Celebrating over 100 years! 

Our History

National Survey Service, Inc. is a successor to A. Malkin, Inc., which commenced its land survey services in 1917. National Survey Service, Inc. was formally organized in 1926 and has been in continuous service since that date. The firm is a member of the Illinois Society of Professional Land Surveyors.

We are land surveyors and specialize in the establishment and determination of legal property lines and boundaries in connection with the purchase and/or development of land tracts for purpose of present or future construction.


This type of work is usually required by attorneys representing sellers and purchasers, title companies and frequently architectural or engineering firms who would need the survey in connection with the design and construction of improvements on said tract of land. We also prepare Plats of Accident. A principal of our firm is available for court appearances should it be necessary.

Featured Service:

3D Laser Scanning

Click HERE for further information 


3D scanning is a process of shining laser lines in order to collect three dimensional data. The surface data is captured by a camera sensor mounted in the scanner which records 3D points in space. The survey points collected combine, resulting in a point cloud that represents the surface surveyed.

*Point clouds can be viewed in multi-color thermal hues or true color from digital camera images as seen below. 

Laser Scanning equipment we utilize:

- Trimble TX5

- Trimble TX8*

- Trimble GeoSLAM 

  • 3D mobile mapping technology

  • SLAM (Simultaneous Localization and Mapping)

  • Rapid scans for difficult-to-reach places 

  • Exponentially quicker scan times than traditional techniques

  • Great for occupied space

    • Live construction sites

    • In-use buildings surveyed for renovation or redevelopment

- Leica RTC360*

- Leica BLK
