Advances in Mapping Make Work Easier

GPS data collection systems use a tiny receiver inside your dashboard unit. This small receiver picks up calls from a minimum of three satellites circling the earth; the triangulation method. Much like mariners used in the days before technology, your approach “triangulates” your assignment based on the intersecting point of circles that means the distance from each satellite about where your division is. Then normally, a fourth satellite is used to define movement and speed.

GPS data collection technology uses signals from military satellites to identify a user’s exact geographic location. But most of the time, knowing your precise latitude and longitude–in and of itself–is not particularly useful. Instead, the real significance of GPS lies in the interface between the positional signal from space and the mapping data stored inside each receiver.

Drivers subsidizing inexpensive GPS data collection services are now requesting better and more up-to-date maps and details, and manufacturers are trying to respond. Unfortunately, new GPS updates for specific brands and standards are occasionally erratic. As a result, you may buy a new unit with pre-installed mapping software, only to see new software released soon after. This, together with the cost of the mapping updates, is a common source of irritation for GPS users.

To comprehend why this happens, it’s helpful to know something about the process of GPS data collection. First, GPS data collection companies provide their geographic information. Then, the mapping companies continually survey and re-survey different areas and update their databases accordingly.

Data gathering for new maps is a time-consuming and expensive process. And once the information is collected, it can take a while for GPS manufacturers to convert it into their specific software formats and produce GPS updates (in the form of a download or DVD) for distribution.

Land surveying is a technique used to precisely determine the 3D (three-dimensional) or terrestrial position of points, angles, and distances between them. These points detect boundaries and land maps for governmental purposes or ownership. Surveyors typically utilize engineering, mathematics, law, physics, and geometry to map and survey lands.

Mapping and aerial surveying are indispensable in land surveying. While the majority of the earth’s surface is photographed at a specific altitude to create maps, many methods require a more reasonable view of the land at a larger scale, together with more accurate data points. These are made from satellite imagery, and helicopters or airplanes are used in taking land photos.

Aerial mapping started in the middle of the 19th century when hot air balloons were used to take photographs from the air. Since then, the growth of this technology became even more popular, especially after the launch of Sputnik, which marked the start of the satellite imaging period.

Photogrammetry is one of the earliest remote sensing methods utilized for creating maps and is still used. It determines measurement through photography, where data is captured every second of the plane’s flight.

On the other hand, using 3D laser technology is unnoticeable, and setting foot on land is not required. This is beneficial for surveyors tasked to survey steep slopes and dangerous terrains. Mapping land with limited access is made easy with aerial mapping. It includes 3D map creation through accurate measurements of location and elevation, as opposed to aerial photography, which fails to produce accurate data or detail.

LIDAR (Laser Imaging Detection and Ranging) technology uses laser beams to make a 3D land image or model. When used together with GPS (Global Positioning System) equipment, LIDAR gathers data of location and elevation, which are then turned into a geographic map. Collected data are utilized in applications like topographical maps.

These systems are used by engineers, technicians, planners, GIS (Geographic Information System) experts, and surveyors. It is a more accurate information gathering technique compared to traditional methods.

They are familiar with every aspect involved in data gathering. They employ subcontractors who have mapping capabilities and maintain professional relationships as they work with them in their following projects—backed by experts in the field, the best handle these projects. They are associated with the best contractors in the industry to ensure accurate results using LIDAR and high-precision digital land parcel modeling.

Experts choose aerial mapping because they allow faster data collection. The digital data collected are utilized by engineers, surveyors, city planners, geologists, and experts to produce accurate maps.

It also proves helpful inaccurate data gathering for every land mapping and surveying purpose. Experts use these to produce topographical maps equipped with the latest data-gathering technology. Supported by  and other indispensable technology tools, the task is easier and faster, with more accurate results than traditional methods. ViaVista Mapping helps create searchable burial plot maps.
