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...

Exercise – 12 / How to Create GRID in QGIS Create Grid Generate a line or polygon grid based on user-specified grid spacing. Add Polygon/Line/Point Layer to Layers panel for creating GRID Figure 150 - QGIS canvas with polygon layer added for creation of GRID Choose Vector →Research tools →Create Grid Select Grid Type (Point / Line / Rectangle / Diamond / Hexagon) Select Grid extent (Use canvas extent / select extent on canvas / use layer extent) Suggestedto select use layer extent and select the layer and click on OK . Provide Horizontal spacing in meters / kilometers / feet / miles / yards Provide Vertical spacing in meters / kilometers / feet / miles / yards Provide Horizontal overlay in meters / kilometers / feet / miles / yards (if required only, or else leave as 0) Provide Vertical overlay in meters / kilometers / feet / miles / yards (if required only, or else leave as 0) Select Grid CRS Click on Run Temporary layer will be created and added to Layer panel with Grid ...

Exercise – 13 / How to add Geometry to Attributes in QGIS తెలుగులో నేర్చుకుందాం

Exercise – 13 / How to add Geometry to Attributes in QGIS Add Geometry Attributes. The geometry tool is an easy to use tool that allows you to add the following geometry values to points, lines, and polygons: Point: The XCOORD and YCOORD columns will contain the x and y coordinates of the point Line: The SHAPE_LEN column will contain the length of the record's line(s) Polygon: The AREA and PERIMETER columns will contain the area and perimeter of the record's polygon(s). Add Geometry Attributes for Point. Add Point Layer to Layers panel Figure 134 - Point layer for adding geometry Open attribute table Figure 135 - Attribute table before adding geometry Choose Vector → Geometry tools →Add Geometry Attributes Figure 136 - Add geometry attributes window for Point Select input layer (Ex: Ind_Point) Select CRS from (Layer CRC / Project CRC / Ellipsoidal), better to select Layer CRS Click on Run Temporary layer will be created and added to Layer panel with Added geom info ...
