automatic image georeferencing in VE RRS feed

  • Question

  • Usually working with gis software, I recently played with mapcruncher. Interface is great to place matching points between personnal images and VE. Is it possible to "feed" directly VE with the known coordinates (available for example in a tfw or jgw) rather than pointing manualy each tie point? What we usually have is image top left set to 0.0, and we know this point coordinate is yyyyy lat; xxx long. The goal is to reference automaticaly my images that are already projected and georeferenced in wgs84.

    Merci

    thanks john and yes, Arc2Earth Publisher will export whatever you can load into ArcGIS as tiles for VE. There are some live samples on the blog here: http://www.spatialdatalogic.com/cs/blogs/brian_flood

     

    another cool sample is here: http://s3.amazonaws.com/arc2earth1533176949/noaa_nowcoast_live/veviewer.html

    It uses the A2E Scheduler to export the map hourly so the radar image is always the most current. It also sets the correct http expire headers so users will always see the correct tiles. The radar data comes from a NOAA ArcIMS service but it could be whatever datasource you wanted. Scheduler is completely customizable and runs outside of ArcMap. more info to come tomorrow...

     

    Arc2Earth Publisher goes on sale tomorrow (4/11/07) and there will be a 7 day free trial. There will also be a limited time discount for all purchases (new or upgrades)

     

    cheers

  • Absolutely David,

    UAV images on VE sounds very cool. We overlayed some aerial / satellite photography for Microsoft Australia for an event earlier this year:

    Integrating live images would be great. Your video looks like fun! It appears you have most of the work done already. Send me an email -  John at soulsolutions.com.au

    I'm sure we can get it working on Virtual Earth relatively easily. You probably know most of the benifits of VE over Google earth, I find the biggest being that people can see the images in there browser on your website and then with the same code if they want to install 3D that get a better experience still having your website not someone elses application.

  • I guess it is an issue of flexibility and performance, the technique VE uses allows for very large files to be integrated without performance issues - imagine a 4GB image, broken into 30KB tiles it is managable.

    Unfortunalty due to it only being early there a few tools around to help automate what needs to be done. Mapcruncher is great for one off layers, and in fact it can be run from the command line and automated. There is one third party tool, the plugin for ArcGIS which maybe of use:

    http://www.arc2earth.com/

    Or else you need to write code to do it, a simply httphandler that chops and resizes an image based on the quadkey is possible. You could build a tool that takes the image at the top left lat/long and does the rest automatically. These articles maybe of use:

    http://www.viavirtualearth.com/vve/Articles/RollYourOwnTileServer.ashx

    http://www.viavirtualearth.com/vve/Articles/WorldWind.ashx

     

    If this is not your expertise and need some help give me a yell.

  • hello

    thank you for these information.

    The soft we use now for GE has been developed with valery hronusov from russia and he did a great job with his team.

    I looked with great interest at Arc2Earth and seems to be a great solution.

    The problem we face now is how to handle image rotation to prevent black edges. It can be done with png quite easily but it takes some extra research. John I will certainly give you a yell because I think VE has a great potential for our company (PictEarth) and I do not have enough knowledge on VE to see all the issues.

    Biggest challenges are :

    - real time processing of images from our UAV (already done with our soft - possible link between kml and VE via Arc2earth ?)

    - automatic refresh of VE window (like network link in GE) every n second

    - handling large images

    If anyone is interested to face the challenge, my door is wide open

    Merci

     

    David
