A raster grid format is a data model for satellite data and otherremote sensingdata. For raster positions, it’s simple to understand cell size. Map algebrawith raster data is usually quick and easy to perform. Overall, quantitative analysis is intuitive with discrete or continuous rasters. Wha...
Vector data is a representation of the world using points, lines, and polygons. This data is created by digitizing the base data, and it stores information in x, y coordinates. Vector data is one of two primary types of spatial data in geographic information systems (GIS) – the other ...
Vector data represents geographic features as discrete points, lines, and polygons.It has a geometry-based structure in which each element in vector data represents a discrete geographic object, such as roads, buildings, or administrative boundaries. Vector data is scalable without loss of quality ...
A lesser-known data type, vectors, has seized the spotlight recently as an enabler of generative AI. But vectors—and databases tuned to store and analyze them—have been toiling backstage for many years. They’re used in geospatial mapping and analysis for city planning, transportation logistics...
GIS Data Models The real world can only be depicted in a GIS through the use of models that define phenomena in a manner that computer systems can interpret, as well perform meaningful analysis There are two significant model categories at present: Graphic Models: Vector and Raster Database Mod...
Multi-scale representation of spatial data is a research focus in GIS, while building multi-scale data model is a key to implementing multi-scale representation of vector data. In view of the shortcomings of existing multi-scale data model in geographical cognition and special analysis, this paper...
基于WebGIS技术的湖泊信息资源共享 There are basic management and spatial analysis functions to lake database in the lake information system based on WebGIS. They are mainly: editing and ... 江南,施晶晶,吕恒 - 《地理学报》 被引量: 17发表: 2002年 Data Security Analysis of WebGIS Based on Ti...
a raster-basis. However, sometimes landscape information come along in vector-formats. For the calculation of landscape metrics, one must perform a vector-to-raster-transformation often resulting in a lost of information. In VLSM we implemented the following landscape metrics based on vector data: ...
aData extraction is a GIS process similar to vector overlay, though it can be used in either vector or raster data analysis. 数据提取于传染媒介覆盖物是一GIS处理相似的,虽然可以用于传染媒介或光栅数据分析。 [translate] 英语翻译 日语翻译 韩语翻译 德语翻译 法语翻译 俄语翻译 阿拉伯语翻译 西班牙语翻译...
