# Elevation Data Services ### Prius Intelli offers both [digital surface models (DSM)](https://priusintelli.com/solutions-and-services/digital-elevation-models/) and [digital elevation models (DEM)] (https://priusintelli.com/solutions-and-services/digital-elevation-models), as well as several other informative and specific elevation datasets that enable you to get a full picture on the terrain. With this data, you can support more informed: - Site selection efforts - Land development - Well site mapping - Environmental initiatives - Route planning PLEASE NOTE: *Imagery displayed on Trunkline is compressed and does not represent imagery's true resolution and quality.* ## Our high-resolution aerial imagery elevation capabilities include: [**Digital Surface Model (DSM):**](https://youtu.be/41M-0ucdJIg) - Captures both natural and artificial features, including the ground and everything above it such as buildings, trees, and objects. - It provides a comprehensive representation of elevations and features on and above the ground, facilitating a holistic understanding of the terrain. - DSM data helps in site selection for infrastructure development, such as power generation facilities and transmission lines, by assessing the te [**Digital Elevation Model (DEM):**](https://youtu.be/XkN_H7-4qsc) - Showcases only the ground surface within a given area. - All above-ground objects like trees and buildings are removed from the dataset, allowing for a clear representation of the bare Earth's terrain. - The DEM serves as a fundamental building block for other elevation datasets, providing crucial insights into the terrain without the clutter of trees and above-ground objects. - DEM data supports terrain analysis for the design and planning of power transmission routes, optimizing the alignment and minimizing the impact on the environment. [**Above-Ground Height Model (normalized DSM or nDSM):**](https://youtu.be/lqqlBjEWYeA) - An Above-Ground Height Model showcases only the above-ground objects such as trees and buildings, shaded by their height. - This model is particularly useful for understanding the density of building or tree cover in a given area. - Above-Ground Height Models aid in identifying potential obstructions, such as tree growth near power lines or buildings encroaching on uti [**Stream Networks:**](https://youtu.be/kBrhmBICjRc) - Illustrate how runoff behaves across an area. - It provides valuable information for understanding the flow paths and channels of runoff during rain events or in spill situations. - Stream Networks data assists in hydrological analysis for assessing potential flood risks and designing stormwater management systems near power infrastructure. [**Drainage Basins:**](https://youtu.be/3NSWy_W1aV4) - Delineates the natural divides or barriers within an area, outlining the entire catchments for the stream networks. - It provides a comprehensive view of the entire drainage basin for a given stream channel, pond, or lake. - Drainage Basins can be used alongside the Stream Networks dataset for hydrological planning, enabling a better understanding of water flow patterns and catchment areas. - Drainage Basins data aids in watershed management and water resource planning for power generation facilities that rely on water supply or cooling systems. [**Contour Lines:**](https://youtu.be/Uq1zIIn7u8E) - Showcases points of equal elevation across an area. - We can provide contour lines at the interval of your choosing, tailored to your specific requirements. - Contour lines are essential for understanding how elevation changes, where the terrain slopes, and the rate of elevation change. - They provide valuable information for various applications, including landform analysis, engineering design, and visualizing the shape and relief of the land surface. - Contour lines support the planning and design of power infrastructure by visualizing elevation changes and identifying potential slope stability issues. [**Slope Model:**](https://youtu.be/v4j1oAjij-0) - A shaded representation of the slope of the ground. - This model is useful for site suitability analysis, site selection, and construction planning. - The high contrast of a slope model helps identify problem areas that may not be easily recognizable in other maps or data layers. - Slope Models assist in assessing the topography for infrastructure development, transmission line routing, and identifying areas prone to erosion or landslides. With Prius Intelli's [elevation data solutions](https://priusintelli.com/solutions-and-services/gis-services/) and planimetric data services, you gain a comprehensive understanding of the terrain and infrastructure features in your area of interest. Our data offerings empower your geospatial analysis, enabling informed decision-making, efficient planning, and effective resource management across various industries and applications.
