GIS & Mapping

Through our GIS and mapping services we gather, organize, and analyze spatial and non-spatial data. We provide the most beneficial formats for client specific data including highly detailed planimetric, topographic, orthomosaic, and thematic mapping.  Our utilization of GIS as a tool enables our clients to modernize their processes by creating, maintaining, and manipulating data utilizing geodatabases, and provides a powerful platform for data exchange and collaboration. Below are examples of deliverables our clients have come to depend on. 

Orthomosaic

Orthomosaic maps are created using photogrammetry, which involves taking aerial photographs, called orthophotos, and then analyzing them to determine the location of each pixel.  Drone images undergo correction for image distortion and are seamlessly merged during post-processing to generate remarkably high detail and resolution.  Orthomosaic maps are increasingly being for conservation, for mapping after disasters, for tax valuation purposes, and as shown here for real estate to provide interactive maps of properties and site development progress.       

Topographic

Topographic maps use elevation contour lines to show the shape of the Earth’s surface and landforms.  They have many uses including geographic planning, large scale architecture, mining, civil engineering, etc. Topographic maps are also called contour maps and are commonly requested by clients as shown here for commercial planning.   

Digital Elevation Models

Digital Elevation Models (DEMs) are elevation models that capture both the environment's natural and artificial features and can be generated from various methods.  These models include bare-earth elevation as well as the tops of buildings, trees, powerlines, and any other objects.  The basics of DEM analytics include data acquisition, data modeling, data management, and application development.  DEMs can be used for modeling water flow or mass movements such as landslides, creating physical models such as raised relief maps, rendering 3D visualizations, and analyzing terrain such as show here for a transportation client of ours.              

Planimetric

Planimetric maps consist of lines drawn around both man-made and natural features. These features are extracted from aerial photography—anything visible in the imagery can be digitized. As shown here in the city park map our team created, typical items found in planimetric maps include building footprints, trails, sidewalks, etc.
