Drone Mapping, Modeling, and Photography

SPC Engineering is equipped to perform high-resolution aerial mapping and photography using its state-of-the-art sUAS (small Unmanned Aircraft Systems, or drones) and photogrammetric software. Using drones in concert with GNSS receivers provides the ability to precisely map hundreds of acres or specific features (such as landslides, surface fault ruptures, and structural damage) within minutes, perform inspections in previously inaccessible locations, monitor progress of large construction projects, and create 3D models of buildings, lots, and slopes to as low as centimeter-level accuracy.

We fly our drones anywhere from ground-level to several hundred feet above ground to capture high-resolution images and video with our 20MP/4K camera. SPC Engineering personnel are licensed by the Federal Aviation Administration (FAA) and abide by the local regulations and FAA laws and guidelines.

GIS and Graphics


SPC provides capabilities of GIS and graphical services that aid our analysis and provide a visual representation of our opinions to clientele. The graphics are prepared either for design purposes or to convey our analyses in a clear manner  easily comprehensible to non-experts.

Our graphics production typically consists of

  • Digital maps
  • Aerial photography overlays
  • Topographic mapping, surface modeling and contouring
  • Geotechnical and geological cross-sections
  • Analysis of linear and volumetric objects

SPC’s graphics department is equipped with state-of-the-art equipment and software to produce graphical representations of spatial data such as:

Historical data:
 ●  Aerial photographs
 ●  Geologic maps
 ●  Grading & construction plans

Government GIS data sources:
 ●  Assessors and parcel data
 ●  Digital elevation models
 ●  Historic aerial photos
 ●  Digital elevation models
 ●  Seismic hazards
 ●  Alquist-Priolo fault zones
 ●  Hydrologic data

Survey data using the latest land-based, aerial and satellite technologies:
 ●  GPS
 ●  Total station

Our in-house library contains extensive amounts of technical journals, historical and recent aerial photos, geologic and topographic maps, satellite mapping information, and GIS data such as DRGs, DOQs, DEMs, and other reference material to support our analyses.

SPC utilizes the latest geospatial database technology for management of all aspects of our work including:

  • Project sites
  • Job files
  • Graphics
  • Laboratory testing
  • Subsurface exploration & testing data
  • Geotechnical resources
  • Geologic maps & data
