Newly added features in history versions

Vector Tile

• Added MVT, and provide online and offline method to loading MVT data.
• Added MVT Supported style to dynamically modify, load, and save.
• Optimized GL vector tile data storage structure, which decrease the data storage space and cutting time.
• Optimized GL vector tile display, which repair problem of broken line, text flashes and gland along the line.

Enhancements of Map Function

• Added AR map. Supported the overlay of map and real scene, and locate the target quickly.
• Added map roller blinds function.
• Optimized TIFF browsing performance.
• Optimized IMG browsing performance.
• Optimized image data overlay vector data browsing performance.
• Optimized web map overlay vector data browsing performance.
• Added an interface of setting node style of edited objects.

Enhancements of Data Engine

• Supported import of empty SHP dataset.
• Added function of open TIFF as datasource directly.
• Added function of open IMG as datasource directly.
• Added function of DCT compression. Provides a fast and lossless compression method that enables HD images to be smaller.
• Added image Pyramid constructed by TIF and IMG, which enhanced image data display.
• Supported fault-tolerant processing of SHP data illegal fields.

Enhancements of Plot Function

• Supported the creation of graphic objects.
• Supported Addeding graphic objects into map.
• Supported updating graphic objects.
• Supported import and output of graphic objects as GeoJson.

Enhancements of 3D Function

• New AR (Augmented Reality) feature in the 3D special effects, Supported motion tracking, region recognition, and integrates virtual 3D plane scenes with real world .
• The rendering engine is upgraded to OpenGLES 3.0, which Supporteds rendering and rendering instantiated objects, reducing memory usage.
• A planar scene that Supporteds loading data from a planar coordinate system and a projected coordinate system.
• Supported loading large file format TIN terrain, oblique photogrammetric model, S3M 3D tile data, improving copy data to mobile device efficiency, and enhancing data loading performance.
• Cubic box clipping, plane clipping, and Cross cutting.
• Supported point cloud data for S3M 3D tiles and Supporteds layered coloring.
• Improved the stability of the scene switching to the background of the system.

Optimization of OpenGL Display Engine

• Reconstruct OpenGL text display mechanism, and enhanced the supported of big data text.
• Repaired the situation that some equipment cannot display text or text file is unstable while using OpenGL mode.

Distributed Analysis Service

• Adjust the default parameter to prevent the user from forgetting to set some necessary parameters, resulting in analysis failure.
• Optimized network requests and callbacks to improve service stability.
• Added buffer analysis, and supported buffer analysis by setting buffer distance, distance unit and so on.
• Added grid index analysis.
• Added overlay analysis, and Supported overlay analysis by setting datasets, analysis mode and so on.
• Added feature connection analysis, and Supported the set of connection method, dataset, field, distance and tolerance.
• Added topographic analysis, and Supported topographic analysis by setting topographic dataset and rules, etc.
