Land surveys are an essential part of any land development or property ownership process. They provide accurate measurements and information about the land, which can be used for various purposes such as construction, property boundaries, or legal disputes. There are various types of land surveys available, but three of the most common types requested are boundary surveys, topographic surveys, and ALTA/NSPS surveys.

  • Boundary Surveys:  Boundary surveys are the most common type of land survey requested by property owners. These surveys establish the exact boundaries of a property, determining where one property ends and another begins. They are crucial for resolving property line disputes, ensuring that property owners are aware of their rights and responsibilities regarding their land. Boundary surveys involve a thorough examination of the property's legal description, existing land records, and physical markers on the ground. Surveyors use specialized equipment like total stations and GPS devices to accurately measure and map the boundaries.
  • Topographic Surveys: Topographic surveys provide a detailed representation of the physical features and characteristics of a piece of land. These surveys are essential for various purposes, including land development, engineering projects, and environmental assessments. Topographic surveys measure and map the elevation, contours, vegetation, water bodies, structures, and other natural or man-made features on the land. This information helps architects, engineers, and developers understand the terrain and make informed decisions about design, construction, and land use. Topographic surveys are typically conducted using advanced surveying techniques and equipment to ensure precise measurements.

  • ALTA/NSPS Surveys:  ALTA/NSPS surveys, also known as American Land Title Association/National Society of Professional Surveyors surveys, are often requested during real estate transactions, especially for commercial properties. These surveys provide a comprehensive assessment of a property's boundaries, improvements, easements, encroachments, and other relevant details. ALTA/NSPS surveys follow specific standards set by the American Land Title Association and the National Society of Professional Surveyors. They are more detailed and comprehensive than traditional boundary surveys, as they involve extensive research, fieldwork, and documentation. ALTA/NSPS surveys provide a high level of accuracy and reliability, ensuring that all parties involved in a real estate transaction have a clear understanding of the property's characteristics and potential issues.

In conclusion, land surveying including boundary surveys, topographic surveys, and ALTA/NSPS surveys are three of the most common types of surveys requested. Each survey serves a specific purpose and provides valuable information for property owners, developers, and real estate professionals. Whether you need to establish property boundaries, assess the terrain, or ensure a smooth real estate transaction, consulting a professional land surveyor and obtaining the appropriate survey is crucial for accurate and reliable results.

Gonzalez Strength Associates is excited to offer our clients state of the art technology with Interior Lidar Scanning (laser measuring) for your architectural needs. The time-honored methods of manual data gathering using tape measures, distometers, drawings and photographs are fast being superseded with this innovative technology.

Our Lidar scans can provide clients a 3-D view/model of building interiors with astonishing detail and accuracy.

This specialized surveying tool uses an advanced high definition laser scanner to collect millions of data points. GSA’s skilled technicians then use the data points to develop a 3D computer model which can be exported to traditional CAD software for analysis and rendering providing you with precise calculations and measurements. Lidar scanning is optimal for a variety of projects by assisting in spatial planning, scale, and aesthetic development such as a furniture lay-out template and lighting designs with a relative accuracy to within ⅛ - 1/16 of an inch. Lidar scans are a great asset for client presentations as a spatial model for visualization of room size and shape for interior decoration and building renovations.
