Why Should I Hire an ASPRS-Certified Mapping/GIS Expert?
This image from Tinley Park – part of Ayres Associates’ work for the suburban Chicago GIS Consortium – exemplifies a project where CP meets CMS-GIS/LIS. Much of the mapping Ayres does for local government is collected from aerial imagery and is delivered in GIS-ready format. In this example, paved surfaces and buildings are displayed on… Read More »

2D Modeling and Matrix Riprap Save Millions on Transportation Flood Recovery Projects
By Will DeRosset, PE, CFM, and Anthony Alvarado, PE, CFM The Colorado Department of Transportation recently published several case studies celebrating major progress in effective design in flood recovery projects. The projects all relate to designs implemented in the recovery from devastating 2013 flooding. The key takeaways are: 2D hydraulic modeling and spatially explicit analysis… Read More »
