Online Raster and Vector Basemap Comparison in QGIS and Which Is Better for A Mapping Project

Image
There are two types of basemaps. Raster tile basemap and vector tile basemap. The raster tile basemap is pre-rendered, stored on the server, and displayed unchanged by the client. The World Imagery basemap is a good example of a raster tile basemap and an example of a basemap that cannot be displayed as a vector tile basemap. The Vector Tile Basemap references a set of web-accessible vector tile data (points, lines, and polygons) and the appropriate style for drawing those tiles. Vector tile basemaps are used for non-image content. Vector tile layers can be adapted to the resolution of your display device and can be redesigned for multiple uses. Vector tile basemap technology now is supported in latest GIS Software such as ArcGIS Pro and QGIS. There are few vector tile format that have been developed by various company or agency. For example, Mapbox have developed MBtiles and MVT as Vector Tile format, ESRI and Google use Protocol Buffer Format (PBF) for its vector t

Download Soil Moisture Raster Data Directly in QGIS

Soil moisture plays an important role in agricultural monitoring, drought and flood prediction, forest fire prediction, water supply management, and other natural resource-related activities. Soil moisture observations can warn of imminent drought and flood conditions before other  standard indicators are triggered.   As defined in AMS Glossary of Meteorology, soil moisture is "the total amount of  water vapor-containing water in  unsaturated soil." Soil moisture (sometimes called soil water) refers to surface water  in the pores of the soil, not rivers, lakes, or groundwater. Soil moisture levels are determined by a variety of factors other than weather conditions, such as soil type and associated vegetation. Second, soil moisture affects the various dynamics of soil and plants. Surface soil moisture is  water located 10 cm above the soil, and root zone soil moisture is  water  available to plants-generally considered to be located 200 cm above the soil floor.  The amount of
