What data do gis and light detection and ranging (lidar) technologies provide to portland city officials?

They provide images or 3D models of what is on the Earth's surface. LiDAR is used to create incredibly detailed maps in addition to assisting researchers in the fields of geography, archaeology, geology, seismology, atmospheric sciences, laser studies, etc. GIS integrates many types of data. It analyzes spatial location and organizes layers of information into visualizations using maps and 3D scenes.

LIDAR technology provides city officials with a three-dimensional view of the buildings and terrain of Portland. This LIDAR data in the GIS helps city officials analyze a precise representation of the city landscape when considering the consequences of proposed building projects, such as the shadow a building might cast or a scenic view it may obstruct.
