Mapping Tool for Geospatial Data (Millions of records, MapBox experience a HUGE plus)

Full Project Described in attachment. Summary here: We need a map for end users of oil and gas data. We will provide you with a single table that has everything you need. Latitude, longitude and metadata about each wellbore in the United States. One of the key features will be a “lasso” capability where users can zoom in and draw a shape around a set of wells to select them. This will activate a popup that has every well listed along with metadata (from that same, single table) and hyperlink(s) to our main data store, to do deeper analysis. We have an existing map that is built in MapBox. We currently have not added any customization to the interaction with that map. Our single table will have over 1MM wells (markers) in it. We have seen cases where a user has to zoom in over and over again, before seeing any meaningful data. That’s basically the project. Enter a U.S. map, zoom in, click on a well or draw a circle around some wells. Get some basic information. Get a link to a place with more detailed information. With that said, I have never seen an “entrance” (navigation) map I like. [login to view URL] [login to view URL] [login to view URL] [login to view URL] First thing you will notice? The number of wells is overwhelming. The challenge for our team? How do we build a map with potentially 1.4MM markers on it? And do it in a way that won’t take forever to load.
