I was checking the route for nearest police station from my office around 3 PM MT using the Chrome. The  Google Map's street looks so funny and floppy. All the street lines and highways lines were wiped out. The interstate has some brown points, if you zoom in them the point looks like half circle. Which has the bug Google Maps or Chrome? Click on images for bigger picture ! (Missing roads)                                                                  (Missing roads on zoom)                                                                          (More zoom in...)

Interesting talk by Paul Ramsey about the decision process to adopt PostGIS vs other spatial databases at FOOSS4G 2014 Portland, OR. Ramsey, "what do managers need to know before they can get comfortable with the idea of making the move."

National Geodetic Survey (NGS)  developed videos to give you a better understanding of NGS' plans to release new datums in 2022. If you use mapping products or other geo-spatial tools, these videos should also help you find out how you can prepare for the new datums. . It’s a number of years off - but the links explain the changes and provide some initial knowledge that may help you prepare for their advent… This series of short videos, produced in collaboration between NOAA's National Geodetic Survey and The COMET Program, a part of UCAR's Community Programs, provides an introduction to geodetic datums for anyone who uses mapping products or other geo-spatial tools.  In the first video, "What are Geodetic Datums?" (4:36), explains the basic concepts behind geodetic datums, where they are used, and why it is important to know about and use the correct datums.

There are may be several reasons for TypeError:t is null, but I solved my problem by changing- L.marker(LATITUDE,LONGITUDE).bindPopup("Info").addTo(map); to L.marker(L.latLng(LATITUDE,LONGITUDE)).bindPopup("Info").addTo(map);
