HJW GeoSpatial is a privately-held California Corporation, with corporate headquarters in Oakland, California. HJW has been providing government and private-sector clients with professional geospatial services since 1949. As a leading full-service photogrammetric mapping firm, we provide a full, integrated suite of professional services including:
# Digital and film-based aerial photography, with flight services based in Oakland, CA, and a network of flying partners nationwide.
# Photogrammetric planimetric and topographic CAD-based mapping in support of conceptual planning and design engineering projects.
# LiDAR terrain modeling and photogrammetric integration.
HJW provides airborne LiDAR processing, terrain modeling,
photogrammetric integration and also coordinates new data acquisition.
HJW integrates orthoimagery and stereo photography into the LiDAR
processing workflow, allowing rigorous quality control of LiDAR point
geo-referencing, point filtering and match to control sources.
When many other photogrammetric mapping companies were just learning
about digital orthophotography, HJW was already developing our own
software and completing city-wide projects.
HJW stands ready to provide you with a full range of customized services
to accurately measure spatial features from aerial photography and
remotely sensed data. Our clients benefit from our expertise in all
aspects of photogrammetry; planimetric and topographic mapping,
analytical aerotriangulation, and Digital Terrain Modeling (DTM).
