery, linda data, synthetic aperture radar (SAR), and digital photogrammetry. Uses of Height Data TodayThere are many ways mapping companies have used height data in order to make valuable resources. Here are just a few examples of the way we use height data in mapping today. 1. Consumer-Based Products and ServicesWith products and resources, GPS systems and GoogleMaps, mapping has become commonplace in our lives. The height data mapping companies use to make these products provide the most up-to-date and valuable information for consumers. Even most phones these days are equipped with mapping software, and with phone such as the iPhone, it is simple to find mapping applications that use height data, such as hiking and traveling applications. Virtual travel is also another way general consumers use height data. Our world’s landmarks can now be seen in 3D with just a quick click of a mouse. 2. Land AnalysisThe most up-to-date and accurate height data is very vital in the field of land surveying and analysis in order to help with such projects as land plotting, environmental services, flood modeling, disaster preparedness, and city development. Telecommunications has also relied on the analysis of height data in order to evaluate the terrain for the improvement of mobile communication networks. 3. AviationSafety and accuracy in aviation has relied heavily on height data in mapping with such flight programs as collision avoidance systems, moving map displays, Intermap’s topographic mapping programs, synthetic vision, and flight simulators. Accurate height data has allowed mapping companies to offer the most valuable resources, and mapping companies are constantly finding new ways to gather and integrate height data into new software in order to develop even more interactive mapping.
