Preserve and Protect Oversized Documents
Blueprints, engineering drawings, maps, and other oversized records are essential for projects—but paper fades, tears, and takes up valuable space. Our large format scanning service converts your physical documents into high-quality digital files that are easier to store, share, and protect.
Why Scan Large Format Documents?
AEC (Engineering, Architectural, and Construction) firms must keep final building plans for compliance and emergency use. Storing them in racks, flat files, or piles makes searching difficult, costly, and time-consuming—often exceeding $5,000 a year. Scanning eliminates the hassle of flat files and storage rooms, giving you instant access to your documents in digital form. Electronic files are simple to search, easy to share with teams and clients, and protected from the risks of damage, loss, or fading. You’ll also streamline compliance by keeping organized, auditable records.
Our Process
We handle fragile and oversized originals with care, scanning them in sharp detail using advanced large-format equipment. Files can be delivered in PDF, TIFF, or JPEG formats, and we can organize and index them for quick retrieval. Whether it’s a single set of drawings or an entire archive, your documents are captured with precision and returned securely via download, USB, or external media.
Digitizing with GISI
GISI has over 28 years of large format scanning experience, including scanning for the Hoover Dam, Reno-Tahoe Airport, and PG&E (Pacific Gas & Electric Company). We can scan and index your drawings, creating a searchable database customized to your needs. Using our OASIS Document Management Software, we can organize by project number, permit, revision, date, or any fields you choose. As large-format scanning experts, we secure your records and make them easy for your team to access when needed.
What We Scan
From architectural blueprints and construction drawings to electrical schematics, survey maps, EKGs, lengthy medical printouts, well logs, and posters, we specialize in scanning documents of any size or format—even oversized or aging originals.
Large Format OCR Available
Did you know that we have the technology to OCR your large format drawings? For maps with a good scan we should be able to get the majority of the text utilizing the latest technology.

Customer Success Stories
The Graphic Imaging Services, Inc. team was very professional and displayed true teamwork in working with our in house employees and our additional contracting staff. Our project goals became their business goals. They were continually looking for methods and work practices that would help us improve our map product, reduce our budget and maintain our project schedule.
We recently worked with GISI to purchase a Contex Quattro X Scanner to digitize our large collection of engineering drawings, some dating back decades and in fragile condition. The process could have easily been overwhelming, especially since I had no technical background in scanners. But from the moment I reached out through their website, Lisa and her team made everything simple and stress-free.
Within hours of my inquiry through their website, someone from GISI gave me a call to go over what we needed. Over the following days, I reached out many times with questions – everything from scanner types to how the equipment handles delicate paper – and every time, they responded patiently and thoroughly. Lisa even scheduled a meeting with their technical team to present different technologies and walk me through the best options for our situation.
Once we placed the order, the scanner arrived right on schedule. Their team supported us through the installation, and when I noticed the calibration sheet was missing, Lisa immediately arranged to have it shipped out. That kind of prompt response really stood out. It’s been a true pleasure working with Lisa and GISI. Their professionalism, responsiveness, and genuine care for their customers made the entire experience easy and enjoyable. I wouldn’t hesitate to recommend GISI to anyone looking for excellent service and high-quality scanning solutions.
I am the Director of Cartography and Geospatial Technologies for Statistical Research, Inc. (SRI), one of the nation’s largest dedicated cultural resource management consultants with offices in Arizona, California, Colorado, New Mexico and Washington. Since 2022, I have had the pleasure to work closely with Graphic Imaging Services, Inc. (GISI) on two large, complex scanning, digitization and data-quality projects focused on archival cultural resource management documents maintained by the Arizona and Nevada offices of the Bureau of Land Management (BLM). Our work entails scanning documents from these archives, then ensuring that the spatial data (archaeological site and project boundaries) and attribute data they contain is fully captured within a geographic information systems (GIS) database. In the case of the Arizona BLM project, the larger of the two, this work entails scanning all primary cultural resource management documents within the archives held by the BLM’s Lake Havasu and Safford Field Offices, which together manage BLM lands across nearly a quarter of Arizona. The thousands of individual documents held in these archives date back more than 50 years and include a wide range of media, from bound reports to large-format maps and transparencies to field notebooks and hand-drawn sketch maps written in pen or pencil. Scanning these archives required a GISI team to be onsite at each field office for months at a time. From the onset of of the work, GISI collaborated closely with both SRI and the BLM to ensure they had a complete understanding of which documents fell within the project scope and what equipment and methodology would be required to ensure each document was properly scanned and cataloged. This close coordination continued for the duration of the scanning process, whenever situations arose that required input from SRI or the client. As a result of their technical expertise, attention to detail, and general excellence, GISI finished work at both field offices ahead of schedule and under budget. My crews of geospatial analysts have now worked closely with the documents scanned by GISI for many months and have found them to be a high-quality, high-resolution archive that has completely met our needs. I am therefore happy to wholeheartedly recommend GISI’s services and look forward to working with them again in the future.
