The two primary types of spatial data arevector and raster datain a GIS. But what is the difference between raster and vector data? When should we use raster and when should we use vector features? Find out more about the spatial data models commonly used. Vectors are points, lines, and ...
People use GIS to create maps, graphs, diagrams, and charts that can help them visualize processes, outcomes, and other information. While GIS can be used to create maps, it’s best known for its ability to processspatial dataand analyze data about locations, like where things are located o...
KML files store geospatial data. KML files provide information to the relevant software regarding the features such as place marks, images, polygons, 3D models, and textual descriptions. These features are always incorporated with a specific coordinate on the map, often given by longitude and latit...
raster datavector datametadatageospatial data setMODFLOWA geographic information system (GIS) was used in developing a graphical user interface (GUI) for use with the U.S.Geological Survey's finite difference ground-water flow model, MODFLOW. The GUI permits the construction of a MODFLOW based ...
GIS data modeling offers a wide range of types compared to CAD. For vector data in GIS, you can work with network datasets, linear referencing systems, and topological networks. Additionally, raster data have complex data storage from mosaic datasets to multidimensional rasters. But CAD systems ...
KMZ and KML are both file formats for storing geographic data in Google Earth. Today, we’ll explain thedifferences between KMZ vs KML. We’ll also show you how to convert them into both file formats. Are KML and KMZ files the same?
Based on Sentinel data with a resolution of 10 m, the NDVI difference method was used to extract rice fields between 2019 and 2023. Furthermore, the reasons for changes in rice fields over the five years were also analyzed. First, a simulation model of the rice harvesting period was ...
