Near-Infrared Imagery (NIR)
Near-infrared imagery (NIR) captures wavelengths emanating from vegetation to produce a more detailed orthoimage for monitoring and analysis of vegetation, soil, and wetlands. In a NIR image, the internal cell structure of vegetation strongly reflects the NIR wavelength, providing a more robust indicator of plant health than the visible green wavelength reflection of chlorophyll in the leaves.
Common Applications for Color-Infrared Imagery
Utility Engineers and network stakeholders use CIR imagery to monitor and manage vegetation encroachment along utility infrastructure and pipelines. Early detection of unhealthy vegetation can prevent damage to vital infrastructure.
Planimetric mapping is the representation of natural or man-made features layered on a map. Features are extracted from orthoimagery data in the form of lines and polygons. There is a vast amount of information that can be derived from base map data which supports a multitude disciplines. ASI provides innovative solutions for extracting valuable information from base maps.
Anything visible in the orthoimagery can be digitized but common items found in planimetric maps include:
- Building footprints
- Street and curbs
- Impervious surfaces
- Utility lines

Imagery has an amazing amount of information, but raw aerial imagery cannot be used in for GIS until it has been processed such that all pixels are in an accurate (x,y) position on the ground. Orthorectification is the process of converting images into a form suitable for mapping by removing sensor and aircraft motion and terrain-related geometric distortions from raw imagery. The orthorectification process requires an accurate description of the sensor, detailed information about the sensor location and orientation for every image, and an accurate digital elevation model (DEM). After imagery has been orthorectified, it can be used within a GIS and accurately overlaid with other data layers
Layer-up Your Basemap
Your basemap imagery deserves layers. Our photogrammetry & GIS specialists can add above ground planimetric features, topographic contours, vector detail, and more. These additional layers add value to your data and help capitalize on your existing or future imagery.
