Module Introduction
New Features
Fix several bugs, details
Supports browsing and retrieval of image (grid) data published by iServer image service
API for slicing, legend, statistics, etc
Fix several bugs, details
Import SuperMap mapbox-gl-enhance.js, optimize Leaflet's rendering effect on MVT vector tiles, and support common coordinate systems: Web Mercator, WGS84, CGCS2000, Beijing 54, Xi'an 80
Provide online examples of geographic machine learning services such as binary classification and object detection
It supports the display of dynamic targets and their tracks, the addition of punctuation supports the function of setting health value, and the addition of punctuation supports the function of setting custom pictures
PixiJS is an ultra fast 2D rendering engine. The combination of pixijs and Leaflet improves the performance of leaflet in massive icon rendering
SuperMap iServer add webp parameters to the drawing format. The webp format has better image data compression algorithm, can bring smaller map tile volume, and has the same image quality with the naked eye recognition
Support to acquire and update map, data, service, dashboard, insights and other resources of Resource Center
Added open file component, data flow component, address match and features search component, client computation component, distribute analysis component, data service query component
GraphicLayer supports data volume increased from 300,000 to 1 million
The performance is improved to more than 3 times, the rendering of million-point data is able
to be completed within 1 second
Supports multiple data formats such as GeoJSON, TopoJSON, and two-dimensional tables, etc.
Supports style changes
Supports interactive operation, such as property filtering and mouse events, etc.
DataFlowLayer added MapV engine, the performance of drawing Marker is greatly improved
The amount of vector point rendering data increased from 10,000 to 100,000, and the raster
image rendering data increased from 3000 to 10,000
Docked the latest ECharts 4.1.0, added increment rendering capabilities, supports visual rendering of data at ten millions of data level
Flexible and convenient 2D dynamic plotting based on Leaflet gallery
Situational derivation with 7 classic animations
Provide convenient situation map management
Optimized API documentation
Organized document content, optimized document display format, improved interface parameters
and their usage descriptions
Greatly improved document readability and usability
Modularized the code, supporting modularized reference by using import grammar in JavaScript ES6 standard during the development
Release the npm project. The url is: https://www.npmjs.com/package/@supermapgis/iclient-leaflet
Integrate with Turf.js, providing users with calculation ability at the client side such as spatial analysis, topology analysis, equivalent analysis, measure analysis and so on. This makes it possible for a variety of common spatial operations to be done quickly at the client side without connecting GIS services
Buffers, topology validator, overlay geo and summary attributes functions are added in the distributed analysis services
Support the analysis of custom drawing range in vector clipping analysis and single object query analysis
Add D3 layer
Add label thematic map layer at the client side
Support thematic map in the WebMap
Complete the docking of basic services in SuperMap iServer
Support access to SuperMap iServer distributed analysis Services, providing density analysis, grid aggregation analysis, single object query analysis, region summary analysis, vector clipping analysis functions
Support access to address matching services of SuperMap iServer, providing forward matching and reverse matching functions
Support access to SuperMap iServer real time data services
New visual effects of time series heat map and flight monitoring effects based on ElasticSearch
Support Mapbox Vector Tile standard, providing users with more map styles to freely change styles at the client side
Add high efficiency point layer, supporting efficient and fluent rendering of 100,000+ point elements in the browser
Integrate with commonly used ECharts visualization effects: scatter map, migration map, heat map, line map, line effects, polyline chart, histogram, pie chart
Integrate with data visualization Open Source Library MapV, providing the honeycomb map, commuting map, strong boundary map, migration map, dynamic trajectory map, the polygon drawing, line drawing and massive point data drawing functions
Support Integration with OSMBuildings to implement visualization of building stereo effects
New cache switch control to allow users to switch among different versions of cache on clients
Easier access to maps configured in SuperMap iPortal and SuperMap Online by users
