Vector data uses points, lines, and polygons to represent features, while raster data uses a grid of cells to represent data.

• Vector data is used for representing discrete features such as roads, buildings, and rivers.

• Raster data is used for representing continuous data such as elevation, temperature, and precipitation.

• Vector data is more precise and accurate, while raster data is more efficient for large areas.

• Examples of vector file formats include Shapefile, GeoJSON, and KM...read more

GIS can be categorized into desktop, web-based, mobile, and cloud-based. It is used for mapping, spatial analysis, and decision-making.

• Desktop GIS: used for complex analysis and data management

• Web-based GIS: used for sharing and accessing data online

• Mobile GIS: used for data collection and fieldwork

• Cloud-based GIS: used for scalable and collaborative projects

• GIS is used in various industries such as urban planning, environmental management, and emergency response

• Examples: Arc...read more

Python libraries for GIS include GeoPandas, Shapely, Fiona, PyProj, and Rasterio.

• GeoPandas: for working with geospatial data in Python

• Shapely: for manipulating and analyzing geometric objects

• Fiona: for reading and writing geospatial data formats

• PyProj: for converting between geographic and projected coordinates

GIS stands for Geographic Information System, which is a computer system for capturing, storing, analyzing, and displaying data related to positions on Earth's surface.

• GIS is used to create maps and visualize spatial data

• It can be used in various fields such as urban planning, environmental management, and emergency response

• GIS combines layers of information to give a better understanding of a location, such as population density, land use, and natural resources

• Examples of GI...read more
