전체 글30 [QGIS Intermediate] Editing the Attribute Table of a Vector Layer Hello, In this post, I will discuss how to edit the attribute table of a vector layer to suit your needs. The editing we'll cover in this content includes adding, deleting, and modifying data. Unlike raster layers, which do not provide editable attribute tables, only vector layers' attribute tables can be modified. Let's start by downloading the Vietnam border map from the following link for exa.. 2024. 4. 19. [QGIS Beginner] Toggle Editing Mode (for Vector Layer) Hello, In this post, we'll explore how to activate the Toggle Editing mode to make a vector layer editable. Activating the Toggle Editing mode essentially means making the vector layer editable. If Toggle Editing mode is not activated, you won't be able to use features like modifying fields in the attribute table or drawing new polygon files using the Add Polygon feature (Ctrl + .). Let's first .. 2024. 4. 16. [QGIS Basics] Adding Labels for each Field Hello, In this post, we'll explore the use of the label feature to display field values on a map. Typically, when we look at a map, as shown below, the names of regions are displayed as text. Using the label feature, we can also display the data values we want to represent alongside these region names. Source: Google Maps Once again, let's download the Vietnam border map from the following link .. 2024. 4. 12. [QGIS Basics] File Conversion (Raster -> Vector) Hello, In this post, we'll delve into the most fundamental aspect of file conversion, even among the basics. Fundamentally, vector files and raster files can be converted between each other, allowing rasterization (vector to raster) and polygonization (raster to vector). Often in GIS tasks, there are functionalities that can only be applied to vector layers, and conversely, there are functionali.. 2024. 4. 8. [QGIS Basics] Refactor Fields - Changing the Field Type Hello, In this post, we'll explore how to change the field types within the attribute table of a layer. A "field" refers to the group of values that appear when you open the attribute table of a vector layer in QGIS. Think of it as columns in Excel. QGIS software provides the functionality to change the type of each field to various types such as Text, Number, etc. To illustrate this, let's load.. 2024. 4. 4. [QGIS Intermediate] Combining Spatial Data and Attribute Table Hello, In this post, we'll explore how to combine spatial data and attribute table using QGIS. Here, spatial data refers to map data with X, Y coordinates or already polygonized map data in formats like shapefile, while attribute data refers to text-based data like Excel data that hasn't been spatialized yet. If you have Excel values with all geospatial information and corresponding spatial data.. 2024. 4. 2. 이전 1 2 3 4 5 다음
