There are two technologies that are used for the collection, management, analysis, and understanding of geographical data: Geographic Information System (GIS) and Global Positioning System (GPS). Even though GIS and GPS are employed in conjunction, their functions are not similar. While GPS works primarily to determine the location of a receiver, GIS is used for the purposes of storing, analyzing, visualizing, and managing spatial data. It is important for specialists in surv

Remote sensing is a key technology that allows the gathering of information from the Earth's surface without being in physical contact with the studied areas or objects. This technology is an integral part of Geographic Information Systems (GIS), environmental monitoring, agriculture, forestry, urban planning, disaster management, military operations, and observations related to the planet. Any remote sensing device consists of a remote sensing sensor. The sensor's purpose is

Geospatial technology is now an integral component of modern decision-making processes in such sectors as urban development, agriculture, transport, environment, surveys, military, construction, and disaster management. With the rising amounts of geospatial data collected by businesses, proper documentation of this data has become as crucial as the data itself. Geospatial documentation provides information that is required to know about data sources, their collection methods,

Geographic Information Systems (GIS) require accurate locations. Each point, line, polygon, satellite imagery, drone orthophotomosaic, and spatial database needs to be linked with a coordinate reference system (CRS), which describes how locations on the surface of the Earth should be expressed in coordinates. EPSG codes represent a universal way of referencing such coordinate reference systems. Knowledge of EPSG codes is crucial for GIS software usage, creation and usage of s

Spatial Reference System Identifier (SRID) is the name for a unique numeric identifier used to describe the coordinate reference system (CRS) used in the definition of geographical or spatial data. The use of SRID identifiers is critical in Geographic Information Systems (GIS), databases, maps, and any geospatial application since only coordinates alone cannot define how the positions are referenced on the Earth's surface. The coordinates (-77.0365, 38.8977) could be used to

Satellite images are a primary source of geospatial data used in mapmaking, urban planning, environmental observations, infrastructure management, defense, agriculture, disaster relief operations, and many other fields. With advances in satellite imaging technology, the user community benefits from ever-improving satellite imagery with higher spatial resolution. Sub-meter satellite imagery represents one of the most important definitions of high-resolution Earth observation.

Drone mapping has revolutionized surveying, construction, agriculture, infrastructure inspection, mining, and GIS data collection by enabling high-resolution aerial imaging in a short time. Yet, getting sharp images is just half of the work done. The geolocation of each captured image is critical, as the accuracy of the orthomosaic, DEM, DSM, point clouds, and 3D models depends on it. This is why RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic) positioning methods

The distinction between GPS and GNSS leads to confusion in industries like navigation, surveying, GIS, drone mapping, agriculture, and geospatial positioning. The terms are used interchangeably, but GPS is a satellite navigation system, while GNSS refers to the technology comprising multiple global satellite navigation systems. Grasping the difference between GPS and GNSS is essential if someone wants to choose positioning tools, measure positioning accuracy, or develop appli

GPS (Global Positioning System) has advanced into a vital technology that powers applications from mobile phone navigation to self-driving cars, mapping drones, advanced farming, emergency services, and geographical analysis. Billions of devices rely on GPS daily for instantaneous location information. Most users, however, lack a deeper understanding of how GPS works. This technical guide will describe the science of GPS, describe how satellites establish your location, expla

Urban planning is becoming more and more complex, with cities experiencing rapid population growth and infrastructure issues related to climate change and the need for sustainable development. Traditional urban planning processes have relied on historical data, manual surveys, and limited sources of information. Governments and organizations have often struggled to make timely decisions based on good data because of these challenges. GeoAI provides an answer to these challeng

Geospatial data makes possible everything from interactive web maps and GPS navigation to AI-based spatial analytics and digital twins. Picking a file format is also important because it affects your application's performance, storage costs, and how well the new application will work with other applications and systems, as well as its ability to grow over time. The most common geospatial formats used today are GeoPackage (GPKG), GeoJSON, and GeoParquet. Each of these formats

Selecting an appropriate file format for geographic data will have a drastic effect on how you share the data, the efficiency of analyzing the data, the amount of storage you need to maintain the data, and how easily you can work with data from separate sources. The two most commonly used GIS formats are ESRI Shapefile and GeoJSON. ESRI Shapefile has been the GIS format used by most organizations for many years. However, GeoJSON has become the preferred GIS format for web map

As industries rely more on accurate three-dimensional (3D) spatial information, there are two methods of reality capture dominating the landscape: LiDAR (light detection and ranging) and photogrammetry. Both methods can produce accurate three-dimensional models (3D), digital twin models, topographic maps, and geospatial information, but methods differ significantly in acquisition techniques, level of accuracy, cost, processing workflows, and intended use. If you work in any o

Environmental Monitoring, Urban Planning, Agriculture, Natural Resource Management, and Climate Research all depend heavily on accurate and up-to-date data regarding Land Use and Land Cover (LULC); topographically mapped LULC data is an indispensable means of assessing one or more components of our world’s evolving landscape. Thanks to the rapid advancement of geospatial technologies and satellite imagery, LULC mapping has emerged as one of the most significant means of evalu

In remote sensing and GIS, image quality is key to mapping, analysis, and decision-making. There are basically two types of satellite imagery: high resolution (panchromatic) and low resolution (multispectral). While both types of imagery are useful, neither provides the best balance between spatial detail and spectral accuracy by itself. This is where pan sharpening comes in. Pan sharpening is a common image fusion technique that produces a single image that contains the shar

For experts across numerous sectors such as construction, insurance, government, public safety, and geospatial, the brand Pictometry was often considered the go-to source for high-quality aerial photographs and precise property measurements. Their solution changed the way organizations viewed and analyzed locations from an aerial perspective, and their ability to provide photos of properties taken at an angle (oblique aerial imagery) gives traditional satellite image types, n

Geographic Information Systems (GIS) rely heavily on georeferenced imagery for their primary applications of mapping, spatial analysis, remote sensing, and cartography. Accurately positioning images on the Earth's surface is critical, regardless of the type of image you are using (aerial imagery, scanned maps, drone orthophotos, or satellite imagery). The easiest way to accomplish this task is by using a world file. If you have ever opened a file ending with the extensions of

Rasters are an important part of Geographic Information Systems (GIS), and the choice of the raster format can have a large impact on performance, storage efficiency, image quality, and workflow compatibility.
