Hello everyone, here’s my tenth report for the OL3-Google-Maps project.

Link to the library: https://github.com/mapgears/ol3-google-maps

What did you get done this week?


   Added support for map rotation. It’s not perfect as the window resize
   event doesn’t work when the map is rotated, but the controls work
   correctly. There isn’t a “good” way to implement it since Google Maps
   doesn’t support rotating maps.

   Added support for minResolution and maxResolution. Layers now stop
   displaying when the current zoom level is outside the ranges set for that

   I added options to disable the replication of image and tile layers to
   Google Maps. I also made an example demonstrating these, as well as
   unmanaged vector layers.

   I worked on my integration test of OL3-Google-Maps into an existing
   project. I found another bug that I solved in the library, but there’s
   still 2-3 issues that I haven’t solved yet.

What do you plan on doing next week?


   I will add some cool examples such as maps using an overview map or
   Google StreetView.

   In my integration test, tiled WMS layers appear at the wrong place on
   the map. It has something to do with the way I translate coordinates from
   OpenLayers 3 to the Google Maps API. I will work on this problem next week.

   ImageWMS layers don’t refresh themselves after being modified. I will
   implement a way to notify the layers that the image they rendered is no
   longer valid and needs to be refreshed.

Are you blocked on anything?



Have a nice week-end!
