Historical and Environmental Data For All Your Needs

We want you to get the right information for your project at the highest level of quality. For the past two decades we’ve been honing our skills and our tools.

For environmental consultants, engineers and land use planners:
Our staff includes former environmental professionals and we are very knowledgeable about the ASTM environmental due diligence standards. One of our principals is an ASTM International E50.02 Subcommittee officer and regularly participates on the task groups that work to create and revise the environmental assessment standards. This means we know how to deliver data that meets the current requirements and beyond. We can help you select the best products and services based on your site location and the goals of your project.

For libraries, government entities and researchers:
Digital documents and images are easy to use and share so HIG has designed and built specialized scanning and camera equipment to capture the best possible images of historical documents of all types and sizes. We specialize in digitization of historical aerial photographs and maps using high resolution techniques. The resulting digital collection can be customized to make it easy to search and use, making it more valuable and more available to the people who need to use it.
