How to Rename attribute fields & Rearrange attribute fields in QGIS Refactor fields Refactor fields, allows editing the structure of the attribute table of a vector layer. Fields can be modified in their type and name, using a field’s mapping. The original layer is not modified. A new layer is generated, which contains a modified attribute table, according to the provided fields mapping. Refactor layer fields allows to: Change field names and types Add and remove fields Reorder fields Calculate new fields based on expressions Load field list from another layer Add Vector Layer to Layers panel to Drop field(s) Choose Processing → Toolbox → Vector table → Refactor fields Figure 178 - Vector layer with attribute table before Refactor fields Select Input Layer (Ex: Ind_adm1) Select fields to be renamed and reorder (Ex: in the below given example Name_0 has to rename as Name with Length from 75 as 100 and change order of Name_1 under Name_0 [Name after rename] ) Figure 179 - Fi...

What is Survey Of India (SOI) Framework?

What is Survey Of India (SOI) Framework? The Survey of India (SoI) framework is a geospatial reference system used in India for mapping, surveying, and geodetic purposes. The framework is maintained by the Survey of India, which is the national mapping organization of India and the oldest scientific department of the Government of India. The SoI framework is based on the Indian Terrestrial Reference Frame (ITRF) and the Indian National Spatial Reference System (IN-SRS), and is used to determine the location and height of points on the Earth's surface with high accuracy. The framework is also used to define the horizontal and vertical reference systems for mapping and surveying purposes in India. The SoI framework provides a consistent and accurate basis for various geospatial applications, such as land management, urban planning, navigation, disaster management, and environmental monitoring. The framework is also used for the production of topographic maps, cadastral maps, and othe...

What is the difference between IGS & CORS?

What is the difference between IGS & CORS? IGS (International GNSS Service) and CORS (Continuously Operating Reference Stations) are related but distinct concepts in the field of GNSS (Global Navigation Satellite System). IGS is a global organization that provides GNSS data and products, while CORS is a network of GNSS receivers that provide real-time data for surveying, mapping, and geodetic applications. CORS stations are typically installed at permanent locations and continuously collect data from GNSS satellites, which is then transmitted to a central server and made available to users through the internet. The IGS operates its own network of GNSS stations, which it uses to generate precise orbit and clock solutions for GNSS satellites, as well as precise coordinates for GNSS stations. The data and products generated by the IGS are used for a variety of purposes, including navigation, surveying, mapping, geodesy, and scientific research. In summary, IGS is an organizati...
