Partners Engineering, LLC, on behalf of the City of Georgetown, chose Sanborn to plan, implement, and collect Light Detection and Ranging (Lidar) data to acquire detailed surface elevation data for use in conservation planning, design, research, floodplain mapping, and to update their previous Lidar surface for 224 square miles of Georgetown Texas.
This data is for planning purposes only and should not be used for legal or cadastral purposes. Any conclusions drawn from analysis of this information are not the responsibility of Sanborn Map Company. Users should be aware that temporal changes may have occurred since this dataset was collected and some parts of this dataset may no longer represent actual surface conditions. Users should not use these data for critical applications without a full awareness of its limitations.
Lidar data for Texas is made available online through the use of data compression using LASTools. LASTools is an open-source collection of tools for lidar data viewing and manipulation. TNRIS uses the LASzip portion of LASTools for compression\decompression. LASTools provides a lossless compression of the data from las to laz formats.
