As we all know that WebGIS has reduced the cost of learning and deploying GIS software to a certain extent. However, users usually meet some problems like the incomplete function of GIS in application resulting in the interruption of workflow and the difficulties in communicating the results among the applications. It has hindered the realization of web in geospatial information platform.
MapStudio is a brand-new WebApp. Besides mapping, it can access to existing maps and carry out secondary mapping, and supports spatial analysis. In technology, MapStudio adopts rendering mechanisms that different from DataViz to carry more data and present richer rendering effects.
Smoother Web map rendering
With the popularity of sensors and various types of digital terminal equipment, the number of location data is growing explosively. Then, how to smoothly render those massive data to bring users a better map browsing experience is an urgent challenge to Web maps. Major GIS and Internet manufacturers have proposed and adopted vector tile rendering technology as one of the main solutions. Among them, Mapbox Vector Tile (MVT for short) proposed by Mapbox is the most representative. Vector tile has smaller volume and faster rendering than grid tile. In the way of data loading, the vector tile only loads the content within the visual range, which can further improve the display efficiency of the map.
More plentiful and flexible layout selection
In MapStudio, users can not only set the display style of the accessed data in the map, but also use the map service or vector tile service published in SuperMap iserver for secondary mapping. The drawing option of MapStudio follows the Mapbox style specification. which can achieve more plentiful map styles than DataViz. Besides the basic configuration of color, width, size, opacity, there are also a variety of detailed configurations. In addition, part of the configuration adopts a more intuitive icons to express options and improve the operation experience.
The thematic map of MapStudio can be used to quick display a certain character of map features. Users can set unified icon shape, size and opacity for all classification, and then set different colors for every classification by the built-in color bar. Besides, the style setting of every classification is also available.
Interactive online spatial analysis
Spatial analysis is one of the important ways to help people quickly discover the potential value of data. providing online spatial analysis is another big improvement of MapStudio compared with Dataviz. In real projects, spatial analysis and style configuration of analysis results are closely related steps. Therefore, MapStudio can meet the needs of users with higher mapping requirements.
MapStudio provides overlay analysis, area summary, grid summary and data summary. The analysis results can be visualized, including modifying the layer style of the analysis results and quickly making thematic map, which makes the spatial distribution rules and association rules more intuitive.
More convenient 3D map making
Comparing to 2D maps, 3D maps can express space things more intuitively and vividly, and more in line with people's cognitive habits. In MapStudio，users can quickly make 3D map even without the model files. The stereoscopic map shown below can be generated by stretching the specified height attributes of accessed polygon data. Users can also adjust the view angle of the map or rotate the map to browse the map in multiple directions by dragging the map with mouse.
Results normalization and map sharing
In order to make the map produced by mapstudio to be shared and used in SuperMap product system more easily, the R&D team of mapstudio has developed WebMap 3.0 specification to describe the map information. WebMap 3.0 has the similar concept with the traditional Meb map service, which is to provide web accessible maps to clients. The difference is that the production of WebMap3.0 does not need to go through the server service publishing process, the map saved in MapStudio is published.
