Project requirements, so there are some customer data, the data is contained geographical location information, for example, some location acquisition of pm2.5. The rainfall, the path of a sprinkler, have spilled water,

Customers hope to be able to achieve such effect, combined with the client area, their data visualization in the area of the map, for customer's analysis,


So, the research contents of the GIS, but not sure where to start, just find a lot of technical framework or products, arcgis, QGIS, openlayers, echarts, geoserver, etc.,


Question:

1 what is generated by the map?
Is based on the administrative area of geographic data, the algorithm automatically generate 2 d or 3 d map? Or the use of arcgis, QGIS such tools, by human editors out a map picture?

2 when have a map of the area of complete, so what is the tile of the generated?

3 what role openlayers? The tiles generated from 2, shown in the front-end web browser? Or can have the effect of 1?

4 other types of data, it is necessary to combine together for visualization map those data, use openlayers can achieve? Still need to use similar echarts antv framework implementations such as?

5 maps and visual chart is how to present in the browser? What kind of framework? Or which using implementation framework?
