[OSGeo-Discuss] offline maps
Hello OSGEO enthusiasts I would like to create, starting from the point where hard disk space is not a problem, a repository of raster maps that can be accessible offline, when for exemple, we have to go to the field and do georeference tagging and mapping. When in the field, there is no broadband internet or it's limited to 2.5G communication which is very slow, even for the best OGC server available. So, the ideia is to have a repository of maps, like the terrain maps offered online by google, for exemple, but I dont like the ideia of using the cache of google earth since all my work is done with QGIS and Geoserver. I know of some programs that are trial based that can do this but the images dont have any type of projection information with them. I end up with a bunch of images that cant be layed out on my current projection system. Is there a way of doing some kind of work with qgis in order to get this done correctly? Thanks for any kind of help. Carlos Sousa ___ Discuss mailing list Discuss@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/discuss

RE: [OSGeo-Discuss] offline maps
Hi, Is there more to this than loading the data and the data server technology onto a machine you take into the field and configuring the clients on that machine to use the local data and server technology? Do you take a network with you? You could for example network and rely on one server which talks to many client machines using that network? I don't know about using Google clients cached with Google data, but if the data is free, or you have license for use and can take them, I'm sure you can configure the client/servers so long as they too are open or you have a license for their use and are installable on the machines. Good luck Carlos!

Is it possible to detail a bit the software used and what kind of rasters there are in the repository. I thought I listed all the software I use. All my data are in either PostGIS/PostGres, or as files. I use shapefiles, geotiffs, regular images (gifs and pngs). I also have data in raw binary format that I manipulate with PDL (Perl Data Language, a scientific programming extension to Perl, kinda like IDL but free and open source). PDL allows me to query the raw binary data and also NetCDF data, and convert to images on the fly. The data served by a combination of Apache/MapServer. The browse client is coded in Perl (Perl Dancer and DBI), JavaScript (jQuery and OpenLayers) and CSS. I also use QGIS or uDig. The latter is more attractive, the former is more capable. Everything I need to use my data is on my laptop. I can disconnect Ethernet, turn off Airport, and happily see all my data.

Re: [OSGeo-Discuss] offline maps
Hello Ian and Kishor, It's strange you refer to google's TOS, which kinda reminds me of microsofts agreements on the stickers of original software, you have to buy but is never yours. To run around with the data in your cache isn't illegal? Anyways, I was wondering about other kinds of data freely available on the net, like yahoo's, usgs, nasa, etc. Aerial photographs that lie around the net are scarce but theres a large repository of ground based and altitude information that I don't know how to use and Kishor's solution is really cool but out of the reach of the non scientific realm, and for you average geek. Regarding geoserver, it's that easy to roll out tiff's at it because I have several free tif's and other generated from gdal's merge feature that he simply refuses to serve as wms. By the way I do use opengeo's and gisvm's solution for single laptop access to wms served data. Another problem is that there are alot of images that aren't georenferenced. Thanks for sharing your ideas.

Nothing strange about it. It has always been that way. Its just that there is more awareness of these issues. Almost all copyrightable material is never really yours, and when it is, there are limitations on what you can do with it. Even in the physical realm (atoms not bits) you can resell a book or a CD that you purchased, but you can't make a 1000 copies of it and resell all of those. In the digital realm (bits not atoms), you almost always pay for a license to use the thing not to own it. On top of that, stuff like EULA and TOS are contracts between you and the vendor/provider that you become party to soon as you click on that button or check that checkbox (I didn't read the long boring stuff is not a good defense). To run around with the data in your cache isn't illegal? Anyways, I was wondering about other kinds of data freely available on the net, like yahoo's, usgs, nasa, etc. Even if stuff is freely available on the net doesn't mean that it is free. There are limits to what you can do with it, and those limits are spelled out in the terms of service (or equivalent agreement). I am pretty sure that Google prohibits offline caching of their data. Aerial photographs that lie around the net are scarce but theres a large repository of ground based and altitude information that I don't know how to use and Kishor's solution is really cool but out of the reach of the non scientific realm, and for you average geek. It is not that difficult actually. Should you decide to do it, there is enough help available from the user community. That is the very nature of open source. You have to roll your sleeves and do some lifting, sometimes heavy, sometimes light, but always have to do some lifting. Regarding geoserver, it's that easy to roll out tiff's at it because I have several free tif's and other generated from gdal's merge feature that he simply refuses to serve as wms. By the way I do use opengeo's and gisvm's solution for single laptop access to wms served data. There you go. You already have a solution. Just learn more about it and use it to the fullest.
