Manually delineating a watershed by analyzing contour lines or interpreting topographic maps is a time-consuming process that requires advanced knowledge in hydrology and topography. This method involves identifying ridge lines and tracing the watershed boundaries, which can lead to approximate… Read more: Watershed Delineation Using ArcGIS Pro - Using the Raster Calculator Tool in ArcGIS Pro
The raster calculator is a tool that allows for the performance of operations and algebraic expressions using various tools and operators through an interface similar to a basic calculator. This tool is versatile and powerful, making it suitable for conducting… Read more: Using the Raster Calculator Tool in ArcGIS Pro - Viewshed Analysis Using the Geodesic Viewshed Tool in ArcGIS Pro
Viewsheds are areas of terrain visible from a specific location, such as a mountain, building, or observation point. They are commonly used in landscape analysis and urban planning to determine which areas are visible or not visible from a particular… Read more: Viewshed Analysis Using the Geodesic Viewshed Tool in ArcGIS Pro - Generating a Hillshade Map in ArcGIS Pro
A shadow map is a shading technique used to highlight the topography of a specific area. This method simulates the position and intensity of sunlight on the terrain, producing an image that differentiates between illuminated and shaded regions. The result… Read more: Generating a Hillshade Map in ArcGIS Pro - Using the Reclassify Tool in ArcGIS Pro
The “Reclassify” tool has the capability to modify the values of a raster by replacing existing information with new values. This is applicable to any variable stored in raster format, such as slope, elevation, precipitation, temperature, among others. To conduct… Read more: Using the Reclassify Tool in ArcGIS Pro - Generating Contour Lines Using a DEM in ArcGIS Pro
Contours, also known as isolines, are lines that connect points of equal value and are used to represent continuous phenomena. Isolines may have specific names depending on the phenomenon they depict. For example, when representing elevation, they are referred to… Read more: Generating Contour Lines Using a DEM in ArcGIS Pro - Generating a Slope Map
Slope is a key factor influencing the configuration of Earth’s relief. Its analysis is essential in disciplines such as geomorphology, hydrology, cartography, and land planning. Slope refers to the inclination of the Earth’s surface between two points at different elevations.… Read more: Generating a Slope Map - Digital Elevation Models (DEM)
A Digital Elevation Model (DEM) is a raster-format representation of a continuous surface used to describe Earth’s topography. These models are composed of a series of points, each defined by “X”, “Y”, and “Z” coordinates within a specific spatial reference… Read more: Digital Elevation Models (DEM) - Spatial Interpolation in ArcGIS Pro
Tobler’s first law of geography (1970) states, “Everything is related to everything else, but near things are more related than distant things.” For example, if it rains on one side of a street, it is highly likely to rain on… Read more: Spatial Interpolation in ArcGIS Pro - Projecting a Layer to a Different Coordinate System in ArcGIS Pro
The “Project” tool is used to transform spatial data from one coordinate system to another. This process involves changing the projection of a layer, for example, from the “WGS 1984 UTM Zone 17S” system to the “Provisional South American Datum… Read more: Projecting a Layer to a Different Coordinate System in ArcGIS Pro - Defining the Coordinate System of a Layer in ArcGIS Pro
When new layers are added in ArcGIS Pro, such as the “no_projection.shp” file, a warning may appear indicating: “Unknown Coordinate System ‘Map2’ data source is missing coordinate system information. Click here to view details.” This means that the added layer… Read more: Defining the Coordinate System of a Layer in ArcGIS Pro

- 40 GIS Research Ideas to Shape the Future of Spatial Analysis and Decision-Making
Geographic Information Systems (GIS) have emerged as a powerful tool in spatial analysis, environmental monitoring, and decision-making across various fields. From urban planning to climate change studies, GIS enables researchers and professionals to collect, visualize, and analyze geographic data in ways that were previously unimaginable. The integration of GIS with… Read more: 40 GIS Research Ideas to Shape the Future of Spatial Analysis and Decision-Making - HEC-RAS 2025 Release: A New Era in Hydraulic Modeling
The Hydrologic Engineering Center (HEC) of the U.S. Army Corps of Engineers has announced the alpha release of HEC-RAS 2025, marking a significant milestone in the evolution of hydraulic modeling software. This new version represents a complete reimagining of the River Analysis System, built from the ground up to meet… Read more: HEC-RAS 2025 Release: A New Era in Hydraulic Modeling - The Phases of the Moon
The Moon’s phases are a result of the varying amounts of its surface illuminated by sunlight that we can see from Earth. This changing visibility gives us the lunar phases. The Moon Reflects Sunlight The Moon does not emit its own light but reflects the light of the Sun. As… Read more: The Phases of the Moon - Latitude and Longitude
Latitude and longitude are fundamental concepts in geography and navigation, helping us pinpoint any location on Earth. When you look at a map or a globe, you’ll notice lines running horizontally and vertically. These lines form a grid system that allows for precise location identification. What is Latitude? Latitude lines… Read more: Latitude and Longitude - Earth’s Rotation and Revolution
Grasping the concepts of Earth’s rotation and revolution is essential to understanding many natural phenomena that impact our daily lives. These movements explain why we have day and night, changing seasons, and a host of other important effects. Earth’s Rotation: The Basics Earth’s rotation refers to the spinning of the… Read more: Earth’s Rotation and Revolution
