Vector Map Packages

• Provide the function of reading the vector map package, and support opening the vector map package data of SuperMap format, which greatly improves the display performance of the vector map.

Data Collection and Edit

• Add topological editing functions, and support construct region by topology, point splits region, region splits region, combine regions, merge regions, fill islands and holes, supplement islands and holes, region intersect.
• Add object editing features, and support translating objects, selecting objects by dragging a box, selecting multiple objects, delete objects in batch.
• Add topological snap function, and support endpoint snap, node snap, point snap and snap along the line.
• Fix the problem that the self intersected region cannot be drawn while calculating area.
• Fix the problem that the redo function cannot work during the editing of region objects.

Map Display Engine Optimization

• Support map rotation.
• Support map pitch display.

Dynamic Charts

• Provides dynamic charts for big data presentation, supporting pie, polyline, bar charts for the display.

Indoor Navigation

• Provide the integrated map display for indoor and outdoor navigation.
• Provide display function of indoor map, supporting the switch between floors.
• Provide indoor path analysis function, and support multi-point, cross-floor path analysis.
• Provide indoor path guidance function.

Image Data Operations

• Provide the TIFF format image data import and export function, and support importing the TIFF format file as a dataset and exporting the image dataset into the TIFF format file.
• Provide the stretching function for TIFF format image data, and support 6 kinds of stretching methods: standard deviation stretching, extreme value stretching, the Gauss stretch, the histogram stretch, the histogram equalization stretch and none stretch.
• Provide the clipping and cutting function of the TIFF format image data, and support clipping and cutting the image dataset into new datasets.

Enhancements of Map Functions

• Add map precache function for network map precache. Support REST service map and SuperMap Cloud map. You need to open a map and a web map datasource before caching data, specify a rectangular bounds for the web map dataset, and cache all data within the bounds to the SD card of the mobile device for offline browsing.
• Add layer management control for controlling and managing layers of maps.
• Add funtion of user bounds. If the bounds have been specified, any operations beyond the bounds will be invalid.
• Add support of maximum and minimum scales for maps. If set, the map cannot exceeds the specified scale range.
• Add support of fixed scales for maps. If set, maps can only be zoomed in or out among the specified scales. The map will not display at a scale that is not in the list of scales specified by the user.

Dynamic Layer Optimization

• Add boundary style setting function for dynamic region objects.
• Add label and label style setting function for dynamic objects.
• Dynamic elements support long press events.
• Dynamic layer objects support displaying, hiding objects and setting the transparency of objects.
• Support time series data.

Enhancements of Data Engine

• Support AutoCAD data format. Support importing and exporting DWG, DXF format data.
• Support KML files. Support importing and exporting vector datasets into KML files.
• Add function for deleting dataset fields.
• Add function for creating spatial index.

Enhancements of Analysis Functions

• Support 3D network analysis function, providing three-dimensional traffic network analysis and three-dimensional facilities network analysis function.

Enhancements of 3D Functions

• Support 3D layer of the tile map network service (WMTS) type.
• The online base maps are richer: support adding Tianditu map data services, iServer services, and STK world terrain terrain services.
• Support TIN terrain data. The performance of terrain download efficiency, display effect have been greatly improved. Moreover, image loading, terrain excavation, terrain translucent display and other functions are now supported.
• Support zoom the 3D scene to the ground surface to perform the pitching operation, improving the user's operation experience.
• Support scene restore, which helps avoid scene crashes after loading online maps.
• Support RGBA color mode, and OSGB cache layer allows transparency settings.
• Support first person camera, panning the scene to provide camera following function.

3D Symbolization

• Supports the use of icon files in PNG format to represent point geometry objects in a 3D scene.
