In the realm of Reality Capture, Reality Mapping, Imagery, and Remote Sensing, having access to quality LiDAR, DTM (Digital Terrain Models), and DEM (Digital Elevation Models) data is crucial. Arkadiusz … Read more
Contour lines are lines that connect points of equal elevation on a map, allowing the terrain’s relief to be visualized. A DEM (Digital Elevation Model) is a raster representation of … Read more
QGIS2threejs is an extension of QGIS (an open-source GIS platform) that allows for exporting QGIS maps to 3D format using the JavaScript library Three.js. The extension adds a new tool … Read more
Cadastral surveying is a process that involves a detailed and comprehensive inventory of real estate assets in a particular territory. This inventory includes the identification, location, description, and valuation of … Read more
Creating a Digital Elevation Model (DEM) from contour lines is a fundamental process in GIS analysis, which allows us to create 3D models of the terrain. In this blog, we … Read more
In this tutorial, we will go through the steps required to delimit hydrological basins using GRASS GIS, including setting up the software, importing data, installing plugins, correcting depressions in the … Read more
Geographically Weighted Regression (GWR) is an interesting method with many applications. GWR is different from other techniques because it allows the relationships between covariates to vary spatially. For some research … Read more
A fairly common problem is usually the access to spatial information, in this case Digital Elevation Models (DEM) are not always available to everyone, either by cost, availability, or lack … Read more
A watershed is an area of land that captures water, which eventually flows through a single point or outlet such as rivers, reservoirs, and the ocean. QGIS 3 has a … Read more
A watershed is an area where water that falls or flows across the surface of the land drains into a stream or river, and eventually flows through a single point … Read more
Contours are lines connecting points of equal value that represent continuous phenomena (Huisman & A. de By, 2009). Contours are called isolines, but may also have specific terms depending on … Read more
