Release Notes

iXGIS Update: V1.0 Official Release (2026-03-28)​

  1. iXGIS has completed development of the official V1.0 release and has started paid subscriptions. The Professional edition is CNY 299/year, and the Advanced edition is CNY 499/year. Monthly subscriptions are also available. Users can start with the Free edition and purchase the Professional or Advanced edition when more features are needed.

  2. Added Tianditu point of interest (POI) search to help users quickly locate project areas. Search results can be saved as point features for later buffer analysis, overlay analysis, layout-based map production, or attribute organization. Details.

  3. Added vector data conversion tools to the Geoprocessing Toolbox. These tools can export iXGIS vector data formats (pgv, gpv, and shp) to other formats, and convert other formats to iXGIS vector data formats (pgv, gpv, and shp).

  4. Added raster data conversion tools to the Geoprocessing Toolbox. These tools can export the iXGIS GeoTIFF raster format to other formats, and convert other formats to the iXGIS GeoTIFF raster format.

iXGIS Update: V0.9 Release (2026-02-27)​

This release includes major changes, summarized by section below.

Refactored the Toolbox Front-End Framework​

  • Previously, all toolbox services were driven by the Python back-end service. When the number of tasks increased, the interface could become slow. Task submission is now managed by the JavaScript front end, while the Python back end focuses on computation.
  • Changed the toolbox window from a pop-up window to an expandable side panel, improving the UI on small screens, especially on macOS.
  • Refactored error messages in the toolbox interface and added validation before running tools.
  • Refactored AI-based toolbox computation. It now has two modes: in GEOAI-UI mode, AI tends to use existing toolbox tools to meet user requirements; in GEOAI-Code mode, AI tends to write code to solve the problem.
  • Added automatic renaming for toolbox output files. The naming rule is input_file_tool_id.extension.
  • Redesigned the raster calculator and vector calculator using ideas from Excel-style function calculation, making them easier to use.
  • Reworked common toolbox options. Raster and vector outputs now share nearly universal output options. Raster tools added Snap Raster support, making it easier to process multiple rasters into a consistent raster grid.
  • Snap Raster: aligns the output raster to an existing raster so that cell boundaries and cell centers fall on the same grid. For example, two rasters may both use 30 m resolution but still be offset by half a cell because their origins differ. If the origins differ, the rasters cannot be subtracted, divided, or combined cell by cell even when their resolutions are the same. When Snap Raster is used, raster size, cell size, extent, and valid value range cannot be changed and remain consistent with the source raster.

Toolbox Tool Updates​

  • Fixed bugs in multiple toolbox tools.
  • Added several data processing tools.
  • Added data download tools, including satellite imagery download, surface data download, and Tianditu administrative region download.
  • Satellite imagery download tool: downloads multiple Tianditu maps and imagery layers.
  • Surface data download tool: downloads basic surface raster data. See the surface data download tool documentation for details.
  • Tianditu administrative region download: downloads Tianditu administrative regions at national, provincial, city, and county levels. See the tool documentation for details.

General Improvements​

  • Added single-point vector data, separated from the previous multi-point vector data.
  • Added a single-precision floating-point field type for vector data.
  • Improved labeling for multipart features.

iXGIS Update (2025-12-18)​

iXGIS added all WMTS layers provided by Tianditu, including global boundaries, terrain, imagery, maps, and the corresponding terrain annotations, imagery annotations, and map annotations. Other models will be connected gradually.

WFS layers and place-name search services from Tianditu will be added later.

iXGIS Update (2025-12-13)​

  1. Added multi-feature rotate and scale support for vector editing. Users can specify a scale factor and rotation angle while keeping free rotate and scale behavior available.
  2. Added solid-color transition color schemes, including magenta, cyan, blue, green, gray, and corresponding gradient schemes.
  3. Standardized the term angle as azimuth, with the unit deg. Fixed-angle operations were renamed to fixed-direction operations.
  4. Updated the Move To function. Calculation now uses the current project coordinate system, and longitude and latitude input supports both DD and DMS formats.

iXGIS Update (2025-11-25)​

  1. Fixed field calculation issues in table data.
  2. Fixed drift after bitmap georeferencing.
  3. Fixed multipart feature splitting issues.
