The Point Sampling Tool is a QGIS plugin designed to extract raster band values and polygon attributes at specific point locations. This QGIS plugin functions as a utility for geospatial data processing, enabling users to perform precise sampling operations across complex datasets. It integrates directly into the software interface to capture values from raster layers or polygon attribute tables, mapping this data onto a new or existing point layer. The tool is engineered for technical accuracy in geographic information systems, ensuring that point-based analysis remains consistent with underlying grid or vector data sources. Its architecture supports standard GIS workflows, facilitating the correlation of diverse spatial information into a singular, manageable point-based format for subsequent analysis.

The download is a 31 KB file containing .ZIP files.

To utilize this plugin, install it via the QGIS plugin manager to enable its functionality within the workspace. Once active, define the input point layer and the target raster or polygon source files within the plugin dialog. The tool automatically maps the attributes based on coordinate alignment, creating a new point layer populated with the sampled values. This automated process replaces manual attribute assignment, significantly reducing the time required for large-scale spatial data preparation and site analysis.

Professionals working in urban planning, landscape architecture, and environmental consultancy use this tool for site analysis and feasibility studies. It is essential when extracting elevation data from digital terrain models or identifying site-specific attributes from zoning maps. Architects and surveyors rely on this plugin to streamline the integration of geographic datasets into project planning, ensuring that site-specific environmental or regulatory data is accurately captured. It is particularly useful for projects requiring detailed analysis of existing site conditions before design development begins.
