Build a geo indexing mapping software

Looking to have a spreadsheet or other form of data set that has gps based coordinates behind a linked name , say a cemetery location (Whitmire Cemetery, that can be sent through a trigger or manually to start, to a map that geo-indexes these locations to show coordinates of different locations, so that we can date color each location for job scheduling, such as, each job starts at green for date of production being early to red for date of production being close to deadline, or late. This would allow us to create a service schedule based on job density around a certain location and allow us to cluster these jobs as we see more “aging” jobs in a certain area: basically dates and location, mapped out with GPS coordinates and color coded for date aging.
