The Different Types of GIS Data Capture Tools
Over the years, the types of GIS data capture tools used and how GIS (geographic information systems) data is gathered have changed dramatically. In the past, data was typically collected through labor-intensive field surveys and manual mapping techniques, which were time-consuming and prone to error. Today, however, there are numerous types of GIS data capture tools on the market that make it much easier to gather spatial data.
Types of GIS Data Capture Tools
One of the most significant advantages of the modern types of GIS data capture tools is their ability to gather data from multiple sources simultaneously. This allows users to create more accurate and comprehensive maps and spatial analyses, providing a wealth of information about the location and characteristics of various features on the Earth’s surface. Additionally, many of these tools can collect data in a variety of formats, making it easier to integrate information from different sources and use the data in a variety of applications.
Terrestrial Laser Scanning
Terrestrial laser scanning, also known as TLS or simply laser scanning, is a technology that uses lasers to collect high-resolution, three-dimensional data about the surface of the Earth. This data is typically collected using a laser scanner mounted on a tripod or other stationary platform, which is then used to scan a wide area of the surrounding environment. The scanner sends out a laser beam that reflects off of objects in the environment and back to the scanner, providing detailed information about the objects’ shape, position, and other characteristics.
Terrestrial laser scanning is commonly used in various applications, including engineering, architecture, and environmental management. In these industries, TLS is used to create detailed digital models of buildings, bridges, and other structures, as well as for mapping the topography of an area or monitoring changes in the landscape over time.
LiDAR, which stands for Light Detection and Ranging, is a remote sensing technology that uses lasers to measure the distance between the sensor and objects on the ground. In capturing GIS data, LiDAR is often used to create highly accurate 3D models of the Earth’s surface. This is done by mounting a LiDAR sensor on an aircraft or a drone and flying it over the area of interest. The LiDAR sensor sends out laser pulses and measures the time it takes for the pulses to bounce back from the ground. By combining these distance measurements with the precise location of the sensor, it is possible to create a 3D model of the terrain with high accuracy.
There are many benefits to using LiDAR to capture GIS data. One of the main advantages is its high level of accuracy. Because LiDAR uses lasers to measure distances, it is able to capture very fine details of the terrain, including slight variations in elevation. This makes it ideal for applications such as flood modeling, where even minor differences in elevation can significantly impact the flow of water. Additionally, because LiDAR data is collected from the air, it can cover large areas quickly and efficiently, making it a cost-effective way to gather GIS data.
Photogrammetry is a technique used to create maps and 3D models of the Earth’s surface by analyzing images taken from the air or space. Photogrammetry is often used to create highly detailed and accurate maps of the Earth’s surface. This is done using specialized software to analyze the images and extract information about the location, size, and shape of objects on the ground. The resulting data can be used to create 2D maps or 3D models of the terrain, which can be used for various applications such as flood modeling, urban planning, and land use analysis.
Remote sensing is a broader term that refers to the use of sensors to gather information about the Earth’s surface from a distance. Like photogrammetry, remote sensing is often used to capture GIS data. However, while photogrammetry is typically used to analyze images, remote sensing can use a variety of sensors, such as radar, thermal cameras, and spectrometers, to gather different types of data. This allows for a more comprehensive view of the Earth’s surface, which can be helpful for applications such as land use classification, crop monitoring, and environmental monitoring.
Mobile mapping allows users to collect geographic data using mobile devices like smartphones or tablets. This data is typically collected using a combination of GPS, sensors, and other onboard technologies, which are used to capture detailed information about the location and characteristics of various features on the Earth’s surface. Mobile mapping allows users to collect data in real-time, providing a wealth of information that can be used for many types of projects.
One of the main advantages of mobile mapping is its ability to collect data quickly and accurately in a wide range of environments. This makes it particularly useful for field surveys, asset management, and emergency response, where data needs to be collected quickly and efficiently.
Drones are one of the newest additions to the types of gis data capture tools that experts have added to their tool bags. As they’ve become more accessible, using drones for collecting GIS data has become more and more popular. One of the main advantages of using drones for GIS data collection is their ability to access areas that may be difficult or impossible for humans to reach. This can include remote or hazardous locations, such as disaster sites or steep mountain slopes.
Using specialized sensors and imaging equipment, drones can capture high-resolution aerial photographs and video footage, as well as other types of data such as elevation information and thermal readings. Drones can also be equipped with GPS technology, allowing for precise location tracking and mapping. Using drones for GIS data collection can be an efficient and cost-effective way to gather detailed information about a given area.
