Note : as it's impossible to load several thousands of markers directly with Google Maps, MIS has developed some tools to achieve this feature, allowing to set and run a geographical database (PostgreSQL/PostGIS) with all the data for order to only plot selective markers on the displayed map corresponding to the screen area.

Note : originally, MIS has developed in 2006 some multi-resolution mosaicking tools to keep high resolution pictures of large areas in Google Earth.
It seems there is some tricky behaviour in Google Earth concerning image overlays : all tiles fade out at the edges (global MIP map image processing tool chain issue concerning their client image overlay component ?); therefore the tiles are overlapping to get a seamless image...
But we have choosen to not artificially overlap the different mosaïc tiles (cheating in the original positions of the edges in the goal to conserve a seamless vision).
With the arrival of kml v.2, MIS proposes 'network links' GM or GE solutions with possibilities of including affordable web hosting solutions (>>> see GeoGarage ) to allow easy and speedy visualization of large overlay areas such as high resolution aerial orthophotos.

NEW : right now MIS proposes 'network links' GM or GE solutions with possibilities of including affordable web hosting solutions (>>> see GeoGarage ) to allow easy and speedy visualization of large overlay areas such as high resolution aerial orthophotos.
MIS has created some network links from the original file from Brest Metropole Océane.
(1.573 gigabytes in ECW format / 11.25 gigapixels image -125000 x 90000 pixels-)
Update : in November 2008, SHOM has removed their folder of pictures from their website.
So, our kmz network link is no more operational for viewing the demo pictures.

Note : MIS has originally developed in 2006 some image manipulation and editing tools (borders'crop) for BSB nautical chart plus image reprojection
The original chart has been cut horizontally in several pieces to keep its original resolution in GE v.3 because of the size of the raster chart leading to significant slowdowns : waiting a possible implementation in Google Earth of ISO-standard JPEG2000 image compression format storing geo-location metadata (using for example some KMLJP2 implementation such as GMLJP2 OpenGIS GML grammar...)
NEW : right now with kml version 2.1 and superoverlay features of GE v.4, MIS proposes 'network links' GM or GE solutions allowing to fetch KML data from remote servers.
MIS offers affordable web hosting solutions (GeoGarage) to allow easy and speedy visualization of large overlay areas such as very high resolution maps.

About 1018 NOAA raster nautical charts (RNC/BSB/KAP format) stored in the GeoGarage can be viewed online with Google Maps (public access) or Google Earth (private access) with advanced quilting process (mosaic image with removed borders -map collars- for a seamless rendering display of multiple charts).
So the user can access through Google viewers to all the range of NOAA raster maps, zooming in and out, panning in a continuous way for selecting the specified map scale automatically (so the appropriate map), by simply sliding the mouse roll.

with GM classical solution :
crude display when zooming
with the GeoGarage solution :
perfect display at larger scales
11/21/2006 : Google gives the ability to show simple kml/kmz files (as made in GE) in GM : so you can add your own imagery directly on top of GM. To view a kml or kmz file on GM, just go to GM, and instead of searching for a geographical address, search for a complete web address (including the "http://" part) of your kmz file.
But this is only OK for crude display of low-resolution raster files and with some approximated geo-positionning : GM uses Mercator projection and GE Plate Carrée (geographical) projection
NEW : as the size of the chart is important, you will see it's quite long (or even impossible) to view the map using kml embedded raster file solution : so the basic overlayer in GM is not appropriate in this case without any raster tiling solutions.
That's why MIS has developed the GeoGarage spatial image server solution which can also be associated to the Google Maps viewer : raster charts tiling solution, with hosting possibilities.
In March 2010, Magic Instinct Software has launched Marine GeoGarage, the nautical charts web portal
Our website is dedicated to any sailor or mariner who plans to study his next trip at sea, comfortably installed at home.
Marine GeoGarage has figured out a way to overlay a complete set of nautical raster charts over Google Maps.
So nautical charts can be viewed online with advanced quilting process (mosaic image with removed borders -map collars- for a seamless rendering display of multiple charts), zooming in and out, panning in a continuous way for selecting the specified map scale automatically (so the appropriate map), by simply sliding the mouse roll, with full transparency management via layer opacity sliders (for terrestrial maps and orthophoto overlay) and Google local search (marinas, harbour services...)
Marine GeoGarage proposes a feature (without any Login process) where the user can drop waypoints and create custom routes but which can also be saved if the user asks for a free account.
What is really cool about the site is that you can export out those saved routes and move them over directly to your Garmin GPS unit via the Garmin Communicator Plugin.
Marine GeoGarage is world's first nautical charts web portal -with data directly coming from International Hydrographic Services- built as a Software as a Service (SaaS) available in free and pay-per-use model.
What Marine GeoGarage changes is the concept of nautical electronic charts viewing:
you don't "own" anymore the charts, just "use" them and share them, anytime, anywhere you are via computer, mobile phone or any other Internet enabled personal device.
The Cloud computing part of the service provides some resources in back-end to ensure regular processes for updating the charts (more than 3500 today) coming from the following international Hydrographic Services :

Note : MIS has developed some georeferencing tools for Olex screenshots and for Olex user data.
If you are an Olex user, you can get the Ruter2kml converter allowing the visualization of your own user data (marks, tracks, routes, lines, areas) in Google Earth
Note : Chris Parsons has improved the process using some Perl+ImageMagick code to to grab the image, copy the same image over the alpha channel and save it as a png : try Global transparent cloud map. He makes it nicer modifying the satellite images to put transparency where there are no clouds (so the Earth comes through clearlier).
