Module Introduction

New Features

10i(2021) SP1

Fix several bugs, details

10i(2021)

Supports browsing and retrieval of image (grid) data published by iServer image service
API for slicing, legend, statistics, etc

10i(2020) SP3

Fix several bugs, details

10i(2020) SP1
iClient for OpenLayers update

WebMap supports graticule, the unique value thematic map supports custom styles, and the data stream layer supports the Mercator coordinate system

10i(2020)

Provide online examples of geographic machine learning services such as binary classification and object detection

Provide multiple component configuration interfaces, and print out GeoPDF format files online

The visible range of the specified layer can be controlled according to the geometry

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

10i SP1

Support modular development and improve application maintainability

Support to acquire and update map, data, service, dashboard, insights and other resources of Resource Center

9D(2019)

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.

Docked the latest ECharts 4.1.0, added increment rendering capabilities, supports visual rendering of data at ten millions of data level.

Support for Mapbox Vector Tile (MVT) open standards based on Mapbox GL JS, OpenLayers, etc.
Interactive, online editable map style.and changing styles do not require anti-copying and re-slices
Support Web Mercator, WGS84, China2000,etc.

Optimized API documentation
Organized document content, optimized document display format, improved interface parameters and their usage descriptions
Greatly improved document readability and usability

9D SP1

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/@supermap/iclient-openlayers

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 ECharts visualization layer

Add label thematic map layer at the client side

Support thematic map in the WebMap

9D

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

Support 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, 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
